Heat transition — spring window is closing for cool-season crops
| Vegetable | When to Plant | Soil Temp | Notes |
|---|---|---|---|
| Tomatoes | Transplant after last frost | 60°F+ | Buy starts or transplant home-started plants after last frost date |
| Peppers | Transplant after last frost | 65°F+ | Need warm soil; wait 2 weeks after tomatoes |
| Peas | Direct sow as soon as soil workable | 45°F+ | Cool-season crop — plant early April in zones 5-6, can't handle heat |
| Lettuce | Direct sow or transplant | 40°F+ | Best spring crop; succession plant every 2 weeks for continuous harvest |
| Beans | Direct sow after last frost | 60°F+ | Don't transplant; wait for warm soil or they rot |
| Cucumber | Direct sow or transplant after frost | 60°F+ | Fast-growing; direct sow is often better than transplants |
| Potatoes | 2-4 weeks before last frost | 45°F+ | Plant seed potatoes 4 in deep; frost kills tops but tubers are fine |
| Carrots | Direct sow 4-6 weeks before last frost | 45°F+ | Need loose, deep soil; thin to 2 in apart for good roots |
| Flower | April Timing | Zones | Notes |
|---|---|---|---|
| Pansies & Violas | Early April transplant outdoors | All | Hardy to 20°F; perfect spring color that blooms until summer heat |
| Sweet Peas | Direct sow in early April | All | Cool-season climber; sow early, won't survive summer heat in most zones |
| Snapdragons | Transplant in April | All | Cool-season; transplant starts outdoors in April before summer heat |
| Zinnias | Direct sow after last frost | All | Direct sow outdoors after frost; hate transplanting. Super fast (50-60 days) |
| Dahlias | Plant tubers April–May | All after frost | Plant tubers 4-6 in deep after last frost date |
| Marigolds | Direct sow after frost or transplant | All | Easy, fast; direct sow after last frost for best results |
| Sunflowers | Direct sow after last frost | All | Direct sow only — hate transplanting. Plant 1 in deep, 6 in apart |
| Cosmos | Direct sow after frost | All | Very easy from seed; thin to 12 in apart. 8-12 week bloom time |
No — April is actually the optimal spring planting month for most of the US. Cool-season crops like lettuce, peas, and kale can go in immediately (even with frost risk). Warm-season crops like tomatoes and peppers go out after your last frost date, which falls in April for zones 7-8 and in May for zones 5-6. The only risk is planting tender plants too early — check your specific last frost date before planting warm-season crops.
For summer bloom: plant zinnia, marigold, sunflower, and cosmos seeds directly in the garden after your last frost date. These fast-growers bloom in 8-12 weeks. For earlier color, buy started annual transplants (marigolds, petunias, geraniums) after last frost. Dahlias planted in April will bloom July-frost. Zinnias are the fastest payoff — seed-to-flower in 8 weeks.
Yes — April is excellent for perennial planting. The soil is workable, temperatures are moderate, and plants have the whole growing season to establish roots before winter. Bare-root perennials (hostas, daylilies, peonies, coneflowers) should be planted as soon as received in early spring. Potted perennials can go in anytime through fall, but spring planting gives best establishment results.
April is ideal for planting trees and shrubs — this is the best planting window for woody plants in most of the US. Plant before or immediately after bud break. Bare-root trees (fruit trees, shade trees, berry bushes) should be planted in early April before dormancy breaks. Container-grown trees and shrubs can go in anytime the soil is workable. Water thoroughly for the first full season.
In April, start: cucumber and squash seeds indoors (4 weeks before your last frost), heat-loving basil, eggplant if not yet started, and fall brassica crops (broccoli, cabbage, kale) in late April for summer planting. In zones 5-6, start tomatoes and peppers NOW if you haven't already — you're running tight on timing. Sweet potato slips should be started indoors April-May for warm-climate gardens.
Your last frost date (the date after which frost is unlikely in spring) determines when to plant tender crops outdoors. Find it at: NOAA Climate Data, Old Farmer's Almanac frost date calculator (almanac.com), or your local university extension service website. General guide: Zone 4 = May 15-30, Zone 5 = May 1-15, Zone 6 = April 15-May 1, Zone 7 = March 15-April 15, Zone 8 = February 15-March 15, Zone 9 = January/frost-free.
