How to grow hydrangeas from cuttings?
Propagating hydrangeas from cuttings is incredibly rewarding and easy! I've expanded my hydrangea collection this way for years:
Take softwood cuttings in early summer from non-flowering stems. Select healthy growth from current season, 4-6 inches long with several leaf nodes. Remove lower leaves, keeping 2-3 sets at top.
Dip cut end in rooting hormone and plant in well-draining mix (I use half perlite/half potting soil). Water well and cover with plastic dome or bag to maintain high humidity. Place in bright, indirect light.
Rooting takes 2-4 weeks. You'll know they've rooted when new growth appears. Gradually acclimate to lower humidity before transplanting.
The best part: cuttings produce identical plants to the parent, preserving those beautiful flower colors! You'll have flowering plants in 1-2 years.

Hey fellow hydrangea lover! I'm a propagation addict and hydrangeas are one of the easiest shrubs to root. Here's my foolproof method:
I take cuttings in June when growth is still flexible but starting to firm up. I look for stems without flower buds. My secret: I use clear plastic cups so I can see root development without disturbing the cutting!
I make my rooting mix with 2/3 perlite and 1/3 peat moss. I water with a weak chamomile tea solution - it has natural antifungal properties. I keep them on my porch where they get morning sun only.
The key is maintaining humidity without making them too wet. I open the plastic bag for an hour daily once roots start forming. My success rate is about 80%! It's so satisfying to fill your garden with plants you started yourself.
The best part is sharing rooted cuttings with gardening friends!
