Care Guide
Watering Rosemary
Allow the soil to dry out completely between watering sessions. Rosemary hates soggy soil and root rot easily develops if overwatered. Water deeply, then wait until the top few centimeters of soil are dry before watering again.
Sunlight Requirements
Place rosemary in a location that receives at least six to eight hours of direct sunlight daily. Insufficient light will lead to leggy growth and reduced essential oil production.
Soil and Fertilization
Plant in sandy, rocky, or well-draining soil with a neutral to slightly alkaline pH. Fertilization is rarely necessary; a light application of balanced organic fertilizer in spring is usually sufficient.
Pruning and Maintenance
Prune rosemary lightly after flowering to maintain a bushy shape and encourage fresh foliage growth. Avoid cutting back into old, bare wood where new shoots may not emerge.
Propagation Methods
Cutting
Take a 10-15 cm stem cutting from healthy new growth, strip the lower leaves, dip in rooting hormone, and plant in a moist, sandy soil mix until roots establish.
