Caring Tips For Potted Hydrangea Plants
The colourful huge blooms of the hydrangea make them a perennial favourite in gardens as well as for patios and sun rooms. While some people choose to transplant hydrangeas from pots into the soil, the plants are hardy enough to survive in potted containers. The key to healthy potted hydrangeas lies in their care. Here are several tips to care potted hydrangea plants. Place your potted hydrangea plant in a bright location that receives indirect sunlight during the spring months. Move your plant at night to a location with a temperature of 10.0 to 15.5 degrees C, as hydrangeas prefer cool nighttime temperatures. Water your plant to keep the soil moist. Water indoors by placing the hydrangea pot in a tray of water for approximately 45 minutes to soak the water through the bottom of the pot. Remove the pot from the tray immediately after the soil has become wet. Plant your potted hydrangea outdoors once there is no longer a risk of frost. Plant the hydrangea in a soil that is nutrient-rich and retains moisture. The planting location should be semi-shaded to prevent overexposure to the sun.
Fertilise your plant every two weeks with a complete liquid fertiliser when the growing season begins in May. Stop fertilising in the fall season when the plant growth slows down. Remove extra shoots from your potted hydrangea to increase the flower head size. Cut to remove the plant’s centre, main shoots so there are only three developing on the entire plant. Cut the hydrangea shoots so that there are two pairs of leaves left on the each shoot once the flowering is complete. Pinch back long stem growth by removing several inches of new growth that develops in the month of June.
