How far apart is a good measure to plant Climbing Hydrangea for covering a masonry wall?

Question

wall is the length of 17 feet and have 10 hydrangea vines (4" cup size).

also for anyone with experience/ knowledge of this vines growth habits.......how long will it take roughly to establish itself well and grow vertically the heigth of 5 feet?

and how does it look in the winter time and how far from the wall does it bush out?

Thanks for your answers!

Answer 1

Plant them 3' apart.  They love water. Should reach 5' in 3 years and about 2' wide. They need to be planted in shade, north side of your house.  We have had ours 4 years and they have not bloomed we were told this year to apply triple phosphate in the fall.

Answer 2

Hydrangea petiolaris grows up walls without support and despite adventitious roots { on stems } does not damage masonry.

Planting distance is about 6 ft apart at the very least ------ 10 plants is far too many.  5 plants is plenty.

Fairly slow growing and will outlive Methusalah it would take 2 seasons to reach 5 ft.

In the wintertime the gnarled stems look all twisty and aged and it extends from the wall about 1 ft only.

Birds love to nest in the twisty branches.

Good choice ---dont plant too close.
