Question: – I have a white lilac bush about three years old which has big healthy leaves, but it has never had a flower on it. Could you tell me what is wrong with it? O.S., Kentucky.
Answer: – If the lilac is growing nicely probably there is nothing wrong. Sometimes it takes more than three years for a lilac to become established and come into bloom. Then there is the question of sunlight. The less sunshine the fewer the flowers. Again, severe summer growing conditions such as drought coupled with excessive heat may prevent formation of flower buds. Finally, fall pruning if practiced will ruin any chance of spring bloom.
