Tips for Care:

Lilacs are easy-care and cold resistance and Heirloom Congo Lilac has it all! It also loves the full sun! Not particular on soil type, any rich well-drained soil is best, preferring slightly alkaline soils. Amend with compost and add organic, slow-release blooming shrub fertilizer in spring. Be sure Lilac does not sit in water, nor dry out for too long to protect your investment.

A generous layer of mulch helps retain soil moisture as well as insulate the root system from heat and chill. Water well through the crucial establishment period and during extended drought. Be sure to not cluster Lilac too tightly among other large trees or shrubs.

If you live with deer in your area, apply repellent spray on planting day. Deer are hungry and curious, and you want to train them to leave your plants alone. Reapply according to the label.
