If you have a climbing hydrangea that you love, why not make more of them? What are the most rewarding aspects to successfully cultivating flowers and plants in your garden is that you can propagate from additional plants and literally multiply what you have plus have lots of fun doing it. If you have a Climbing Hydrangea you can take a cutting and literally make a new plant.
When to take hydrangea cutting
The best time to take a cutting from your Climbing Hydrangea is between late June and early July.
The goal here is to take a hydrangea cutting in the spring when the leaves are green and lush, full of nutrients. This will give them the highest possible chance of successfully developing a new root structure and propagating.
Tip: Do not take your cuttings until you are ready to propagate. You don’t want to take the cuttings and then leave them in your house for days or weeks before you get everything else ready.
How to take climbing hydrangea cuttings
Once it’s time for you to take your cuttings, make sure you sharpen the gardening pruners you are going to use. If it takes you more than one clean cut to get through you leave your Climbing Hydrangea susceptible to disease or infection in those wounds.
- First, sterilize the tools with a mixture of one part bleach for every 9 Parts water, or a gardening sterilization mixture that you purchased at a nursery such as Jeyes Fluid. You want to do this every time you go to take a cutting so that you don’t accidentally transfer some sort of disease or fungi or bacteria from one plant to another. This will harm a new cutting, reducing the likelihood that it will propagate effectively and it can harm your original Climbing Hydrangea.
- After that, cut lengths that are approximately 15cm. You can take multiple cuttings off of one branch as long as you don’t cut down too far into your host plant.
- Take each of the cuttings and snip away all the leaves until you only have one pair, two leaves, at the top of the cutting. All the others downward should be removed.
How to propagate once you have your hydrangea cuttings
Now that you have the cuttings clipped it’s time to prepare them and propagate your Climbing Hydrangea. You want to start by dipping the end of the cutting into a rooting hormone. This rooting hormone powder will help to discourage any root rot while they are propagating and expedite the growth of the roots so that you can move them outside much sooner.
- Promotes strong healthy roots.
- Contains as natural source of seaweed to increase propagation.
- Also use for dipping plugs all year round.
- For use on soft semi-hard and hardwood plants.
- Use on a variety of indoor and outdoor cuttings.
- Start with the pots or containers in which you’re going to propagate and fill them with your potting soil. Using a long stick, pain, or pencil, make a hole straight down into the middle of the soil.
- Once you have dipped the clipping into the hormone rooting powder stick it into the hole and cover it with soils until such time as it’s able to stand upright. You don’t want it to fall over as soon as you let go.
- Water it immediately from top to bottom to make sure that the water travels all the way through the soil and there aren’t any issues with drainage.
- Cover each of these cuttings for the first month. The goal here is to make a sort of greenhouse effect and there are many ways that you can do this. You can use a plastic bag, plastic wrap, or some type of plastic top to go over your cutting. Whatever you choose you might want to make a tent with something like Chopsticks or skewers so that the plastic cover of whatever making does not touch the cutting. You might have to change the tops for something with more height as your cutting gets bigger or more robust.
If you plan to propagate from cuttings on a regular basis you can invest in propagators that have everything you need in one kit including the trays, a heating pad, a larger container to hold each of the trays, and adjustable plastic lids that have features on them which allow you to control the circulation and air and then easily water when it’s appropriate.
It should take about one month for your Climbing Hydrangea cuttings to be ready for transplantation directly into a larger pot or into your garden but we recommend keeping them in pots for the first 12 months so they get rooted well.
Soon enough you’ll have even more climbers filling your space with stunning flowers.
