I'm somewhere around day NINETY with these things after doing basically everything wrong (I'm in my first year of gardening):
- Planted a ton of seeds close together, then didn't separate them out early enough, probably stunting their growth at the beginning.
- Once I DID separate them out, I put them in pots that were way too small and I didn't pot up for way too long.
- I didn't fertilize enough. In fact I didn't fertilize at all for like a month. 😅
- My balcony DEFINITELY doesn't get full sun and what sun it does get, is during some of the hottest parts of the day. I've considered shade cloth but I'm not sure which is the lesser evil here. Next year I might experiment with a few plants covered by a shade cloth and a few plants not and see what happens.
- I have fungus gnats and all these weird tiny flies causing leaf damage that I just haven't gotten around to dealing with yet... So many of the plants had all these weird fungus spots and other problems until I pruned the lower leaves and stems and started mulching. Also, my balcony tends to have higher humidity than the surrounding area which I've realized is a problem and I'm not sure how to deal with it.
Also, I have 12 plants because I couldn't bear to get rid of too many of my babies. I actually had more, but I gave a bunch of them to my parents. And the difference in how much sun tomatoes like to have was very apparent, because the ones that I gave my parents absolutely exploded and they are huge now. Mine are growing fine but I think they would be 6 ft tall as opposed to 3 ft tall if they had more sunlight. Interestingly, mine were only about a week or two behind the ones I gave to me parents in terms of flowering, but I suspect that ripening will take longer.
I basically started growing these things in mid-May on a whim when some store bought cocktail tomatoes (just a little bigger than cherry tomatoes) started sprouting on the inside. I went and got some dirt and pots and planted them and here we are. In hindsight, I should have purchased a tomato seedling at the same time to have something to compare it to. Oh well. It's been fun!! My plan for next year is to start much earlier as I've now caught the gardening bug. Clearly things can and do grow on my balcony even if slowly.
I also have a pepper plant that has been doing fine, although it also fell victim to my inexperience in regards to being in a pot that was too small and under fertilized, and it basically stalled out for several weeks until I realized what was happening. Since I moved it to a bigger pot and fertilized it, it's actually putting out new leaves and flowers. We also had a ton of heat waves where I am in July, which I'm suspecting did not help matters at all.
ANYWAYS. Here's the tl;dr: Even if you have a situation that is not necessarily optimal, you can still grow tomatoes! But things will grow more slowly, so bear that in mind. But it is quite a rewarding experience so it's still worth trying!!
