Hydrangeas are large, flowering bushes popular in home landscaping and flower gardens. The flowers grow in bunches and bloom in blues, pinks, whites and purples through the summer. Hydrangeas are hardy plants, and grow easily from cuttings.
According to HydrangeasHydrangeas.com, choosing the right location can mean the difference between thriving hydrangeas and failing plants. The bushes need morning sun and afternoon shade, with a preference to slightly sunnier locations for full blooming.
Hydrangeas do best with loose, rich and very fertilize soil, with plenty of organic compost mixed in. Fertilize the plants in May or June with a dose of balanced fertilizer, and feed them again in August.
According to Ruby Glen, hydrangeas need plenty of water if they're to thrive. Give them 3 inches of water a week in rich soils to keep the moisture content up. Restrict these waterings if hydrangeas are planted in clay soil, as it won't drain as quickly and may cause root rot.
The best way to propagate hydrangeas and grow new, young plants is through cuttings of the original plants. Take 5- to 6-inch cuttings from the branch of a healthy, established hydrangea, trim the leaves off the bottom of the stem and dip it in rooting hormone. Place the stem in a pot with quick-draining soil for rooting.
New cuttings of hydrangeas do best in shade rather than bright sun, which might burn them. They will root in two to three weeks, and are ready to transplant outdoors into the garden at that time. The best time to transplant new hydrangeas is in the spring, after the spring thaw.
