Nursery stock shall mean all field-grown or container-grown perennial plants,
including, but not limited to, vegetative or propagative parts or perennial plants dug from the
wild, so labeled and distributed. This stock excludes, among other things, greenhouse plants
grown for indoor use, annual plants, biennial plants, florist stock, cut flowers, sod, turf, onions,

Inspection Of Dealers
The inspections of dealers' and growers' of nursery stock and the associated reports issued is
authorized by Neb. Rev. Stat. Sections 2-1091; 2-1092; 2-1093;
2-1094; 2-1095; 2-1096; 2-1097; 2-1098; 2-10,100; 2-10,101; 2-10,102; and 2-10,115 of the Act.
- Nursery stock should be accessible during regular business hours to the Department for
inspection. Weeds or other growth which may hinder a proper inspection shall be grounds to
suspend or withhold any license or be cause for reinspection.
- Inspection reports issued to dealers will outline the violations involved and corrective
actions to be taken including Withdrawal-From-Distribution orders which would specify nursery
stock that is restricted and can't be distributed.
Storage, Care, And Display Of Nursery Stock
Nursery stock shall be displayed or stored up off the concrete, asphalt, or other similar hard
surfaced areas on pallets or on bark or other moisture-retaining/heat-reducing material. Roots
shall be protected from excessive heat, drying, and other adverse conditions.
Balled and burlapped stock shall be kept moist at all times and in a moisture-retaining material at
a depth significant to cover approximately 75% of the ball.
Bare root stock shall be kept under conditions of temperature, light, and moisture to retard
etiolated (bleached as the result of the exclusion of light) or other abnormal growth and maintain
viability. Moisture shall be supplied to the root system by high humidity conditions in storage or
by covering the roots with moisture-retaining material. The roots of healed-in-stock must be
covered by a moisture-retaining material.
Bench balled stock shall be kept moist at all times and in moisture-retaining material at a depth
significant to cover approximately 75% of the ball.
Container-grown, potted, and balled-and-potted stock shall be kept and displayed under
conditions of temperature, light, and moisture significant to maintain the viability and vigor of
the nursery stock. Potting media shall be maintained at the depth significant to cover all roots of
the plants.
Packaged stock shall be stored and displayed under conditions of temperature and light that will
retard etiolated growth or other abnormal growth and ensure adequate moisture.
Standards For Viability Of Nursery Stock Distributed
All nursery stock distributed by dealers and growers shall meet the following standards of
viability. Stock not meeting those minimum standards or viability shall not be offered for
distribution. The authority to set viability standards for nursery stock distributed by dealers and
growers is found in Neb. Rev. Stat. Sections 2-1096; 2-1097; 2-1098;
2-10,101; 2-10,102; and 2-10116 of the Act.
- Woody stemmed deciduous stock shall have moist green cambium in the stems and branches
and shall have viable buds or normal green, unwilted growth. Etiolated growth from individual
buds shall not be more than four inches.
- Rose bushes shall have moist green cambium in each cane at least six inches above the graft.
Etiolated growth from individual buds shall not be more than four inches.
- Balled and burlapped stock shall have moist, green cambium in the stems and branches and
shall have viable buds or normal green, unwilted growth. Etiolated growth from individual buds
shall not be more than four inches. Balled and burlapped nursery stock shall have secure earth
balls that shall meet or exceed the size specified by the American Standard for Nursery
Stock.
- Herbaceous perennials shall not be wilted or in such condition indicative of subnormal
viability.
- Colored waxes or materials used to coat the aerial parts of plants which change the
appearance of plant surface so as prevent adequate inspection are prohibited.
- Nursery stock with plant pest infestations or serious damage as a result of plant pest
infestations shall not be distributed.
- Nursery stock distributed by dealers, growers, and collectors, and those with optional
inspections shall not contain actively growing weeds.
- Nursery stock environmentally or mechanically damaged shall not be distributed if normal
growth and development would be inhibited. Examples include, but are not limited to, cultivator
damage, deer damage, rabbit damage, hail damage, sunscald, and frost cracks. Nursery stock
will be ordered destroyed if 40% or greater of the cambium layer of the trunk or crown is
damaged. If 20 to 40% of the cambium layer of the trunk or crown is damaged, nursery stock
may be withdrawn from distribution.
- Nursery stock shall not be distributed with plastic burlap. All other nondecomposing
material enclosing balls of soil and all nursery stock bound with plastic rope, shall be untied
when active growth begins. Rope used to tie up the branches of trees shall be removed when
active growth begins.
- Any plant not meeting the above criterion may be pruned to remove dead or damaged
branches and canes or etiolated growth and may then be distributed.
Labeling And Shipment Of Nursery Stock
- The proper labeling and record keeping of nursery stock distributed and received by dealers,
growers, collectors, and those with optional inspections is authorized by Neb.
Rev. Stat. Sections 2-1091.01; 2-10,106; 2-10,108; and 2-10,116 of the
Act.
- All nursery stock distributed in Nebraska shall be individually labeled with the correct
common name or botanical name and the place of origin of nursery stock. An exception to this is
that container grown or potted nursery stock of one gallon or less is not required to have an
individual place of origin label.
- Place of origin labels may be in code, provided the Department is given access to the
code.
- All collected nursery stock shall be labeled as collected.
- When grade classifications are declared, they shall be in accordance with those adopted by
the Department in addition to the requirements of the Act.
- When nursery stock is distributed in a group or bundle of the same species and variety, a
label on the group or bundle shall be an adequate label. When nursery stock is planted, the label
may be omitted if the nursery stock is listed on the invoice or receipt.
- When nursery stock is from a quarantined area, the shipment must include the proper
documentation and compliance labeling of any applicable federal or state quarantines.
- Dealers, growers, collectors, brokers, and those with optional inspections shall maintain for
three years shipment records, packing slips, and other records of: (1) the name and address of
any person from which nursery stock was received and the receiving date; (2) the name and
quantity of the contents; the place of origin; and (3) a license or its equivalent issued by the
recognized, authorized agency stating that the nursery from which the nursery stock originates
has been inspected.
