OK, experiment that may have gone awry.
Taking seeds out of a tomato, including some of the juice and bits and planted. This is the huge batch of plants I had.
Somebody warned on YouTube it would create diseased plants. Well, there was basically no cost except a small amount of time so let’s go.
OK, there’s 3 dozen of these things - growing like weeds. BUT the leaves on all of them (most of the leaves) are showing patches of yellow, with brown spots and even holes.
Obviously something is wrong. I can reuse the dirt if I have to pitch them. Just transplanted to better soil. Still have some bone meal. But I have others planted likewise (starter seeds).
Pitch? Or is there any hope?
About all I can contribute is I have been saving tomato seeds for more years than I can count. I never plant them fresh however I dry them on a paper towel and save for the next year. I always have healthy beautiful productive plants. The seeds do stick to the paper towel but you can plant the paper towel as a sheet if you like or cut up, he paper bits break down quickly.
I have no idea. I’ve never grown tomatoes from ‘wet’ seed before.
Yellowing leaves are a nutrition issue...if you didn’t start fertilizing the seedlings when they had their first set of ‘true’ leaves, then that may be the issue.
Brown leaves are either disease or bad watering practices.
Really can’t tell without seeing the plants. How much longer is your growing season? Do you have another 90+ days to grow these to maturity?
