Instructions

    • 1

      Look for seedlings at your local nursery in the spring - starting with seedling is the easiest way to plant mallow.

    • 2

      Consider starting mallow from seed as an alternative. It's fairly easy, even for beginners.

    • 3

      Plant seedlings 10 to 12 inches apart in dry soil that's only moderately rich; plant after your region's last frost date.

    • 4

      Start seeds in peat pots indoors six to eight weeks before the last frost date. Transplant seedlings into garden after last frost.

    • 5

      Water only when soil becomes very dry.

    • 6

      Stake plants if they show signs of toppling. Simply take a wooden stake, drive it into the ground near the plant, and tie the plant to the stake with soft twine or plastic strips.

      Pull plants out of the garden after the first frost.
