Houston gardeners plant for deluge and drought. We delegate water-lovers to low spots and less-thirsty types to well-draining areas so each can pull through wet and dry cycles. June can be a toss-up, stressing the importance of using water-wise plants. The month began on a hot, dusty note, stranding many gardeners at the end of the water hose considering xeriscapes. While there has been some rainfall relief, the need for low-water plants continues. Mid- to late summer is ideal for planning low-water additions to your garden. Fall is ideal for planting. If you wish to start with trees, here are 10 drought-tolerant species to consider:
