Sedum plants offer hardiness and drought tolerance. Sedum's succulent foliage easily stores water to sustain the plant in the hot, dry summer months. Sedums grow quickly and produce abundant blooms in shades of yellow, pink, red, orange and white. Sizes range from 1 to 3 feet but a few varieties offer dwarf sizes that measure only a few inches. Currently there are over 500 varieties of sedums available. Sedums grow well in USDA zones 3 to 9.
Sedum plants prefer full sunlight but will tolerate partial shade. Sedum varieties that grow tall often flop over when they do not receive ample sunlight. Avoid planting taller sedum in partial shade. If the plant flops over due to poor sunlight, trim it back by half in July to encourage the plant to bush out more.
Sedums thrive in poor soil conditions. They do not grow well in soil that contains abundant organic matter. Sedums prefers sandy or rocky soil and will often thrive where very few other plants will live. Soil that retains too much moisture causes the root system of the sedum to rot and the plant will die. Adding gravel or sand to the soil at the time of planting will help assure that the sedum has adequate drainage.
Sedum plants require very little water since they grow best in locations that are dry. Over-watering will quickly kill the sedum. Water sedum only if the rainfall is less then 1 inch per week. Applying 2 inches of mulch around the base of the plants will help the soil retain moisture in hot summer temperatures. Add 1 to 2 inches of aged manure when planting in the spring to help fertilize the newly planted sedum.
The leaves of the sedum plant are succulent in nature and retain abundant water during times of drought. Often the leaves break away from the plant and fall to the ground. When the leaves are allowed to lay on the ground they quickly root. Dig up the tiny plants that occur from the leaves and transplant to new garden locations.
Trim the dead and dying foliage of the sedum plant back in the fall and apply 2 more inches of mulch to the soil surrounding the plant to prepare it for winter. The sedum can withstand temperatures down to -30 degrees Fahrenheit once established.
