I have some lilacs which bloom every year; some others, in different locations, that have never bloomed in ten years. I have added bone meal without success; what can I do?
LilacsHi Ed, Here are the 7 most common reasons why your lilac is not blooming.
Posted by Diane from RI on 2009-09-04 10:46:00
Reason #1: It's Not Getting Enough Sun
to thrive and flower, lilacs need a MINIMUM of 6 hours of sun a day.
Reason #2: It's Too Young
Most Lilacs will not bloom until they reach 3-6 years old.
Reason #3: It's Over Fed
if your soil is nutrient-rich, you only have to feed once a year.
Reason #4: It's In Shock
Lilacs need a fairly long period to settle in
Reason #5: It's Dry
Keep your lilac on a regular watering schedule and adjust it for heavy rain or extended periods of drought.
Reason #6: You're Improperly Pruning
Pruning should be done immediately after flowers die off.
Reason #7 : Your Soil's Imbalanced
Lilacs prefer a soil pH from 6 to 7 (a little on the alkaline side).
Ed, If none of these reasons can be applied to your situation, consider giving your bush a light root pruning in early summer. Jam a sharp spade into the ground on two sides of the plant about 12 inches out from the trunk. And maybe next year will be the year!
Good Luck Ed and please let me know how you make out!
