In addition, be sure to watch for a blue-grey tint and limp areas of your lawn. This is not a fungus. It is caused by dehydration and is an indication that immediate
watering is needed. This will usually occur on tops of mounds, or areas where sprinkler coverage is not adequate. (It is acceptable to water in full sun, it will not burn the blades.)
MOWING- Mow St. Augustine weekly throughout its growing season. Mowing height may vary between 1 and 2 inches depending on preference. Never mow off more than 1/3 of the grass blade length at one time, since plant
injury may result. Always remove grass clippings or use a mulching mower.
FERTILIZING- Fertilize every month during the warm season. Make the first application in the spring when your lawn begins to recover from dormancy. During the warm growing season (March-Nov.) the amount of
clippings generated when mowing will be a "tip-off" to your lawn's fertilizer needs. If you find there are less clippings than previous mowings, your lawn has slowed its growth and fertilizer is probably necessary.
Use Marathon All Season Fertilizer. Follow label directions using the higher rates recommended for Marathon.
INSECTS & DISEASES- St. Augustine is highly resistant to most insects and diseases. Chinch bugs, however, can be a potential problem. Yellow or brown patches may appear when these small insects attack.
Damaging populations are usually most apparent after watering. Use Spectracide per label instructions or consult your nurseryman for other recommendations. If a disease problem is suspected, consult your nurseryman for specific
fungicide recommendations.
DETHATCHING- Generally St. Augustine will require renovation every two years as a result of building up a thick, spongy thatch. Use a vertical mower set a 1/4 to 1/2 inch to dethatch your lawn. Do not set machine
lower than 1/4 inch. This should be done in the Spring After renovation, fertilize and water your lawn to speed up recovery.
DORMANCY- St. Augustine will slow its growth in the Fall. When the first frost occurs your lawn will turn a straw-like yellow. Sometimes the grass blades may have red or purple streaks. During dormancy, water,
fertilizer, and mowing will not be necessary. Green color can be artificially restored using a turf dye. Consult your nurseryman for product recommendations.
