August 26, 1983 – Effective August 26, 1983
Emergency Regulation
This rule adopted pursuant to the authority granted the commissioner of agriculture under Title 35,
Section 111, C.R.S. 1973, as amended.
House Bill No. 1242 became law on July 1, 1983. It mandates that the commissioner shall establish a
minimum charge per inspection, determine the cost of inspections and establish the charge therefore by
rule or regulation. Inspections may not be performed until this charge is established. The nursery law
mandates that each nursery be inspected at least once a year. The season of the year dictates that these
inspections be made in September when trees are still in leaf and actively growing. If this emergency
regulation is not adopted at this time, inspections may not be performed until after October 30.
Approximately one hundred twenty nursery inspections must be made. These inspections provide
consumer protection and make it possible for Colorado nurserymen to export their stock into other states.
The immediate adoption of rule 26-5.1 is imperatively necessary for the preservation of public health,
safety and welfare, and compliance with the requirements of the Administrative Procedures Act would be
contrary to the public interest.
12.2
August 26, 1983 – Effective October 30, 1983
These regulations are adopted pursuant to the authority granted the commissioner of agriculture under
Title 35, Section 111, C.R.S. 1973, as amended

August 26, 1983 – Effective October 30, 1983
These regulations are adopted pursuant to the authority granted the commissioner of agriculture under
Title 35, Section 111, C.R.S. 1973, as amended.
The purpose of these regulations is to protect consumers of the state of Colorado and to prevent the
spread of weeds by regulating labeling of the weed content in turfgrass sod, to protect consumers by
standardizing measurement methods for machine-dug trees, and to set fees for inspections required by
the Colorado Nursery Act.

12.3
January 28, 1987 – Effective March 30, 1987
Section 35-26-106, C.R.S., as amended, mandates that the commissioner shall, by rule or regulation,
establish a charge for the actual cost incurred in making inspections. Costs have increased since the
original fee of fifteen dollars per hour was established in 1983. It has therefore become necessary to
increase the fee to eighteen dollars per hour, based on current costs, to meet this mandate.
12.4
August 27, 1987 – Effective October 30, 1987
Section 35-26-106, C.R.S., states the maximum inspection fee per inspection, which is one hundred fifty
dollars, effective July 1, 1987. There is no need to state this maximum in the regulations since it is in the
statute. This Section also requires that the commissioner shall, by rule or regulation, establish a license
fee for each place of business, not to exceed one hundred dollars. The combination of license and
inspection fees received annually must cover the complete cost, direct and indirect, of the nursery
licensing and inspection program
d to state this maximum in the regulations since it is in the
statute. This Section also requires that the commissioner shall, by rule or regulation, establish a license
fee for each place of business, not to exceed one hundred dollars. The combination of license and
inspection fees received annually must cover the complete cost, direct and indirect, of the nursery
licensing and inspection program. It is anticipated that there may be a ten percent dropoff in the number
of licensees from the previous year because of homeowners, not in business, who buy licenses to get
wholesale prices and businesses which handle a very small amount of nursery stock and may stop selling
it. Based on this reduced number of licensees and taking into consideration projected inspection fee
revenue, a license fee of sixty dollars should provide the needed revenue.
12.5
May 20, 1988 – Effective June 30, 1988
Section 35-26-111 authorizes and directs the commissioner to promulgate such rules and regulations as
he may deem necessary and proper for the furtherance and enforcement of the provisions of the
Colorado Nursery Act. Section 35-26-104(2) states that the grade or size shall meet the specifications
established by rules or regulations. Members of the 1986-87 Nursery Advisory Committee made
suggestions for changes to existing ball size requirements that they felt were warranted, based on their
experience as growers and sellers of nursery stock in this state. They particularly felt that separate
specifications were needed for collected aspen trees, since their root systems are different from most
other deciduous trees, especially in that they are shallower. The Department of Agriculture agrees with
these suggestions and adopts same as also reflecting the position of the Department of Agriculture.
Examples of the different types of trees are included at the top of each type chart, rather than at the end
of all the charts, in order to make the charts easier to interpret

