Buy straw at garden centers, farm supply stores, and online retailers

Straw for grass seed is sold at most places that carry gardening supplies. Your nearest garden center, home improvement store, or farm supply shop will stock it during spring and early summer—the peak seeding season. If you need straw outside those months or in large quantities, online retailers like Amazon and specialty farm suppliers ship nationwide. Local farm co-ops and feed stores often have the best prices and can advise you on what works in your region.

The type of straw matters more than where you buy it. Wheat straw and oat straw are the standard choices for grass seed. Avoid hay, which contains weed seeds that will sprout alongside your grass. Straw is the hollow stem left after grain is harvested—it has no seeds. Hay is dried grass and legumes cut for animal feed, and it will undermine your seeding effort.

Key Takeaways

  • Garden centers, home improvement stores, and farm supply shops carry straw year-round, with the best selection in spring and early summer.
  • Buy wheat straw or oat straw, never hay, because hay contains weed seeds that will compete with your new grass.
  • Farm co-ops and feed stores usually offer lower prices than garden centers and can tell you which straw type performs best locally.
  • Online retailers ship straw, but shipping costs are high because straw is bulky; compare the total price to local pickup before ordering.
  • One bale covers roughly 1,000 square feet when spread thin, so measure your seeding area to know how many bales to buy.

Garden centers and home improvement stores

Big-box stores like Home Depot and Lowe's stock straw in their garden sections from March through June in most regions. Prices typically run $5 to $10 per bale, though they may charge more during peak season. The advantage is convenience—you can pick it up the same day and inspect the bales for mold or excessive dust before buying.

The downside is that these stores often have limited selection. You may find only one or two types, and staff may not know the difference between straw and hay. Bring a photo of straw on your phone if you are unsure, or ask to see the stems—straw should be hollow and seedless, while hay will show dried plant material and seeds. If the store is out of stock, ask when the next delivery arrives rather than settling for hay.

Farm supply stores and agricultural co-ops

Farm supply retailers and local agricultural co-ops are your best source for quality and price. These businesses sell straw year-round because farmers use it for animal bedding and mulch. Prices are usually $3 to $7 per bale—significantly lower than garden centers—and staff understand the difference between straw and hay. They can also tell you which type works best for your soil and climate.

To find a co-op near you, search "agricultural co-op near me" or "farm supply [your town]." Call ahead to confirm they have straw in stock and ask about bulk discounts if you need more than five bales. Many co-ops will load bales into your truck if you ask. Some also deliver for a fee, which may be worth it if you need a large quantity and do not have a truck.

Online retailers and bulk suppliers

Amazon, Tractor Supply, and specialty farm retailers ship straw nationwide. Prices per bale are competitive—often $4 to $8—but shipping costs are steep because straw is bulky and light. A single bale may cost $15 to $25 to ship, depending on your location. Order only if you need straw urgently and have no local source, or if you are buying in bulk (10+ bales) and the per-unit cost after shipping is lower than local prices.

When ordering online, read the product description carefully. Some sellers specify the straw type; others do not. Look for reviews mentioning whether the straw arrived clean and free of mold. Straw that sits in a warehouse or shipping container can develop mildew, which will not harm your grass but may indicate poor storage. Request a photo from the seller if the listing does not show the actual product you are receiving.

Calculating how much straw you need

One standard bale covers roughly 1,000 square feet when spread at a thickness of one-quarter to one-half inch. Measure your seeding area in feet—length times width—and divide by 1,000 to find the number of bales. For example, a 50-by-40-foot lawn is 2,000 square feet, so you need two bales.

Spread straw thin enough that you can still see soil underneath. If you cover the soil completely, you are using too much, and the straw will mat down and trap moisture. The goal is to shade the seed and keep it from drying out, not to create a thick blanket. Buy one extra bale to account for waste and uneven spreading—it is easier to use leftover straw as mulch than to run out halfway through.

Timing your purchase

Buy straw one to two weeks before you plan to seed. Straw stored indoors or under cover stays dry and clean. If you buy too early and store it outside, rain and humidity can cause mold or sprouting. If you buy too late, garden centers may be out of stock, and you will be forced to choose between waiting for a restock or buying hay by mistake.

Spring (March to May) and early fall (August to September) are the best times to seed cool-season grasses in most of the country. Straw availability is highest during these windows. If you are seeding in summer or winter, call ahead to confirm stock, because many retailers reduce their straw inventory during off-season months.

Checking quality before you buy

Inspect bales in person if possible. Look for straw that is golden or tan in color, with hollow stems and no visible seeds. Squeeze the bale—it should feel dry and not smell musty. If it smells like mold or feels damp, do not buy it. Moldy straw will not harm your grass, but it indicates poor storage and may contain fungal spores that slow germination.

Avoid bales that are heavily compressed or have visible hay mixed in. Hay looks different: it has a finer texture, visible seed heads, and a sweeter smell than straw. If you are unsure, ask the seller to show you the difference, or take a photo to compare with online images of straw versus hay. One wrong bale can introduce hundreds of weed seeds into your lawn.

Frequently Asked Questions

Can I use hay instead of straw for grass seed?

No. Hay contains weed seeds that will sprout alongside your grass and compete for water and nutrients. Straw is the hollow stem left after grain harvest and contains no seeds. Using hay will undermine your seeding effort and create extra weeding work later.

How long can I store straw before using it?

Straw stored indoors or under a tarp stays usable for several months. Store it in a dry place away from direct sunlight and moisture. If you store it outside uncovered, rain and humidity will cause mold within weeks. Buy straw one to two weeks before seeding to keep it fresh.

What if the garden center only has hay?

Leave and try another store. Hay will introduce weeds into your lawn and is not worth the savings. Call farm supply stores or co-ops in your area—they almost always stock straw year-round. If no local source has it, order online, but factor in shipping costs before deciding.

Do I need to remove straw after the grass grows?

No. As your grass grows, it will push through the straw. The straw breaks down over several weeks and adds organic matter to the soil. You do not need to rake it out. If straw remains visible after the grass is established, you can rake it out, but it is not necessary.

Is there a difference between wheat straw and oat straw?

Both work for grass seed. Wheat straw is slightly coarser and more common. Oat straw is finer and breaks down faster. Either one will protect your seed and keep it moist. Ask your local farm co-op which is more available in your area—availability matters more than the type.
