What Is Compost, and What Does It Do for Plants?

Can You Fill a Raised Bed with Just Compost?
The short answer is no; you can’t fill a raised bed with just compost.
Compost can provide plants with the nutrients they need to grow, and it can also help to improve the structure and drainage of garden soil.
However, too much compost can hurt plants, so it’s crucial to use compost in moderation.
A layer of compost on top of your soil can help to replenish nutrients that previous plantings have depleted. It can also help to improve drainage and aeration.
But using too much compost can compact the soil and make it difficult for roots to penetrate. It can also create an environment too rich for delicate plants, leading to leggy growth or yellowing leaves.

How Much Compost to Use in Your Garden
If you’re looking to improve your garden soil, you might be wondering if you can just use compost as a soil amendment.
After all, compost can provide plants with the nutrients they need to grow and help improve the structure and drainage of garden soil.
Generally, you should use about 1 part compost to 3 parts garden soil. So, if you have a raised bed of 4 square feet, you need about one cubic foot of compost. To put that into perspective, one cubic foot of compost is about the size of a large garbage can.
When adding compost to a raised bed, aim for a layer 3-4 inches deep. This will give your plants the benefits of compost without harming them.
It’s also important to note that too much compost can actually hurt plants. Compost is high in nitrogen, which can burn plants if it’s not used in moderation. Be sure to mix compost with other materials, like garden soil, before using it in your garden.