12.6
October 18, 1991 – Effective November 30, 1991
The following rules are hereby promulgated under the authority of the Colorado Nursery Act, Sections 35-
26-101 to 115, C.R.S. (1984 and 1990 Supp. as amended by Senate Bill 91-65). They deal with four
different sections, including changes to two sections and creating two new sections.
The ball size specifications for bench packed stock are given in two different sections of the Rules and
Regulations, due to an error made at an earlier time. The most appropriate specifications are found in
subsection 26-3.6, which refers to specifications for bare root stock. This more closely applies to bench
packed stock than the specification given in subsection 26-2.13, which refers to specifications for balled
and burlapped stock. Bench packed stock is bare root stock with the roots packed in a growing medium
mixture and is not dug with root system and soil ball intact as is balled and burlapped stock. Subsection
26-2.13 is therefore repealed.
Inspection fees are raised from eighteen dollars per hour to twenty dollars per hour to cover increases in
the cost of performing inspections. Amendments to the Colorado Nursery Act changed the word license to
registration. This requires the establishing of a registration fee to take effect on January 1, 1992. This fee
is raised from the most recent license fee, sixty dollars, to seventy-five dollars to cover increasing costs of
administering the program.

The Colorado Nursery Act specifies that rules and regulations be promulgated to give requirements
concerning evidence of authorization to have collected nursery stock in the possession of nursery stock
collectors. A new section 26-6.0, is created to serve this purpose.
Also specified by the Colorado Nursery Act are rules to establish minimum standards for the qualification
of individuals who are authorized to make inspections as agents of the Commissioner who are not
employees of the Department of Agriculture. A new section, 26-7.0, is created, requiring that persons
seeking to contract with the Department shall demonstrate knowledge to meet the minimum standard by
successfully passing an examination. The Colorado Nursery Act states that the Commissioner may
charge a fee for qualifying such persons as inspectors. Section 7.0 establishes that fees shall be set to
cover all costs of qualifying such persons.
12.7
September 17, 1993 – Effective October 30, 1993
The following rules are hereby promulgated under the authority of the Colorado Nursery Act, pursuant to
Section 35-26-111, C.R.S. (1984). They deal with balling and burlapping specifications.
The statement is made in subsection 26-2.11, dealing with ball diameters for nursery grown stock, that
ball diameters shall be measured six inches below the soil line on stock dug by a mechanical spade. This
statement is amended to add the word “original” to define “soil line”. The original soil line is at the trunk.
The edges of the ball may be tapered off and measuring from the edge would give a different depth than
from the original soil line at the trunk
diameters for nursery grown stock, that
ball diameters shall be measured six inches below the soil line on stock dug by a mechanical spade. This
statement is amended to add the word “original” to define “soil line”. The original soil line is at the trunk.
The edges of the ball may be tapered off and measuring from the edge would give a different depth than
from the original soil line at the trunk.
The table in Section 26-2.11, Type 2, is amended to give required minimum ball diameters in relation to
height or caliper for trees in this type, such as pine and spruce. Caliper represents a more accurate
indicator of tree growth than does height, for coniferous evergreen trees of this type.
12.8
January 19, 1995 – Effective March 2, 1995
The following rule is hereby promulgated under the authority of the Colorado Nursery Act, pursuant to
Section 35-26-111, C.R.S. (1984) and Section 35-26-106(3), C.R.S. (1994 Supp.)
This rule sets the charge per hour per inspector for inspections made pursuant to the statute. The statute
requires that actual cost incurred in making inspections be determined and a charge therefore be
established. Actual costs have increased since the most recent charge was established. A new charge for
inspections is therefore established in amendments to this rule.
12.9
September 8, 1995 – Effective October 30, 1995
This amendment to the rules and regulations is adopted pursuant to the Colorado Nursery Act, § 35-21-

1.
Add and delete plant species to/from the list of prohibited weeds that shall not be sold as nursery
stock in Colorado.
Factual and Policy Issues:
The factual and policy issues encountered in proposing these amendments are as follows:
1.
In 2001, the Colorado Department of Agriculture revised the state noxious weed list pursuant to
35-5.5-115 and added and deleted a number of newly recognized noxious weed species.
2.
These species are required to be managed on lands of the State of Colorado.
3.
The continued sale of these species as plant materials or as contaminants to plant materials
presents a threat to the agricultural and environmental systems of Colorado.

