Readers ask where to begin with zero gear. This is the exact order that wastes the least money: sun first, pot second, mix third, dates last.
- Count your sun. Note how many hours hit your growing spot directly. Six-plus hours grows anything; four to five grows greens and herbs. See which crops fit your light.
- Get one 5-gallon pot with drains. Big pots forgive missed waterings; small pots dry out fast. Common mistake: no drain holes — roots sit in water and rot. Drill holes if the pot lacks them, and set it on feet so water can leave.
- Fill with potting mix. Bagged potting mix — never garden soil, which packs down and chokes roots. Our 3-part recipe costs less per pot.
- Plant by the dates. Enter your ZIP in the planting-date tool and sow on schedule. Then water by the finger test each morning.
Sun hours decide your crops
| Direct sun | Grows well | Skip for now |
|---|---|---|
| 6+ hours | Tomatoes, peppers, beans, cucumbers | Nothing — full menu |
| 4–5 hours | Lettuce, spinach, kale, basil, carrots | Fruiting crops (they sulk) |
| Under 4 hours | Sprouts, mint, cut-and-come-again greens | Most vegetables |
Soil and water basics
Use bagged potting mix, not garden soil. Garden soil packs down in pots and chokes roots. A bagged mix stays loose and drains well.
Check water with your finger each day. Dry two inches down means water now — water until it runs from the drain holes, then stop. Mulch the top two inches to slow drying.
Quick answers
Can I really grow food in pots?
Yes. A 5-gallon pot, bagged mix, and one compact plant like lettuce or bush beans will crop on a balcony. Start small; skip full-size tomatoes until your second season — they need big pots and daily summer water.
What is the cheapest way to start?
One 5-gallon bucket with drilled holes, one bag of potting mix, and a packet of lettuce seed. Under one season of salads, you learn watering, sun, and feeding — the same skills big pots need.
What if I have zero direct sun?
Most crops need at least six hours; leafy greens cope with four to five. Below that, grow sprouts indoors or pick the sunniest window box you have.
