Good drainage is essential.
Soil should consist of equal parts of loam and sand with small gravel added to give it the proper porosity. Pay particular attention to make sure that they do not rot at the root from soggy soil. Water when plant is dry and do not water again until the soil is completely dry again. Fertilizer should be applied only once during the growing season, diluted to the recommended rate on the label. During October to March, water very sparingly, using only enough water to keep the foliage from shriveling.