Purpose:
The purpose of this rulemaking is to update the specifications for balled and burlapped nursery stock
balled to be consistent with the American Standard for Nursery Stock where appropriate, provide for
enforcement of the prohibited weed rules by local governmental entities and update the prohibited weed
list to mirror the Colorado noxious weed law.
Factual and Policy Issues:

balled to be consistent with the American Standard for Nursery Stock where appropriate, provide for
enforcement of the prohibited weed rules by local governmental entities and update the prohibited weed
list to mirror the Colorado noxious weed law.
Factual and Policy Issues:
The factual and policy issues encountered in the proposal of these permanent rules are as follows:
(1)
The American Standard for Nursery Stock as adopted by the American Nursery and Landscape
Association has changed several of the standards for balled and burlapped nursery stock. In
order to facilitate interstate movement of nursery stock it is necessary to have similar standards
between states as appropriate based on climatic conditions.
(2)
Some local governmental entities, primarily weed districts, have a vested interest in prohibiting
the sale of weeds. Some of these entities wish to take an active role in inspecting and enforcing
against nursery dealers that attempt to sell prohibited weeds as defined in part 9.0. Providing a
mechanism to allow them to perform these functions is also advantageous to the Colorado
Department of Agriculture. This process provides the ability to inspect and take action in remote
areas that the Department may not be able to reach except a few times per year.
(3)
The noxious weed list has been modified to remove species considered native to Colorado or are
so widespread that it is impossible to obtain statewide control. The prohibited weed list is being
changed to parallel these changes.

These amendments to the rules are proposed for adoption by the Commissioner of the Colorado
Department of Agriculture (“CDA”) pursuant to his authority under the Colorado Nursery Act (the “Act”), §

Purpose
The purposes of these proposed rule amendments are as follows:
1)
To increase the nursery registration fee from $80 to $90.
2)
To require records be kept of all nursery stock imported into the State of Colorado.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1)
The nursery fund balance has been near zero for the past two years. Revenue from registration
fees has been flat and has not kept up with the increases in operating expenses such as personal
services and fuel costs since the last increase. Although the program is a cash funded program,
the revenue generated does not cover the actual costs of the program and therefore the program
is subsidized by general funds.
2)
The registration fee is capped in statute at $100 (35-26-106(1) C.R.S.)

CODE OF COLORADO REGULATIONS
8 CCR 1203-5
Plant Industry Division

15
3)
35-26-106(1) C.R.S. provides that the Commissioner shall, by rule or regulation, establish a
registration fee for each place of business.
4)
The Colorado Nursery and Greenhouse Association supports this increase in the registration fee.
5)
The average number of nursery registrations per year is 1,700. Therefore this increase will
generate an increase in revenue of $17,000 for the program.
6)
Registration fees have not been increased since November 1999.
7)
For several decades it has been known that movement of nursery stock is a primary mechanism
of movement and introduction of plant pests. In recent years it has become very apparent that
new plant pests are moving into the State on nursery stock. Japanese beetle is an excellent
example. It was introduced into a small area in the Denver Metro area and has now become
established in two other areas

