- One month after the emergence of seedlings, the landing should be sent to a room with a temperature of about +12 ... + 15 ° C.
- In June, seedlings need to be dived into individual pots.
- The following year, in spring they can be planted in open ground.
When propagating rhododendron cuttings should:
- Cut the cuttings in early spring and root them in a light substrate.
- Put containers with planting material in the greenhouse.
