When do redbuds flower?
I planted a couple of redbud trees several years ago and they are growing nicely. But they have never produced any flowers. They just leaf out each spring. Do the trees have to be a certain age before they flower? I think it's been at least 7 years since they were planted and the trees are taller than I am.
In general, redbuds flower at a young age about 3 to 6 years.
They grow best in a well drained soil in full sun to light shade. They are considered an understory tree. The tree does not like any type of stress such as a permanently wet site, lack of water, too much moisture, mechanical injury, etc.
If you are fertilizing with too much nitrogen, there will be foliage at the expense of flowering.
