Dunegrass Maintenance

DSCF0137Dunegrass can be helped to grow with three applications of fertilizer in Spring, Summer and Fall. Typically we use 12-12-12 or similar fertilizer. Slow release fertilizer requires less applications, but it is much more costly.
As soon as possible after the snow melts is the best time to start to eliminate invasive weeds and grasses. I will give a more detailed year round program in another post. However in March we apply a pre-
merge like “Preen” to keep weed seeds from sprouting. We also spray “Round-Up” or a generic equivalent before the green tips of the dunegrass appear. This will kill any green invasives that are growing. More on this later.
