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:

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.

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

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

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

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

Sweating
![Page 22: Nursery Production 4](https://reader038.vdocuments.us/reader038/viewer/2022102714/56816725550346895ddbb7b0/html5/thumbnails/22.jpg)
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.
![Page 23: Nursery Production 4](https://reader038.vdocuments.us/reader038/viewer/2022102714/56816725550346895ddbb7b0/html5/thumbnails/23.jpg)
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.

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)

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.
