What to plant this week in Miami, FL
In Miami's frost-free Zone 11a, this week is peak season for harvesting heat-lovers like acorn and butternut squash while sowing daikon radish to fill the gap before winter. With no risk of freezing temperatures, you can focus entirely on managing humidity-driven diseases and extending your harvest window.
The next 7 days
Miami, FLGrowing in Miami right now
- Miami's heavy afternoon thunderstorms often wash away pollinators; hand-pollinate cucumbers or melons if flowers aren't buzzing after a rain.
- The city's porous limestone soil drains quickly but lacks organic matter, so mix compost into planting holes for squash and corn to prevent nutrient leaching.
- High humidity creates ideal conditions for fungal issues on basil and zinnias; water plants in the early morning rather than evening to keep foliage dry.
- Monitor ornamental gourds and bottle gourd vines closely, as their rapid growth can overwhelm container spaces common in Miami balconies.

- Pinch back the tips of basil and shiso to encourage bushier growth before they set seed.
- Clear away any dead foliage from squash and melons to improve air circulation.
Pest & disease watch
- Spider mites are exploding in heat and low humidity pockets, especially on delicate flowers like cosmos and spider flower; blast leaves with water or use neem oil early.
- Aphids frequently attack the undersides of okra and Malabar spinach leaves during this humid stretch; inspect daily and remove by hand if infestations start small.
- Squash vine borers are active now, targeting your acorn and zucchini plants; check stems for sawdust-like frass and insert a pencil to feel for tunnels.
Watering this week
Water deeply in the early morning to reduce evaporation, especially as heat builds up during the day.
Harvest okra pods daily when they are young and tender before they become tough and fibrous.
Miami gardening questions
3Can I still plant cool-season crops like lettuce in Miami right now?
It is too hot for most leafy greens to survive without significant shade cloth or indoor growing; instead, focus on your current harvest list of squash and melons which thrive in the 90s.
How do I deal with excessive heat damaging my zinnias and cosmos?
Mulch heavily around the base of flowers to retain moisture and cool roots, and provide afternoon shade if temperatures spike above 100°F consistently this week.
Is it safe to transplant any seedlings now in Miami's current conditions?
The list shows no plants for immediate transplanting; instead, sow your daikon radish seeds directly into the ground where they will germinate quickly in this warmth.
