Hibiscus should NEVER be transplanted under any of these circumstances. After any kind of stressful situation, give hibiscus the safety of their nice, comfortable, familiar pots until the stressful situation is completely gone and the plants have had a few weeks to recover before you consider transplanting.

Hibiscus don't like to ever dry out completely anyway, so if you have a good watering regime, you shouldn't ever have to worry about the soil being too dry to fertilize. During the winter months when your hibiscus are not actively growing and blooming, cut your fertilizer way back. The less active hibiscus are, the less food they need.

Hibiscus can survive temperatures even as high as 115°F (46°C), provided they have adequate water. When the weather is hot, it is best to maintain a steady supply of water to the plant, rather than have it go through wet/dry cycles.

Potted hibiscus in particular can use up most of their water by the end of the day, bringing about a stressed condition to the hibiscus that results in a decrease, or even cessation, of blooms. The way to counter this tendency is to water twice a day, or to transplant the hibiscus to larger pots that hold more water.

Hibiscus prefer a light fertilizing on a frequent schedule, so if you have time to fertilize every time you water, this is the best possible way to keep hibiscus in small pots happy. Use 1/2 the dose on the fertilizer label each time you water, and watch carefully for signs of fertilizer burn - brown edges on otherwise healthy leaves.

To avoid this situation try introducing your new hibiscus to direct sunlight for just an hour the first day, and then increasing the exposure gradually over a week or two. Hibiscus quickly adapt to the amount of light they receive, but moving them quickly from shade to direct sun may result in the white sunburn effect on some of the leaves.

Indoor hibiscus, like outdoor hibiscus, will need a lot of water in hot weather and much less water in cold weather. When you water your hibiscus, water until you see water come out the bottom of the pot into the plant tray, but after 12 hours the water in the plant tray should be gone. If there is still water standing in the tray, pour it away.

The place where hibiscus can stay warm without any extra cost is in your house. Although hibiscus are considered outdoor plants in the United States, in many parts of the world they are very popular houseplants, except for 2-3 months during summer when the pots may be set outdoors. Indoor hibiscus make attractive, green houseplants.

Hibiscus flower colors, like the colors of most flowers and fruits, are made up of three basic pigment groups: carotenoids and two types of flavanoids - anthocyanins and flavonols. While the study of flower pigmentation can be very complex (and confusing!), some fairly simple principles emerge that we can apply to growing our own hibiscus.
