Adding mulch to your garden beds is an essential step in maintaining healthy plants and productive soil. Mulch not only helps retain moisture and keeps weeds at bay, but it also protects plant roots from temperature fluctuations. However, purchasing mulch can get pricey, especially if you have large garden beds to cover.
Mulching involves adding a protective layer over the soil, which is especially beneficial for garden beds. This layer regulates soil temperature, minimizes weed growth, and locks in moisture, contributing to stronger plants and better yields. While there are many mulch materials to choose from, not all are budget-friendly or suitable for every garden type.
To help you mulch effectively and affordably, here are ten budget-friendly mulch options that will keep your garden beds thriving.
Here are the ten best mulch options for your garden beds.
Compost
Compost is an excellent mulch choice for garden beds, especially vegetable gardens, as it enriches the soil with vital nutrients while providing a protective layer. It improves soil structure and promotes healthy plant growth by slowly releasing nutrients over time.
Shredded Leaves
Using shredded or dried leaves as mulch is a great way to add nutrients to your garden beds. These leaves slowly decompose, enriching the soil without needing synthetic fertilizers. They’re perfect for naturally feeding your plants and improving soil structure over time.

Fresh Grass Clippings
Chemical-free, fresh-cut grass is a nitrogen-rich mulch, especially beneficial for leafy greens in your garden beds. Grass clippings help suppress weeds and retain moisture, but be sure to spread them in a thin layer to prevent waterlogging issues.

Bark or Wood Chips
Bark or wood mulch is a durable option that works well in garden beds. It effectively suppresses weeds, helps retain moisture, and gradually improves soil structure as it breaks down over time.
Stones and Gravels
For a longer-lasting mulch option, stones and gravel are excellent for weed suppression in garden pathways or decorative areas around your beds. Although they can be pricier, they are ideal for areas where you want a permanent mulch solution.
Garden Fabric or Burlap
Garden fabrics, burlap, or even large coffee bean bags can act as effective weed barriers in garden beds. This option is particularly useful around perennial plants, shrubs, and trees you won’t regularly replant. Landscape fabric also helps retain moisture while keeping weeds at bay.
Sawdust
Untreated sawdust can be used as mulch along pathways or around established plants. However, avoid using thick layers close to plant stems, as sawdust tends to compact and could prevent water and nutrients from reaching roots.
Newspaper
Layering newspapers under other mulch materials can help suppress weeds while gradually decomposing to enhance soil structure. It’s an affordable, easy-to-source option that works well when covered with leaves, straw, or compost.
Pine Needles
Pine needles, or pine straw, work well as a mulch, especially for acid-loving plants. They decompose slowly, adding a slight acidity to the soil, which benefits plants like blueberries and tomatoes.
Cardboard Boxes
Cardboard is widely available, easy to apply, and an eco-friendly mulch option. Layering cardboard under other mulch materials can suppress weeds and improve soil structure as it breaks down.
