Sowing
Sow in a propagator on a windowsill or in a greenhouse at approx. 15-21°C (60-70°F) using a good quality, moist compost. Cover the seeds only lightly with sieved compost as light assists germination. Germination 10-12 days. Transplant seedlings, spaced out, into trays and grow on. Acclimatise plants gradually before planting out 38-45cm (15-18") apart. Choose a sunny position. Alternatively sow direct outside May/June.
More Info
Feed and water regularly until hollyhocks are fully established. Support their tall stems with bamboo canes as the flower spikes develop. In autumn, cut back the old foliage and faded hollyhock flower stems, and apply a mulch of well rotted manure or garden compost to the base of the plant.
