HOW TO GROW

• Work a 2-inch layer of compost into a well-drained garden bed. Select a site that receives at least six hours of direct sunlight, and isn't prone to standing water at any time. Smooth the soil surface with a rake after amending.

• Sow the hollyhock seeds directly on the soil surface, because they require light to germinate. Space the seeds 6 inches apart in rows set about 18 inches apart. Press on the seeds lightly so they have full contact with the soil, but do not cover them.

• Mist the bed with a gentle spray of water, so the seeds aren't washed away. Water as needed to keep the soil moist until the seeds germinate, which takes approximately 14 days.

• Water the hollyhocks about once a week, providing about 1 inch of water each time. Water frequently enough so the top 6 inches of soil doesn't dry out completely. Keep the foliage dry when watering, to minimize fungal disease problems.
