The hydrangea bush can take many forms, from the paniculata variety's conical panicles to the macrophylla species' mophead blooms. And what makeshydrangea shrubs all the more stunning for your garden? They offer extended flowering periods, showcasing colours like blues, whites and pinks across multiple seasons, with generally low maintenance requirements.
However, while there’s a lot to be enjoyed about potted and pre-grown shrubs and bushes, many wonder, “how do I grow hydrangeas from cuttings?” This guide will offer insights into hydrangea propagation, so you can embrace your inner green thumb and expand the bed!
Cutting back hydrangea bushes can be the start of new life, if you follow these steps and principles.
Pre-grown hydrangea bushes can be planted in the garden at any time of year that theground isn’t frozen or waterlogged. However, propagation needs to be approached with a little more care, with late spring and early summer generally considered the best time to take and plant cuttings. Softer wood can be cut earlier, whereas semi-hardwood cuttings are better taken later in summer.
When propagating hydrangeas, you have to take your cuttings with care. Principles to follow include:
Choosing healthy, but non-flowing stems
Cut around 4 to 6-inches of shoot, just below a leaf node
Remove the lower leaves of the stem
Cut any particularly large leaves in half to reduce water loss
You can dip the cut end inrooting gel to encourage the rooting and establishment of the cutting.
Hydrangea propagation approaches planting similarly to housing established plants. The best results will come from planting in well-drained soil (rich in organic matter) and partial shade. Get the cuttings about 1 to 2 inches deep and space them apart, watering them thoroughly but being cautious not to drown them.
Remember, somehydrangea species are sensitive tosoil pH, with acidic soil encouraging blue growth and alkaline soil creating pinker tones.
After the cuttings are planted, cover them with a clear plastic bag to create humidity – consider it a tiny greenhouse! Indirect light is essential here, as direct sun is likely to cause overheating.
After a few weeks, your cuttings should start to put their roots down. Check with a little tug – resistance means roots have formed. Once they’re somewhat established, carefully dig them out and transplant them into individual pots. Then, they can be grown in a sheltered location, ready to be reintroduced to the bed when fully established.
When following the steps for how to grow hydrangeas from cuttings, some key considerations need to be taken on board.
Using clean, sharp pruning shears/knives to prevent diseases spreading
Hydrangeas need consistent moisture but soil must be well-drained
Provide bright, indirect light throughout
Above all – don’t rush the process. Hydrangea propagation takes time but the results can be amazing.
