What We Stock

Mushroom Compost

Mushroom compost is an excellent soil conditioner that is both high-quality and affordable. It helps to strengthen the composition of heavy clay soil and sand-like soil, improves quality by adding humus and plant nutrients, and boosts soil structure. Mushroom compost is perfectly suited to vegetable gardens, flower beds or any other type of garden soil.

Screened Poultry Manure

Poultry manure is an excellent non-chemical fertiliser that contains a blend of nutrients such as nitrogen, phosphate and potash. Slightly alkaline in nature, poultry manure is the perfect fertiliser for vegetable and fruit crops. This is an environmentally friendly option that’s completely organic and packed with nutrients.

Premium Compost

Our Premium compost is an in-house combination of untreated, decomposed blended raw materials screened to 20mm minus that has been watered and turned over a period to reach its maximum potential to help boost enzymes in the bleakest of subsoils. It can be used in the basic composted form as a soil improver in a variety of different situations including home gardens, horticultural & agricultural applications, urban landscaping, and rehabilitation.


Which compost to choose?

The most popular type of compost can vary depending on factors like location and gardening preferences. However, mushroom compost is often a popular choice among gardeners. Mushroom compost is made from the leftover materials used to grow mushrooms, such as straw, manure, and other organic matter. It’s known for being rich in nutrients and beneficial microorganisms, making it excellent for improving soil fertility and promoting healthy plant growth. Additionally, mushroom compost typically has a neutral pH, making it suitable for a wide range of plants. Overall, mushroom compost is a versatile and widely appreciated option for enriching garden soil.

What should I use mushroom compost for?

You can use compost to improve your garden soil. It’s great for adding nutrients and improving soil structure, which helps plants grow better.

When should you not use mushroom compost?

Avoid using mushroom compost if you’re growing plants that prefer acidic soil, as this compost can sometimes raise the pH level. Additionally, if you’re concerned about potential contamination from mushroom growing chemicals or pesticides, it’s best to avoid using this type of compost.

Does mushroom compost attract worms?

Yes, mushroom compost can attract worms because it’s rich in organic matter and nutrients, which are food sources for worms. Worms play a major role in soil health by breaking down organic matter and improving soil structure. They help aerate the soil and distribute nutrients, which can benefit plant growth. So, having worms in compost is generally a good sign of healthy soil.

Can you use mushroom compost on Australian natives?

Yes, you can use mushroom compost on Australian native plants, but it’s important to use it cautiously. While this compost is beneficial for improving soil fertility and structure, some Australian native plants prefer low-nutrient soils. These plants are adapted to the specific conditions of Australian landscapes, which may include nutrient-poor soils. Therefore, it’s recommended to use this compost sparingly or in combination with other soil amendments to avoid over-fertilising native plants. Additionally, always research the specific needs of your native plants to make sure they thrive in their environment.

What is poultry manure and how is it different from mushroom compost?

Poultry manure is poop from chickens or other birds. It’s rich in nutrients like nitrogen, phosphorus, and potassium, making it a valuable organic fertiliser for plants. People use it to help plants grow better.

Mushroom compost is what’s left over after growing mushrooms. It’s made from things like straw, hay, and yes, poultry manure. But it’s not just raw poop—it’s gone through a special process to make it great for plants. It’s like turning leftovers into a yummy meal for your garden. So, while both can help plants, mushroom compost is a fancier version that’s been specially prepared for gardening.