new plant pests are moving into the State on nursery stock. Japanese beetle is an excellent
example. It was introduced into a small area in the Denver Metro area and has now become
established in two other areas. It is a significant pest in these locations. Emerald Ash Borer is
another example of a devastating pest that has moved into many states in the east and mid-west
but has not been found in Colorado yet.
8)
In order to document stock that is moving into the state so that pest surveillance activities and
inspections can be conducted in the most efficient manner possible, the nursery registrants that
are importing stock need to be required to keep records that the Department can review.
9)
35-26-108(1)(b) C.R.S already provides that “At any time during regular business hours, the
Commissioner shall have free and unimpeded access upon consent or upon issuing or obtaining
an administrative search warrant to all records required to be kept at any reasonable time and
may make copies of such records for the purpose of carrying out any provision of this article or
any rule made pursuant to this article.”
10)
A Japanese beetle quarantine is being proposed to lessen the pressure of Japanese beetles
being transported into the state on nursery stock. These record keeping regulations will assist
with enforcement of this quarantine.

Statutory Authority
These amendments to these rules are proposed for adoption by the Commissioner of the
Colorado Department of Agriculture (“CDA”) pursuant to his authority under the Colorado Nursery
Act (the “Act”), § 35-26-111 C.R.S.
General: This if the first major update of the Rules Pertaining to the Administration and
Enforcement of the Colorado Nursery Act since 1973. The update was conducted to reflect
current industry changes, to remove unnecessary and unenforceable language and ensure that
the rule is easily understood by the regulated community and CDA staff. These revisions
incorporate changes as a result of the Department’s Regulatory Efficiency Review process
conducted in accordance with the Governor’s Executive Order D 2012-002.
The purpose of these proposed rule amendments are as follows:
Delete definitions and statements that are duplicative; add definitions and wording to clarify the
intent of the rule and enforceability; delete unnecessary or confusing language; delete grading
standards that are unenforceable and considered 'best management practices'; correct grammar;
add plant species to the list of prohibited weeds to parallel changes made to the current noxious
weed act; and to change the title of the rule removing the word “regulation”.
Factual and policy basis issues encountered when developing these rules include:
Part 1.0
1.
Definitions added:
-
1.4 “bedding plants” was added to clarify the CCR definition of nursery stock.
Nursery stock is defined in the Act § 35-26-102(14), C.R.S., and '….does not
mean …bedding plants, annuals,…'
-
1.9 “fibrous roots” was added to clarify what “established in the container” means
under rule 3.0 “condition of nursery stock”.
-
1.10 “girdling” was added to clarify that it constitutes a 'dead or dying condition'
which is a prohibited act, § 35-26-105(a) C.R.S. The plants’ conductive tissue,
called cambium, contains the xylem and phloem in which fluids and nutrients are
transported between the roots and foliage
ts” was added to clarify what “established in the container” means

-
1.10 “girdling” was added to clarify that it constitutes a 'dead or dying condition'
which is a prohibited act, § 35-26-105(a) C.R.S. The plants’ conductive tissue,
called cambium, contains the xylem and phloem in which fluids and nutrients are
transported between the roots and foliage. Severing the cambium restricts and
/or prevents the flow of these resources. Over time the plant dies from lack of
fluids.
-
1.11 “girdling root” was added to help clarify a condition in which the woody plant
is left in a container too long and the root begins to encircle the root ball or
container. Over time it will cause the plant to die from lack of water and nutrients.

-
1.14 “mechanical injury” was added to define what the Department considers to
be a mechanical injury and that it constitutes a “dead or dying condition” when it
significantly impairs the viability of the plant.
2.
Definitions deleted:
-
26-1.8 “potted stock” was deleted because the definition is adequately covered in
2.5 (specifications for balled and potted nursery stock), 2.4 (specifications for
balled and potted nursery stock) and 3.2 (container grown nursery stock).
-
26-1.10 “prohibited weeds in turfgrass sod” is not a definition. Prohibited weeds
are adequately covered in 3.5 “condition of nursery stock/turfgrass sod”.
-
26-1.16 the definition of “sell or offer for sale” can be found in the dictionary. It is
also covered in the Act, § 35-26-106(1) C.R.S.
Part 2.0
1.
Rules deleted:
-
26-2.3 “evergreens” was deleted because the specifications describe a specimen
tree. Trees that are slightly less than specimen quality will still establish in the
landscape as long as the root system is adequate.
-
26-2.6 “fruit trees” and 26-2.7 “fruit tree seedlings” were eliminated to reduce
redundancy

