What soil pH do earthworms like best?
While neutral pH is ideal, earthworms can adjust to pH 5–8 with some species tolerating even more acidic soils. Oxygen requirements also vary among species with some tolerating low amounts. Ammonia and ammonia-based fertilizers are toxic to earthworms due to acidic conditions created by their use.
Why do earthworms prefer moist soil?
By dragging dead leaves into their burrows and eating it there, they are adding organic matter to the garden soil. This helps retain soil water and further breakdown of organic matter adds nutrients to the soil. Earthworms like moist soil. They can survive in dry soils but they are not active.
