buds don't bloom #877195

Asked July 14, 2024, 6:54 PM EDT

This green tree has a lot of buds every year, however the buds don't bloom. 2 years ago I got all the branches trimmed, however it is still the same. The buds eventually show a brownish color and don't bloom. This year am trying to give more water (about 10 minutes). What could be the reason? Thank you

Your tree is a Rose of Sharon. They are pretty tough, easy care plants.
There are multiple reasons that they may not bloom, most commonly if they are getting too much shade (full sun?), too much water (can cause rot) or if they are not getting enough water. 
The last couple of years have had extended periods of drought and heat, which can cause flowers to abort.
The soil should be moist but well-draining.
It is a good sign that you have all those buds 
and we are hopeful with good watering technique you will get some to bloom this year.
The first thing we suggest that you do is related to mulch- make sure that your mulch is no deeper than 3 inches, and keep it pulled back from contact with the trunks of the tree.
Ten minutes of watering is probably not enough in the weather.
Here is our watering information:
https://extension.umd.edu/resource/watering-trees-and-shrubs/
Watering is best done slowly and deeply and moved all around the tree, so put your hose on a trickle, lay it a foot or two from the trunk, leave it for a while, and then move it to another area.

After watering, follow the instructions in our link to use a screwdriver and your finger to feel the soil to be sure that the water is getting to the root area where you think it is.

It's possible that you could have a tiny insect called thrips within the buds, but less likely.
