Fixing a Non-Blooming Hydrangea and Propagating Lilacs

Why Hydrangeas Don't Bloom

Usually due to low phosphorus. Apply 10-20-20 granular fertilizer (high phosphorus). Amend soil with compost, aged manure, peat, shredded leaves, and grass clippings to improve tilth, pH, and nutrient supply.

Propagation by Cuttings (Both Plants)

1. Take 6+ inch tender shoots; remove lower leaves.
2. Dip in rooting hormone.
3. Plant 1 inch deep in moist potting mix.
4. Cover with plastic; place in indirect light.
5. Check roots in 2 weeks; remove cover when rooted.
6. Grow indoors over winter; repot as needed.
7. Harden off in spring; plant out after frost.
