Germination usually occurs within 2 to 3 weeks. Transplant seedlings when large enough to handle, spacing 20 to 30 cm apart. Provide supports such as canes, trellises, or netting for climbing. Harden off indoor seedlings and plant out after last frost.

Water regularly during dry spells and feed with a high potash fertiliser to encourage strong growth and abundant blooms. Remove spent flowers to prolong flowering and prevent seed set.
