It is soil, or dirt, that repels water not allowing water to soak in. Get a hose end sprayer. Here’s a quick fix. Wetting agents act like a detergent to reduce the surface tension of the water, thereby helping it soak into the soil. Peat moss is a fantastic material but if it is left to dry out it can then cause a mixture to become hydrophobic.

Healthy soil with a balanced and diverse microbial population doesn’t tend to get hydrophobic. This will cause an explosion in the population of microbes in the soil. sand) are more prone to water repellency as it takes less hydrophobic material to coat individual particles, compared to silt or clay.
