Pests in Gardens and Landscapes

Rootbound plant
Avoid plants that are excessively rootbound

Plant properly

Container-grown woody plants can be transplanted any time of year, but planting in fall through spring is ideal. Dig a shallow hole and set the plant on settled ground in the center of the hole. Make sure the top of the plant's root crown is level with or slightly above surrounding soil. Avoid poorly drained areas or places where water frequently collects. Planting too deep or too shallow are common problems. Deep planting favors root and crown diseases. Planting too shallow leads to root damage from exposure and excessive drying.

Remove the container, cut any wires or rope around the root ball, and place the plant in the hole and position the main stem perpendicular to the ground. Check for roots that circle the container and gently spread them. Cut any broken or encircling roots. Do not use the plant if it is extensively rootbound. Backfill the hole after properly positioning the plant and preparing the roots. Do not cover the container soil with field soil, as the difference in texture can prevent water from penetrating into the container soil around the roots. Settle the soil after planting by watering. Keep a four foot diameter or larger area around the trunk free of turf or other vegetation.

Remove any trunk wrapping that came with the new plant, as it may restrict trunk growth. In extreme situations only, prevent sunscald by applying white interior or exterior latex paint (without a solvent base), diluted 50% with water, to the trunk.