redundancy. Fruit trees and seedlings are included in root ball standards for
deciduous trees (2.4).
-
26-2.8 “small fruits” was eliminated due to lack of necessity. Specifications listed
did not have bearing on establishment.
-
26-2.9 “lining out stock” was eliminated because liners are rarely sold to the
public, they are sold to professionals who know what quality it necessary.
-
26-2.10 “seedling trees and shrubs” was eliminated to reduce duplication. These
specifications are taken care of in bare root, container and balled and burlapping
standards.
2.
Changes made:
-
Changes to rules 2.1 and 2.2 were made to address current industry standards.
The specifications previously listed are 'best management practices' which are
not enforceable.
-
Changes to rule 2.3 “rose grades” were made to correct grammar and increase
clarity. Grade specifications were deleted for field grown miniature roses. These
plants are not seen often in the trade in Colorado. Many miniature roses and tree
roses are used as patio plants and gift plants and must be protected in the
winter.
-
2.4 “specifications for balled and burlapped nursery stock” and 2.5 “specifications
for balled and potted nursery stock” were changed to correct grammar; caliper
measurements; and describing where the caliper will be measured was moved
from 2.1.

-
The deciduous tree specifications in 2.4 now include specifications for fruit trees,
collected stock and small and large deciduous. The caliper specification greater
than 9 inches was added.
-
Upright coniferous section in 2.4 was edited to include upright juniper, arborvitae,
pine, spruce, fir and collected stock. Height vs. caliper ratios were deleted for
clarity and consistency, and improved enforcement.
-
Eliminated spreading, semi spreading cone, broad upright evergreens to
combine into one category “broadleaf evergreens”- most of these plants are
shrubs in our climate ; height standards are more appropriately used, therefore
caliper standards were eliminated.
-
Eliminated ball diameters for collected nursery stock per advisory committee
recommendations. Collected stock root balls will be treated the same as nursery
grown stock. It is generally recognized that plants growing in their native state will
sustain a much more severe shock when transplanted than the same kinds of
plants when nursery grown. If collected material is moved, a considerably larger
ball than that previously recommended is required, because the unrestricted root
development and the varying conditions of soil in which such material is found.
-
2.16 combines slow and fast growing species to one specification; designations
of greater than 4 feet were added and bag diameter was increased per advisory
committee recommendation to that of 25% smaller than the correlating balled
and burlapped specification.

Rules added:
-
3.1 “mechanical injury” was added to prohibit sale of nursery stock damaged by
injury such as girdling that might be caused by a foreign object or circling root
that produces a visible indentation or wound that cuts into the trunk or stem
deeply enough to constrict the plants conductive tissue in a manner that restricts
or prevents the normal flow of fluids.
3.
Changes made:
-
3.2 “container grown stock” was changed to correct grammar and add a

The purpose of these proposed rule amendments are as follows:
1.
Delete Rule 2.4 Specifications for Balled and Burlapped Nursery Stock.
2.
Delete Rule 2.5 Specifications for Balled and Potted Nursery Stock.
3.
Delete Rule 2.6 Specifications for In Ground Fabric Bag Grown Nursery Stock.
Factual and Policy Basis issues encountered when developing these rules include:
1.
Changes to Rules 2.4, 2.5, and 2.6 were made under the efficiency review process in
2012 of the Nursery Act to allow for consistency in enforcement.
2.
During an information and education period, Nursery Industry from within and outside
Colorado brought up concerns that the restrictions on root ball sizes made in 2.4, 2.5 and
2.6 were too strict and were prohibitive to many outside of the State of Colorado.
3.
Two meetings were held with industry representatives and the CNGA Board of Directors
to discuss the concerns of the industry.
4.
No other states enforce root ball restrictions.
5.
Root ball sizes were determined to be best management practices best suited for
industry and market place adjustment and not regulatory enforcement. In order to be
enforceable the root ball restrictions had to be narrow and were too restrictive to
business.
6.
The CNGA Board of Directors advised that CDA remove root ball restrictions from the
Rules. Root ball restrictions are best management practices, too variable and
unenforceable

