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.
The Spruce / Evgeniya Vlasova
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.

Prune annually while the tree is dormant and before new growth appears.
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.
