Sow Double Hollyhock Seeds in well-drained soil and cover them lightly. Keep the soil evenly moist during germination and provide full sunlight after seedlings emerge. Transplant carefully because hollyhocks develop a taproot, and choose a location with enough space for their tall flowering stems.
Some hollyhock varieties can flower in their first growing season when started early under favorable conditions. Others behave as biennials and typically produce foliage in the first year before flowering in the second. Flowering time depends on the variety, planting date, and climate.
Grow Double Hollyhocks in full sun with fertile, well-drained soil. Water consistently during dry weather, provide support for tall stems when necessary, and allow good airflow between plants. Monitor foliage for rust, a common hollyhock disease, and remove affected leaves promptly.
