Although I don't have nearly as many tomato planst as some of you experts out there.. I'm kinda proud of my lil guys since this is only my second year of gardening...
I started most of my tomatoes using the large expandable peat pllets and Jiffy mini greenhouse trays. Just re-potted last weekend into peat pots. I read the posts regarding NOT to plantthe peat pots into the ground. I agree! Did that last year and I think it hindered my overall veggies.
I mixed my own soil for re-potting. Regular potting soil, organic compost and seed starting mix. I just kinda mixed them together until a semi fluffy mix occurred. If all goes well, I should have 70 tomatoes.
