Mushroom compost is a nutrient-filled blend of straw, peat, gypsum and other organic products. It is a by-product of mushroom farming and can be used as a fertilizer and organic soil amendment for many plants. Mushroom compost can be used as a mulch or worked into your garden beds as a soil amendment. When mulching, you should spread a layer of 2 to 5 cm (1 to 3 inches) of mushroom compost. When using mushroom compost as a soil amendment, plan on working in a 3-inch layer if you have sandy soil or a 1- to 2-inch layer if you have clay soil.

What You'll Learn
Use a wheelbarrow to transport compost to the desired area
When preparing to transport mushroom compost, it's important to consider the amount of compost you'll be moving and the distance you'll need to travel. A wheelbarrow is an excellent tool for this task, allowing you to move a sizeable quantity of compost in one trip. Here are some detailed steps and considerations to keep in mind when using a wheelbarrow to transport mushroom compost to your desired area:
Firstly, ensure you have a suitable wheelbarrow that can handle the weight and volume of compost you intend to move. Shovel small loads of mushroom compost into the wheelbarrow, being careful not to overfill it. Overfilling can lead to strain and difficulty when pushing the wheelbarrow. Once you've loaded the compost, you can wheel it to your desired location. If you have a helper, they can spread the compost with a rake or a garden hoe while you continue transporting more loads. This can significantly improve the efficiency of the task.
When pushing the wheelbarrow, be mindful of your surroundings and choose a path that minimizes the risk of spills or accidents. You may encounter obstacles or uneven terrain, so proceed with caution. Additionally, remember to lift with your knees, not your back, when handling the compost to avoid any strain or injury. Take your time, and if you need to move a large amount of compost, consider making multiple trips with smaller loads.
If you are planning to have a large batch of mushroom compost delivered, it's essential to check with your city's ordinances first. There may be regulations regarding how long a pile of compost can remain on the street, and you'll want to avoid any potential issues. Overall, using a wheelbarrow to transport mushroom compost is a straightforward process, but it's important to prioritize safety and efficiency to make the task as smooth as possible.

Spread compost with a rake to the desired thickness
Once you've shovelled your mushroom compost into a wheelbarrow and transported it to your desired location, it's time to spread it with a rake. This is a straightforward process but requires some precision to ensure you achieve the desired thickness.
First, decide on the thickness you want for your compost layer. This decision will depend on the purpose of your compost. If you're using mushroom compost as a mulch, a layer of 1 to 3 inches (or 5cm) is generally recommended for effective weed suppression and water retention. If you're using it as a soil amendment, the thickness will depend on the type of soil you have. For sandy soil, a 3-inch layer is suggested, while for clay soil, a thickness of 1 to 2 inches is more appropriate.
Now, grab your rake and start spreading the compost evenly across the designated area. Work carefully, ensuring that the compost layer achieves your desired thickness. If you're mulching, you can simply spread the compost without needing to work it into the soil. On the other hand, if you're using the compost as a soil amendment, you'll need to use a garden hoe to work it into the soil after spreading it with the rake.
Remember to take precautions to avoid strain during the process. Don't overload your wheelbarrow, and always lift with your knees, not your back. By following these steps and paying attention to detail, you'll effectively spread your mushroom compost to the desired thickness, setting the stage for a healthy and vibrant garden.

Use mushroom compost as a mulch to suppress weed growth
Mushroom compost is a nutrient-filled blend of straw, peat, gypsum, and other organic products. It is a by-product of mushroom farming and can be used as a mulch or soil amendment. When used as a mulch, mushroom compost helps suppress weed growth, retain water in the soil, and keep soil temperatures stable.
To use mushroom compost as a mulch to suppress weed growth, follow these steps:
Firstly, measure the length and width of the area you want to cover with mulch. For areas with irregular borders, measure at their widest and longest points. This will help you determine the amount of mushroom compost you need.
Next, shovel small loads of mushroom compost into a wheelbarrow. Wheel it to the area you want to mulch and dump the compost there. You can choose to wheel and dump all the compost before spreading or dump and spread each load as you go. If you have a helper, one person can spread while the other delivers the loads of compost.
Now, spread the mushroom compost across the desired area with a rake. Apply a layer between 1 and 3 inches thick, with 3 inches being the optimal depth for weed suppression and water retention. If you are mulching around young trees or shrubs, a 5cm (2-inch) layer is recommended. Avoid using mushroom compost as mulch for "acid-loving" or "ericaceous" plants, such as rhododendrons, camellias, azaleas, and heathers, as they struggle to access nutrients in higher-pH soils.
By following these steps, you can effectively use mushroom compost as a mulch to suppress weed growth and improve the health of your garden.

Work compost into the soil with a garden hoe for soil amendment
Mushroom compost is a nutrient-filled blend of straw, peat, gypsum, and other organic products. It is a healthy addition to the soil, with a pH that is ideal for most plants. It improves soil texture and drainage and adds nutrients to the soil.
When using mushroom compost as a soil amendment, use a garden hoe to work the compost into the soil. The amount of compost you should use depends on the type of soil you have. For sandy soil, use a 3-inch layer, and for clay soil, use a 1- to 2-inch layer. If you are amending the soil in containers, use a ratio of 1 part mushroom compost to 3 parts garden soil.
To work the compost into the soil, start by shovelling small loads of mushroom compost into a wheelbarrow. Wheel it to the area where you want to amend the soil and dump the compost there. Then, use a garden hoe to mix the compost into the soil. Make sure to lift with your knees, not your back, to avoid strain.
If you have a helper, one person can spread the compost with a rake to the desired thickness while the other delivers the loads of compost. Work the compost into the top 6 inches of soil. When using mushroom compost, be aware that it has high salt levels, which can harm germinating seeds and young seedlings.

Avoid using mushroom compost for acid-loving plants
Mushroom compost is a healthy soil addition that has a pH that is ideal for most plants. It can be used as a mulch or worked into your garden beds as a soil amendment. When mulching, you should use between 1 and 3 inches of mushroom compost. Mushroom compost is generally used annually as a soil treatment or a mulch rather than as frequent food for plants.
However, it is important to note that mushroom compost is slightly alkaline, with a pH of 6.5–7, and should not be used for acid-loving or 'ericaceous' plants. The chalk in mushroom compost increases the pH of the soil, making it more alkaline, which is less suitable for these plants. Acid-loving plants include rhododendron, camellia, heather, azaleas, and citrus plants, which thrive in acidic growing conditions.
If you are unsure about a specific plant, it is recommended to research that plant or conduct a small trial by using mushroom compost on one plant and comparing its growth to another plant of the same type without the compost.
Additionally, while mushroom compost is excellent for vegetable gardens, it is not suitable for fruit crops, which generally prefer neutral to acidic conditions. It is also not recommended for use as a lawn top-dressing unless the soil is very acidic and in definite need of lime.
