I just planted my lilac bushes and the leaves are curling and turning brown does anyone know why.?

Answer 1

First, make sure your lilacs are in soil with good drainage.
Q."I just looked at a row of young lilacs with leaves that are turning brown and dying. I know there was a lot of standing water near them for some time, but apparently they were not actually standing in water. I dug up some soil and found it’s still very saturated..." A. "Lilacs are tough, but they don't tolerate standing water very well." Too much water in the root zone may manifest these symptoms & can also led to a borer attack. (1) (Good Question & answer site on Lilacs)

I'd be careful & use sanitary precautions, just in case it is bacterial blight, which is common. Prune diseased twigs below twigs & leaves, when the bushes are dry (don't touch wet leaves). Disinfect shears each time with 10% bleach or alcohol after each cut. (2)

Or... it could be Powdery mildew: "Leaf curling and twisting may be noted before the fungus is evident. Severe powdery mildew infection will result in yellowed leaves, dried and brown leaves and disfigured shoots and flowers." (3)

Discard the damaged leaves & as a precaution against Powdery Mildew, try a milk/ water solution. "Milk works in two ways: It has a germicidal effect--it kills the fungal spores-- and it also appears to stimulate plants in such a way that they become more resistant to the disease. In recent university tests, the milk and water spray was found to be more effective than the two most popular synthetic fungicides on the market today."
Mix 1 cup of milk with 9 cups of water.
Spray the entire plant twice a week. (4)

Answer 3

check the curled leaves for bugs. if so soapy water sprayed on the plant will help. sometimes they go into because of being just planted.

Answer 4

That's transplant shock. Give them a good drink of Root Stimulator (Fertilome makes a good product) or MiracleGro. They'll want extra attention until they're established (new leaf growth = root growth)

good luck
