Planting cover crops is an essential part of maintaining soil health, improving crop yield, and promoting sustainable gardening practices. But when it comes to choosing the best material for planting cover, many gardeners are faced with a decision: tree peel or hay? In this blog, we’ll explore the benefits of both and discuss which one might be better for your garden, using various terms related to sustainable gardening and cover crops.
Tree peel as a planting cover
Tree peel, often used as mulch, is an organic material that offers numerous benefits to home vegetable gardens. When placed on top of the soil, it acts as a living mulch, helping to regulate soil temperature, retain moisture, and prevent weed growth. One key advantage of using tree peel is its ability to improve soil health over time. It slowly decomposes, contributing to soil organic matter and enhancing the soil’s overall structure.
Tree peel also plays a role in nitrogen fixation, especially when paired with legumes like crimson clover. As the peel breaks down, it releases nutrients that are beneficial for plants and soil microorganisms.
Additionally, tree peel can assist in breaking up compacted soil, allowing for better root penetration and carbon dioxide movement through the soil layers.

For gardeners practicing no-till gardening, tree peel is an excellent option. It prevents soil erosion by acting as a barrier, minimizing the impact of rainfall and reducing nutrient leaching. This can be particularly beneficial in areas with tile drainage, as it helps retain nutrients while allowing excess water to flow away.
However, tree peeling has its limitations. It may not provide as much biomass yield as other cover crop options, and its ability to promote plant diversity is somewhat limited compared to planting cover crops like Dutch white clover or buckwheat.
Hay as a planting cover
Hay, on the other hand, is a versatile cover material that offers excellent benefits for soil health and water retention. It is a great choice for succession planting and can be used as mulch in both row planting and garden paths. Hay’s organic matter enriches the soil, improving soil nutrient cycling and promoting the growth of beneficial soil microorganisms.
One of the significant advantages of hay is its role in erosion control. Its soft, thick layer helps prevent soil crusting, ensuring that the soil remains loose and able to absorb water. This is crucial for rainfall infiltration, reducing the risk of soil erosion and nutrient leaching.
Hay also promotes plant diversity when used in a multi-species mix with other cover crops like oats, peas, and radishes. The allelopathy effect of some hay varieties, such as cereal rye, helps suppress weeds while benefiting crops through companion planting. In addition, hay can support pollinators like bees, creating a healthier ecosystem for both plants and animals.
However, hay can sometimes harbor weed seeds, which might lead to unwanted plant growth in your garden. For no-till farming, hay might not always be the best choice, especially if you’re aiming to reduce the need for weed control.
Which is better?
The answer depends on your garden’s specific needs. If you’re looking to improve soil health, retain moisture, and promote long-term sustainable gardening, tree peel may be the better option. It works well in no-till systems, contributes to soil organic matter, and supports nitrogen fixation.
On the other hand, if you need a versatile material that offers better erosion control, improves water retention, and encourages plant diversity, hay might be the way to go. Its ability to support companion planting, prevent soil compaction, and enhance crop yield makes it a strong contender.
In some cases, combining both materials might give you the best of both worlds, providing your garden with optimal soil health and plant diversity while reducing soil erosion and retaining essential nutrients.
By understanding the benefits of tree peel and hay, and how they relate to concepts like cover crop species, ecosystem variability, and soil biology understanding, you can make an informed choice that best suits your gardening goals.
