How To Care For My Hydrangea Tree. Feed the hydrangea tree twice a year. Most varieties thrive in full sun to part shade as long as they are planted in moist rich soil.
Deeply water 3 times a week to encourage root growth. Protect your hydrangeas from cold winds by planting them in a sheltered spot or with a burlap windscreen or burlap frame filled with dry leaves. The best way to do this is to use hydrangea water that contains either organic or synthetic substances to make sure the water is all clean and safe for your hydrangea.
The best time to fertilize is in early spring just before the plant produces new growth so plan on feeding the tree immediately after the spring pruning.
Just pick up some decorative pots and nursery-grown hydrangeas in containers from your local garden center to get started. Water the hydrangea frequently so that the soil is moist but not saturated hydrangeas require soil that is moist yet well draining so that the roots do not sit in boggy soil and rot. Gently loosen the roots then plant using plenty of rich soil. Feed the hydrangea tree twice a year.
