Hibiscus should be watered (and fertilized) often during the spring and summer growing season, even more so when they are grown in containers. The tricky part of watering them in containers is avoiding root rot. These plants are native to tropical, swampy areas, so keeping the soil evenly moist at all times is ideal. That said, you don't want the roots to stand with wet feet, so letting the surface soil dry out a bit between watering is typically okay. Any excess water remaining in the planter 30 minutes after watering should be dumped.
Other than keeping the soil consistently moist (not wet), the other thing I would recommend is checking for insect infestations-especially on the tips of shoots, on the buds, and on the undersides of the leaves. Hibiscus can be susceptible to aphids and spider mites. If you don't see any signs of pests, give your plant some time. It sounds like you're doing everything just right.

The leaves on my hibiscus plants are turning yellow. Some of the leaves looks limp like they need water. I have beautiful blooms. Can anyone tell me what to do? I do not want to lose my beautiful plants.

There are a lot of reasons hibiscus leaves turn yellow. Yellow leaves are a signal that the plant is stressed, but the fact that you have beautiful blooms is a good sign. You didn't say whether or not your plant was growing in the garden or indoors. Have any major changes taken place in the plant's environmental conditions recently? Leaves can turn yellow from too much water, not enough water, a lack of light (doubtful if you have flowers), insect damage (specifically mites and thrips), sudden changes in temperature (extended periods of heat or cold drafts from air conditioners), or from having to adjust to a new location (did you move it recently?). Hibiscuses are rather high maintenance plants that don't adapt quickly to changes in their environment. If insects are the problem, treat as necessary. If they are not the problem and none of these other suggestions seem to fit, check the plant for root damage. Otherwise try to maintain stable conditions for the plant and the problem will probably clear up on its own. Avoid continuously changing its food and water regime and keep its light and location consistent.
