One is to cut the plant near the ground and let it regrow from 2-inch-long stems.
Prune it now or just before new growth begins. Another method to reduce its size requires more care. Trace the longest branch of the shrub inside the plant and remove it where it joins a main branch.
Leave no stub. Select two or three other long branches on the inside and make the same kind of cuts. Prune every couple of years or when it gets too large.
After pruning, fertilize as you would to encourage new growth. One fertilizer application a year is all that is needed unless you are growing it as an herb that requires frequent harvesting. Applying too much fertilizer will dilute the oil content and fragrance. If you are harvesting frequently, fertilize lightly every 6 to 8 weeks with a balanced fertilizer containing nitrogen and phosphorus.
