What to Plant in April 2026 (Complete Zone-by-Zone Guide)

March 03, 2026

April is the month most gardeners have been waiting for — when the serious planting begins. But the timing varies dramatically by zone. While Zone 9 gardeners are already harvesting lettuce and setting out heat-lovers, Zone 4 is just getting started with cold-hardy crops.

Here’s exactly what to plant when, based on your hardiness zone.

Zones 3–4: Finally, Planting Season Begins

Soil status: Should be workable by mid-April, though night frosts are still possible through early May.

Direct sow outdoors (early April):

• Peas — Plant as soon as soil can be worked. They tolerate light frost.
• Spinach — Cool weather crop that actually prefers temperatures in the 50s
• Lettuce — Start with cold-hardy varieties like ‘Arctic King’ or ‘Winter Density’
• Radishes — Fast-growing, ready in 30 days
• Carrots — Plant succession crops every 2 weeks through summer

Mid-April plantings:

• Beets — Both for roots and greens
• Swiss chard — Productive all season, handles light frost
• Kale — Actually sweeter after a light frost
• Onion sets — Plant when forsythia blooms

Transplant outdoors (late April, after soil warms):

• Broccoli starts — Set out 2–3 weeks before last frost
• Cabbage — Hardy transplants can handle 25°F
• Brussels sprouts — Plant early for fall harvest

Continue indoors:

• Start warm-season crops like tomatoes, peppers, and basil for June transplanting

Zones 5–6: Prime Planting Time

Last frost: Mid-April to early May, making this the busiest planting month.

Early April (cold-hardy crops):

• All the Zone 3–4 crops above
• Potatoes — Plant when soil temperature reaches 45°F
• Fava beans — Cool-season alternative to regular beans
• Arugula — Grows quickly in cool weather
• Asian greens — Bok choy, mizuna, tatsoi

Mid-April (as soil warms):

• Herbs — Cilantro, dill, chervil (cool-weather types)
• Sweet peas — Soak seeds overnight before planting
• Larkspur — Direct sow for early summer flowers
• Calendula — Edible flowers that prefer cool weather

Late April (after last frost in Zone 6):

• Bush beans — Soil should be 60°F+ for good germination
• Corn — Plant when oak leaves are “mouse ear” size
• Sunflowers — Direct sow after soil warms
• Zinnias — Easy annual flowers from seed

Transplant timing:

• Cool-season vegetables — Broccoli, cabbage, cauliflower by mid-April
• Warm-season starts — Wait until late April/early May for tomatoes and peppers

Zone 7: The Sweet Spot

Last frost: Early to mid-April, giving you the longest planting window.

Early April:

• Everything from zones 5–6
• Summer squash — Direct sow when soil hits 65°F
• Cucumbers — Start seeds indoors or direct sow late April
• Melons — Start indoors for transplanting in May
• Okra — Southern favorite that needs warm soil

Mid-April:

• Basil — Can transplant outdoors after last frost
• Heat-tolerant lettuce — ‘Jericho’, ‘Muir’, or ‘Summer Crisp’ varieties
• Japanese eggplant — Earlier than traditional varieties
• Cherry tomatoes — Often more cold-tolerant than large varieties

Succession planting:

• Green beans — Plant every 2 weeks through July
• Lettuce — Continue with heat-tolerant varieties
• Radishes — Switch to heat-tolerant types

Zones 8–9: Full Spring Mode

Frost risk: Minimal after early April in Zone 8, essentially zero in Zone 9.

Early April — warm-season bonanza:

• Tomatoes — All varieties can go out
• Peppers — Including heat-lovers like habaneros
• Eggplant — Needs warm soil and air temperatures
• Sweet potatoes — Slips can be planted once soil hits 65°F
• Lima beans — Need warmer soil than bush beans

Heat-season vegetables:

• Southern peas — Black-eyed peas, crowder peas
• Yard-long beans — Asian variety that loves heat
• Malabar spinach — Heat-tolerant spinach substitute
• Armenian cucumber — Actually a melon, very heat tolerant

Transition timing:

• Last chance for cool-season crops before heat sets in
• Start planning summer shade and irrigation needs
• Begin succession plantings of heat-tolerant varieties

Zone 10+: Summer Mode Already

Focus: Heat management and continuous harvests. For the full year-round planting schedule, check the Zone 10A planting guide.

April priorities:

• Harvest cool-season crops before they bolt
• Plant extreme heat-tolerant varieties
• Install shade cloth for sensitive crops
• Start indoor air conditioning seed starts for summer planting

Heat-lovers to plant:

• Tropical peppers — Scotch bonnets, Caribbean varieties
• Heat-resistant herbs — Mexican mint marigold, Cuban oregano
• Tropical vegetables — Chaya, moringa, tropical spinach

Special April Considerations by Zone

Flowers by Zone

Zones 3–6: Pansies, sweet alyssum, snapdragons (cool-weather annuals) Zones 7–8: Add warm-season annuals like marigolds, petunias, impatiens Zones 9–11: Focus on heat-tolerant flowers: vinca, portulaca, celosia

Herb Garden Timing

Cool-weather herbs (all zones): Cilantro, dill, chervil, parsley Warm-weather herbs (zones 7+): Basil, oregano, rosemary, thyme Zone-specific timing: Plant basil outdoors only after nighttime temps stay above 50°F

Tree and Shrub Planting

Best timing: April is ideal for most zones — soil is workable but plants aren’t stressed by summer heat. Zone considerations: Earlier in southern zones, later in northern zones. Water planning: Establish watering schedule immediately, regardless of zone.

Month-End Strategy by Zone

Zones 3–4: Plan for May

• Prepare beds for warm-season transplants
• Start hardening off indoor seedlings
• Plan irrigation for upcoming planting surge

Zones 5–6: Peak Activity

• Maximum planting window for most crops
• Begin weekly maintenance routine
• Install trellises before vines need them

Zones 7–8: Transition Management

• Finish cool-season planting by mid-month
• Prepare for heat with mulch and irrigation
• Plan succession crops for continuous harvest

Zones 9–11: Heat Prep

• Focus on establishment of current crops
• Install cooling systems (shade cloth, irrigation)
• Plan indoor growing for summer heat management

Common April Mistakes by Zone

Northern zones (3–6): Planting warm-season crops too early. Soil temperature matters more than air temperature.

Central zones (7): Forgetting to transition from cool to warm-season varieties mid-month.

Southern zones (8+): Missing the last opportunity for cool-season crops before summer heat.

All zones: Underestimating water needs as temperatures rise and plants grow.

Weather-Watching Tips

Track soil temperature, not just air temperature. Use a soil thermometer 2–3 inches deep.

Watch 10-day forecasts for unexpected cold snaps, especially in zones 5–7.

Plan protection with row covers, cold frames, or water walls for valuable transplants.

Monitor rainfall and supplement irrigation as needed. April often has irregular precipitation.

The key to April success is matching your enthusiasm to your actual planting zone. It’s tempting to rush the season, but patience in the first half of April usually pays off with better establishment and stronger plants throughout the growing season.

Remember: it’s better to plant a week late than a week early in most cases. Your plants will catch up quickly in warming soil and won’t suffer the setbacks of cold stress.
