2. Planting:

  • Seeds: Water-pepper can be grown from seeds, sown directly in the garden in early spring after the last frost or in late summer for a fall harvest.

3. Care and Maintenance:

  • Watering: Ensure consistent moisture levels without waterlogging the soil. Regular watering, especially during dry spells, is crucial for healthy growth.

  • Mulching: Applying a layer of mulch around the plants helps retain moisture and suppresses weed growth.
  • Fertilization: Water-pepper generally doesn’t require heavy fertilization. A balanced organic fertilizer applied in spring can support healthy growth.

4. Harvesting:
