Succulents are popular for two simple reasons: they are beautiful and nearly indestructible. They have shallow roots that form a dense mat just under the soil surface. With thick, fleshy, water-storing foliage, stems and/or roots, they are especially adept at surviving harsh Arizona conditions.
A fascinating variety of exciting succulent foliage and plant shapes abound, including paddle leaves, tight rosettes, bushy fullness or trailing columns of teardrop leaves. Aloe and agaves are the most well-known of the smooth-textured succulents, while cacti comprise a unique prickly subset of the succulent family.
Succulents make excellent display plants in rock, dish or container gardens. No matter what kind of succulent you are growing, the rules are pretty similar among the different species. Here are the guidelines for growing eye-catching, thriving succulents.
Succulents prefer bright light, like that from south-facing windows or outside walls. Unhappy plants that are under-lit begin to stretch, resulting in elongated stems and widely spaced leaves. This condition is known as etiolation. The solution is to prune the plant back to its original shape and provide it with better light.
Temperatures for Growing Succulents
Succulents thrive in the desert’s extreme day-to-night temperature swings. With the numerous cold-tolerant varieties available, and so many tropical varieties being introduced, be sure to ask a garden expert for the best succulents to grow outdoors. There are many kinds of succulents that thrive outside in our summer heat.
Especially in the heat of summer, succulent plants should be watered generously. Allow soil to dry to nearly alarming levels before giving them a deep soak. Once per week irrigation is ideal, even during hottest spells of the year. Succulent irrigation during winter should be cut back to once every other month. Overwatering and its ensuing plant rot are the most common causes of succulent failure!
Too Much is Not Good
Succulents should never be allowed to sit in water. Overwatered plants will appear soft and discolored; the leaves may be yellow or white and lose their natural color. A plant in this condition is beyond repair. Remove it from its pot to inspect the roots. If roots are brown and rotted, cut away dead tissue and repot the pruned plant into drier potting soil. It often is better to take a cutting, discard the water-damaged plant, and propagate a new plant.
Succulents should be potted in a fast-draining mixture that’s specifically designed for cacti and succulents. If you don’t have access to a specialized mix, like Watters Organic Potting Soil, consider modifying a standard potting mix with an inorganic agent like perlite to increase aeration and drainage.
With dozens of varieties of succulents available, have fun choosing different colors and textures to plant together. It’s even okay to add cacti to spice up a garden of succulents!
During the summer growing season, feed plants with Watters Flower Power 52, just as other houseplants and outdoor container gardens are treated.
