The Tampa Bay Landscape: Monthly Insights
December Edition: Mastering the Dry Season
Welcome to the inaugural post of The Tampa Bay Landscape, your monthly guide to keeping your property lush in our subtropical paradise.
If you are new to Florida, December can feel confusing. The rest of the country is covered in snow, while we are often wearing shorts. It’s easy to think that because it’s warm, the rules haven’t changed. But any seasoned Tampa landscaper will tell you the truth: Winter is not about fighting the cold; it’s about mastering the drought.
We have officially entered Florida’s “Dry Season.” While we don’t have to shovel snow, we do have to manage water, fungus, and frost sensitivity. This month, we are breaking down exactly what your St. Augustine and tropicals need right now.
- The Watering Pivot (Dry Season Logic)
From June to September, we rely on daily thunderstorms to keep our lawns green. Now, the tap has turned off.
The Mistake: Keeping your irrigation timer on the “Summer” setting OR turning it off completely.
The Fix: Your lawn needs about 3/4 inch of water per week. With lower humidity and cooler nights, evaporation slows down, but the lack of rain means your sprinklers are the only source of water. You need to inspect every head this month. A broken sprinkler head in July is forgiven by rain; a broken head in December means a dead patch of grass in two weeks.
- The Silent Enemy: Large Patch Fungus
Walk around South Tampa or Carrollwood right now, and you’ll see perfect green St. Augustine lawns marred by expanding yellow or brown circles. This is Large Patch Fungus (formerly Brown Patch), and it thrives when temperatures drop below 80°F.
The Cause: Overwatering and excess Nitrogen.
The Fix: Do NOT fertilize your lawn with heavy nitrogen right now. It feeds the fungus, not the grass. Reduce watering frequency (but water deeply when you do) to let the grass blades dry out completely between cycles. If you see the circles, apply a fungicide immediately to stop the spread.
- The “No Prune” Rule for Tropicals
It’s tempting to go out and shape up your Hibiscus, Crotons, and Bougainvillea to make the yard look tidy for holiday guests. Don’t do it.
Pruning stimulates new growth. That tender, baby growth is highly susceptible to cold damage. If we get a freak freeze (which happens!), that new growth will fry, and the damage can travel deeper into the plant.
The Strategy: Save the hard pruning for late February or March. If your plants do get nipped by frost later this winter, leave the dead brown leaves on the plant—they actually act as insulation for the living wood underneath.
- It’s Finally “Garden Time”
While the north is dormant, Tampa is entering its prime season for color and vegetables. The scorching heat is gone, meaning you can finally enjoy your garden without melting.
This is the perfect window to install winter annuals that would die in our summer heat. Petunias, Pansies, Snapdragons, and Begonias thrive in Tampa right now. It’s also the peak time for planting herbs and leafy greens. If you’ve been waiting to boost your curb appeal with flower beds, December is the time to install them.
- Weed Warfare
Just because the grass grows slower doesn’t mean the weeds take a break. In fact, winter weeds like Dollarweed, Chickweed, and Henbit love this weather.
Because your St. Augustine or Zoysia isn’t growing aggressively enough to choke out weeds, you need to be proactive. Now is the time for spot-treating weeds. Be careful with “Weed and Feed” products this late in the year (see point #2 about Nitrogen); often, a targeted spray is safer for your lawn’s health than a blanket granular application.
Summary: Enjoy the “Winter”
Landscaping in Tampa isn’t about shutting down; it’s about shifting gears. It’s about protecting your investment from fungal disease and enjoying the flowers that the rest of the country can only see in pictures.
If you would rather spend your weekends at the beach or enjoying the Riverwalk than checking sprinkler heads and fighting fungus, let us help.
