St. Augustine Lawn Care

Application 1 Early Spring

ferti•lome® St. Augustine Weed & Feed should be applied early in the spring when the grass begins to turn green & the weeds are actively growing. Apply and water in.  If the yard is dry, water the day prior to application.  This is a slow release 15-0-4 fertilizer with 1% added Iron for a darker green. This has a very effective weed killer that kills existing weeds and also prevents new weeds from coming up for up to 2 months. 

For more thorough weed control spray with ferti•lome® Weed Free Zone 10-14 days later.


Application 2 April/ May

ferti•lome® Weed-Out Plus Lawn Fertilizer should be applied April-May. Apply when the lawn is wet, water in 24 hours after application. This has quick and slow release 25-0-4 fertilizer that will feed up to 2 month. It also has a fully systemic broadleaf weed control, killing over 200 types of weeds. 

For more thorough weed control spray ferti•lome® Weed Free Zone 10-14 days later.


Application 3 June

ferti•lome® Lawn Food Plus Iron should be applied in June. Apply and water in. This has a little quick release fertilizer for a fast green-up, but mostly slow release 24-0-4 fertilizer that will feed over 2 months. This also has 3% added Iron for a very deep, dark green that is long lasting.


Application 4 Fall

ferti•lome® Winterizer for Established Lawns should be applied in the fall to both lawns & shrubs. This has a 10-0-14 fertilizer. The nitrogen enables turf, trees & shrubs to withstand the rigors of winter better and easier. Its effects are similar to putting on an overcoat in the winter. Potassium is used to increase cold hardiness and recover from summer stress. Apply and water in. 

For additional weed control apply ferti•lome® Winterizer & Weed Preventer II for Southern Grasses w/ Dimension. This has the same great fertilizer plus a weed and grass preventer.  Water in.


Application 5 Winter & Spring

Hi-Yield® Turf & Ornamental Weed & Grass Stopper containing Dimension may be applied in early winter and again in late winter/early spring in areas where weeds are a problem.  Apply and water in, if you can't water in, do so within 3 to 4 weeks.

This has no fertilizer, because you don't want to stimulate weed growth through the winter months when the St. Augustine is dormant, however it does have a weed and grass preventer that prevent crabgrass and other weeds from germinating.
