heatherWhat is Ericaceous Compost?

You will probably have heard of ericaceous compost in terms of what you can grow in it. It is an acidic compost, and suitable for growing rhododendrons, camellias, azaleas, heathers, and other plants that dislike alkaline soil, also known as lime-hating plants. The name ‘ericaceous’ comes from the Latin name for heathers, Erica.

 

Our ericaceous compost has a pH balance which is perfect for growing acid loving plants including blueberries, azaleas, camellias, rhododendrons, and heathers. The increasing popularity of blueberry bushes in our gardens and tomatoes in our greenhouses have made this one of the most widely-used and trusted specialist composts on the market. Whether it’s juicy superfoods or the vibrant, striking colour of acer trees, the delicate beauty of camellias, or the hardy, year-round charm of checkerberry, Ericaceous soil improvers offer your garden a healthy dose of low-ph goodness to keep your favourite specimens thriving.

Ericaceous compost facts 

Ericaceous plants needs to live in the correct soil for their vitamin needs- while lime-rich, high pH (alkaline) soil tends to bind the iron and other nutrients essential for healthy growth. Plants that need nutrients which are inaccessible in high pH soil are known as acid-loving (or lime-hating). If planted in normal, limey or alkaline soil,Ericaceous plants produce weak, yellow leaves and generally perform poorly.

Ensuring your Ericaceous plants perform well can be a challenge in the wrong soil. While long-term changes to neutralise alkalinity are possible, most gardening experts recommend planting your Ericaceous plants in an isolated pocket of acidic soil, using high quality topsoil and compost designed especially for this role. With the right specialist soil & compost, even the most demanding Ericaceous plants can thrive.

There are several ways to test your soil pH- for the most reliable results we recommend using a specialist kit.

We only stock Ericaceous Compost from reliable, tried & tested suppliers- and all our stock has been thoroughly tested on our own farm! We won’t sell a blend until it’s impressed us- and we’re satisfied its production surpasses high ethical standards.

 

Ericaceous compost gets amazing results because it allows the release of those vitamins, such as iron, needed most by acid-loving plants. These essential vitamins can be bound up in the structure of normal soil, depriving the roots of your plants and resulting in stunted, unhealthy growth that can leave you exasperated.

When to Use Acidic Compost

You use ericaceous compost when the soil in your garden is too alkaline to grow lime-haters. And how do you know the pH of your soil? Well, you can either look at your neighbours’ gardens to see if they’re growing rhododendrons, or you can buy a soil-testing kit and test the pH for yourself. If the pH is above 7.0, then you will probably need to grow your ericaceous plants in pots, and in ericaceous compost. Although you can add chemicals to increase the acidity of your soil, you probably won’t have much long-term effect, especially if your soil is very alkaline. And some plants are so strongly ericaceous that they won’t grow in even slightly alkaline soil. Rhododendrons and azaleas are more tolerant, but blueberries like a pH of less than 5.5, so need to be grown in pots in ericaceous compost in much of the UK.

Where to Buy Ericaceous Compost

Ericaceous compost is widely available from garden centres and compost suppliers. The Royal Horticultural Society recommends loam-based ericaceous compost such as John Innes Compost, but says that peat-free ericaceous composts are improving all the time, and will be perfectly suitable. 

You can grow a wide range of plants in pots, even quite large shrubs such as camellias, provided you choose the right pots. Dwarf rhododendrons, such as the Rhododendron yakushimanum hybrids, are really good pot plants. They flower reliably, year after year, and remain small. There are also some lovely dwarf azaleas available that are perfect for pot cultivation. Camellias can get a bit big, but choose carefully, and you could even have one of those. As with all pot cultivation, you need to choose a pot that is not too much bigger than the pot your plant is currently in, or the soil will go sour before the roots have spread into it. You need it to be about two inches bigger than the rootball all the way round. If you want to use a much bigger pot, then put several plants in it.

Whatever ericaceous compost you choose, your plants will need repotting every couple of years, as the compost will lose its structure and nutrients over time. This will give you a chance to move your plants into bigger pots if necessary, or prune the rootball if you want to keep them small. Your plants will also thank you for feeding them with ericaceous fertiliser in the spring when they start to grow again.
