Hydrangeas make a soft yet powerful statement, as a result of their prosperity of clustered flowers in delicate hues of blue, white, pink or white. Although hydrangeas are commonly grown as shrubs, they develop successfully in containers too. Caring about them in pots needs reasonable maintenance, whether grown inside or out. Always choose hydrangeas that thrive on your region for best growth. As an instance, bigleaf hydrangeas (Hydrangea macrophylla) thrive in U.S. Department of Agriculture plant hardiness zones 6 through 9, whilst oakleaf hydrangeas (Hydrangea quercifolia) perform best in USDA hardiness zones 5b through 9.
Put your potted hydrangeas in places that have morning sunlight and afternoon shade, for best growth.
Add organic matter, such as peat moss, to soil to increase fertility, as potted hydrangeas perform best in potting mix high in organic content.
Fertilize potted hydrangeas with a water soluble fertilizer, such as a 20-20-20, after the instructions printed on the tag.
Irrigate potted hydrangeas often, as these plants need constant water for suitable flower increase and fare badly during drought. Water the plant often enough that roots remain moist without keeping moist soil, which may lead to disease problems. Irrigate when the upper layer of dirt or potting mix feels dry to the touch. Check soil more than once on a daily basis until you are acquainted with how often your plant needs water.
Prune hydrangeas with shears after flowering. Remove faded blossoms to encourage new growth.
