Where to Buy Westringia ‘Wynyabbie Gems’?

You can find young plants grown from cuttings in plant nurseries.

However, you can easily find these plants online if you don’t see any Westringia ‘Wynyabbie Gems’ in your local garden center or a plant sale outlet nearby.

How to care for Westringia ‘Wynyabbie Gems’?

Now that you know a great deal about Westringia ‘Wynyabbie Gems’, it is time to look at how to care for the plant.

1. Sunlight

Westringia ‘Wynyabbie Gems’ prefer full to partial sun.

If you grow them outdoors, provide them with 6–8 hours of full sun.

On the other hand, if you grow them indoors, it will be best to provide them with 4–6 hours of partial to full sunlight.

However, please ensure not to scorch the plant as it prefers a slight shade. However, the foliage will become less dense if you plant it in a significantly shady place.

Keeping these guidelines in mind, east and south side windows will work best for an indoor plant pot.

2. Soil Type

If you are planting it in a pot, ensure that the potting mixture is well-draining.

Westringia ‘Wynyabbie Gems’ prefer sandy, loamy soil.

A well-draining soil can prevent a lot of plant problems. One of the biggest problems in Westringias is wet feet which can be prevented by using well-draining soil.

3. Watering

As it is a drought-tolerant plant, Westringia ‘Wynyabbie Gems’ can survive short periods of underwatering.

However, if extended, underwatering can harm the plant.

It would be best to water the plant moderately throughout the year. Let the soil dry in between watering—water only when the soil is entirely dry.

You can poke your fingers into the soil to feel the moisture or use a moisture meter. If the soil feels moist, wait for it to dry before giving it another shot of hydration.

Water more when the plant is exposed to extreme heat.

4. Humidity

Westringia ‘Wynyabbie Gems’ are pretty hardy plants. They can survive low to high humidity levels.

However, if you want a number, try to keep the moisture levels around 60%.

5. Temperature

It is also a winter hardy plant.

Westringia ‘Wynyabbie Gems’ can survive frost down to -6°C. Its winter hardiness is mostly mentioned as 20–25°F.

Westringias grow best in warm Mediterranean climates with an average temperature of around 20°C.

If you grow this plant outdoors, the night temperature should ideally be above 20°F.

6. Fertilizer

Now, let us talk about fertilization.

You can fertilize this plant once a year during spring with slow-releasing organic fertilizer. Moreover, you can provide the plant with a mineral fertilizer every month in dilute form.

You can also add compost to your potting mix to increase its nutritional content.

7. Pruning

To maintain their size and shape, you can prune these plants after the blooming season.

Pruning the plant will keep it in a more compact body or hedge.

Westringia ‘Wynyabbie Gems’ respond well to pruning. Regular pruning will yield neater, denser foliage.

Pruning the tips after flowering has ended encourages vigorous growth. Tip pruning is essential to prevent wind damage and collapsing of the plant if it becomes too heavy on top.

Cut out old growth from the center of the plant every few years to encourage new shoots in the middle.
