Can You Use Ericaceous Compost For Eucalyptus?

Ericaceous plants, also known as “lime-haters,” are special plants. This means they have difficulty flourishing in soils with a pH above 6 since they require an acidic environment to thrive.

Because of this, their leaves will gradually turn yellow, and they may even perish if they cannot get the nutrition they need.

What is ericaceous compost, and why do you need to apply it if you’ve just brought home a gorgeous plant from the garden center?

In this post, we will acknowledge whether can you use ericaceous compost for eucalyptus and how to utilize it in your garden.

What Is Ericaceous Compost?

Ericaceous compost, so called because it is more acidic, is named after the Ericaceae family of plants, which thrive in such soil. These plants prefer an acidic compost since they cannot tolerate lime.

Feeding plants with ericaceous compost helps them thrive in acidic conditions. Azaleas and blueberries are two examples of acid-loving plants that struggle in alkaline soil.

Soil acidification from ericaceous compost can also encourage blue flowers, in particular hydrangea species (more on this later).

The acidic pH of ericaceous compost is below 7.0. Ericaceous compost can acidify the soil, making plant-useful nutrients more readily available.

The ability of a plant to take up nutrients through its root system depends on the availability of those nutrients in the soil.

The plant’s roots won’t be able to take in the nutrition if the soil pH is too high or low. Although there may be an abundance of a given nutrient in the soil, plants may be unable to use it if the soil’s pH is too high or low.

Can You Use Ericaceous Compost For Eucalyptus?

Yes, you can use ericaceous compost for eucalyptus.  Eucalyptus can be composted with ericaceous materials. Ericaceous compost provides the acidity, organic nutrients, and well-drained soil that eucalyptus requires to flourish.

With the right amount of ericaceous compost, your eucalyptus plant can flourish, whether growing a neatly manicured shrub indoors or trying to allow a tree to reach its full potential outside.

Ericaceous compost can be used for a wide variety of garden purposes. Your rhododendrons and camellias will flourish in this rich, loamy compost.

Depending on the ingredients, ericaceous compost can have a lengthy shelf life (potentially years). Peat moss, for instance, can stay in the ground for years without becoming compacted.

Only amend soil after first determining its pH and nutrient levels. If you add far too much acid to the soil at once, it can kill the plants.

To make matters worse, you might have to add lime and other adjustments to bring the pH level back up to where it should be.

How To Make Compost Acidic?

Making compost with acid-loving plants is quite similar to making regular compost, albeit there is no “one size fits all” ericaceous compost recipe because it depends on the present pH of each particular pile.

You should put a layer of organic material between 6 and 8 inches (15 and 20 cm) deep at the bottom of your compost pile. But there’s no lime juice involved. However, lime has the reverse effect; it raises soil alkalinity rather than soil acidity.

Utilize high-acid organic matter like oak leaves, pine needles, and coffee grounds to increase the acidity of your compost. Pine needles acidify soil until they degrade; this benefit lasts even after the compost has returned to a neutral pH.

Calculate how much dry garden fertilizer you need to sprinkle on the compost pile’s surface, and then apply it at around 1 cup (237 ml.) per square foot (929 cm.).

Completed compost can be used in place of garden soil if there is a shortage. Put to use a fertilizer created specifically for acid-loving plants.

Soil microorganisms will help speed up the breakdown if you cover the compost pile with an inch or two of garden soil (2.5-5 cm).

How To Use Ericaceous Compost?

Your compost can be used in several ways to help acid-loving plants. Compost can be sprinkled over flower gardens and tree beds and raked into the soil, or it can be mixed with potting soil and used to sow ericaceous plants in containers.

Before planting, new plants can be given a head start by amending the soil with ericaceous compost or another high-acid growth medium.

Compost rich in ericaceous materials should comprise the bulk of your planting medium. Soil acidity can be lowered as this material decomposes due to its acidic constituents.

You should regularly add items from the above list or more ericaceous compost. The most effective method is to use compost as mulch on top of your “lime-hating” plant beds.

Using ericaceous compost will aid in creating the optimal circumstances, with the proper pH levels, for growing acid-loving plants. In addition, compost will aid in keeping the soil at an ideal moisture and drainage level for your plants.

Do Blue Hydrangeas Need Ericaceious Compost?

Blue flowers on mophead & lace-cap hydrangeas can only be grown in acidic soil with a pH between 5 and 5.5. Flower colors change from white to pink when cultivated in acidic soil.

Growing blue hydrangeas necessitates a soil pH of 5.0 to 5.5. You can get the right soil pH by adding ericaceous compost to the hydrangeas above, allowing you to grow blue blossoms.

Still, keep in mind not all hydrangeas can change their blossom color. As an illustration, white hydrangeas will always produce white flowers.


Even if you don’t have a green thumb, you can still enjoy the aesthetic value of a container-grown eucalyptus plant in your garden or indoors.

If planted in a container with the proper, well-draining compost, they are among the few tree species that will thrive.

You can utilize any free-draining compost, like standard garden compost mixed with garden sand. However, due to its excellent drainage, ericaceous compost is one of the best solutions for eucalyptus trees.

We hope you must have acknowledged everything regarding whether can you use ericaceous compost for eucalyptus and how to utilize it in your garden.
