If you are looking for the perfect organic matter to improve the soil around your Japanese maple, look no further than compost! Compost is a rich and beneficial material that can provide your tree with everything it needs to grow healthy and strong. In this article, we will discuss the basics of composting for Japanese maples, as well as some of the best products on the market today. We’ll also provide some tips on how to use compost to get the most benefit from your tree.

What is compost and why do I need it for my acers

Compost is a soil amendment made of decomposed organic matter. It is used to improve the structure and fertility of soils. Compost can be used to provide nutrients to plants, help retain water, and suppress plant diseases.

Acer palmatum, or Japanese maple, is a delicate tree that requires well-drained soil with a pH range of neutral to slightly acidic. The addition of compost can help adjust the pH level of your soil and improve drainage.

There are many different types of compost available on the market. When choosing a compost product for your acers it is important to consider the ingredients, particle size, and price.


The best fertiliser products for acers will contain a mixture of manure, peat moss, leaves, and bark. Manure adds important nutrients like nitrogen and phosphorus that are needed for leaf growth. Peat moss helps improve drainage and aeration in the soil. Leaves and bark add organic matter which helps improve the structure of the soil.

Particle Size

It is important to choose a compost with small particles so it can easily be incorporated into the soil around your acers. Large particles can compact the soil and reduce air circulation which can lead to root rot.


Compost prices can vary depending on the type and brand of product you purchase.

How to make compost for your acers

If you are unable to find a compost product that meets your needs, you can also make your own compost at home. The process of making compost is simple and can be done with materials that are commonly found in most households.

To make compost, start by collecting organic matter like leaves, grass clippings, food waste, and plant trimmings. You can also add manure or coffee grounds to the mix. Next, mix the organic matter together in a pile and keep it moist but not wet. Allow the pile to sit for several months until it has decomposed into a dark brown soil-like material.

You can use this homemade compost as a topdressing around your Japanese maples or incorporate it into the soil before planting.

Making your own compost is a great way to recycle household waste and improve the health of your acers at the same time.

The benefits of using compost for your acers

There are many benefits to using compost for your acers. Compost can improve the structure of the soil, help retain water, and suppress plant diseases. In addition, compost provides essential nutrients like nitrogen, phosphorus, potassium, and magnesium that are needed for healthy growth.

Adding compost to your Acer’s planting hole is a great way to give them a head start on life. The extra nutrients in the compost will help them to grow faster and be more resistant to disease.

If you have an existing Japanese maple that is not doing well, adding compost to the soil around it can also help revive it. The added nutrients and improved drainage will help it to recover from any stressors it may experiencing.

Acer pests and diseases that can be treated with compost

There are several pests and diseases that can affect Japanese maples. Some common ones include aphids, scale insects, spider mites, root rot, and bacterial leaf spot.

Compost can be used to treat many of these problems:

  • Aphids: Aphids can be treated with a mixture of compost and water sprayed directly on the affected plants. The compost will help to kill the aphids and also provide nutrients to help the plant recover.
  • Scale Insects: Scale insects can be removed from plants with a mixture of compost and rubbing alcohol. The alcohol will dissolve the wax covering their bodies while the compost will kill them.
  • Spider Mites: Spider mites can be killed with a mixture of compost and water. The compost will smother the mites while the water will help to wash them away.
  • Root Rot: Root rot can be treated by adding compost to the soil around the affected plant. The compost will help improve drainage and aeration in the soil, which will help to combat the root rot fungus.
  • Bacterial Leaf Spot: Bacterial leaf spot can be treated with a mixture of compost and water sprayed directly on the leaves of infected plants. The compost will help kill the bacteria while also providing nutrients to help the plant recover.

Compost is an essential tool for keeping your Japanese maples healthy and looking their best.
