<human>:  How do I prune tomato plants?
<bot>: To prune tomato plants, start by removing any dead or damaged branches. Cut off branches that are growing in towards the center of the plant. Cut them back to the nearest leaf branch. Then cut off any straggly side shoots, making the cut at a 15-degree angle just above a leaf. Prune leaves and branches that shade the fruit and flowers, as well as any branches that are too close together. This will allow more air to circulate and let the sun reach all of the branches.
