Bougainvillea wilting/dropping leaves
I'm in Dallas, zone 8A, and have a large potted bougainvillea that sits out on our pool deck. It gets full sun probably 8 hours a day.
It didn't start to bloom until a few weeks ago. Before that time, the leaves were just fine. They weren't falling off and the plant never wilted.
Before it started blooming, I didn't really water my boug all that much.
Now, it seems like it needs water every day. The temps have been in the low-to-mid 90's here in Dallas over the past couple of weeks. I have been watering it when the leaves start to wilt.
They now wilt mid afternoon and I do notice that it is shedding some of its leaves.
When I probe the soil using a Rapitest moisture meter (range 1-4, 1 approaching complete dry, 4+ is wet), it says that the soil is a 3. Down near the bottom of the pot, it's at 4 (wet).
Am I overwatering this plant?
I have a feeling I'm giving my boug too much attention.
Should the the soil be "dry" all the way down before I water it again?
If I cam overwatering this, what I can I do to restore this quickly so I don't have a wilting plant sitting in my backyard for weeks...
Sorry for the long post.
