If you are growing a Hydrangea, aside from the climbing varieties, you will find that they are moderately slow growers. However, they will still need help from time to time, especially if they are younger.

Regular Varieties

If your Hydrangea is starting to reach the point where it’s flopping over, you might need to give it some support while it is continuing to grow. Almost all of the big leaf and panicle varieties get significantly sturdier as they establish themselves and become free-standing mature plants, although when they are young you can still give them a hand here or there.

  • Bamboo Canes are mainstay garden stakes of any garden, allotment, kitchen garden or vegetable plot, lending essential support to climbing plants. Used to make simple structures like wigwams or obelisks and crop protection cage frameworks.
  • These canes are ideal for providing strong support for flowers, tomatoes, young trees and other fruit or vegetable plants. Tied together they can form tripods, trellis or other constructions to support runner beans, French beans and peas.
  • These long lasting, versatile bamboo canes are Grade A standard & ideal for any bare root planting, large or small, use in conjuncture with Elixir Gardens spiral tree guards and shelters to keep the plants growing upright and to help keep them protected from Rabbits.
  • We supply our bamboo in a variety of lengths from 2ft to 10ft and ranges from 6mm to 18mm diameter thickness. Please Note: Thickness is guaranteed for the thickest end of the bamboo. The thinner end is usually 70% as thick as the listed size. Our canes are hand cut from sustainably run Bamboo farms. Due to this please allow a tolerance of -/5% in the length of the canes.
  • We also have a huge range of cane caps, wigwam grips, connectors and ties.

If you have one of these varieties you can keep them up right and prevent them from flopping over by giving them stakes to climb against. If you are growing a hedge, for example, one great thing to do is to set up something that is temporary, giving support while they are young, and can be easily removed without damaging the structure once the plants get older. One thing you might want to consider is setting up a stake on either side of your plant, keeping it far enough away that it has room to reach its full size, and running length of steel wire or nylon-like washing line from one end to the other.

This length should be what you temporarily attach the different branches to as the Hydrangea is growing. But once the Hydrangea is strong enough to stand on its own you can easily cut the wire and pull out the stakes without causing any damage to the plant.


Climbers

If you have a climbing variety, these grow much faster and you will need to give them more support to keep them upright and prevent them from flopping over. Climbing varieties will naturally climb but only if they have something to climb up. The best thing to do is grow them near a wall, fence, or trellis that you already have in your garden.

For example, if you have a pergola that rests over a seating area in the back corner of your garden, you might consider growing your Hydrangea up and over that.

  • Please note that wood is a natural product and can show imperfections.

If you don’t have something yet in place you can always build something and then help train the branches up and around the structure you want it to climb. Much the same as the method above, you can even use make-shift items like twine or rope to create the support structure around which the branches will grow but the difference here is that most of the time, climbing Hydrangeas will need that structure to remain in place.

There are plenty of support systems that you can buy in a garden centre that come with stakes, gardening wire or string, and easily removable clips in various sizes. These plastic clips are crafted so that they have a large metallic hoop that goes around the branches, clipping them in place. As they get older (or thicker) and are able to hold themselves up, you can replace the plastic clips with the next size up or remove them as soon as the structure is free-standing.

Most of the time this is a natural part of their growing cycle and they will grow out. As your plant reaches maturity it will be a successful, stand-alone structure that brings you beautiful flowers.
