Pruning the plants while they're young will allow you to help shape how they grow. Once the herbs have a full set of leaves, they're old enough to be pruned. For many herbs, you can begin pruning them once they're roughly 6 inches (15cm) tall. Pruning your herbs will make them sturdier, allow them to grow more leaves, and prevent them from becoming too bushy or top-heavy. Locate the spot where the branches and leaves meet the main stalk. Use clean scissors to make a cut right above the set of leaves. This cut will allow 2 new stems to grow from that spot, giving your plant more volume. You can use your fingers to prune delicate plants. Make sure you don't rip off stems, as this can lead to disease. This will leave a solid base for the plant to grow from. You can trim the plant right above the 1st or 2nd set of leaves when pruning the side stems that will grow from that initial cut. This is an especially helpful way to grow herbs like basil abundantly. Thicker herbs like thyme, rosemary, and sage don't need to be pruned very often unless you want to harvest them frequently. Simply pruning them when you see dead leaves or at least once a year should be enough. Woodier herbs are herbs with hardier stems and leaves, as opposed to delicate herbs with thin stems like basil or cilantro. Try to always prune away leaves before they start to flower. Removing flowers will redirect the energy into leaf production. Remember to prune right above a set of leaves.
Prune your herbs in their early stages. Make your cut right above where the branches intersect the stalk. Cut above the 3rd set of leaves the first time you prune. Trim woodier herbs roughly once a year. Remove flower buds from herbs when you first see them.
