Rosemary is a versatile herb, providing evergreen interest all year round, fragrant leaves for use in cooking, and nectar-rich flowers for bees in spring. Grow rosemary along a path, so every time you brush past, the leaves release their aromatic oils.
Hailing from the Mediterranean, rosemary thrives in a sunny, sheltered spot in well-drained soil. It can struggle in heavy clay soils, particularly in winter, when the ground tends to be wetter. You can grow rosemary in pots, but bear in mind this perennial herb can grow quite big, and will need potting on in fresh compost every couple of years.
How to Grow Rosemary Plant
When to Plant
Rosemary is best planted in the spring once the weather has warmed and there’s no frost in the forecast. Containers indoors generally can be started at any time of year.
Selecting a Planting Site
This plant needs a sunny spot that has soil with sharp drainage. Make sure no taller trees or shrubs in the area are so close that they will shade the rosemary. Rosemary also grows well in containers both outdoors and indoors, as long as it can get enough light.
Spacing, Depth, and Support
Space rosemary shrubs at least 2 to 3 feet apart. Plant seedlings and nursery plants at the same depth at which they were growing in their previous container. Seeds should be just barely covered with soil when planting. A support structure is typically not necessary for this shrub.
Caring for Rosemary Plant
Rosemary requires little maintenance during the year except cutting back after flowering to prevent plants becoming straggly and woody. Save the trimmings to propagate new plants or dry them for cooking.
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 for protection.
How to Fertilize Rosemary Plant
It’s best to only fertilize rosemary during the growing season that starts in the spring. Follow the instructions on your favorite fertilizer and continue once a month or so through fall. If you’re keeping an organic garden, make sure to use organic fertilizer.
