How do you handle drought conditions in organic farming?
Original post by FarmFresh
Hello fellow organic farmers,
I'm facing a serious drought situation on my farm in the western region. This is my third year of organic farming, and I've never experienced such dry conditions before. My usual irrigation methods aren't keeping up, and I'm worried about my crops.
I'm currently growing tomatoes, peppers, and some leafy greens on about 5 acres. I've been using drip irrigation, but with water restrictions tightening, I need to find more efficient methods.
What strategies have worked for you during drought conditions? I'm particularly interested in:
- Water conservation techniques
- Drought-resistant crop varieties
- Soil amendments to improve water retention
- Alternative irrigation methods that are water-efficient
Any advice would be greatly appreciated. I'm trying to avoid losing this season's crops while staying true to organic principles.
Thanks in advance!

Hi FarmFresh,
Drought conditions can be challenging, but there are several organic approaches that can help. I've been farming in drought-prone areas for over 15 years, and here's what has worked best for me:
Soil Amendments:
Focus on building organic matter in your soil - it's the single most effective way to improve water retention.
- Add well-aged compost (at least 2-3 inches) to your growing areas
- Consider biochar - it can hold up to 6 times its weight in water
- Worm castings not only add nutrients but improve soil structure for better water retention
Mulching:
Apply a thick layer (4-6 inches) of organic mulch around your plants. This dramatically reduces evaporation and keeps soil temperatures lower. Options include:
- Straw (my personal favorite for vegetables)
- Wood chips (better for perennials and trees)
- Leaf mulch
- Living mulch (low-growing cover crops between rows)
I've found that proper mulching can reduce water needs by up to 50% in some cases.
Hope this helps! I'll share more about irrigation efficiency in another post.

Building on what SoilMaster said, I'd like to add some thoughts on drought-resistant varieties that have worked well for me:
Drought-Tolerant Varieties:
For tomatoes, I've had great success with:
- 'Punta Banda' - a determinate variety that's incredibly drought-tolerant
- 'Thessaloniki' - an heirloom variety that handles heat and drought well
- 'Cherokee Purple' - surprisingly drought-resistant for an heirloom
For peppers:
- 'Aji Amarillo' - needs less water than bell peppers
- 'Ancho' peppers - very drought-tolerant once established
For leafy greens in drought conditions:
- 'Red Malabar' spinach - thrives in hot, dry conditions
- 'Jericho' lettuce - bred for desert conditions, more heat and drought tolerant than most lettuce
- Purslane - technically a weed but very nutritious and extremely drought-tolerant
I've also found that focusing on deeper, less frequent watering encourages plants to develop deeper root systems, making them more resilient to drought over time.
