Soil Preparation

Slide3

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:

Slide4

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.

Slide5

Spring tooth Harrow

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

Slide6

Chisel Plow

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

Slide7

Disk

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

Slide8

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

Slide22

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.

Slide23

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.
