How to Propagate Hydrangeas (From Cuttings, Step by Step)

Early summer is the sweet spot. You want softwood growth - the fresh green shoots that are firm but still bend without snapping. That kind of stem roots fast and gives the young plants a full season to bulk up before frost.

Set yourself a rough calendar. Northlawn takes cuttings around mid-June, pots them up in July, hardens them off in late August, and plants the babies out in early September. Shift those dates to match your own frost timing.

Walk the shrub and look for a shoot with clean green leaves and no bloom on the end. A flowering stem is busy feeding the flower, so it puts far less energy into making roots.

Green, bendy tips root better than old woody wood. Pick a couple of extra stems while you're out there. Not every cutting takes, so a few spares improve your odds.

Find a leaf node, the little bump where a pair of leaves meets the stem. Snip cleanly right below it with sharp bypass pruners. That node is where the roots will push out, so it needs to sit low on the cutting.

Aim for a piece about four to six inches long with one or two sets of leaves left on top. Keep the blades clean so you're not spreading disease between plants.

Strip off the lowest leaves so you have bare stem to sit in water or soil. Then take the big leaves left on top and cut each one in half across the middle.

It looks harsh, but a cutting can't drink through roots it doesn't have yet. Less leaf surface means less water lost, so the stem can spend its energy growing roots instead of holding up leaves.

Drop each trimmed stem into a jar of clean water, one or two per jar, and set them somewhere bright but out of direct sun. This hands-off water method is great for busy or beginner gardeners because there's almost nothing to do.

Change the water every few days so it stays fresh. Prefer soil? Push the hormone-dipped ends into moist potting mix and cover with a clear cup or humidity dome to hold moisture in.

Give it a few weeks and you'll see white roots trailing down into the jar. When they're an inch or two long, the cutting is ready for its own pot.

Fill a small nursery pot with moist potting soil, make a hole, and settle the rooted cutting in. Firm the soil gently around the roots so the little plant stands up on its own and water it in.

Keep the potted cuttings out of harsh afternoon sun while they settle into their new home. A humid, sheltered spot helps them recover from the move. Water whenever the top of the soil feels dry.

Over the rest of the summer each rooted cutting fills out into a small leafy hydrangea. A year on, these babies are still compact, but they'll each carry their first bloom.

When the roots fill the pot and the nights stay mild, get the young plants used to the outdoors. Set them outside for a few hours a day at first, then longer, so they toughen up before the move.

Plant each baby hydrangea in the garden with a spot that gets morning sun and afternoon shade. Water it in well and keep the soil damp while it establishes over the following weeks.
