Only fertilize the succulent during the growth period. This is the spring and the summer. The first bloom takes place in early spring and the second happens in the fall. You can water your Crassula Perforata once per month in winter, every 7-10 days in summer and every 10-14 days through spring and fall, depending on the weather. Depending on the intensity of sunlight the plant receives, the leaves can develop a deep purple to pink outline. The leaves grow on the stem-like tightly stacked rosettes and depending on the amount of sunlight, the leaves develop a pink tint at the edges.
