Transplanting Red Marietta

Transplant seedlings spacing them 5cm apart in trays and grow on. Acclimatise the plants to outside conditions and then plant 15 – 23cm apart in a sunny place.

As Red Marietta is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
