Instructions

  1. Growing Rosemary in Warm Climates (USDA Zones 8 Through 10)

    • 1

      Buy started plants at the nursery for best results; seeds germinate slowly and erratically - and then only when they're very fresh.

    • 2

      Choose a site that gets full sun or very light afternoon shade and has excellent drainage (raised beds are ideal). Rosemary prefers poor to average soil with a pH of 6.5 to 7.0.

    • 3

      Plant at any time, setting transplants into the ground at the same depth they were growing in their nursery pots. Leave at least 2 feet all around to ensure good air circulation.

    • 4

      Clip leaves or sprigs anytime you need them.

    Growing Rosemary in Cooler Climates (USDA Zone 7 and North)

    • 5

      Buy started plants at the nursery for planting in early spring.

    • 6

      Use a clay pot that measures at least 12 inches deep and 12 inches across and has plenty of drainage holes.

    • 7

      Fill it with a light, coarse potting mix, such as cactus soil with a handful of perlite added. Set the plants into their new quarters at the same depth they were growing in their nursery pots.

    • 8

      Harden off plants when all danger of frost has passed, then move them outdoors (see "How to Harden Off Seedlings").

    • 9

      Water regularly, keeping the soil slightly moist but never wet. During spring and early summer, feed plants monthly with compost tea.

    • 10

      Bring the plants back inside well before the first frost and put them in a sunny south- or west-facing window. If winter sunlight is scarce in your house, augment the supply with fluorescent lights.

    • 11

      Keep the soil moist and mist the plants at least twice a week with tepid water.

    • 12

      Clip leaves or sprigs anytime you need them.
