How to care for garden hydrangea seedlings?
Garden hydrangea seedlings are sensitive to too high salt concentration in the substrate, therefore you must use very soft water (decant, preferably rainwater) to water them. The seedlings must not wilt. But excessive watering causes them to rot, so regularly observe the seedlings and adjust the doses of water to the needs of the plants.
Rooted hydrangea cuttings should overwinter in a frost-free place. After the leaves fall, cover them with dry peat up to the tops.
In the spring of the following year, hydrangea seedlings need to be hardened. This means getting used to cooler temperatures and stronger sunlight.
For this purpose, you can put the plants outside during the day. Over time, they should also be left overnight. After about 10 days of hardening, you can plant new hydrangeas in the garden.
