Can you transplant tomato plants?

No definately not..they are at the fruiting stage and all thier energy is going to fruiting..If transplanted this mature they will not be focussed on rooting..and if the roots dont die..they will fall over from the weight no matter how well staked...but if you would like clones....you can take cuttings fron any sucker leaf....put some root stimulator on the cut part...put in a gl of water for 2 or 3 days untill you see roots forming...then plant in soil...make sure to bury 80% of this plant..it makes strong plants...When I buy settings, I pull all the leaves off to the top 3 sets..and plant the whole stem..the fuzzy stuff you see on the stems..will all turn to roots....heres a link to my veggie garden..picture titled 'garden pc 008" the very furthest plants are all tomato plants I took cuttings from the "mother plant"..do not transplant plants in maturity...they will die!
