Try to not let the leaves wilt, eve if it means watering twice a day. Wilting will cause the plant's blooms to shut down. You'll notice it stops blooming. That's because it's not getting enough water. I have quite a few hibiscus in pots. We're experiencing temps over 100 each day. I have very few blooms, but they will "pick up" again late Sept. If you only water once a day, water that pot twice. I mean water it, let the water run through while you water something else, then re-water that pot again. The first water will run through and wet the soil. The second watering will catch the roots instead of just running through. Does that make sense?
