I almost never top pepper plants (I used to, though). The ensuing over-bushiness and low branching that forces new shoots (and subsequently, pods) to grow in contact with the mulch and rain splash create nothing but problems with rotten pods, foliar disease and insect damage.Â
   I prune my plants so that they (depending on the variety) have no branching below about 4-8" above ground level. Sure this means that my plants will have to wait an extra week or two before they really start to bush out, but it all comes out in the wash. Pepper plants are going to bush out and produce lots of pod-bearig shoots - if a plant is healthy, it will do this regardless of any tinkering on behalf of their grower. A plant that isn't topped just happens to produce its bushy, pod-producing growth a little further above ground than a topped plant - simple as that. Â

   I didn't link to my glog to to show you that is this is the only way to prune your pepper plants, just to give you an idea of what the other side of the coin looks like. My plants' canopies are all (pretty much) safely out of harm's way of rainsplash and slugs that want to crawl up leaves and pods that are dragging on the ground. Also, lifting the plants' crowns off the ground facilitates airflow under and through the plants' canopies. This allows rain and dew to dry off the plants a lot faster than if they were all bushed out at ground level. The less time a plant spends with wet foliage, the less of an opportunity foliar pathogens have to get a foothold.Â
   Last and not least, when a plant is young, the nodes on it's central stem are very close together. When a plant is topped, all the new shoots are forced to grow from this clusterf**k of nodes all right next to each other on the main stem. As stated above, this impedes airflow through the plant. Also, all those crowded side shoots have to compete with each other when they all originate from the same place at the same time. This leads to weak, leggy growth with poor attachment points to the main stem. This is a recipe for branches that bend down to soil level, or worse, break off altogether.
   Maybe a topped plant produces more pods sooner, I dunno. Mine never did. My less drastically pruned plants have produced a metric shit-ton so far this year, with no signs of slowing down. Maybe if I had topped them I would've gotten a pods a week or so sooner. But the amount of lost pods due to BLS and slug damage that could have resulted from topping probably would have negated any gains.
