AI field guide · refreshed weeklyMemphis Gardening: September 8–14, 2026
You're in zone 8a with 68 days until your average first frost (Nov 15). Soil at 31°C (88°F) is still warm enough for heat-loving crops, but cooling fast. This is prime transition week: summer crops are fading, and fall plantings need to go in now to establish before cold arrives. Your 238 frost-free days mean you can push cool-season crops fairly late into autumn.
Sow outdoors now
Spinach & arugula
Sow directly now; they'll germinate in warm soil and mature through fall. Choose bolt-resistant varieties like 'Space' spinach or 'Roquette' arugula.
Lettuce (leaf varieties)
Direct-sow 'Buttercrunch', 'Oak Leaf', or 'Lollo Rosso' for continuous harvest through November. Thin to 15 cm (6 in) spacing.
Radishes
Fast crop (25–30 days). 'Cherry Belle' or 'French Breakfast' will mature before first frost. Sow every 10 days for succession.
Turnips & rutabagas
Direct-sow 'Purple Top' turnips or 'Laurentian' rutabagas now; they need 60–90 days and improve in flavor after light frost.
Kale
Sow 'Lacinato', 'Winterbor', or 'Dinosaur' directly; they're cold-hardy and sweeter after frost. Thin to 30 cm (12 in).
Start indoors now
Brassica transplants (broccoli, cabbage, cauliflower)
Start 'Calabrese', 'Early Jersey Wakefield' cabbage, or 'Snowball' cauliflower indoors now; transplant out in 4–5 weeks for October–November harvest.
Onions from seed
Start long-day varieties like 'Walla Walla' or 'Ailsa Craig' indoors for transplanting in 6 weeks; they'll establish roots before winter dormancy.
Garlic cloves
While not technically 'indoors', pre-chill garlic cloves in the fridge for 4 weeks, then plant directly outdoors mid-October for spring harvest. Start the chilling process now.
Harvest now
Okra
Pick pods when 7–10 cm (3–4 in) long; they toughen quickly. This is the tail end of the season; frost will kill plants by November.
Southern peas (black-eyed, crowder, purple hulls)
Harvest mature pods or shell fresh for eating. Dry pods on the plant for storage seed.
Late tomatoes & peppers
Pick ripe fruit; green tomatoes will ripen indoors. Frost will end production in 8–10 weeks.
Herbs (basil, cilantro)
Basil is frost-sensitive; harvest heavily before first frost. Cilantro will bolt in heat but thrive in cooler weeks ahead.
Tasks this week
- Water deeply if no rain falls; soil at 31°C dries fast. Mulch newly seeded beds to retain moisture and keep soil cooler.
- Deadhead spent flowers on ornamentals to redirect energy and extend bloom into fall.
- Scout for spider mites and whiteflies on tomatoes and peppers; spray neem oil in early morning if populations spike.
- Pull spent summer crops (beans, squash) and add to compost; clear space for fall plantings.
- Stake or support fall brassicas if wind gusts reach 21 km/h (13 mph) later in the week.
Watch out for
- Heat stress: Soil at 31°C is still hot. Water fall seedlings in early morning and late afternoon; afternoon temps will hit 38°C (100°F) mid-week.
- Dry spell: Only 0.6–8.4 mm rain forecast; irrigate newly seeded beds daily until germination.
- Fungal disease: Humidity is low (34%), but watch for powdery mildew on squash and cucumbers as nights cool; remove affected leaves.
