This is how I start my hydrangeas. Pool noodles work great

Here are the steps:

1. Start with a new stem: one that hasn’t bloomed yet.
2. Cut at an angle right below a node, say 4 or 6 leaves down.
3. Pinch off the lower leaves, and put in water.
4. Wait for several weeks. You won’t see roots, but the plant will be really green and “fresh” looking.
5. Take the stem, and dip it in rooting powder. Be sure to cover each node (that’s where the roots will pop out)
6. Plant it in good potting soil, and keep it in the shade, and well watered.
7. It’s fun to give to friends in a little pot with a ribbon on it.

Hope this helps and answers some questions.

Loves, my friends.

While starting from a cutting is one way to begin, another approach is to focus on long-term care for big, beautiful blooms. Learn how to successfully grow hydrangeas in pots from start to finish.
