Leland Cypress and Cherry Laurel trees that have insects eating the trees from the inside out. Sap is leaking out from several places of the trunk of the Cypress and in the base of the trunk of the Cherry Laurel. Also, we have Azaleas that have tiny white spots on the leaves. Fescue grass has died in some spots showing dark brown dirt.

In order to make a recommendation for insect control, you'll need to collect some of the insects and have them identified - either at your local cooperative extension office, or at a well staffed nursery. Once you know what they are you can choose the appropriate insecticide. Not all pesticides will control all insects on all plants so proper identification is really important.

Oozing sap can indicate an injury, either from boring insects or from a misplaced weed whacker. Healthy trees can heal over physical wounds, but may need some help if the injury is from boring beetles. Inspect the areas for tiny holes which will indicate borer damage.

You can rake over the bare spots in your lawn and overseed the bare areas. Sprinkle a light layer of peatmoss over the seeds to help keep them moist and to keep birds from feasting on the seeds before they have a chance to sprout.

Good luck with your landscape!
