I'm new to vegetable gardening and am going to try tomatoes, potatoes, cucumbers, corn, carrots and iceburg lettuce this spring. I'm in Texas. Our last spring frost date is March 16th which is about 6 weeks away. I started my tomatoes and lettuce in containers yesterday so that they will be ready to be transplanted by March 16 (or very soon after). Here is my question. I have done plenty of my own research on this subject but have come up with nothing. If the tomatoes and lettuce have 6 weeks to grow in containers, is that too long? I cant find any info on how many weeks they should stay in the containers before transplanting, just things that say "transplant when lettuce has 2 true leaves". How long does that take?? If the 2 true leaves are developed in week 3 (just an example, this can go for any container veggie) but it is still too cold outside to transplant, is it okay for them to stay in the containers a few more weeks? I know the lettuce absolutely has to be transplanted but can the tomatoes stay in the pots as long as they are getting full sun, lots of water, etc? I already have all the other veggies that are going in the ground, it would be nice to keep one or maybe 2 in containers. Thanks for any advice you can give.
