When to plant Hollyhock?

Hollyhocks thrive in full sun and tolerate a wide range of soils, including loam, chalky, and sandy types, provided drainage is reasonable. They perform best in a sheltered spot out of strong winds, as their tall flower spikes can snap easily. Choose a position at the back of a border or against a wall or fence where they can provide height and structure. Prepare the soil by digging in well-rotted compost or manure to improve fertility and moisture retention, especially on sandy soils. Hollyhocks develop long taproots, so deep soil preparation is important. If your soil is heavy clay, work in grit or sharp sand to improve drainage. Plant young hollyhocks in May, June, or September, spacing them 45 cm apart to allow good air circulation—this helps reduce the risk of rust, a common problem. Dig a hole slightly larger than the root ball, set the plant at the same depth it was growing in its pot, and firm the soil gently around the roots. Water thoroughly after planting to settle the soil and eliminate air pockets. If you're sowing seed directly outdoors, do so in late spring or early summer in a prepared seedbed, covering lightly with soil. Thin seedlings to 45 cm apart once they're large enough to handle. Alternatively, sow in pots in a cold frame and transplant in autumn or the following spring. After planting, water regularly until plants are established. Apply a 5 cm layer of organic mulch around the base to conserve moisture and suppress weeds. In exposed sites, consider staking tall stems early to prevent wind damage.
