Hollyhock Flower Seeds Packet

When to start?

• plant a week before the last frost
• if start indoors do 9 weeks before the last frost

Where to start and how to sow?

• Direct sow: about a week before last frost. Sow at just ¼ inch deep and about 2 feet apart. Hollyhocks have long taproots, so if seeds are started indoors, use tall, individual pots and transplant early to avoid damage.
• Start indoors: seeds about 9 weeks before the last average frost date. Seedlings can be placed outside two to three weeks after the last frost.

How to keep happy?

• Pick sites sheltered from the wind to prevent these tall plants from flopping and space individual plants far enough apart to promote good air circulation—most hollyhocks are susceptible to the moisture-loving fungal disease rust.
• Positioning them anywhere from 18 to 24 inches apart is best. Hollyhocks are fans of fertile conditions and do best with high levels of nutrients in the soil.