In order to document stock that is moving from quarantined areas of the state and to conduct pest
surveillance activities and inspections in the most efficient manner possible, nursery registrants
that are importing stock must keep records from any origin so that the Department can review
those records as needed.

Statutory Authority
These amendments to the rules are proposed for adoption by the Commissioner of the Colorado
Department of Agriculture (“CDA”) pursuant to the authority under § 35-26-111 C.R.S. of the Colorado
Nursery Act (the “Act”).

Nursery Act (the “Act”).
The purpose of these proposed rule amendments is as follows:
1.
Change the inspection fee hourly rate from $30.00/hour to $45.00/hour.
The factual and policy issues encountered when developing these rules include:
1.
The Colorado Department of Agriculture is required by § 35-26-106(3), C.R.S., to charge for the
actual cost incurred in making inspections. Over time, the average personnel cost of an
inspection has increased to approximately $39/hour, while the operating costs associated with an
inspection (e.g., travel, fleet) have increased to almost $24/hour. Although CDA has data to
support an increase to approximately $63/hour for the actual cost of an inspection, CDA is
proposing to increase the cost to $45/hour. This increase will allow CDA to defray the majority of
the cost to perform inspections as part of the Nursery Program.
2.
The inspection fee has not increased since 2009, and costs incurred to complete inspections
have increased significantly over the past ten years. to allow the nursery program to function
effectively and to implement program goals, CDA must raise fees associated with inspections.
12.20
Adopted September 17, 2019 – Effective October 30, 2019
Statutory Authority
These amendments to the rules are proposed for adoption by the Commissioner of the Colorado
Department of Agriculture (“CDA”) pursuant to the authority under § 35-26-111, C.R.S., of the Colorado
Nursery Act (the “Act”).
The purpose of these proposed rule amendments is as follows:
1.
Increase the registration fee from $90.00/year to $170.00/year.
The factual and policy issues encountered when developing these rules include:
1.
The Nursery Program is comprised of three main parts. The first is the registration of all persons
engaged in the advertising for sale or selling of nursery stock. The second is risk-based
inspections of nurseries, nursery dealers, and turf farms who import from Japanese beetle-
quarantined areas
ear to $170.00/year.
The factual and policy issues encountered when developing these rules include:
1.
The Nursery Program is comprised of three main parts. The first is the registration of all persons
engaged in the advertising for sale or selling of nursery stock. The second is risk-based
inspections of nurseries, nursery dealers, and turf farms who import from Japanese beetle-
quarantined areas. The third is issuance of inspection certificates without which export of
Colorado nursery stock and live plant products to other states would be impossible. Through the
registration, inspection, and certification process, the Nursery Program ensures that nurseries
produce and distribute healthy plants.
2.
CDA is required by § 35-26-106(1), C.R.S., to charge a registration fee for each separate nursery,
store, stand, sales ground, lot, or any location from which nursery stock is being sold, offered for
sale, or distributed. Although the cap for registration fees is set at $300, the registration fee has
been $90 since 2009.

3.
Costs incurred to administer the Program have increased significantly over the past ten years
given inflation rates, year-to-year increases in wages, and other costs necessary for maintenance
and implementation of the Program. Specifically, the cost of administering the Program over the
past decade has increased approximately 35%. Current registration fees do not meet operational
requirements. Because the registration fees account for 88% of the Program’s annual revenue,
CDA has proposed an increase in annual registration fees to $170, which will allow the Program
to function effectively, meet Program goals, and better administer various Nursery Program
components (e.g., enforcement of quarantines).
