Wrap Hydrangeas for Insulation The idea is to make your plants think they live in a warmer growing zone. You can use a tomato cage or build a cage with chicken wire/garden fleece/burlap and fill it loosely with leaves. You can even bubble wrap the exterior of this cage, adding even more insulation.

Do I need to cover my hydrangeas for winter?
Whether or not hydrangeas need protection depends on how cold the winter temperatures drop. If the air temperature doesn't go below 0 degrees (zone 7) there is no need for winter protection. In colder climates, wrap or completely cover marginally hardy hydrangeas.
Should I prune my hydrangea in the fall?
Prune these hydrangeas only after bloom in the summer and not in the fall. Old wood hydrangeas start developing their bloom buds for next year in August and September. If you don't prune your hydrangeas real soon, then it is better to wait until next year. Otherwise you won't have any blooms next spring.
When should I cover my hydrangeas?
Other hydrangeas bloom on the current year's growth, but a late-season frost can delay or reduce the number of blooms. If new buds have formed during warm spring weather, you should protect the hydrangeas during an unseasonably late frost to ensure full blooming.
Can hydrangeas survive a freeze?
Some hydrangeas can die because of freezing temperatures and cold winter winds that cause the plant to dry out. Cold weather can pull moisture from stems and leaves, causing dehydration. A late frost in early spring can damage new growth on hydrangeas that bloom on new wood.
Will hydrangeas come back after a freeze?
Yes, many hydrangeas leafed out early this year, then were hit hard by frost that caused damage to leaves and stems. Fortunately, these are tough plants and many types can be cut back to the ground without damage.
What month is considered late winter?
When is Late Winter? Late winter is 4 to 6 weeks before spring thaw begins. This could be any time in January to May, depending on your climate.
Will hydrangeas grow back if cut down?
You can take a more relaxed attitude about pruning if you have hydrangeas that set flower buds on current season wood, like panicle and smooth hydrangeas. ... Even if you cut canes back to ground level during dormancy, the shrubs will grow back and produce blooms in spring.
How can I tell if my hydrangea blooms on old or new wood?
Old wood is quite simply, last year's wood. Hydrangeas that bloom on old wood set their flower buds in late summer on stalks that have been on the plant since the previous year. Hydrangeas that bloom on old wood include the mophead, bigleaf (macrophylla), lacecap and oakleaf varieties.
What month should I prune my hydrangea?
Prune in late winter and early spring. Prune as far back as you want right above the first leaf joints. It will grow from that point onward, getting larger each year. Read more about pruning hydrangeas, and learn whether your shrub blooms on old or new growth in “Pruning Hydrangeas” by Janet Carson.
What do hydrangeas look like in winter?
Hydrangea flower heads turn dry and brown in the fall and will remain that way throughout winter if not removed. Hydrangeas also lose their leaves during fall, but the brown stalks remain upright unless pruned back.
Why is my hydrangea not flowering?
The Bigleaf Hydrangea is the most common victim of the question, “Why Is My Hydrangea Not Flowering?” This is because the bigleaf needs old wood on which to bloom, but the hydrangea frequently suffers from the old wood dying back into the ground during the winter or from its old wood being cut away.
