To propagate hydrangeas, the most common and effective method is by taking softwood or semi-ripe cuttings from the plant. Here is a step-by-step guide based on expert advice:
How to Propagate Hydrangeas from Cuttings
1. Choose the Right Time:
- The best time to take hydrangea cuttings is in late spring to early summer for softwood cuttings or late summer for semi-ripe cuttings
- Avoid taking cuttings from flowering stems; select new growth without flower buds
2. Select and Prepare Cuttings:
- Use sharp, clean pruners or a knife to take cuttings about 4-6 inches long from healthy stems
- Cut just below a leaf node (the point where leaves attach to the stem), as roots will form from these nodes
- Remove the lower sets of leaves, leaving one or two sets at the top
- Optionally, reduce the size of the remaining leaves by half to reduce moisture loss
3. Rooting the Cuttings:
- You can root hydrangea cuttings in water or directly in moist potting mix. Water rooting is easy and low-maintenance, suitable for beginners
- If rooting in soil, dip the cut end in rooting hormone to encourage root development, then plant the cutting in a pot filled with a well-draining mix such as multi-purpose compost with perlite
- Insert the cutting about a third of the way into the soil or water
4. Provide Proper Conditions:
- Keep the cuttings in a warm, bright spot out of direct sunlight
- Cover the pot with a clear plastic bag or use a propagator to maintain humidity
- Keep the soil moist but not waterlogged
5. Monitor Root Growth:
- Roots typically develop within 2-4 weeks
- You can gently tug on the cutting to check for resistance, indicating root formation
- Once roots are established and new growth appears, transplant the young plants into larger pots or into the garden
Additional Tips:
- Start cuttings in the morning when plants are well-hydrated
- Avoid propagating patented hydrangea varieties without permission
- When planting rooted cuttings outdoors, choose nutrient-rich, well-drained soil and space plants according to their mature size
This propagation method allows gardeners to multiply hydrangeas easily and enjoy an endless supply of blooms
