Vegetable gardening comes down to matching watering, feeding, and harvest timing to what each crop actually needs, not a single schedule for the whole bed. Heavy feeders like broccoli want steady moisture at specific points in their growth, which is why our guide to watering broccoli breaks the job into stages instead of a flat weekly amount. Root crops send different signals: beets are best pulled by size rather than by the calendar, and knowing when to harvest beets keeps them from turning woody underground.Storage crops add another layer, since not every variety keeps the same way once it is out of the ground. Our comparison of sweet potato varieties looks at flavor, yield, and how long each type actually lasts in the pantry. Fertilizer timing matters too, especially for crops like garlic that need a hard cutoff before bulbs mature. The guides below cover watering, feeding, pests, and harvest timing across 300 vegetables, organized by crop so you can find the exact stage you are dealing with right now.
Black Diamond watermelon: seed sellers list 35–50 lb fruit in about 90 days. Count your warm days, set the spacing, and keep the rind off wet soil.
The legumes list: 14 garden crops with days to harvest and inoculant needs. In irrigated trials fava fixed 267 lb of nitrogen an acre; dry beans fixed only 62.
Mustard greens bolt in summer heat. Sow in spring and fall, harvest in 40–50 days, cut back for regrowth, and see what the frost-sweetening claim really holds.
Green potato skin holds 75-180x the solanine of a normal tuber. The 12 nightshade garden crops, the inflammation evidence, and why sweet potatoes don’t count.
Flowers dropping, no fruit? Beans stall above 85°F, peppers above 95°F by day, and squash flowers open male first. Find your cause and the matching fix.
Butterhead lettuce needs 60–70 days and 60–70°F. Get the sowing count-back, cultivar sizes, and how to stop lower leaves rotting on wet soil.
Chard is a biennial: one spring sowing gives cuts from week 4 until the mid-20s °F, and it bolts in year two. Sowing, thinning, harvest and frost limits.
Lotus root starts swelling as days shorten. Get the 4 to 8 inch water depth, 4 to 6 month season and 19-inch tub that give a harvest without a pond takeover.
Iceberg lettuce takes 70 to 80 days and cool weather to form a head. Count back from your first 75°F highs to find your sowing date, spacing and fixes.
Grow mung bean sprouts in a jar in about 5 days: soak 8 hours, rinse 3 times a day at 70–80°F, drain at a tilt, and learn the risk rinsing can’t fix.
Water peas about 1 inch a week, lighter until the first flower, then evenly moist through pod fill. Stage schedule, soil-type table and fixes for pod drop.
Water onions about 1 inch a week in 2–3 smaller doses, keep bulb swelling evenly moist, and stop when tops fall. Includes a stage and soil schedule.
Everyone says root a zucchini cutting in water — no extension office backs that up. Here’s the real science, plus how to direct-sow and save true zucchini seed.
Turn a pinched tomato sucker into a free, genetically identical plant in about two weeks — the mechanism, the method, and the one case where you shouldn’t.
Carrots can’t regrow from a cut top — only the greens do. Here’s how to grow carrots from seed correctly, and regrow tops for kitchen greens the right way.
