pruning tomatoes #755413

Asked June 10, 2021, 6:20 PM EDT

I have staked my tomatoes (6 plants) using 1 x 2 inch stakes which I dug in the ground about 18" deep before planting the tomato plants. The stakes are about 6' tall sticking out of the ground. I plan to tie the tomatoes to the stakes as they grow. I know what the suckers are and have been removing them as the plants are growing, but wondering if you are suppose to remove all of them all the way up the plant as the tomato grows. Or do you stop at some point on the way up the main stem? I have been taking them off, but it seems like the plant would be looking very thinned out if I did it all the way up. Can you help me? I have rented garden space at Bloomington Community Gardens. Thank you so much! Mary Ann

Expert Response

It really depends on whether the plants are determinate or indeterminate.   The rationale for pruning is explained in website one.  Website two explains determinate/indeterminate. I am guessing that yours are indeterminate because of the staking. Website three gives additional information if you don’t know what your varieties are.
