Choose the right soil. Mulberry trees will grow on many types of soil as long as a good drainage system is provided. Ensure they are not in an area where flooding is common as they do not tolerate being engulfed in water. When possible, well-drained, deep soils are preferred. Opt for slightly acidic soil with a pH of 5.5 to 6.5.
