You could also consider shorter grass-like plants. Whatever you choose, make sure it’s something that will thrive in shady conditions, as that’s what oakleaf hydrangeas need.
What do oakleaf hydrangeas look like in winter?
Oakleaf hydrangeas are one of the most beautiful shrubs in the winter garden. The bark peels back, revealing the dark layer beneath, and the leaves take on shades of red and orange. The flowers are gone, but the plant is still an important part of the winter landscape.
What month is best to plant hydrangeas species?
Fall is considered to be the best season to plant hydrangeas, as they are deciduous plants and will lose their leaves in winter. This means they won’t have to expend energy growing leaves in the early spring when it’s still cold and can put that energy into growing roots.
If you live in a colder climate, you may also want to wait until late spring or early summer to plant them, so they have a chance to get established before the first frost.
What happens to hydrangeas plants if you grow them too close together?ro
If you decide to plant hydrangeas too close together, the separate plants will touch sooner and then overlap at maturity. To avoid this, keep a distance of at least 2-3 feet between each plant. Also, make sure to choose a location with plenty of space for the plants to spread out as they grow.
