To answer your question about what to plant and sow in a raised bed in March, it depends on your specific climate and growing zone. However, here are some general suggestions:

  1. Cool-Season Vegetables:
    • Leafy greens like lettuce, spinach, and kale.
    • Root vegetables like carrots, radishes, and beets.
    • Peas and other legumes.
    • Broccoli, cauliflower, and cabbage.
  2. Herbs:
    • Parsley, cilantro, and dill.
    • Chives, thyme, and rosemary.
  3. Flowers:

    • Marigolds, calendula, and nasturtiums.
  4. Sowing Seeds:
    • Follow the specific instructions on the seed packets regarding sowing depth and spacing.
    • Keep the soil moist while the seeds germinate.

Regarding how to fertilize the soil in a raised bed, there are several methods you can use. You can apply organic compost or well-rotted manure before planting to improve soil fertility and structure. Additionally, you can use organic slow-release fertilizers or organic liquid fertilizers throughout the growing season according to the instructions on the product label.

As for an “Anbauplan Hochbeet” or planting plan for a raised bed, it would be helpful to consider the following factors:

  • The amount of sunlight your raised bed receives.
  • The size and dimensions of your raised bed.
  • Companion planting principles (pairing compatible plants together).
  • Succession planting (planting different crops in the same space as others are harvested).

Keep in mind that different plants have different spacing requirements, so be sure to research and plan accordingly. Also, consider crop rotation to minimize pest and disease issues.

It’s always a good idea to check with local gardening resources or consult a gardening expert to get specific recommendations based on your location and growing conditions.
