Best Rosemary Varieties for Hedges

The best rosemary hedges are made from rosemary cultivars that grow in an upright form.

Some rosemary cultivars, on the other hand, have a cascading or creeping habit such as ‘Roman Beauty’. These cultivars are better suited for growing in a rock garden or on top of a wall or balcony.

Some of the best upright growing rosemary cultivars that are best for hedges include:

  • Tuscan Blue
  • Lady in White
  • Majorca Pink
  • Miss Jessopp’s Upright
  • Spice Islands
  • Blue Spires

Planting Rosemary

Choose a site that is slightly sheltered in full sun in hardiness zones 8 to 10. Be sure to check the hardiness zone of the cultivar you are planting so that your hedge will survive your worst winter weather.

Prepare the site by ensuring that it is weed free, and the soil is loose and well-draining. Rosemary tolerates poor soils, even sandy gravel.

Create a beveled edge or install edging to help keep the hedge weed and grass free while it grows in. This will also minimize future maintenance, having a nice edge to mow or trim up to without damaging the hedge.

Dig holes for each plant at twice the size of the root ball. Snug each plant in place with soil and tamp it down.

Space each rosemary plant 50cm apart for a lighter hedge and space 35cm apart for a denser hedge.

Keep the soil damp for the first few months while the plants become established. Once they are established, water thoroughly in the fall to enable the plant to protect itself through the winter months.

Apply an ample layer of compost or bark mulch around young rosemary plants. This will help conserve moisture, suppress weed competition, and it also looks stunning!

Sourcing Rosemary Plants

Rosemary can be propagated from seed or cuttings. Seeds take a long time, 14 to 21 days, to germinate, but this can be a cost-effective way to grow many rosemary plants for a hedge.

Alternatively, cuttings can be taken from young healthy stems and rooted in water. Once they are rooted, they can be transferred into pots with potting soil where they can grow on until planting time.

Either way, propagating rosemary yourself can be a fast and cost-effective way to produce many plants for a future hedge.

Here’s a tutorial for propagating rosemary cuttings which enables you to grow lots of plants for free.

Another less expensive way may be to talk to your local nursery. They may be willing to start seedlings for you of your desired rosemary cultivar.

Buying seedlings rather than mature potted plants may be a low-cost way to accumulate many plants for a long, gorgeous hedge.

Put your hedge on high-speed by purchasing ready-to-go potted plants. This will shave off a few seasons of waiting to see your fragrant, full-grown hedge in its mature glory.

Caring for Your Rosemary Hedge

Mimicking the natural environment to its native growing conditions of the Mediterranean seaside is a sure way to have success growing rosemary. That is to say, warm, dry, and well-draining soil.

For companion planting, rosemary’s friends in the garden include sage, lavender, carrots, cabbage, and beans.

Enemies of rosemary are poor air circulation, high humidity, and heavy, damp, clay soils. These conditions may lead to diseases such as powdery mildew, botrytis, and root rot.

Insect pests are rarely a problem for rosemary growing outdoors in optimal conditions but may bother unhealthy plants. Keep an eye out for whiteflies, aphids, mealybugs, and spider mites.

Pruning and Shaping

Rosemary takes well to pruning and shaping. It helps the plant develop bushier, healthy growth as well.

Always use sharp clean pruners, scissors, and shears for healthy cuts. And make sure you don’t throw away the cut off leaves and stems – they can be used in so many brilliant ways.

The best time to prune and shape is after the plant has flowered in the spring. Remember that rosemary blooms on last year’s wood, so pruning in the fall or too early in the spring may remove the spring’s blossoms.

Here’s our total guide to pruning rosemary for healthy bushy plants.
