Using Straw as Mulch

Using straw as mulch is a great idea because it is a type of organic matter that can really help your garden in so many ways. Straw as garden mulch has so many great uses. It can help prevent weeds, enrich your soil, and so much more!

Let’s start by looking at the many different uses of straw. 

Where Does Straw Come From?

Straw is considered to be a type of by-product of the main crop. It is the stalk of grain crops such as wheat, barley, or rye.

After the seed heads containing the grain are harvested, the hollow stems of the grain are formed into bales, that are either round or rectangle-shaped and stored in dry locations for later use.

Uses of Straw

Animal Bedding

One of the most common uses of straw is to be used as animal bedding on a farm. No matter if we are talking chickens, cows, or horses, most farm animals enjoy using straw as their primary bedding. 

As Protective Layer

Another use of straw is as a protective layer. A thin layer of straw makes a great protective layer on a new lawn so that the grass seeds stay in place and are allowed to grow without being disturbed. 

Compost Pile

Another great use of straw is in your compost pile. It typically decomposes quickly and attracts worms. 

As Mulch

Another great use for straw is as mulch in your veggie gardens or even flower gardens. This is where we are going to focus our attention specifically on this topic.

Benefits of Mulch

Weed Suppression

One of the great benefits of using straw as mulch is that it helps prevent weed growth in your garden during the growing season. This is one of my personal favorite reasons for using straw. 

When you spread straw in a thick layer around the base of your young plants, the thick layer will prevent weed germination and the invasive plants from growing altogether. 

This is a fantastic way to stay on top of weeding your garden this season. Plus, the mulch layer will prevent any additional weed seeds from growing. Keep in mind, this works best when spreading a thick layer of straw around your plants after the garden has been freshly weeded. 

You will also want to be careful to not spread too much straw too close to the plants so that they don’t get choked out. 

Prevents Compaction

You might notice that your dirt contains a lot of heavy clay soil. If this is the case, you may consider tilling into the soil a few inches of mulch to help break the soil up and prevent it from being quite so compacted. 

An added benefit when you are trying to fix soil compaction is to mix in a little sand in addition to your straw mulch to get added drainage and end up with nice soil for growing your plants. 

Soil Moisture

Depending on your weather conditions, especially if you need to retain extra moisture, using straw as mulch is a great way to achieve water retention.

No matter if you are trying to conserve water due to rainfall shortages or simply not wanting to water as often, straw helps to trap the water, and keeps the dirt wet much longer as compared to spaces without straw. 

A word of caution though, when it comes to using straw as mulch to retain moisture, you will want to be careful that you do not get the soil too wet, as you could run the chance of fungal diseases in leaf mold due to wet straw.

Soil Temperature

You can also use a straw to regulate soil temperatures. Plus, you can use a straw to help keep soil cool underneath the straw during hot weather. 

Prevents Erosion

Straw can also be used to help prevent erosion, or as a protective layer. This especially comes into play when you are dealing with a large garden space or planting a new layer of grass.

You want to prevent the dirt from eroding away, so adding a thin layer of straw will help your soil stay in place and thrive. 

Organic Material

Straw is also an organic mulch, and as it decomposes it can be used as a nitrogen fertilizer. This is great for your garden or your own compost pile. Straw is also an excellent soil amendment and helps to add nutrients as it decomposes.

How to Use Straw Mulch

Vegetable Garden

Likely, the most common and most beneficial way to use straw as mulch is in a vegetable garden. Vegetable plants can often be overrun very easily by weeds, and it’s hard to stay on top of them.

If you simply add a layer of straw around the young garden plants in early spring, you can help prevent the weeds from getting started in your garden. 

You want to be careful that you don’t add too much straw mulch around the plants, as you may choke out the plants as well as the weeds. Ideally, you will want to leave a little space around plant roots for them to get air and rain, then you can add a thick layer of straw in between the plants so that the weeds can’t grow across the soil surface. Using straw around potato plants is another great way to protect the plants as they grow. 

The amount of straw you need to use as mulch will depend upon your specific garden area. A small garden will take far less amount of straw than large gardens will. 

