All of the climbing hydrangeas have one thing in common:  it takes them a while to establish their roots after they have been planted which means that if you decide to plant evergreen climbing hydrangeas, you probably won’t see much happening the first year after you have planted it. But of course you will have to keep that soil moist and continue watering day in and day out even if you don’t see any changes to the plant.

What climbing hydrangeas including this Evergreen variety have in common with all of its close relatives is that once the plant starts growing, it doesn’t stop.

It can make quite a bit of difference, especially in those first few years. This unique Evergreen Climbing Hydrangea like any Climbing Hydrangea is really something that you need to add into your home for the long-term.

  1. Can you plant this in clay soil mine is quite bad or should I put in pots ?

  2. Hydrangea seemanii are happy in clay soil as long as it’s in shade. It’s essential to water (but don’t soak) the plant daily when you first plant it, until it becomes established. You definitely don’t want the roots to dry out at this stage, but the clay soil should help with this. It might look like nothing is happening in the first year, but it should grow steadily in the following years. Trim any flowers as soon as they appear to aid growth, but only in the first couple of years. Seemanii is far happier in the ground rather than a pot.
