Water sparingly. Like most succulents, the jade plant likes its soil to become dry in between watering. They store water in their fleshy round leaves. Too much water is one of the most common problems with jade plants not thriving. Landscapeplanet.com recommends watering jades at most twice a month during the hot summer months and only once a month during the rest of the year.
Choose coarse, sandy soils for the jade to thrive. A gardening soil with large amounts of clay, silt and sand is best. The jade plant should receive plenty of sunshine throughout the day like most plants in the succulent family.
Prune the plant when it gets top heavy. Trim the stems and prune the leaves. Do not water it after pruning, this will cause the roots to grow in search of moisture and this will prevent it from getting top heavy again.
Re-pot the plant when it needs it. One size bigger than the previous pot is all that is necessary to help this plant to thrive.
Treat with triadimefon or thiophanate methyl if the plant has scabs on the leaves. This is a sign of powdery mildew and the treatment will effectively rid the plant of this disease.
