June Gardening Tip

Check irrigation systems:

jun1_lgAs hot weather begins, it is time to turn on the irrigation system. Take time to check for broken heads, leaks, clogged drip emitters, and sprinklers that are malfunctioning. Improper irrigation can lead to wasted water or plant problems with over or under irrigation. Avoid daytime watering. Set your timers to water at night or early in the morning to conserve water. Make sure lawn sprinklers don’t spray into landscape beds since these beds should be watered separately to avoid over watering. Check sprinkler heads to avoid over spray onto impervious surfaces such as driveways and walks to conserve water. To also conserve water, be sure your beds have a good layer of mulch to reduce surface evaporation; increase mower height to avoid lawn burnout.

Nutsedge:

This grass-type weed is recognized by its shiny light green/yellow color and triangular stems. It produces many tubers at the end of rhizomes; from these tubers, many plants are formed. Tuber sprouting is promoted by moist soil conditions, hence nutsedge growth in wet areas. Nutsedge is very hard to control because it produces so many tubers. Mulching over it does very little to control it because it can readily grow though mulch. Pre-emergent herbicide, if applied in early spring, will help in the tuber sprouting. The post-emergent herbicide Sledgehammer, applied in woody landscapes and turf, has been found to be very effective. Roundup or products like Roundup can be effective. The biggest problem with this herbicide is the nutsedge leaf has a very shiny waxy coat, which can initially be impermeable. The use of Sticker is very important. [Read more…]
