  2. Soil Preparation

  3. Since every nursery operation is unique, there is no single, correct way to prepare the soil prior to planting. • The following field implements are used by nurseries to prep the soil:

  4. Subsoiler • Long, thin knives. • Penetrates deep into the soil. • Rips out the root systems of previous crops. • Loosens the tracks left by harvesting equipment. • Improves water percolation and aeration.

  5. Spring tooth Harrow • “Finishing” tool used to level a field prior to planting.

  6. Chisel Plow • Usually used in the Fall. • Leaves the soil in a “rough” condition. • Freeze-thaw cycles during the winter break down soil clods.

  7. Disk • “Finishing” tool used to prepare a field for planting. • Levels the field.

  8. Howard Rotovator • Rototiller attachment for a tractor. • Pulverizes the soil. • Used to incorporate green manures. • Can also be used in field prep.

  12. Preparing Bare-root Liners for Planting • Generally speaking, the roots and tops of the liners are pruned prior to planting. • Treat the roots of the liners to prevent them from drying out until they are planted: • Mud slurry • Gel-based root dips

  14. Sweating

  15. Most bare-root tree and shrub liners can be stored in refrigerated cold storage all winter and develop normally when planted or potted in the spring. • There are a few species, though, whose buds become extremely dormant during storage. • These species must be forced into breaking bud before they are lined out. This process is called sweating.

  16. Methods Used to Sweat Plants • Place plants in a warm, humid greenhouse or polyhouse. • Use a shed or garage that can be kept between 60 – 70 degrees F. • Lay out a bed of straw on the floor. • Lay the bundles of plants side-by-side on the straw and moisten them with water. • Cover the bundles with straw and moisten with water. • Check the plants daily for bud break. • Line-out after they have broken bud.

  18. Plant genera which may need sweating… • Amelanchier - Serviceberry • Betula - Birch • Berberis - Barberry • Carpinus - Hornbeam • Celtis - Hackberry • Cercis - Redbud • Crataegus - Hawthorne • Morus - Mulberry • Potentilla - Cinquefoil • Pyrus - Pear • Quercus - Oak • Rosa - Rose • Salix – Willow (Weeping)

  19. Preparing Potted Liners for Planting • Prune the tops of the liners. • Thoroughly water the liners prior to planting. • Remove plastic containers prior to planting. Biodegradable peat pots are not removed prior to planting. • If needed, break apart the root mass to prevent circling roots.
