Planting
Planting your garden in Arkansas at the right time means the difference between a fast, bountiful harvest and wasted effort — and Zone 7b’s short growing season doesn’t forgive mistakes.
Arkansas gardeners in Zone 7b face a short but sweet growing window—plant at the wrong time, and you risk stunted crops or pest damage. Timing your garden correctly means the difference between a bumper harvest and a disappointing patch of dirt.
For fastest growth, you’ll want to start cool-season crops like lettuce and peas in early spring, while warm-season favorites like tomatoes and peppers need to wait until after the last frost, typically mid-March to April 15.
In this guide, I’ll break down the exact planting windows for Arkansas’s most popular crops, plus proven strategies to extend your season and avoid common mistakes that kill gardens before they even begin.
Arkansas Zone 7b planting deadlines by season: exact dates for each crop type
Arkansas’s Zone 7b offers a 180–210 day growing season, but timing is everything. The last frost date typically falls between March 15–April 15, while the first frost arrives around November 15–December 1.
These windows determine whether your tomatoes thrive or your peppers wilt. Microclimates vary drastically—Delta regions stay humid longer, while Ozark highlands cool faster. Adjust your schedule accordingly.
Cool-season crops like lettuce and spinach love Arkansas’s fall and winter months, while warm-season crops (think squash and beans) need to wait until soil warms to 60°F+.
Below, I’ve broken down the exact planting deadlines for each crop type, plus how to tweak them for your specific Arkansas region. Miss these dates, and you’ll risk frost damage or bolting—neither of which yields a harvest.
Pro Tip: Use a soil thermometer to confirm readiness. Seed packets often suggest 50°F for cool-season crops, but Arkansas’s humidity can delay germination. Aim for 60°F+ for warm-season seeds to avoid rot.
| Crop Type | Ideal Planting Window | Last Chance (Before Frost) | Soil Temp Requirement | Arkansas Region Notes |
|---|---|---|---|---|
| Cool-Season Veggies | Fall: August 1–September 15 Winter: October 1–November 1 |
November 15 (before first frost) | 50–60°F | Ozarks: Plant 2 weeks earlier; Delta: 1 week later due to humidity. |
| Warm-Season Veggies | Spring: April 15–May 15 Summer: June 1–July 15 |
July 31 (before heat stress) | 60–85°F | Northwest AR: Wait until May 1; Delta: Start April 1 if soil warms early. |
| Herbs (Basil, Cilantro) | Spring: March 20–April 15 Fall: August 15–September 10 |
October 15 (before frost) | 55–75°F | Cilantro bolts fast—fall planting is best in Arkansas’s heat. |
| Flowers (Marigolds, Zinnias) | Spring: April 1–May 10 Fall: July 15–August 10 |
September 30 (before frost) | 60–70°F | Northwest AR: Wait until May 1; Delta: Start April 15. |
| Perennials (Daylilies, Coneflowers) | Spring: March 15–April 30 Fall: September 1–October 15 |
No deadline (established plants tolerate frost) | 50–65°F | Ozarks: Fall planting preferred; Delta: Spring to avoid humidity stress. |
For warm-season crops, the April 15–May 15 window is critical. Plant tomatoes or peppers too early, and a late frost will kill them. Use black plastic mulch to warm soil faster in the Delta, where humidity slows heating.
In the Ozarks, wait until May 1 to avoid 32°F nights that can linger into early May.
Cool-season crops like kale and carrots thrive in Arkansas’s fall and winter. Seed them by August 15 for a fall harvest before frost, or try a winter crop in October for spring greens. In the Northwest, aim for September 1 planting—cooler temps there mean faster maturity.
Herbs like basil demand warmth. Start seeds indoors by March 1 and transplant after May 1. Cilantro, however, bolts in Arkansas’s heat—plant it in fall (August–September)
How to extend Arkansas’s short growing season: 5 proven strategies for earlier starts and later harvests
Arkansas’s Zone 7b climate gives us just 180–210 frost-free days, forcing gardeners to work smarter, not harder. The key to beating this short season? Start early, protect plants, and keep harvesting until the first frost.
I’ve tested these five strategies in my own garden—some cut harvest times by 30 days or more!
First, row covers (lightweight fabric) let you plant 3–4 weeks earlier for cool crops like lettuce and spinach. They also repel pests while trapping heat. For warm-season crops, cold frames extend fall harvests by 6–8 weeks by creating a mini greenhouse effect. Both are budget-friendly and easy to DIY.
Next, succession planting ensures a continuous harvest. Instead of planting all your bush beans at once, sow small batches every 2 weeks from May through July. This works especially well for radishes (25 days to harvest) and bush peas (60 days), giving you fresh picks all season long.
Choosing the right fast-maturing varieties is non-negotiable. Swap ‘Brandywine’ tomatoes (85 days) for ‘Early Girl’ (50 days) or ‘Celebrity’ (58 days). For greens, ‘Black Seeded Simpson’ lettuce (45 days) beats ‘Romaine’ (70 days) hands down.
My ‘Early Girl’ tomatoes produced ripe fruit by July 10—just in time for summer BBQs!
Don’t overlook second plantings for fall crops. After harvesting early zucchini in August, I replanted ‘Eight Ball’ zucchini (45 days) in early September. With row covers, I still harvested until October 15, beating the first frost by 2 weeks. This tactic works for kale, carrots, and turnips too.
Here’s the game-changer: combine these strategies. Use a cold frame for fall spinach while succession-planting arugula every 3 weeks. The result? Fresh greens from April through November—no greenhouses required!
🌱 Extending Your Arkansas Growing Season: Pros & Cons
- Pro: 3–4 week earlier planting
- Pro: Pest protection (cabbage worms, flea beetles)
- Con: Requires staking for tall crops
- Con: Reduces airflow (watch for fungal risks)
- Pro: 6–8 week extension for fall crops
- Pro: No electricity needed (passive solar)
- Con: Limited space (best for small plots)
- Con: Overheating risk in summer
- Pro: Continuous harvests all season
- Pro: No wasted space in garden beds
- Con: Requires organization (track planting dates!)
- Con: Pest buildup risk with repeated plantings
- Pro: Harvest before pests arrive
- Pro: Earlier starts in spring
- Con: Smaller yields than heirlooms
- Con: Less flavor depth in some cases
- Pro: Maximizes garden space
- Pro: Fall harvests when pests decline
- Con: Requires soil prep after summer crops
- Con: Weather-dependent (late frosts)
🌱 Pro Tip: Start with 1–2 strategies to avoid overwhelm. I began with row covers and succession planting—now my garden feels like it’s on Arkansas steroids!
Remember: Arkansas’s weather is unpredictable. Always check your local frost dates (use the National Weather Service or Almanac) and monitor soil temps with a thermometer. A 50°F soil is ideal for cool crops, while 60°F+ is needed for warm-season seeds.
With these tactics, you’ll turn Arkansas’s short season into a year-round harvest party. My ‘Early Girl’ tomatoes and fall kale prove it’s possible—now it’s your turn to try! Start small, track what works, and soon you’ll be the neighborhood harvest hero. 🌱
