Trees and shrubs. It's generally a good idea to plant these larger landscape plants in the cooler months, but you can plant them now if you take a little extra care. Dig a hole twice as wide as the root ball of the plant, then add a little bonemeal or rock phosphate to the hole. (Follow the package directions for amounts.)Plant and water in thoroughly. Spray some liquid seaweed over the planting area for added nutrients. Irrigate regularly during the first growing season (two to three times a week).Turfgrass and grass seed. Consider planting a native grass mix of buffalograss, curly mesquite and blue grama in a sunny part of your yard — these grasses are drought tolerant and sturdy enough for foot traffic. Be sure to prepare the area thoroughly before sowing grass seed — follow the directions on the package — and keep it moist until the seed has sprouted. If you want to add sod for a more instant lawn, look for pieces of St. Augustine or zoysia, both of which are somewhat tolerant of light shade. Always follow turfgrass recommendations from experts in your area, such as a trusted nursery or your county extension office, when making grass selections.
