Desert soil is often sandy, alkaline, and packed with caliche. To grow a lush garden, you must transform this environment. We dive into the best organic amendments and natural techniques to improve your soil health.
Breaking Down Caliche and Sand
The first step in desert soil preparation is addressing caliche—a natural cement-like layer. Breaking through this layer is vital for drainage. Once cleared, incorporating high-quality compost and aged manure will add the necessary organic matter that sandy soils lack.
Lowering pH Levels Naturally
Most desert soils are highly alkaline, which can lock out essential nutrients. Adding elemental sulfur or acidic organic materials like peat moss can help lower the pH over time, making nutrients more available to your vegetable crops.
