Title: Mountain laurel (Sophora secundiflora) refuses to bloom
Answered by: Nan Hampton
QUESTION:
We have a Texas Mountain Laurel that gets full sunlight, but does not bloom. It is 4-5 ft tall & 3-4 ft wide & healthy. Is there anything we can do to make it bloom next year?ANSWER:
It sounds like everything should be ideal for your Sophora secundiflora (Texas mountain-laurel) to bloom. However, Mr. SP has one question? Are you fertilizing it? If you are, don't do it! Here is a quote from a previous question about native plants failing to bloom:
"The problem with flowering shrubs that are not flowering, native or not, is often too little sunshine or too much lawn fertilizer. Obviously, if you have it in full sun in Austin, that is not the problem. Lawn fertilizer, which possibly is being spread a little farther than the lawn, is high in nitrogen for green leaves (or blades) of grass. A plant you wish to flower but give too much nitrogen will get lazy and fail to bloom. A plant has just one goal in life and that is to reproduce itself. To make seed, it must make flowers, but if it doesn't feel just a little bit insecure about its future, it won't expend the considerable energy to create the flowers."
In general, native plants do not need to be fertilized—one of the many advantages for planting native.
