Step 4: Watering and Feeding
When growing cauliflower at home consistent watering is the key. make sure you keep it well watered but not water-logged and try and keep the moisture in the soil consistent throughout the growing cycle.
Once you’ve transplanted your plants in the garden, water them deeply, about 1-1.5 inches of water a week, either from rainfall or irrigation. Mulching around the plants will help retain soil moisture and suppress weeds.
Fertilize the plants every 3-4 weeks with a balanced organic fertilizer to support healthy growth.
