Are you trying to maintain a vegetable garden? Laying down a mulch blanket can help you out! Mulches help suppress the growth of weed, retain water and control water runoff. They can also help with temperature fluctuation. Read on as we discuss the best mulches for vegetable gardens.

What Are Mulches?

Mulch is essentially a layer of material that is laid out on the surface of the soil. It helps with maintaining a healthy garden and is considered a necessity of sorts. Some of the most commonly used organic mulches include:

  • Shredded or chipped bark
  • Straw
  • Pine Needles
  • Shredded leaves
  • Sawdust
  • Grass clippings
  • Newspaper (inorganic)

Most of these mulches are suitable for vegetable gardens. Others, like bark, are more suitable around shrubs and trees. You can also add them to garden beds that do not require a lot of digging.

Why Should You Add a Layer of Mulch?

As we have mentioned earlier, mulches are very important for your garden. Here is a quick review of some of the biggest benefits of adding a layer of mulch:

  • It helps retain the soil’s moisture.
  • Mulch can prevent the growth of weeds.
  • It helps regulate the soil’s temperature and keeps it cool.
  • Mulch can improve the structure, nutrient-holding capacity, and drainage capabilities of the soil when it breaks down.
  • It adds to the aesthetic appeal of your vegetable garden.


Which Are The Best Mulches For Vegetable Gardens?

Selecting the right type of mulch to add to your vegetable garden is very important. If you are new to gardening, here is a list of some of the best mulches for vegetable gardens.

1. Hay or Straw

If there is an outgrowth of weeds in your garden, then adding a layer of seedless hay can help. This organic mulch is excellent for weed control and is one of the best mulches for vegetable gardens available. It can also protect your plants from soil-borne diseases. It decomposes quickly, so make sure you replenish the layer regularly to control the growth of weeds.

If you are using this mulch for your vegetable garden, make sure to use good-quality hay that does not carry brambles and weed seeds. You can try getting fresh legume hay instead. This is a good source of nitrogen for the soil and can enrich it with essential nutrients.

2. Leaves

You can create a layer of dry leaves in your vegetable bed. Leaves are generally easy to obtain, and you shouldn’t have trouble sourcing them for your garden. There are multiple options you can explore here too. You can add a blanket of leaves on top of the soil or you can turn the leaves under the soil.

The second option applies to empty garden beds. You can let the leaves decompose in the soil during the winter. Once spring arrives, the soil will be perfect for planting new vegetables.

3. Sawdust

Sawdust is rich in carbon but low on nitrogen. If you have just planted seeds in your vegetable garden, then adding a thin layer of sawdust can help encourage growth. Sawdust is also good at limiting the growth of weeds and helps in moisture retention, which ensures your root systems stay hydrated.

If you are expecting rain, then we suggest you avoid using this mulch for your vegetable garden. Sawdust has the tendency to crust over and form a layer over the soil. This can make it difficult for the rainwater to absorb into the soil.

4. Grass Clippings

Grass clippings are among the best mulches for vegetable gardens. They provide good weed control and are much easier to acquire than seedless hay or sawdust. If you are using grass clippings as mulch, make sure to start with a thin layer and build it gradually.

Avoid using fresh grass when making a layer of grass clippings. This can emit a lot of heat and may cause other organic materials to decay. If the grass layers are too thick, then they will also mat and not receive sufficient oxygen. This can cause the grass to produce a foul odour.

To avoid these problems, we recommend using dry grass. If used in limited quantities, dry grass clippings can also decompose quickly and add nutrients to the soil. You should also steer clear of crabgrass and grass clippings from a lawn that has been subjected to herbicide or fertilizer treatment.

5. Newspaper

As far as inorganic mulches go, a newspaper is one of the best mulches for vegetable gardens. It is incredibly easy to source and is 100% biodegradable, so you don’t have to worry too much about the environmental impact. It also offers reasonably good weed control.

You can consider putting down five layers of newspaper. Since this type of mulch degrades fairly quickly, a thicker layer can help the mulch last longer. If you are worried about the newspaper blowing away, here are a few things you can do:

  • Spray some water over the newspaper to make it damp
  • Add a little soil onto the edges of the newspaper
  • Cover the newspaper with a layer of organic mulch like seedless hay or sawdust

Additional Tips for Adding Mulch To Your Vegetable Garden

If you are adding a layer of mulch to your garden, we suggest keeping the following tips in mind for best results:

  • Make sure the layer of mulch is at least 2 to 3 inches deep. If the layer is too thin, then weeds will still grow through. If it is too thick, then the mulch may interfere with adequate water absorption.
  • Keep replenishing the layers if you are using organic mulch. These materials decay much faster and you may need to reapply a layer more than twice a year.
  • Avoid adding a layer of mulch around the stems or the trunk of plants. This can cause the stems to decay. It can also interfere with the growth of the plant.

Wrapping It Up

Adding a layer of mulch to your vegetable can help with weed control, control pests, and improve the structure of the soil by adding more nutrients. Some of the best mulches for vegetable gardens include seedless hay, straw, grass clippings, newspaper, sawdust, and leaves.
