It’s better to leave the flower heads on hydrangeas over winter. Lacecap hydrangeas are hardier than mophead types and can be deadheaded after flowering, but it would be best to do this no later than August, cutting back to just above a pair of leaves.Hydrangeas that bloom on new wood can be safely pruned in late fall once the plants have gone dormant or in early spring. Next year’s flower buds won’t be formed until late spring the same year they bloom, so there is no risk of removing the buds if you prune in fall or spring.Hydrangeas flower from mid- to late summer on the previous year’s growth. Mophead and lacecap hydrangeas will bloom satisfactorily with little attention, but annual pruning encourages new, vigorous growth and a better flowering display. Likewise, other species, including climbing hydrangeas, will benefit from a trim.Hydrangea flowers can wilt due to too much sun or insufficient watering.

How big do quercifolia hydrangeas get?
Hydrangea quercifolia, commonly called oakleaf hydrangea, is an upright, broad-rounded, suckering, multi-stemmed, deciduous shrub that typically grows 4-6′ (less frequently to 8′) tall. We recommend feeding Hydrangea with a slow-release, granular fertilizer such as Plant-tone® + Iron-tone® OR Holly-tone® + Iron-tone® in both spring and midsummer. For a bloom boost, try applying Triple Phosphate, per package instructions, in addition to fertilizer.If your oakleaf hydrangea has grown too big for your liking, or is becoming too woody, cut it right back. Make cuts at the base of each branch where it meets the main stalk – making sure you step back to keep an eye on the overall shape and prune from all sides to keep it balanced.You’ll need to plant it in a cutting-friendly, well-draining mix made specifically for seed starting, which usually includes materials like coir, sand, or peat moss. Make holes about two to three inches deep, and plant the hydrangea cutting into the soil right to the edge of the bottom set of leaves.Mountain Hydrangeas Like bigleaf hydrangeas, leave your mountain hydrangea’s (hydrangea serrata) blooms on the plant until spring. Doing this will help protect young shoots and buds.The best fertilizer for hydrangeas is a balanced, slow-release fertilizer with an NPK ratio of 10-10-10 or similar. Specialty fertilizers formulated for flowering shrubs or specifically for hydrangeas often include micronutrients that promote healthy growth and blooming.
What are the benefits of hydrangeas Quercifolia?

Likes full or partial sun. Provide a thick layer of mulch over the root zone to help retain soil moisture. Protect young flower buds with a winter wrap in the lower range of its USDA zones 5 and 6.Hydrangeas that bloom on new wood can be safely pruned in late fall once the plants have gone dormant or in early spring. Next year’s flower buds won’t be formed until late spring the same year they bloom, so there is no risk of removing the buds if you prune in fall or spring.Hydrangeas do best when they can have a period of dormancy, brought on by freezing weather. Except in a greenhouse, hydrangeas, indoors, draw insects, lose their leaves and seldom set bloom. They tend to dry out quickly and wilt, causing them to lose their vigor.
