Pinching and topping refers to the removal of the top part of a plant. Pinching peppers results in more side branches and a bushier plant which, it is claimed, leads to more fruit and a higher yield. Is this true? Should you pinch pepper plants?
Some people also suggest removing the first bloom to allow the seedling to grow larger and develop a better root system. Does this really happen? Does it increase yield. Should you pinch the first bloom?
There are lots of opinions online and in blog posts, but I found none that actually presented any scientific evidence for their suggestions. What does science say?
