Spring is the time to turn your attention to your Landscape. Here are some tips to help get your landscape off to good start.

• Winter Lawn Coversion: If your lawn was overseeded with winter rye grass now is the time to begin converting back to your summer grass. In Phoenix, summer grass is usually Bermuda & more likely Hybrid Bermuda.
• Mowing: By now you should have already begun lowering your mowing height to allow sunlight & air to get get down into the Bermuda grass
• Verticutting is not advised to remove the ryegrass because this will not give the dormant Bermuda grass a chance to begin growing
• Mowing height: Should be about 1" for Midiron & Bobsod & about 1/2" to 3/4" for tifway & tif green. Do not mow more than 1/3rd of the height in one mowing 
• Fertilizing: As you drop your mowing heights & the soil reaches 65 degrees you should begin fertilizing to stimulte the growth of Bermuda grass. In the first few weeks of April you can begin applying 21-0-0 (Amonium Sulfate) @ 5 lbs per 1000sq.ft. Repeat this application in Late April
• Watering: Most all Bermudagrass problems in Arizona are associated with watering. Do not turn off your water during the Spring to try to allow the winter rye grass to dye out. Doing this will hurt your Bermuda grass. During april you should be watering every 2 to 3 days to a depth of 8" to 10"
  
• Plants & Trees: Spring is a good time to cut back all of your frost senitive plants if you havent already done so. Plants like Lantana, Bougainvillia, Hibiscus respond well to cutting back.
• Roses: As the tempearture warm up aphids & thrips can become a problem on Roses. It is best to use a fertilizer that contains systemixc inse`cticide as well. Also begin to watch for powdery mildew on the leaves that appear dust or white. Treat with a fungicide if necessary
• Trees: Most trees only require that dead branches & limbs be removed
• Weeds: I'm sure you have noticed weeds are popping up like crazy. It is best to get after them quickly & stay on top of them by spraying them with an herbicide such as RoundupR

Happy Gardening!!
