Do Lavender And Heather Grow Well Together

Lavender and heather can grow well together when their specific soil, sunlight, and drainage needs are carefully matched.

It’s a pairing that looks absolutely stunning in a garden, with those soft purple spires of lavender rising above the low, textured mounds of heather.

But the truth is, these two plants aren’t always the easiest of companions, and whether they thrive together depends entirely on the varieties you choose and the conditions you provide.

In this post, we’ll dig into the details of why lavender and heather can grow well together, the potential challenges you might face, and how to set up a planting scheme where both plants can truly flourish.

Let’s explore this beautiful partnership.
 
## Why Lavender And Heather Can Grow Well Together
The key to understanding if lavender and heather grow well together starts with their origins.
 
Lavender comes from the hot, dry, rocky hillsides of the Mediterranean, while heather is native to the cooler, often damp, and acidic moorlands of Europe.
 
They have very different natural habitats, so getting them to coexist is about finding common ground.
 
### 1. They Both Crave Excellent Drainage
One of the most important reasons lavender and heather can grow well together is their shared hatred of soggy roots.
 
Both plants are incredibly susceptible to root rot if they sit in waterlogged soil for too long.
 
So, when you plant them together, the absolute first priority must be creating a planting bed with sharp, fast-draining soil.
 
If you can achieve that free-draining environment, you’ve already overcome the biggest hurdle to making lavender and heather grow well together.
 
### 2. They Both Love Full Sun
Another reason lavender and heather can grow well together is their mutual preference for bright, open positions.
 
Both plants will produce more vibrant foliage and a heavier flush of flowers when they receive at least six hours of direct sunlight per day.
 
A sunny, open border is the perfect stage for this duo, providing the light energy they both need to thrive.
 
### 3. They’re Both Low-Maintenance and Drought-Tolerant
Once established, both lavender and heather are wonderfully low-maintenance plants.
 
They don’t demand rich, fertile soil, and they rarely need additional feeding, which makes them ideal for a relaxed gardening style.
 
This shared resilience means that, aside from an annual trim, you can largely leave lavender and heather to get on with things.
 
Their drought tolerance also means they can grow well together in areas where you might forget to water them regularly.
 
## The Challenge Of Soil PH With Lavender And Heather
While they have some great similarities, the biggest issue that prevents lavender and heather from growing well together is their conflicting soil pH requirements.
 
This is the crucial detail that most gardeners overlook.
 
Lavender prefers alkaline to neutral soil, with a pH between 6.5 and 7.5, while heather absolutely demands acidic soil, typically with a pH between 4.5 and 5.5.
 
Planting them directly next to each other in the same earth will cause one of them to suffer.
 
If the soil is acidic to please the heather, the lavender will become weak, yellow, and more prone to disease.
 
If the soil is alkaline to suit the lavender, the heather will quickly decline and fail to thrive.
 
This is the fundamental reason why you can’t just assume lavender and heather will grow well together in any old border.
 
### How To Overcome The PH Problem
The solution is to grow them in separate containers or to create distinct planting pockets within the same bed.
 
You can sink a large pot into the ground to contain the acidic soil for your heather, while the surrounding alkaline soil is perfect for your lavender.
 
This strategy allows both plants to grow well together visually, but keeps their root systems in the soil they each prefer.
 
Another option is to plant your heather in a raised bed filled with ericaceous compost and plant your lavender in the ground nearby.
 
By creating separate soil zones, you can successfully make lavender and heather grow well together in the same garden space.
 
## Selecting The Right Varieties For Companionship
Choosing the correct species is essential if you want lavender and heather to grow well together in a more natural, mixed planting.
 
There are some varieties of heather that are more tolerant of neutral soils than others.
 
### 1. Choose Tolerant Heather Types
For example, winter heathers (Erica carnea) are far more tolerant of alkaline and neutral soils than summer-flowering heathers (Calluna vulgaris).
 
Erica carnea will happily grow in soil that suits lavender perfectly, making this the ideal partner.
 
By choosing this specific type of heather, you can successfully let lavender and heather grow well together without any soil amendments.
 
### 2. Match The Size and Habit
It’s also wise to match the growth habits of your chosen plants.
 
A compact, mounded lavender like ‘Hidcote’ or ‘Munstead’ pairs better with dwarf heather varieties.
 
This ensures that neither plant overwhelms the other, so they can grow well together in a balanced composition.
 
## Caring For Your Lavender And Heather Combo
Once you’ve sorted out the soil, helping lavender and heather grow well together is simply a case of adopting the right care routine.
 
Remember that these are not thirsty plants and should never be overwatered.
 
Only water deeply during prolonged dry spells while they are establishing.
 
You should also avoid using any general-purpose fertilizers, as these can harm the sensitive root systems of both plants.
 
When it comes to pruning, simply trim back the heather in early spring after flowering to keep it neat.
 
Prune your lavender in late summer after its main bloom has faded to maintain a woody, compact shape.
 
Following this minimal care routine will go a long way in ensuring that lavender and heather grow well together for many seasons.
 
## So, Do Lavender And Heather Grow Well Together?
Yes, lavender and heather can grow well together, but it requires a little bit of planning and a good understanding of their needs.
 
They can grow well together because they share a love for sun and well-drained soil.
 
However, they can only truly flourish together if you address their conflicting pH needs, either by choosing a tolerant variety like Erica carnea or by planting them in separate containers.
 
With these considerations in mind, you can create a stunning, textured display that brings the best of both worlds to your garden.
 
So, the answer is a confident yes, as long as you are prepared to manage the soil conditions correctly.
 
Happy gardening.
