(Enter your transplant date (or direct sow date) for each crop you are growing. The calendar calculates your estimated harvest start date, the harvest window length, and shows your full season harvest timeline.)
New vegetable gardeners often expect harvests earlier than they happen, then get discouraged when nothing is ready.
Understanding the timeline from planting to harvest — for every crop, at your specific planting date — turns the waiting period from frustrating uncertainty into a concrete countdown. You know what to expect and when.
Enter your planting dates for each crop and this tool builds your complete season harvest calendar — showing every expected harvest start and window on a visual timeline.
Editor’s Note: Days to maturity counts from transplant date (for starts) or germination date (for direct-sown crops). Fast crops: radishes 25 days, lettuce 45–55 days. Medium crops: beans 50–60 days, cucumbers 55–65 days. Slow crops: tomatoes 65–85 days from transplant, peppers 70–90 days, winter squash 85–100 days. These are the averages — actual timing varies with weather, variety, and care.
Days to Maturity — What It Actually Counts
The “days to maturity” on a seed packet is a source of consistent confusion. For crops started indoors and transplanted (tomatoes, peppers, eggplant, broccoli), the count starts from transplant date — not from when you sowed seeds indoors.
For direct-sown crops (beans, carrots, beets, corn), the count starts from when seeds germinate, not from when they were sown.
Both counts assume normal growing conditions: adequate water, appropriate fertiliser, and temperatures within the optimal range for that crop.
Cold springs, heat waves, or pest damage all extend the actual days to harvest beyond the printed estimate. Use the days to maturity as a planning guide, not a hard deadline.
| Crop | Days to Maturity | Count From | Harvest Duration |
|---|---|---|---|
| Radishes | 22–30 days | Germination | 1–2 weeks (harvest quickly or they go woody) |
| Lettuce (leaf) | 45–55 days | Germination | 4–6 weeks (cut-and-come-again) |
| Spinach | 40–50 days | Germination | 3–4 weeks before bolting |
| Bush beans | 50–60 days | Germination | 3–4 weeks |
| Cucumbers | 55–65 days | Transplant or germination | 6–8 weeks |
| Zucchini | 50–60 days | Transplant | 8–10 weeks (harvest every 2 days) |
| Tomatoes (early) | 60–70 days | Transplant | 8–12 weeks |
| Tomatoes (main season) | 75–85 days | Transplant | 8–12 weeks |
| Peppers | 70–90 days | Transplant | 8–10 weeks |
| Winter squash | 85–100 days | Transplant | Harvest all at once at season end |
| Corn | 65–90 days | Germination | 5–7 days at peak (harvest fast) |
Planning a Continuous Harvest Season
A well-planned garden doesn’t produce everything at once — it delivers a steady stream of harvests from spring through fall. The tools for achieving this are succession planting (sowing the same crop multiple times, 2–3 weeks apart) and crop diversity (growing crops with different maturities so the harvest window is always open).
An example continuous harvest plan for a 4×8 raised bed in Zone 6:
- March–April: Radishes, lettuce, spinach, peas — all direct-sown. Harvest May–June.
- May transplants: Tomatoes, peppers, cucumbers. Harvest August–October.
- June direct sow: Beans (second succession), more lettuce, carrots. Harvest August–September.
- Late July: Fall broccoli, kale transplants. Harvest October–November.
For the timing of each planting by zone and frost dates, use our seed starting calculator and frost dates tool together — they give you the exact anchor dates for each succession.
For knowing exactly when each crop is ready to pick, our individual harvest guides give variety-specific cues: when to pick tomatoes covers all tomato types, and when are radishes ready to pick covers the fastest crop in the garden.
Frequently Asked Questions
My tomatoes have been in the ground for 85 days but nothing is ripe yet — is something wrong?
Not necessarily. Days to maturity is an estimate under ideal conditions. Cool springs delay development significantly — tomatoes planted during a cold May or early June may add 2–3 weeks to their expected maturity.
A heat wave above 95°F halts fruit development temporarily (flowers drop, ripening pauses). Pest or disease stress also extends the timeline. Check that the variety matches your climate — a 90-day tomato in a 90-day growing season only works if planting timing is precise. See our when to pick tomatoes guide for the visual ripeness cues that work regardless of calendar days.
How do I know when vegetables are actually ready to pick?
Days to maturity gives you the planning window — visual and tactile cues tell you the exact moment.
- For radishes: size (marble to golf ball) and color.
- For tomatoes: full color development, slight give when squeezed, easy release from the vine.
- For cucumbers: color and size before any yellowing.
- For beans: pods feel firm and full but seeds haven’t swelled inside. When in doubt, our harvest guides for each crop give the specific cues to look for.
