Culture Notes
Weigela grows best in a sunny location and moist soil.  Shaded plants are straggly.  Weigela also dislikes crowding.  The growth rate is moderate and the shrub transplants well, reaching a mature height and spread of only 2 to 4 feet.  Some annual dieback and winter injury make annual pruning necessary. It is best to perform any needed pruning immediately after they have flowered. Canadian cultivars (the so called Dance cultivars) are the most cold hardy. Plants suffer in the deep south eastern part of the US. This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Planting and establishing shrubs

The most common cause of young plant failure is planting too deep.  Plant the root ball no deeper than it was in the nursery.  In most instances, the root flare zone (point where the top-most root in the root ball originates from the trunk) should be located just above the landscape soil surface. Sometimes plants come from the nursery with soil over the root flare. If there is soil over this area, scrape it off.  The planting hole should be at least twice the width of the root ball, preferably wider.  In all but exceptional circumstances where the soil is very poor, there is no need to incorporate anything into the backfill soil except the loosened soil that came out of the planting hole.  Never place ANY soil over the root ball. If a row or grouping of plants is to be installed, excavating or loosening the soil in the entire bed and incorporating organic matter enhances root growth and establishment rate.

Weed suppression during establishment is essential.  Apply a 3-inch thick layer of mulch around the plant to help control weed growth.  Keep it at least 10 inches from the trunk.  If you apply it over the root ball, apply only a one or two inch layer.   This allows rainwater and air to easily enter the root ball and keeps the trunk dry.  Placing mulch against the trunk or applying too thick a layer above the root ball can kill the plant by oxygen starvation, death of bark, stem and root diseases, prevention of hardening off for winter, vole and other rodent damage to the trunk, keeping soil too wet, or repelling water.  Regular irrigation through the first growing season after planting encourages rapid root growth, which is essential for quick plant establishment.

This plant has attractive foliage and attractive fall colors.

Culture Notes
Japanese Barberry is thorny, so it's useful for barrier plantings.  The plant tolerates most light exposures and soils, but purple-leafed cultivars turn green in shade.  This shrub grows slowly but transplants easily.   Japanese Barberry can be sheared and used as a hedge plant.

The main ornamental features are persistent red fruits and fall color in shades of red, orange and yellow. This cultivar is a form of the variety atropurpurea and is more compact than many other cultivars. This plant is considered mostly allergy free and causes little or no allergy problems in most people.
