Rosemary does well in containers in a soil-based, peat-free compost. Add crocks to the bottom of pots to aid drainage. Keep rosemary plants well watered during dry spells and feed with a general fertiliser during the growing season. In cold winters, bring plants under cover.
Care: If the top 1 to 2 inches (3-5 cm.) of soil feels dry, it’s time to water. Water the plant deeply, then let the pot drain freely and never let the pot stand in water. Use care, as overwatering is the most common reason rosemary plants don’t survive in containers.
