Using straw as mulch in the garden saves money, crops, and sanity. (Note: Straw is not hay.) See the many benefits of mulching with straw bales in the vegetable garden.
No, I鈥檓 not Rumpelstiltskin, the cranky gnome in a Grimm fairy tale; I can鈥檛 spin straw into gold. But straw bales are inexpensive gold for gardens. I only pay $4 a bale, and the straw saves me hours of weeding, watering, and worrying. I get it from a farmer nearby. Numerous garden centers stock straw, too. Bales are huge; one will usually cover the garden. Just be sure that you are buying straw, not hay.
Everything in the vegetable garden is mulched with a 6-inch layer, including blueberries, Alpine strawberries, and cranberries. I use a foot or two of straw atop the potato bed to grow clean potatoes that can be easily harvested. Tubers form in the straw, and crops are always bigger when I use the straw mulch.
First, let me explain that straw is not hay. You don鈥檛 want to use hay, as it will cause nightmares and plenty of weed pulling. Hay is a grass that is primarily grown and cut for livestock. It is difficult to cut hay without at least some of the grass going to seed.
Straws are the dry hollow hay stalks remaining after cereal crops such as wheat or barley have been harvested. They contain few or no seed heads, especially when compared to hay鈥 (University of Maryland Extension Service). Straw stalks don鈥檛 compact or mat. They鈥檙e also slow to decompose and don鈥檛 tie up nitrogen or other nutrients in the soil, making the perfect mulch.
Straw Lets You Water Less Often
A thick blanket of straw keeps the moisture in the soil, radically slowing evaporation. Watering the garden once a week will be the norm rather than every day or two. They dry out a lot slower in hot, sunny weather.
If you live in an area of the country experiencing a rainfall shortage this summer or drought, straw mulch is gold! I do. We鈥檝e received only a tenth of normal rainfall and had a huge snow shortage last winter. The ground is so dry that it鈥檚 cracking in spots. But despite high temperatures and a lack of rain, I water the vegetable garden only once a week.
Straw Mulch Reduces Weeds
Straw blocks out the sun, preventing most weeds from germinating and growing. First, remove the weeds from your garden bed. Then, lay down the straw immediately.
If you鈥檝e already seeded your vegetables, don鈥檛 lay straw on top of the seeds or seedlings. But everywhere else, there is exposed ground; lay down a nice thick layer of straw
It will not only keep weeds from growing but also keep the soil moist, soft, and workable.
Straw Mulch Reduces Pests and Diseases
Straw also saves crops like tomatoes, peppers, and squash from developing blossom-end rot and cat-facing, blueberries from shriveling, and sweet peppers from turning hot.
Soil moisture stays even, and calcium can be transferred from the soil to tomatoes easily, preventing diseases.
Straw mulch at the base of tomato and pepper plants also prevents the transfer of soil-borne diseases such as early blight to plant leaves. No water splashes up from the soil to the leaves because the straw absorbs it.
A thick straw mulch also fosters the growth of large pumpkins, winter squash, and watermelons. The mulch provides a clean blanket upon which melons and pumpkins can grow unblemished.
Straw Mulch Increases Nutrients in the Soil
Straw decomposes like any other organic material, but it鈥檚 much slower. As straw rots, it releases nutrients, feeding the plants growing in it. Straw actually makes your garden better. Genius, right?
Have you used straw for mulch? What other materials do you use to hold moisture in and prevent diseases?

i covered my garden in straw over the winter...its almsot a foot deep. the soils gotten pretty compacted underneath. should i pull the straw back and till? or should i plant right in the straw? thanks
Hi, Julie鈥 Based on Doreen’s advice (above), esp in the context of her dry soil, we would say plant! And water accordingly (she experienced dry soil, too). The straw will break down over time.
Most thistles can be controlled with the use of herbicides in the fall or spring. You do need to figure out what type of thistle you have ( there are both perennial and biennial kinds) to figure out the best solution. We'd suggest you contact your local county cooperative extension to recommend herbicides approved in your state.
Following up on TimCAD's Q&A...I have just directly sowed many seeds...lettuce, carrots, green beans, peas... and have added a 1"-ish layer of straw as mulch. In your answer, are you suggesting NOT to use straw as mulch at this point, but to wait til I have growth, and then add straw? If so, what do you suggest I use as mulch? I live in a very dry area and want to use something for water retention. Thanks.
