Plucking away one basil leaf at a time can cause the plant to become tall and thin and eventually topple over. Luckily, there is a trick to harvesting without stunting its growth.
When plants have reached at least 6 inches tall, prune regularly by snipping the main stem above the nodes on the upper leaves, allowing the lower leaves to keep growing.
Frequently harvesting and correctly pruning your plant won't just keep it alive longer, it'll encourage your basil to grow fuller, bushier, and healthier all season long.
