The best time to fertilize this succulent is during the growing season. The first flowers appear in spring and the second occur in fall. Your Crassula Perforata can be watered depending on the season. It can be watered every 7-10days in the summer, every 10-14days during spring and autumn, and once a month in the winter. Depending on the intensity of sunlight the plant receives, the leaves can develop a deep purple to pink outline. The stem-like, tightly stacked rosettes form the leaves. The amount of sunlight can affect the pink color at the edges.
