March is an excellent time to plant strawberries in Oklahoma. They are easy to grow and produce a good crop with reasonable care. June-bearers are the most widely planted type of strawberry. They produce one crop per year, with the majority of fruit ripening in June. Make planting holes deep and wide enough to accommodate the entire roost system without bending it. Be careful not to plant too deep. The root should be covered but the crown should be right at the soil surface. Provide adequate space for sprawling. Set plants about 20 inches apart, and leave four feet between rows.
