Sow hollyhock seeds indoors from April-May, 1/2 inch deep in a tray of compost. Water well and keep moist. They germinate easily in temperatures of 16 – 21 degrees C (61 -70 degrees F) Seedlings usually appear in 21 – 28 days. Transplant individually when large enough to handle to 3-inch pots. Always hold by the leaf – never by the stem. Gradually accustom young plants to outside conditions, before planting out into well-drained soil, June-October, 2 foot apart. Or
Alternatively, sow seeds directly in the ground where you want them to grow in May – June.
Hollyhock seeds can also be sown in autumn and the young plants over-wintered in a cold frame or cold greenhouse, to flower the following year.
The plants need plenty of room – space them 18 – 24 inches apart at the back of the border.
Water seedlings and young plants regularly, ensuring the top 6 inches of the soil is damp but not soggy, in the first few months. After that, the plants should only need water in prolonged dry or hot spells.
