All Hydrangea varieties from showy Hydrangea macrophylla, to dreamy Hydrangea arborescens are super easy to propagate. Our Hydrangea cuttings we propagated last summer are beginning to bloom this year already!
When is the best time to propagate Hydrangea cuttings?
The best time of year to take Hydrangea cuttings is from spring when the plant is leafing out, to late summer when the leaves are still lush and green.
Hydrangeas are deciduous plants, so it’s best to propagate them and give them some time to develop roots before they go dormant in winter.
Step 1: How to take Hydrangea cuttings
To give your Hydrangea cuttings the best chance to root, start with healthy plants free of pests such as aphids or any disease. Both blooming and non-blooming stems can be propagated easily, but I always try to find stems without flower buds first.
Helpful Tip: don’t let the Hydrangea cuttings dry out during the whole process. Work fast in a shaded area.
Choose 3″ to 5″ long tender green stems, which will root more quickly and easily than woody stems. Cut just below a leaf node. The Hydrangea cuttings should each have at least 3 sets of leaf nodes – see photo above.
Trimmed all but the top two leaves ( or four leaves if the top two leaves are much smaller than average ) from the stem using a clean sharp pruner. Be very careful not to scratch or damage the main stem.
If you are propagating large leaf Hydrangea varieties with leaves 3″ across or larger, trimming the remaining two large leaves in half will reduce the stress on the cuttings to draw up water. For smaller leaf Hydrangeas, it’s ok to keep the leaves whole.

Step 2: How to propagate Hydrangea cuttings
If you don’t use any rooting hormone, no worries, it will just take a little longer. Hydrangea cuttings are so easy to root, especially if you use the “tent” secret shown later. 🙂
Put some rooting hormone powder in a dry zip-lock bag, dip the cuttings in water, shake off excess water, and put the stems inside the bags. Shake the bag till the stems are coated with rooting hormone.
I usually keep the bag open for a few hours to let moisture evaporate, and close the bag with the remaining rooting hormone powder for reuse next time.
Use a stick or pencil to dip a hole in the damp potting mix, and drop each cutting in a hole. Gently push the soil to secure each cutting. Space the cuttings 1″ to 2″ apart minimum.
As you see in the photos above, the goal is to bury at least 1 set, preferably 2 sets of nodes in the soil. Nodes and stems are where new roots will be growing out of!
There are several good rooting medium choices. to propagate Hydrangea cuttings. Seed starter soil mix or a good potting soil are both good to use.
Do not use garden soil or soil mix with lots of manure or fertilizer content as too much nutrients can cause cutting to rot before they take root. A soil-less mix of 50% peat moss ( soak in in water for 30 minutes before use ) and 50% horticulture perlite also makes a great propagation mix.
My favorite propagation secret: boost success with a simple humidity tent!
A big 18″ tall clear plastic bin with lid! This acts like a humid dome / mini greenhouse. After planting the cuttings in moist propagation mix, all you need to do is placing the inside the bin, mist the interior gently, and close the lid.
Check on the cuttings once a week. You may need to mist the interior occasionally. If you don’t have a bin, just remember to water often and keep your new hydrangea cuttings moist at all times, but never soggy. Keep the bin and / or cuttings in a bright warm place out of direct sun.
After about ten days, your hydrangea cuttings will begin to form new roots. Don’t disturb them yet! When a healthy root system forms in 4-6 weeks, you can plant them in the garden or a bigger container.
Keep the newly planted cuttings well watered for the first 2 weeks. Once they are more established, they will require less care. Hydrangeas love dappled shade and moist soil.
I have seen them thriving in full sun in Pacific Northwest or on the east coast. But here in dry and sunny Southern California, they do much better in bright shade with a little morning sun.
Another great colorful plant for shade is Coleus, which looks great with Hydrangeas! Here’s a guide on how to propagate and grow Coleus!
