When to Take Stem Cuttings
Hydrangeas are deciduous perennials that thrive in the spring and summer months. The best time to take cuttings is from late spring through early fall, after the plant has leafed out. However, if it’s late in the season, make sure the foliage is still green and that there’s enough time for roots to form before the weather gets cold. Ideally, plan for 6-8 weeks for rooting.
Preparing Cuttings
Start with a healthy, disease-free hydrangea. The cuttings you take will be clones of the parent plant, so choose one you love. Select a young, green stem around 6 inches long, preferably one that hasn’t yet flowered.
Using sharp garden shears, cut just below a leaf node. The cutting should be 3-5 inches long, with at least three sets of leaves. Remove most of the leaves from the lower half, leaving just a pair at the top. For larger-leafed varieties, you can trim the remaining leaves in half to reduce water loss.
Keep the cuttings moist by wrapping them in a damp paper towel and placing them in a plastic bag to prevent them from drying out. If desired, dip the cut ends in powdered rooting hormone to encourage faster root development.
Potting in Soil
Prepare a small container (about 6 inches wide) with damp, sterile potting soil or a mix of equal parts peat moss and perlite. Avoid using garden soil, as it may contain harmful pathogens or excess nutrients.
Moisten the potting mix and make small holes for your cuttings. Place each cutting in the hole, ensuring at least two leaf nodes are buried beneath the surface. Gently press the soil around the stem to keep it in place. Space multiple cuttings at least 2 inches apart.
Water the soil thoroughly, but ensure it drains well. The soil should remain moist, not soggy. To maintain humidity, cover the container with a plastic bag or an upturned milk jug, using stakes to keep it from touching the leaves. Place the container in a sheltered, indirect sunlight area. Check the soil regularly, watering when it feels dry but avoiding overwatering to prevent rot.
Transplanting
In about 4-8 weeks, the cuttings should have developed roots. To check if rooting has occurred, gently pull on the stem. If there’s resistance, the roots are forming. Once you’re confident that roots have established, remove the humidity cover and continue monitoring.
When the hydrangeas are ready, transplant them into the garden or a larger pot. Water well for the first few weeks after transplanting. If they’re not ready for the garden before winter, protect them by placing the pots in a greenhouse or sinking them in the ground, covering them with mulch for insulation until spring.
Conclusion
Propagating hydrangeas from cuttings is a fun and cost-effective way to expand your garden. With just a little effort, you’ll soon have an abundance of hydrangeas to enjoy and share with friends and family. Why spend money on new plants when you can easily grow them yourself?
