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 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.
