I grow my tomato plants in pots, on the deck. The deer have a nasty habit
of eating if I grow them in the ground.
One of my plants is reaching 7' tall, it is the grape variety. I don't have
cages or anything around them, just 6' stakes. They are in 15 gallon pots.
Can I just prune the top, so it doesn't grow any taller? I don't want to
kill the plant, just wondering if this will end the growth for the height.
