Hi all! I’m poor. I’m attempting to get my balcony garden started without spending more than 30 dollars. (I’m probably nuts, I know.) It looks like a good chunk of that will be going to a water hose and sink attachment so I don’t have to haul a milk jug of water back and forth a hundred times, so I’m hurting a bit on funds for fertilizer. To make matters worse, the landlord says I’m not allowed to compost anywhere in the apartment or on the property. (I would just hide it under my kitchen sink, what she doesn’t know won’t hurt her etc, but there’s other reasons why I can’t unfortunately.)
Is there any option for fertilizing my plants with like… five dollars left? If I mix coffee grounds and eggshells into the soil will it do anything other than bother the local slugs? I’ve seen that stuff about letting plant scraps sit in a bucket to make “tea” but what I read said it can’t replace fertilizer - is there a way to make it so that it can?
I have a bag of epsom salts, a strong appetite for veggies, and the willingness to steal the neighbor’s lawn clippings if I must.
I’m also willing to accept that I may have to forgo the water hose C:


Coffee grounds and eggshells will go a long way, but they aren’t a substitute for any other augmentation.
I wouldn’t even consider composting in an apartment - the logistics are just too painful in such a small space (and with long composting timelines).
So about the watering - the cheapest thing you could do is get a faucet aerator-to-hose adapter. It screws into the aerator on your sink and lets you screw on any regular garden hose fitting. The down side is that many faucets don’t like seeing back pressure when the faucet is on, so you could damage your faucet if you turn a valve off at the end of the hose. One option is just “don’t turn it off”, or look at a waterbed filling/draining kit. It’s got a sink adapter very similar to the metal one but it lets some water hiss through under pressure.
Another possible fertilizer source would be an all purpose chemical fertilizer from a dollar store. You don’t get much but you also don’t need much. Definitely not as natural as rolling your own compost, but a lot more practical in a small space.
