Lawn Care in St Augustine, FL for Sandy Soil
Lawn care in St Augustine means working with warm humid air that loves growing fungus as much as grass.
Lawn care built for St Augustine
Between the salt breeze off Matanzas Bay and afternoon humidity thick enough to swim through, your grass has opinions about how it wants to be treated. St Augustine sits in Florida's warm humid zone where fungus thrives almost as easily as turf does.
Sandy soil (92% sand, if we're being specific) drains faster than you'd expect. Sunday builds lawn plans around these local quirks so your yard actually works with the climate, not against it.

St. Augustine lawns grow in sandy soil that drains fast (almost too fast). The warm, humid climate loves St. Augustinegrass, but so does fungus. Your biggest challenge? Keeping moisture balanced without inviting trouble.
Sandy soil changes everything about lawn care
That 92% sand means water rushes through like it's late for something. Water deeply but less often to encourage roots to dig down. Skip the midday sprinkler sessions (hello, fungus). One common mistake: fertilizing too heavily, thinking sandy soil needs more. It doesn't hold nutrients long, so lighter, more frequent feeding works better.

Best Lawn Care Products Ever
I love what Sunday is doing for my St. Augustine lawn in Orlando, Florida. And the weed spray is truly amazing. It works just like advertised, within 30 minutes!

It's A Beautiful Thing
We dropped a well known Florida based lawn and pest control service. We began using Sunday products and couldn't be more pleased with the results. The lawn, it's St. Augustine grass, has never looked better. Very thick and plush green carpet like lawn. Pests are no longer an issue ie bugs, spiders, roaches are all gone. Grubs eliminated in the yard help promote a healthy lawn and fixed the mole problem. Finally, all of this for half of the price I was paying the "experts".

Greener than it was before
Works great to green up my lawn, but doesn't help to fight weeds much. St. Augustine grass weeds apparently are stronger than St Augustine grass.

Growing grass in St Augustine, FL
St Augustine's warm humid climate and sandy soil make it friendly territory for warm-season grasses. The challenge? Humidity invites fungus, and sandy soil drains fast. Time your planting right and you're golden.
Sandy soil drains quick, so water smarter
Spring planting works best from late March through early May, when soil temps climb and roots can dig in. For St. Augustine grass (the local favorite), sodding or plugging beats seeding since true seed is hard to find. One common mistake: overwatering sandy soil, which just washes nutrients away. Water deeply but less often.
