April is the great planting month in Zone 7. The average last frost of Mar 15–Apr 1 is behind you, the soil is warm, and everything tender can go out. It is also the month when the first real harvests arrive, so April is both the busiest planting month and the first rewarding one.
What April means in Zone 7
Zone 7 is a generous gardening zone: average annual minimum temperatures of 0 to 10°F mean winters are cold but rarely brutal, and the frost-free season stretches long enough for two full rounds of many crops. The frost-free season lasts about seven months, from late March into early November. The average last spring frost falls in the Mar 15–Apr 1 range and the average first autumn frost in the Nov 1–15 range — USDA zone averages, not exact dates, so check your local extension service before planting tender crops outside. Our planting calendar by ZIP turns them into a month-by-month plan.
With about seven frost-free months ahead, Zone 7 April is about planting the summer garden properly and on time. Tomatoes, peppers, beans, corn and squash all need to be in the ground by late April to mature comfortably before the average first frost of Nov 1–15 — and in Zone 7 there is even time for a second round of many crops later in the year. At the same time, the cool-season crops sown in February and March — peas, lettuce, spinach, radishes and broccoli — are ready to eat.
April task list
- Harden off and transplant tomatoes, peppers and eggplant. 2. Direct-sow beans, corn, squash, cucumbers and okra once the soil is warm. 3. Mulch beds with 2–3 inches of straw or shredded leaves. 4. Set up stakes, cages and trellises before plants get big. 5. Thin carrots and beets sown in March. 6. Keep frost cloth handy — a late frost in early April is still possible.
What to start indoors now
Indoor starting is nearly finished in April, but a few jobs remain. Start a second round of zucchini and cucumbers indoors in mid-April for succession planting, and start basil indoors if you have not already. Start sweet potato slips indoors in a jar of water in early April, ready to plant out in May. Keep growing on any late tomatoes or peppers still inside, and start okra indoors in mid-April — it needs warm soil and a long season. Use clean pots and fresh seed-starting mix, give seedlings strong light, and keep the soil moist but never waterlogged. Work out exact sowing dates with the seed-starting calculator.
What to direct-sow outdoors
Direct sow green beans (50–65 days), sweet corn (60–90 days), zucchini (45–55 days), cucumbers (50–70 days), okra (50–65 days) and yellow squash now that the soil is warm. Sow carrots (60–80 days) and beets (50–70 days) for summer harvest, keep sowing lettuce and radishes (25–40 days) every two weeks, and sow dill, cilantro and parsley outdoors now. Sow pumpkins (90–120 days) in late April for autumn harvest. Prepare the bed first — fork it over, remove weeds, rake it level — then sow thinly, water gently, and thin seedlings to the spacing in the table below.
What to transplant now
Transplant tomatoes (60–85 days), bell peppers (60–90 days) and eggplant (70–85 days) outdoors in April, once nights stay above freezing — harden them off for a week first, and keep frost cloth ready for the first fortnight. Transplant the broccoli, cabbage and kale seedlings started in February, and set out lettuce seedlings into their final spots. Space tomatoes 24–36 inches apart and stake or cage them at planting time. Harden seedlings off for a week first, plant on a cloudy day or in the evening, water them in well, and mulch around — but not against — the stems.
What to harvest this month
April harvests are generous: asparagus spears are at their peak, along with the first peas, radishes, lettuce, spinach and scallions. Cut asparagus spears when they reach 6–8 inches and stop harvesting by early June so the plants can rebuild. Pick lettuce as outer leaves rather than whole heads, and harvest radishes promptly — left too long they turn woody and hot. The first spring broccoli heads are ready to cut. Harvest in the morning, when plants are cool and crisp, and pick little and often — regular picking keeps most vegetables producing.
Frost protection in Zone 7
Zone 7's average last frost of Mar 15–Apr 1 is an average, not a guarantee — check your local extension service and the forecast before putting tender plants out. If frost is forecast after transplanting, cover tomatoes, peppers and beans with frost cloth, old bedsheets or buckets overnight and remove the covers in the morning. Watering the soil before a frosty night helps too, since moist soil holds more heat than dry soil. And remember: tender seeds rot in cold, wet soil, so soil warmth matters as much as the frost date. When a cold night is forecast, water the soil in the afternoon, cover tender plants with frost cloth before sunset, and remove the covers in the morning. The Frost Date Calculator can help you time plantings around your frost dates.

Frequently asked questions
When can I plant tomatoes outside in Zone 7?
In April, after the average last frost of Mar 15–Apr 1, once nights stay above freezing. Harden seedlings off for a week first, and keep frost cloth handy for a late frost in early April.
What can I direct-sow in April in Zone 7?
Beans, sweet corn, zucchini, cucumbers, okra and squash once the soil is warm. All month: peas, lettuce, radishes, carrots, beets, dill and cilantro, which all tolerate cool soil.
What is ready to harvest in April in Zone 7?
Asparagus, peas, radishes, lettuce, spinach, scallions and spring broccoli. Asparagus is the highlight — harvest spears while they are young and tender.
How do I protect transplants from a late frost?
Cover them overnight with frost cloth, old bedsheets or buckets, uncover in the morning, and water the soil before a frosty night so it holds heat. Do not leave covers on during the day.
