Problem with Chilean Mesquite

millerchangAugust 30, 2008

We had a Chilean Mesquite put in this February (24" box) that has been having some problems. First, it leafed out in March, but it never seemed to fill in very well. Second, it has been sapping quite a bit. The sap is clear and hardens up. It has no odor so I don't think it is an infection. Finally, some of the leaves have been turning brown in some parts lately. The tree is on the drip with other plants in the backyard and I have moved the drips further away from the trunk. The tree is watered once a week and gets about 6 gallons of water. After reading some of the forums, I'm concerned that it may not be getting water. I plan on changing the drips to a soaker hose and watering it less frequently but giving it more water at each watering. However, I don't want to give it too much. Any suggestions?

Be sure to check and see how deeply your tree was planted. The soil from the container should be level with the surrounding soil. Planting too deeply restricts the oxygen to the trunk tissue basically suffocating the tree. Gently remove soil near the trunk until you can see the trunk flare or region where trunk tissue becomes root tissue. You may even see the tops of the roots. If this is the case remove about a 12 inch area of soil around the trunk just deep enough so the roots are barely covered with soil.

As far as watering your mesquite, as long as you are watering deeply (to a depth of three feet) you shouldn't need to water any more often than once every 10 days or so in the summer. Extend the interval as the weather cools and by winter water once every three or four weeks. Assuming your tree has a canopy diameter of six feet, apply about 20 gallons each time.
