Fertilize citrus trees in the spring and summer. The ability of a citrus tree to use nutrients in fertilizer depends largely on whether or not it is growing in the proper soil. Citrus trees most often need nitrogen, although they may also be deficient in minor nutrients.
The key to success with heavy-feeding hibiscus plants is to fertilize lightly and often. Hibiscus should be fertilized at least once a month throughout the growing season, and the schedule should be kept up regularly. Remember that numerous light applications of hibiscus fertilizer are always better than a few heavy applications. See chart for feeding amounts.
