The general rule of thumb is 1/4 to 1/2 inch if applying to the top of the soil and 1 to 2 inches amended to 6 to 8 inches when amending into the soil. Recommended maximums are 25% to 30% compost in a soil blend, but no more than 25% compost in containers.

Can you have too much compost in your garden?
Adding compost to your soil can increase soil organic matter and improve soil health and fertility, but too much compost can cause problems for the health of your plants.
The amount of compost you should add depends on several factors, including the type of soil you are growing in, the size of the plants you want to grow, and how much you plan to use in your garden. For example, if you have a small garden, you may not need to add any compost at all.
If you’re growing a large garden with a lot of plants, however, it may be a good idea to consider adding a little compost.
How much compost do I need for a small garden?
A single bag of compost will cover an area of 2.5 feet long x 2.5 feet wide and 2 feet deep for new vegetable and landscape beds. The bag should be placed in the compost pile at the beginning of the growing season.
The compost should not be allowed to dry out, as this will reduce the amount of organic matter that can be incorporated into the soil. When the bag is full, remove it from the pile and place it in a plastic bag to keep it fresh.
Can I just put compost on top of soil?
You can sprinkle compost on top or mix it into your flower and vegetable beds, gently rake compost into tree beds, blend it with potting soil to revitalize indoor plants, or spread it on top of your garden beds. The amount of compost you need depends on the size of the garden and the type of soil you’re growing in.
For example, if you have a 10-acre garden, you’ll need about 1.5 to 2 pounds of organic matter per 1,000 square feet of garden space. If you live in a smaller space, like a one- or two-bedroom apartment, your compost needs will be lower.
Do I need to mix compost with soil?
Compost increases the soil’s ability to shed or retain water, as well as adding a low level of nutrients, in vegetable gardens. Potted plants, flower gardens, and new trees and shrubs can also benefit from composting.
Can you fill a raised bed with just compost?
No, you should never fill a raised bed with only compost. When creating a soil blend for your raised beds, it’s important to account for at least 30% of your garden soil. Compost will give your plants a lot of nutrition, but the soil will drain away too quickly and cause the plants to die.
If you don’t have access to a compost pile, then you can make your own soil mix by mixing 1/2 cup of peat moss with 1 gallon of water. Mix the mixture well and let it sit for a few days before adding it to your soil. You can also add a small amount of vermiculite to the mix if you want to add some extra nutrients.
Do compost bins work?
A compost bin works by creating the ideal environment for decomposition. Compost bins are designed to contain everything in a sanitary and clean manner. Composting is a great way to reduce the amount of waste in your home and reduce your carbon footprint. It is also an environmentally friendly option for those who do not have access to a composting facility.
Is compost better than fertilizer?
Compost is better thought of as a “soil amendment” than a fertilizer. Compost improves plant health and growth and adds other benefits, so we use this term. It is possible to improve soil structure and achieve better drainage, aeration, and water retention.
In addition, compost can be used to improve the soil’s ability to hold water. below)

- Water retention soil is made up of organic matter
- Many other elements
When compost is added to soil, these elements are broken down into smaller, more easily digestible forms. This process is called decomposition.
The breakdown of the organic material in soil is a natural process, but it can also be slowed down by adding compost to the mix.
Why is my compost killing my plants?
The slow release of compost helps grow plants. Compost that is not matured correctly can be harmful to your plants. The beneficial microbes in your compost can be killed by using too much compost.
