The 12 crops ranked
Difficulty here means how many ways there are to get it wrong: whether it needs starting indoors, whether it needs support, how fussy germination is, and how much it minds inconsistent watering.

1. Radish — 22 to 30 days
The fastest thing you can grow and the best possible first sowing. Seeds go in half an inch deep, an inch or two apart, and germinate in 3 to 7 days. They handle frost, so you can sow 4 to 2 weeks before your last frost date.
Sow a short row every two weeks rather than all at once — a whole row maturing at the same moment is more radishes than anyone wants. Pull them as soon as the shoulders swell; left too long they turn pithy. Avoid sowing in midsummer, when heat makes them woody and split.
2. Spinach — 40 to 50 days
Spinach handles cold better than almost anything else in the garden and germinates in soil as cool as 40°F, which makes it one of the first crops you can sow in spring. Sow half an inch deep, thin to 3 to 4 inches.
Its one weakness is heat: once days lengthen and temperatures climb, spinach bolts and turns bitter fast. Treat it as a spring and autumn crop and sow again 10 to 12 weeks before your first fall frost.
3. Leaf lettuce — 45 to 55 days
Choose leaf lettuce over head varieties. Leaf types are cut-and-come-again: take the outer leaves, leave the growing centre, and one plant feeds you for weeks.
The trick most packets underplay is that lettuce seed needs light to germinate. Press it into damp soil and barely dust it over — bury it a half inch and it will not come up. Thin to 8 to 12 inches, and keep it in the shade of a taller crop once summer arrives to delay bolting.
4. Zucchini — 45 to 55 days
Almost aggressively productive. Two plants feed a household, and this is not a figure of speech — plant six and you will be leaving bags on neighbours’ porches.
Direct sow an inch deep, 2 to 3 weeks after your last frost, once soil is above 70°F. Give each plant 24 to 36 inches. Pick fruit at 6 to 8 inches; leave one on the plant and it becomes a baseball bat while signalling the plant to stop producing. Check for squash bugs on stems weekly.
5. Bush beans — 50 to 60 days
Bush beans need no trellis, no transplanting and no thinning fuss. Sow an inch deep, 3 to 4 inches apart, in rows 18 inches apart, and they crop heavily from a small space.
The one rule: wait for warm soil. Below 60°F the seed sits and rots. That usually means 1 to 2 weeks after last frost, not the week of it. Pick every two or three days once they start — regular picking is what keeps new pods setting.
6. Kale — 50 to 65 days
Kale is the longest-serving plant in a beginner bed. Harvest leaf by leaf from the bottom up and a single plant produces for months, straight through light frosts that improve the flavour.
Direct sow a quarter to half an inch deep, or start indoors 6 to 4 weeks before last frost. Thin to 12 to 18 inches. The only real pest problem is cabbage worms, which lace the leaves — check undersides weekly and pick them off by hand.
7. Peas — 60 to 70 days
Peas are among the first things you can plant, going in 6 to 4 weeks before your last frost once soil reaches 45°F. Sow an inch deep, 2 to 3 inches apart.
The mistake to avoid is trellising late. Peas climb from the start, and threading a tangled mat onto netting later is miserable — put the support in the day you sow. They fade once summer heat arrives; pull them and plant beans in the space.
8. Cucumber — 55 to 65 days
Cucumbers are easy in the ground and much easier on a trellis, where fruit hangs straight, stays clean and takes almost no footprint. Sow an inch deep 2 to 3 weeks after last frost, in soil above 70°F.
They dislike root disturbance, so direct sow if you can rather than transplanting. Bitter fruit is nearly always a watering problem — cucumbers are mostly water and need it consistently, roughly an inch a week without long dry gaps.
9. Tomato — 60 to 85 days from transplant
The crop most people start a garden for, and the one where homegrown beats the supermarket by the widest margin. In year one, buy a seedling for $4 to $6 rather than starting seed 8 weeks early.
Two things matter. Plant deep — bury the bottom third of the stem, stripping the lowest leaves, and it will root along the buried section. And install the cage at planting, not in July. Choose a cherry variety for your first attempt: they ripen earlier, crack less and crop for months. Note that the 60 to 85 days is counted from transplanting, not from seed.
10. Carrot — 65 to 80 days
Carrots earn their place on flavour, not ease. Nothing from a shop tastes like one pulled the same day.
They are ranked tenth because germination is genuinely fussy: seed goes a quarter inch deep and the surface must stay damp for up to two weeks. Let it crust dry and nothing comes up. Cover the row with burlap or a board until sprouts appear. Soil matters too — rocky or heavy ground gives forked, stubby roots, so this is the crop that most rewards a raised bed. Thin to 2 to 3 inches or you get green tops and no root.
The two to leave until next year
Peppers (70 to 90 days) and onions (100 to 120 days) are not difficult to grow, but both need 8 to 10 weeks indoors under a light before they can go out. That makes them a seed-starting project rather than a first-sowing project. Onions add a second trap: you have to buy the right day-length type for your latitude — long-day north of roughly 36°N, short-day south of it — or you get greens and no bulb.
Both become straightforward once you have read starting seeds indoors. You can also buy pepper seedlings in year one and grow them exactly like tomatoes, just planted 2 to 3 weeks later, since they sulk below 55°F at night.
Next step
Pick three or four crops from the top of the list, then work out where they are going: the raised beds vs containers vs in-ground comparison settles the setup question in one read. Once you know your crops and your setup, get the dates from the planting calendar for your USDA zone — every crop on this page is in it.
