Traditional mulch, like wood chip mulch, is important in the garden, as it creates a vital layer that protects fragile plants and flower beds by allowing soil temperatures to remain constant, retain moisture, and suppress weed growth.

Mulch alternatives are an economical option to buying expensive mulch varieties while still retaining the benefits that it brings.

Mulch Alternatives

There are two main types of mulch: organic mulch and inorganic mulch.

  • Organic mulch materials are varieties like wood chips and bark mulch. These are anything that breaks down and returns to the soil.
  • Inorganic mulch alternatives use items that do not break down and return to the soil.

There are great mulch alternatives that come in both organic and inorganic varieties.


Organic Mulch Alternatives

Organic material for mulch is attractive because while it breaks down, it returns nutrients to the soil. Therefore, organic mulch alternatives bring all the benefits of mulch like retaining soil moisture and preventing weeds while bringing nutrients to the soil as well.


Grass Clippings

Grass clippings are an item that almost everyone has as a by-product of cutting the lawn. However, this kind of mulch alternative needs some preparation before it is ready to spread over your plants and flower beds. To be effective, you must keep the grass clipping layers loose and thin and allow them to dry out before layering more clippings on top.

Pros

  • This is an inexpensive but effective way to mulch.
  • Grass clippings add nutrients like nitrogen to the soil which is great for tomatoes, lettuce, and kale.

Cons

  • You cannot use grass that has been treated for weeds as this will damage your plants.
  • If you pile grass cuttings around your plant roots, it can heat up and destroy the plants.

Pine Needles

Pine needles, the leaves of pine trees, are another organic mulch material that is an effective and sustainable alternative to mulch. If you have a supply of pine needles from trees on your property, this is a good choice for you.

Pine needles, also called pine straw, do not pack down but create a permeable layer for water and other nutrients. Fresh pine needles contribute to acidic soil, so these are not good for every flower bed.

However, pine mulch is good for hydrangeas, camellias, azaleas, nasturtiums, and daffodils among others.

Pros

  • This is an alternative mulch that looks natural and beautiful.
  • This mulch alternative helps the soil retain moisture and essential nutrients.

Cons

  • Pine straw breaks down over time, so it will cost time and money to replace.
  • Contributes to a lower pH of the soil.

Straw Mulch

Straw mulch is an excellent mulch alternative according to many garden experts. It is great at retaining soil moisture, a good weed barrier, and prevents the soil from compacting too much. Straw mulch, unlike hay mulch, does not contain seeds.

Also, straw mulch reduces potentially harmful insects and plant diseases like rot.

In addition, straw will decompose over time and will release nutrients to the soil that will help your plants to thrive.

Pros

  • This is an inexpensive form of alternative mulch because it does not cost much to buy and it does not break down like other organic mulch alternatives and need to be replaced as much.
  • This is an effective mulch alternative that many experts recommend.

Cons

  • Some people find this mulch alternative unattractive as the golden color and texture stand out from the garden soil.
  • Even though seeds should not be present in straw, there are sometimes seeds in the straw that will take root in your garden beds.

Compost

One nutrient-rich mulch alternative is using composted materials. Compost is an alternative to mulch that you create over time.

This organic mixture is composed of discarded organic material like vegetable peelings, grass clippings, tea bags, leaves, cardboard egg cartons, and plant prunings. Compost must be the right balance of materials and needs to be mixed and turned so that all the material has been aired before you cover your plants.

When compost is used as garden mulch, it brings a flood of nutrients to the soil and is wonderful for retaining moisture. Some gardeners recommend adding animal compost to other organic compost to provide even more nutrients to the soil.

However, make sure that all the compost, including the animal compost, has been dried before use so that it does not burn your plants.

Pros

  • Compost adds light texture to a soil that is good for healthy plant growth.
  • Unlike other organic mulch material like wood mulch, there is no nitrogen depletion from the soil with compost.

