Gardening Tips for March for Whitewater, WI

Midwest Region

  • Start some vegetable seeds indoors, such as broccoli, cauliflower, Brussels sprouts, and cabbage. (See our Best Dates to Plant chart on Almanac.com/Gardening.)
  • Prune trees and shrubs if they're susceptible to disease if pruned during warm weather. (Prune while they're dormant.)
  • Prune dormant fruit trees; the fruit will be larger if it has more room to grow.
  • Before planting outdoors, have your soil tested. Find your local cooperative extension on Almanac.com/Gardening.
  • Continue providing food and water for the birds and other wildlife.
  • Move potted plants to containers that are about 2 inches larger in diameter than their current pot.
  • Trees, shrubs, and perennials can be planted as soon as they are available at the nurseries.
  • Keep the roots of mail order plants from drying out and plant them as soon as conditions allow.
  • Sow some flower seeds indoors now, such as petunia, salviaa, snapdragon, and verbena.

  • Fertilize your perennial beds with a balanced fertilizer, such as 6-12-12, and your vegetable garden with 12-12-12.
  • Don't work the soil if it's too wet. It should feel like crumbly cake in your hands.
