Sow hollyhock seeds outdoors just beneath the surface of the soil 1-2 weeks before last frost. Seeds will germinate in 10-14 days. Thin to 18-36 inches apart after seedlings have sprouted. Water as needed during dry conditions to keep flowers blooming.

Alcea rosea (Hollyhock) is listed in the Invasive Plant Atlas of the United States.

You can plant hollyhocks from seed now, in the late summer, and you may get blooms next summer. Or wait until late winter or early spring and start transplants indoors. Or, you can plant them outside from seed later next spring. If you wait to plant until next year, you'll most likely have to wait a year for blooms.

Water flowering hollyhocks deeply every week when they're in bloom. Water first-year plants and nonflowering mature ones every two weeks or monthly. Saturate the soil to a depth of 2 feet. Water from beneath to avoid wetting the rust-susceptible foliage.. . . . .364011234509!]0000000000000009783314147327!]
