This thread is about what YOU can do, even in an apartment, to either relieve your budget or green the planet: doing both at the same time…

Tomatos, strawberries, or squash—at about a dollar per yellow squash or zucchini (ridiculous!) you can do nicely with this. Also cucumbers.
A patio planter. You need: a 5 gallon bucket at Lowes or one of those light, cheap large pots—with hole for drainage, and a bottom tray: you can improvise, but these plants cannot sit half-drowned. The excess water needs a way to leave. And don’t get one of those upside down jobs: they weigh as much as a 12 year old and don’t work well, either.

You need, depending on climate, a sun-sail for screening: you can attach it on your patio, to keep your plant from frying. 45.00 including shipping, from Amazon. Attach sun-sail to protect your pot—if you’re just starting this year, best way to get something that actually produces fast—go to Lowe’s and get one of their grown tomato plants, and choose one of the varieties with smaller tomatoes, because they’ll develop faster. It doesn’t really have time to grow in what’s left of summer if you try something else. Get decent potting soil, and put gravel in the bottom (fishstore, or the parking lot or a roadside). Put a little carbon in the bottom (fishstore); potting soil, and put a wire cone atop it all. Water it daily, just a bit. Fertilize it every 2 weeks. Pick bugs off it. and within not too long you will see ripening little tomatoes. If you have never tasted a sunwarmed tomato right off the vine, you have never tasted a tomato.

Should you have a windstorm and green tomatoes get blown off: slice, dip in egg, bread with Panko or Progresso, fry in oil. Not so great for your waistline, but a real nice dish, and a way to use a disaster. Also if you are up to here with tomatoes and want variety, you can heat vinegar in a pan, pour it over sliced green or half-green tomatoes, add onion slices (to taste), and also cucumber, salt, pepper, maybe jalapenos, add a little water, allow to cool, put it in fridge and forget it for 3 days. Then enjoy as a semi-pickle with a lot of freshness about it.

Yellow squash can be sliced and fried by the above method, or used in soups, etc. If in stew, add it only 20 minutes before serving or it will go to absolute mush.

IF you count that you are saving a dollar an item, not to mention trucking, etc, it’s a way to green up the apartment and get a few meals for nothing. If you get good at this you can widen your efforts.
