What to plant this week in Jacksonville, FL
With average minimums holding near 25°F and the last frost officially in the rearview as of Jan 30, Jacksonville gardeners are fully unleashed on warm-weather crops this week. While you might feel like summer has returned, keep an eye out for lingering chill snaps that could stress early transplants like edamame or sweet corn.
The next 7 days
Jacksonville, FLGrowing in Jacksonville right now
- Focus your immediate planting efforts on Daikon radish seeds now; they thrive in our sandy, fast-draining soils once temperatures consistently climb past the frost danger zone.
- Harvest your maturing Acorn Squash and Butternut Squash promptly to prevent rot, as Florida humidity accelerates decay if these gourds sit too long on damp ground.
- Start planning for heavy irrigation needs, as Jacksonville's dry season is approaching and our sandy soil requires consistent moisture to support thirsty crops like cucumber and watermelon.
- Utilize your existing Garlic harvest from this week before the intense mid-winter heat arrives, storing bulbs in a cool, dark place until spring planting.

Seasonal tips
- Start succession planting cool-season greens now that the ground has warmed up slightly after the last frost date.
- Apply a light layer of mulch around established squash and melons to retain moisture as summer heat approaches.
- Divide and transplant perennials like borage and verbena while they are still dormant or just starting to grow.
Pest & disease watch
- Spider mites are becoming increasingly common on ornamental Gourd and Vegetable plants as humidity drops and temperatures rise.
- Watch for aphid colonies building up quickly on young Cucumber and Pole Bean vines in our sheltered coastal microclimates.
- Monitor for slugs and snails actively feeding on tender leaves of Malabar Spinach and Nasturtium during recent overnight rain showers.
Watering this week
Water deeply in the early morning to conserve heat and reduce evaporation during these mild days.
Harvest your acorn and butternut squash soon while the skin is still hardening to ensure long-term storage success.
Jacksonville gardening questions
3Can I still plant vegetables now that the frost date was Jan 30?
Absolutely, as long as you choose cold-tolerant options like Daikon radish or wait for a warm spell before sowing heat-lovers like Sweet Corn. Just ensure you have water available since our soil drains quickly in this zone.
What should I do with my harvested Garlic if I don't eat it all?
Store your cured garlic bulbs in mesh bags inside a pantry or garage where temperatures stay cool but above freezing, avoiding any damp basements that could cause rot.
Which squash varieties are ready to pick right now for the best flavor?
Your Acorn and Butternut Squash should be harvested soon when they develop a deep color and sound solid when tapped, as leaving them on the vine too long invites fungal issues in our humid air.
