Ornamec is a very effective, selective grass killer that is safe to use around most shrubs, trees and ground covers. Check their extensive list on the label to be sure your desired plants are considered to be safe.

You may be able to kill grass that is young with only one application. Older plants may take 2 or 3 shots. Ornamec is an expensive product, but worth it. A small amount of concentrate covers a large area when mixed. Be sure to mix it with the surfactant that is included, to get the best absorption of the chemical.

Another choice applies only to succulent ground covers, like ice plant. Magnesium chloride, a salt compound is effective at killing both grassy and broadleaf weeds in ice plant. It burns the weeds but the ice plant has sufficient water reserves to be protected. No water can be applied for 5 days or the weeds may recover. ?Killer - Ice Plant Weeder? is one version of this, available in some areas.

Be sure to read the label carefully to make sure your Red Apple ice plant (Aptenia cordifolia) is listed as safe to use the product on.
