Hydrangea 'PeeWee' problems — and how to fix them
Hydrangea 'PeeWee' (Hydrangea quercifolia 'PeeWee') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Loss of next year's blooms
It flowers on old wood; pruning in autumn, winter, or spring removes flower buds. Prune only immediately after flowering in summer.
Root rot in wet soil
Oakleaf hydrangeas are very sensitive to poor drainage. Plant on free-draining ground or raised beds and never let roots sit in water.
Winter bud dieback
Old-wood buds can be killed by hard late frosts at the cold edge of its range. Shelter from harsh wind and mulch the root zone.
Leaf blight
Fungal spotting in humid, crowded sites. Space plants for airflow, water at the base, and remove fallen leaves.
