I am trying organic gardening. No matter if I direct sow outside or if I start them indoors, my tomato seedlings decide to take a break from growing at about 2 inches for weeks. When I direct sow, they sprout reliably, and do very well at first, but then pause and won't start really growing until they are at least a month old and if I start them indoors, earlier in the season the they refuse to get any bigger until I plant them outside and then wait for mid-summer to start growing. As usual at this point in the season, my tomatoes are now only a foot tall. Every year, I get a small handful of tomatoes and throw out a whole bunch of little green marbles in October. I purchase only heirloom seeds and have tried many different vendors and varieties. Is it weather? Direction? Soil? Please help. Any and all advice is welcome. I just had a thought; it seems like they pause at their 3rd set of true leaves. Does that mean anything? Thanks in advance.