Not only do straw blades help protect your vegetable garden from unwanted weeds taking over, but it also helps to enrich the garden soil and keep it a happy and healthy soil for your plants to grow in.

To use straw as mulch in your vegetable garden, you’ll want to wait until early spring, after your vegetable plants have started growing, and you can see them a few inches above the ground. 

Once they are young plants, you will want to weed the garden well, then sprinkle straw around each plant, leaving some space for the plant to get air and water so that it doesn’t suffocate. 

Then, layer the straw in a thick layer between the vegetable plants. You may need to check on the vegetable garden another time or two, to make sure no weeds have managed to sneak in. 

Throughout the growing season, you may need to add additional straw another time or two, to keep it thick between the plants.

Garden Beds

Not only can you use straw as mulch in your vegetable garden, but you can also use straw as mulch in raised garden beds, or in ornamental beds where you tend to grow perennials or annual flowers.

To use straw as mulch in your garden beds or flowerbeds, you will want to wait till early spring when your plants start to grow.

After your plants grow, give the flower bed or vegetable garden a good weeding, then sprinkle some straw around the base of each plant. 

This will help the plants to able to grow but will also help prevent additional weeds from growing.

Winter Protection

Another use for straw is as winter protection around some of your more delicate plants. Spreading it around plants like blueberry bushes will help them to survive the harsh winter weather.

Other Types of Mulch

In addition to using straw as mulch, there are other natural types of mulch materials you could use as a substitute for straw. Here are a few other types of mulch:

Hay Mulch

Although sometimes confused with straw, hay is animal feed. The primary use for hay is to feed animals, although it can be used similarly to straw, to help prevent weeds and trap moisture in the soil.

Pine Needles

Pine needles are another type of mulch. As you may have guessed, these come from pine trees. Typically, when we think of pine mulch, we think of long-needle pine which is often used as mulch, in flowerbeds, gardens, and compost piles.

Another name for pine mulch is pine straw. This refers to dead pine needles, which can be used as mulch in flowerbeds and gardens.

Grass Clippings

Yet another type of mulch material is grass clippings. Grass clippings can be used in a similar manner as other types of mulch. Plus, these mulch materials help prevent weed growth, and enrich the soil at the same time.

Wood Chips

Wood chips are another type of mulch, these are a more common type of mulch, which is typically used in flower beds or in other ornamental beds to help prevent weed growth, and make it look nice.


Where to Find Straw

What if you would like to use straw as mulch, and are trying to figure out where to find it? Where you can pick it up primarily depends on what area of the country you are in.

If you are in city locations, you might have to try and find it at your garden center. However, if you are near farmland or the countryside, your best bet is going to be to contact a local farmer for straw bales. Local farmers often have small bales for sale. 

Make sure you specify to the local farms that you are looking for straw, rather than hay bales. Also make sure that you request a small rectangle bale, rather than a large round bale.

If you are wanting straw for personal use, you’re going to have a difficult time transporting anything other than a small rectangle bale of straw.

What to do With Straw at the End of the Season

You might be wondering, straw is a great mulch, but what do I do with it at the end of the season? When your garden plants are nearing the end of the growing season, usually during late summer, or late fall, you can either remove the plants, or use the till method, and rototill your entire garden. 

You can leave the straw right in the garden when you rototill it. Leaving the straw in the garden actually serves great purposes because the straw will decompose and feed the soil before you plant again next year.

If you chose to use straw as mulch in flowerbeds where perennials are present, you can simply finish out the season with your perennial flowers and leave the straw in place. It may decompose over the winter, or it may sit right there and be ready for next year. 

For flowerbeds with annuals that need to be tilled under for next year, you can also leave the straw in place as you rototill, so that it combines with the dirt. Or you can remove the straw off the top of the soil and add it to your compost pile.

Using Straw as Mulch

There are many great uses for straw, apart from the typical use as an animal bed. Using straw as mulch in your vegetable garden, or even a flower bed, is a great idea, as it helps to prevent weeds from taking over, and also feeds the soil, and keeps it nice and moist. 

Hopefully, you have now been able to determine if you want to use straw as mulch, or if you want to try using a different type of mulch. Either way, happy gardening!
