|We live in Voorhees New Jersey. We planetd a willow oak in the east front of the house in the spring of 2006. It's gets full sun and we do have a spinkler system. However, bottom right side of the tree never gives green leaves in the past. Also, since last summer on that side of tree, the grass turned into yellow and does not grow. Is the tree sick? What can we do to make it better? Thanks

|Because the turfgrass is also showing symptoms, I think there's a soil problem. You can have your soil tested to see if the pH is out of whack. Once you know the pH you can apply iron, lime, or sulphur to correct the pH and bring it back to a more normal range of 6.5 to 7.0. If the soil's pH is very low or very high it can bind up the nutrients and make them unavailable to the roots of your turf and your trees. Start with a soil test and work from there to improve matters. Best wishes with your landscape.
