To improve sandy and clay soils add as much organic matter as you can, as it’s better and greener to cope with the soil that you have rather than removing and replacing all the soil. By adding organic matter such as compost and/or manure it not only helps balance your soils water retention, it also adds much needed nutrients to aid in the growth of your plants.
It’s also a good idea to incorporate the use of water crystals in the soil that store and release water over a period of time.
