March Sowing Calendar: What to Plant When

by

March marks the beginning of spring in many regions, making it an ideal time for gardeners to start planting a variety of crops and flowers. Knowing what to sow and when can help ensure a bountiful and healthy garden throughout the season.

Early March Planting

In early March, gardeners in milder climates can start sowing certain vegetables indoors or in protected environments. This early start helps crops mature in time for the peak growing season.

  • Tomatoes: Start seeds indoors to transplant later.
  • Peppers: Sow indoors for a later outdoor transplant.
  • Celery: Begin indoors to ensure a long growing period.
  • Herbs: Basil, parsley, and chives can be started indoors.

Mid-March Planting

As the weather warms, it’s time to direct sow some hardy vegetables outdoors and continue indoor sowing for others.

  • Carrots: Sow directly into the soil.
  • Radishes: Plant for quick germination and harvest.
  • Lettuce: Sow in succession for continuous harvest.
  • Spinach: Sow outdoors for early greens.
  • Onions: Plant sets or seedlings outdoors.

Late March Planting

In late March, most regions can begin planting a wider variety of crops directly outdoors, taking advantage of the increasing daylight and warmer soil.

  • Potatoes: Plant seed potatoes.
  • Beans: Sow directly into the soil.
  • Squash and Zucchini: Transplant seedlings or sow seeds directly.
  • Herbs: Cilantro, dill, and thyme can be sown outdoors.

Flowers and Ornamentals

March is also a good time to start planting flowers and ornamental plants to brighten up your garden. Many annuals and perennials can be started indoors or directly sown.

  • Marigolds: Sow indoors for early blooms.
  • Petunias: Start indoors to transplant later.
  • Sunflowers: Sow directly outdoors once the soil warms.
  • Sweet Peas: Sow outdoors for early flowering.

Tips for a Successful March Garden

To maximize your gardening success in March, consider the following tips:

  • Prepare your soil by adding compost or organic matter.
  • Monitor weather forecasts to protect young plants from late frosts.
  • Use cloches or row covers to extend the growing season.
  • Keep a gardening journal to track planting dates and growth progress.

With careful planning and timely planting, your garden can thrive throughout spring and into the summer months. Happy gardening!
