Apply the fertilizer to the soil around the plant, and water thoroughly to allow the nutrients to penetrate the soil.
Pruning
Pruning is not necessary for Orthosiphon thorncroftii N.E.Br., but you can trim the plant in the fall to maintain its shape and promote bushier growth. Cut back any damaged or old branches to encourage new growth. The plant can also benefit from deadheading, which involves removing spent flowers to promote plant growth and prolong its blooming season.
