With the exception of geraniums, these plants are not likely to need any more water than those in other locations of the house. Some flowering begonias will do well in west windows because they tolerate brighter light. It will be helpful if they can be lightly screened from direct sun, such as with lace curtains. Jade also will tolerate relatively low light, but this plant is a succulent and seems to thrive in most locations. It might, however, sunburn in an extreme south exposure.
African violets are best in an east exposure.
They usually do well, but during the winter, they may need supplemental light. They may not flower without longer days. Usually houseplants are overwatered or watered too little, too often. Water houseplants thoroughly so soil is saturated. To avoid buildup of soluble salts, discard water that accumulates in drip pans.