Cons

  • Compost is expensive if you don’t make it yourself.
  • Compost can have a bad odor.

Cocoa Bean Hulls

Cocoa bean hulls are the outer layer of a cocoa bean that comes off when the bean is roasted. They are free from weeds and are sterilized in the roasting process. Many gardeners love the dark look of this mulch and the sweet smell that they produce. This is one of the best alternatives to mulch if you are looking for an option that is good for the environment because you are using a product that would otherwise be discarded.

Pros

  • This is a good option for keeping the soil moist and providing nutrients to the soil like nitrogen.
  • This mulch alternative has a dark color and smell that many find attractive.

Cons

  • This is not one of the best mulch alternatives for dogs or other animals as these hulls can be toxic.

Leaves

Almost everyone has ready access to leaves making them the perfect mulch alternative. However, to take advantage of leaves for mulch, you should prepare them by sending them through a shredder. Otherwise, leaves form a layer that is too thick and creates an unsuitable living environment for small plants. Leaves are a good way to maintain consistent soil temperatures, suppress weeds, and bring more nutrients to the soil.

Pros

  • Shredded leaves are one of the most inexpensive mulch alternatives.
  • This is a good mulch alternative for soil aeration.

Cons

  • Like all organic mulches, compost brings nutrients to the soil. However, as leaves break down they leach nutrients away from the soil and cause some stunted growth.
  • It takes time to shred and dry the leaves for use as mulch.

Inorganic Mulch Alternatives

If you decide to go with an inorganic alternative to mulch, it will not give nutrients to the soil as it breaks down. However, unlike organic mulch, some inorganic alternatives will not break down at all. Therefore, these will last longer and preserve the quality of the soil underneath.


Rock Mulch

Rock or stone mulch, like pea gravel or river rock, is an attractive and long lasting alternative to traditional mulch. Like other mulch alternatives, rocks help the soil underneath retain moisture and keep weed growth at bay.

Also, pebble mulch alternatives do not wash away or deteriorate over time. In addition, there is so much variety in rock mulch types that you can find one to fit any garden landscape and home style.

However, unlike other organic forms of mulch, it does not contribute back to the soil with nutrients or soil regeneration.

Pros

  • This is an attractive mulch alternative with a wide variety of types.
  • Rocks keep unwanted plant growth at bay and are good for retaining moisture in the soil.
  • Rock mulch is good in cooler climates as the rock retains heat and extends the growing season.

Cons

  • Rock mulch is a more expensive option than other mulch alternatives.
  • Stone mulch does not contribute to the soil’s nutrient level or quality.

Landscape Fabric

Landscape fabric is a layer of breathable woven fibers that you lay over your beds to prevent weed growth and retain moisture. You must stake this fabric down throughout the bed which will prevent weeds from growing and make sure the fabric does not blow away.

While this is a helpful addition to your landscaping arsenal, landscape fabric needs to be coupled with other mulches because it is not an attractive top layer.

Pros

  • Landscape fabric retains moisture in the soil and is effective for preventing weed growth.
  • This kind of mulch alternative is inexpensive.

Cons

  • Landscape fabric is not attractive; you should couple this with another mulch alternative on top of the fabric.
  • Landscape fabric is fragile and needs to be replaced every season or every other season.

Rubber Mulch

Rubber mulch has become a popular mulch alternative because it is using recycled tires and it lasts for a long time. This mulch has an attractive dark color and is good at regulating soil in hot and cold temperatures. However, this is not a controversy free mulch as many say that there is a risk that it is flammable and that it has too many chemicals that are not safe.

Pros

  • This mulch is excellent for retaining water and reducing weeds in your beds.
  • Rubber mulch does not attract insects and pests like wood chips and other organic mulch material.

Cons

  • Rubber mulch is expensive.
  • This kind of mulch cannot be worked into the ground if you are refashioning the bed, so it must be removed by hand.
