What produce plants best grow in sandy soil?
Look for plants that grow on costal dunes or in desert areas or are local to your area. Take a walk around your area see what is growing. Improve the sand by adding manure, compost, grass clippings, etc. Some new plant selections that are very popular now, and available at most garden centers include Bulbine Frutescens “Hallmark”, and Dianella Tasmatica ‘Blueberry Flax Lily.’ These plants grow well in full sun, sandy soil (both are native to desert climates,) and require almost no supplemental irrigation. Don’t hesitate to call your local small plant nurseries, they likely specialize in plants that suit the area.
