How to Grow Westringia

Young and healthy plants can be purchased from reputable local nurseries or westringias can be propagated using cuttings. It is not recommended to try growing them from seeds as this is not a reliable way to ensure the quality of the species or cultivars.

Westringia Propagation

Westringia Propagation

Propagating Westringia Using Cuttings

  • Select healthy young stems to take cuttings from.
  • Using sharp and sterile garden shears, take a cutting by snipping below a leaf node on your stem and remove the foliage from the bottom two nodes.
  • It is recommended to take multiple cuttings as there might be some losses along the way. 
  • Place your cuttings into well-draining containers or growing trays filled with a potting mix of 90% perlite and 10% peat moss. The sections of the cuttings that were stripped away should be placed into the soil mix.
  • Water well after planting and keep your propagation mix lightly moist at all times being careful not to let it dry out. 
  • Place your cuttings in a well lit but sheltered location away from direct sunlight or strong winds. 
  • Roots will start to develop in around two to three months depending on temperatures. 
  • Once your cuttings have good healthy root development you can plant them as desired in organic soil rich in nutrients. 

It is important to note that these plants can struggle to establish themselves in cooler climates so be patient and you should have a healthy plant in no time.

How to Plant Westringias

Planting Westringia in the Garden

  • Choose a spot in your garden that gets full sun to part shade.
  • Dig a planting hole twice as wide and to the same depth as the root ball. 
  • Gently remove your plant from its current container and lightly tousle the roots with your fingers to remove old soil. Try disturbing the roots as little as possible.
  • Gently position your plant in the hole and slowly backfill with your soil. Lightly firm the soil around the plant with your palms being sure not to overly compact it. 
  • Water well after planting to settle the soil around the roots.
  • Mulch around but not too close to the base of the plant with organic mulch.
  • Keep the soil moist for several weeks to help the plant establish itself. 
  • You can optionally add a native fertiliser occasionally to ensure strong root development.

Planting Westringia in a Container

  • Choose a pot or container that is well-draining and at least twice the size of your plant. 
  • Fill your new container with a quality potting mix and dig a hole at least twice the size of the root ball.
  • Carefully remove your plant from its current container being sure to disturb the roots as little as possible. 
  • Position in your hole and backfill with your potting mix. 
  • Gently firm down and water in well. 
  • Mulch around but not too close to the base of the plant with organic mulch.
  • Keep your soil lightly moist but not waterlogged.

How to Care for Westringia

Once established, these plants are tolerant to cold, drought and moisture but they do not enjoy long exposure to freezing temperatures or icy winds. Overall, these natives are especially low-maintenance and easy-going in Australian gardens.

Watering Needs

Water to keep your soil slightly moist but not wet as these plants don’t like sitting with wet feet. They generally have low water needs so be careful not to overwater as this can lead to root rot issues. 

Pruning Westringias

These plants will respond best to light pruning done during spring to early summer. Try only cutting back soft, leafy growth and not too much hardwood.

Hard, vigorous pruning can lead to stunted growth so this should be avoided as much as possible. For westringia hedge pruning, a frequent but light routine is great to keep tidy and encourage denser growth.

What Fertiliser to Use

Though not necessary, you can feed your plants annually in early spring with specifically designed native plant food or an organic-based fertiliser.

Common Pets, Problems & Diseases

Westringia are rarely affected by pests or diseases

Luckily, these natives are rarely affected by pests or diseases. The only issue that is common with these plants is overwatering which can quickly lead to root rot.

You will know your plant is suffering from root rot if the roots start to look black and feel mushy. Healthy roots may still appear dark or pale but they will feel firm and pliable to the touch.  

To treat root rot, you can clean the roots under running water and then gently remove the affected areas of the root system. Discard your old soil and replenish your bed or container with fresh organic soil.

Wash your pots and equipment and water your plant well. It should be able to recover soon with some extra care. 

Westringia Frequently Asked Questions

Are westringia roots invasive?

The westringia root systems are regarded as non-invasive and safe for planting near paved or built-up areas. 

How tall do westringias grow?

On average, these plants grow to around three metres tall. There are naturally taller growing varieties as well as a few dwarf varieties to choose from. 

Why is my westringia going yellow?

This could indicate that there is too much phosphorus in your soil which can poison many native plants. If the leaves of your plant are yellowing, this could also indicate that your soil is deficient in iron or that the pH balance is incorrect.

In severe cases, use soil testing kits to see how you can improve your soil quality.
