Light

This tree needs full sun.

A partially sunny or shaded location reduces the number of flowers.

If it is in a sunny spot, your tree will explode with huge white clusters of blooms.

The ideal soil is average, rich in organic material, well-draining, and neutral to slightly alkaline.

Water

Ivory silk lilac is somewhat drought tolerant.

However, in extremely dry weather, the tree appreciates supplemental water.

Water a newly planted tree weekly at a rate of a gallon per trunk diameter at chest height.

Maintenance pruning rejuvenates the tree and encourages new growth.

Trim away 1/3 of your trees largest stems.

Common Pests and Plant Diseases

The ivory silk lilac is not bothered by many insects.

Borers may annoy the tree but it is not a serious problem.

However excessive boring into the branches may weaken them and they will break off.

Prevent infestation by keeping your tree stress-free with water and regular fertilizing in overly dry weather.

If borers attack, remove the infested, damaged branches and dispose of them responsibly.

Verticillium wilt is a concern, but proper fertilizing andproper tool sanitationare the best ways to avoid this problem.

The bloom period is short, however, lasting a couple of weeks.

Wilting Flowers

Leaf Drop

Defoliation may occur on ivory silk lilac trees planted in too much shade.

The trees may be afflicted by powdery mildew, which can cause leaf drop.

Leaves will turn black and die.

Wet weather causes this problem.

Thin out extra shoots in the tree to give the plant air circulation.

Control the plant’s height by trimming it after the flowers bloom.
