The following are a few tips to help keep your hydrangea happy and healthy: · These hearty flowers can be planted in full sun or partial shade.
· They do not easily succumb to insects and diseases.
· They prefer rich, moist soil, so water weekly.
· They need to have some shelter from very high winds, as their leaves lose moisture easily and then wilt.
· After the flowers bloom they need to be pruned.
· Fertilize in the early spring for best results, using a granular fertilizer.
· Pruning can be safely done in late summer.
Buds can still form after that time, which will give you your spring flowers.
If you prune too late in the season, you may be destroying those blossoms.
