re: Question about low tomato production

First, you probably could have started the seeds earlier, but it’s likely not the only issue. I had a similar problems last year and this year got much better results.

First thing with tomatoes is they don’t need much nitrogen. Use a balanced fertilizer, and I added a little extra phosphorus at planting and during fruiting, just to make me feel better. Avoid overwatering, it rinses the fertilizer out prematurely and makes it hard to keep up.

Leave the plants if you want, if they look healthy then there’s not much reason to pull them. Good chance something will get them between now and fall though, so be prepared if you want a shot at a fall crop.
