How to Grow New Hampshire State Flower

The perfect location is a spot that receives full, bright, but indirect sunlight for at least 4-5 hours daily. Too much shade can cause delayed or no blooming.
Also, avoid growing it in a spot that gets exposed to the harsh afternoon sun for long hours.


Water the plant whenever the top 2-4 inches of the soil feels dry to the touch. Usually, 1-2 times every 7-10 days is good.
Do not water the plant daily and avoid letting the soil go dry completely.


After the Purple Lilac has bloomed in the spring, feed the plant with a balanced liquid fertilizer, once in 1-2 months. Follow the directions mentioned on the label. 
You can skip feeding it altogether once it grows to about 4-5 feet. 


Prune the plant regularly to maintain the desired shape and size. It will also help in preventing diseases like powdery mildew

Pests and Diseases
