If you have not removed any suckers all season and they have grown out of control, you should be careful about taking off the entire sucker, as it could cause too much sun to hit the developing fruit. In this case remove parts of the sucker to the last set of leaves. This is called Missouri pruning, where you pinch just the tip of the sucker, letting one or two leaves remain. This gives the plant more leaves and thus more photosynthesis and aids in protecting developing fruit from sun-scald. In this case, suckers should be removed gradually, over a period of a week or more, so the plant is not shocked too much.
Thanks, being from Missouri I was wondering about that.
Thank you muchly. My son told me I should be removing the suckers, but I wasn’t really sure what they are. Missouri pruning makes sense too
