When can you plant hydrangeas in Zone 5?
Planting Time
Although hydrangeas may be planted in the spring, the best time to plant a nursery start is in the fall after the plant has stopped blooming and before it goes dormant for the winter. A hydrangea has lots of feeder roots near the surface, so the root ball should have lots of roots.
What are the hardiest hydrangeas?
Most hydrangeas prefer only morning sun. Yet one type of hydrangea can soak up the sun all day: the panicle hydrangea. While they can stand the sun, these do just fine in partial shade, too. Plus, panicle hydrangeas are the hardiest hydrangeas.
How do you winterize hydrangeas in Zone 5?
A good way to start winterizing hydrangeas is to lay down a thick layer of mulch over their root area. Straw works well for this. For even greater protection, cover the shrub with a wire cage, or build a cage around it with strong stakes and chicken wire. Wrap burlap or insulation cloth around the cage.

What side of the house do you plant hydrangeas?
It's recommended to plant Hydrangeas on the side of the house that receives adequate light and coolness. Prepare the soil at the left side if much sunlight comes through that side of the house for Hydrangeas. And it's not only hydrangeas that can live beside the house, other plants can as well.
What can you plant next to hydrangeas?
Other shade-loving plants such as ferns, astilbe, heuchera and Solomon's seal will also grow well in the shade under or near the outer edge of hydrangeas. Their more delicate leaf structure will provide a nice contrast to the broader hydrangea leaves.
Do Hydrangeas like coffee grounds?
If you're growing hydrangeas, use coffee grounds to affect their color. Coffee grounds add extra acidity to the soil around hydrangeas. ... Seedlings thrive off the nitrogen content in coffee, so give them a boost by making a natural fertilizer from the grounds.
Are hydrangeas high maintenance?
Growing hydrangeas really isn't too demanding. Once you get the plants settled in the right spot, these are low-maintenance plants that bring on the floral fireworks with little ongoing care. Hydrangea maintenance depends in part on where you garden. ... While plants are still dormant, tackle transplanting hydrangeas.
Should hydrangeas be cut back for winter?
1. To get bigger flowers, cut them all the way back. In late winter or early spring, these shrubs can be cut all the way back to the ground. Smooth hydrangeas will produce much larger blooms if pruned hard like this each year, but many gardeners opt for smaller blooms on sturdier stems.
How cold is too cold for hydrangeas?
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.
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.
