Succulent garden design is appropriate for warm, temperate, and even cold season locations. It is not always possible in cold climates to have a succulent garden outside, but you can grow them indoors in containers.
Learn a little about how to plan a succulent outdoor garden and bring some fun shapes and textures to your landscape.
Succulents are generally drought-tolerant plants that have thick leaves where they store moisture. Although they are very tolerant of dry conditions, succulents need water, especially during the growing season.
Succulent garden design should consider the location, soil type, configuration, moisture level, and plant types. Some succulents are more drought tolerant than others. Do a little research on the wide variety of succulent shapes and sizes before starting a succulent garden outside.
For instance, cacti are succulents and hold water in their stems and pads. Other succulents are not spiny but have swollen leaves with a myriad of growth habits. There are spreading or drooping types, such as Sedum morganianum, wide spiky plants like Agave, or tall, columned varieties such as Cephalocereus senilis. Plan the design with enough space for the plants to fill in as they grow.
Growing a succulent garden outside starts with plant choices. If you are a novice, begin with plants that are easy and foolproof. Sedum and Sempervivum are easy to grow and adaptable to bright, sunny locations or even slightly dappled areas.
Whatever types of plants you choose, succulents need well-drained soil. They can thrive in cracks and crevasses, rockeries, and sandy or gritty soils. Succulents in cool-season areas will do best in containers that can be brought indoors for the winter.
Try some Kalanchoe, Aloe, Echeveria, and Aeonium. Have fun with the unique sizes, shapes, and textures of these plants. Use succulent outdoors as part of the garden's xeriscape area to conserve water and provide interest and color.
Planning Your Garden
When you have chosen your plants and are ready for planting, you will need to know how to plan a succulent outdoor garden. Choose a sunny location and plot the space you want to fill.
Check the soil conditions and drainage by digging a hole at least 1 foot (30 cm) deep and filling it with water. If the water drains within a half-hour, the soil is sufficiently porous. If not, mix in 3 inches (7.5 cm) of sand or other gritty material to increase the texture and drainage.
Use taller specimens at the center of the area and spreading species at the edges or dotted among the larger plants as ground cover.
Top the area with a layer of pebbles or small rocks to act as mulch. This will help prevent weeds and conserves moisture while allowing the evaporation of excess water.
Succulents tolerate periods of dryness but should receive regular water during the growing season. When soil is dry a couple of inches down, water deeply and then let the soil dry out again between waterings.
The most common problem with succulents is rot. Keeping the stems out of the soil and providing drying periods between irrigation will help prevent this. Water from the plant's base to keep leaves dry.
Watch for insect pests and combat them with sprays of water and horticultural soap spray.
Remove dead stems and offsets during the care of succulent garden plants. Offsets are easy to start as a completely new plant. Put them in a well-drained potting mix and care for them until roots are full and healthy, then plant them in a new area of the garden.
