Quick answer: Coastal bermudagrass is the warm-season workhorse that thrives in summer heat right where cool-season grasses quit. The single biggest lever on quality is cutting interval: a roughly 28-day cut runs about 19% crude protein, while stretching to 42 days drops to around 12% but yields more tonnage. Feed it 40–50 lb of nitrogen per ton of expected yield, establish hybrids from sprigs (not seed), take the last real cutting before fall frost pulls feed value into the roots, and bale it leaf-on around 15–18% moisture with full net wrap to lock in the leaf you grew.
If you farm anywhere from the mid-South to the Gulf, coastal bermudagrass is probably the most productive hay you can grow. It loves the heat, regrows fast after each cutting, tolerates grazing and traffic, and — once established — a good stand lasts for decades. The trade-off is that bermuda hay quality is entirely in your hands: it is set by how often you cut and how much nitrogen you feed. Get the interval right and you make 19% protein horse hay; let it get away and you bale "lumber." Here is how experienced growers dial it in.
A grass built for the heat
Bermuda is a warm-season perennial, which makes it the mirror image of cool-season grasses like orchard grass or fescue. It does almost nothing in cool spring and fall, then explodes through the hot months that shut those other grasses down. One grower on the northern fringe of bermuda country laid out the trade cleanly:
"The bermuda will be opposite of the orchard since it will grow the best in the hot summer months and very little in the cooler spring and fall... The upside is once you have a stand of bermuda established it will last a really long time while orchard will start thinning and need replanting every 4-5 year or so."

That durability is why growers in marginal areas keep pushing the crop north:
"Im becoming more and more convinced that Bermuda grass might be the best grass for this area to make hay out of."

The cutting-interval / protein trade-off (the heart of bermuda hay)
This is the decision that defines your hay. The most useful explanation we found came from a Texas grower who has clearly run the numbers:
"There is a lot of misinformation regarding protein and harvest interval. If the bermudagrass has been fertilized with 40 to 50 lbs/A of nitrogen per ton of expected yield. Then cutting at 28 days will result in roughly 19% CP."
— hay wilson in TX, near Temple, Texas · HayTalk thread 11254
Stretch the interval and protein falls in a predictable way. Pulling together the forum numbers (which line up with university extension data from Texas A&M, Mississippi State, and others):
| Cutting interval | Typical crude protein | Best for |
|---|---|---|
| ~21 days | 22–26% (contest hay) | Maximum quality, minimum tonnage |
| ~28 days | ~19% | Premium horse hay; common research standard |
| ~35 days | ~15% | Balanced quality and yield |
| ~42 days | ~12% | Beef cattle; strong tonnage |
| 49+ days | ~10% | Maximum tonnage, lowest quality |
So which is "right"? It depends on your market. For beef cows, chasing contest protein is wasted money:
"To my thinking bermudagrass is about optimal at 12% CP. You can feed that & not require supplemental protein."
— hay wilson in TX · HayTalk thread 11254
And there is a yield cost to short intervals that growers chasing a protein number tend to forget:
"There is always going to be a tradeoff between quality and quantity harvested. Surely one can get 20% CP from a given acre but how many pounds of CP did you harvest from that acre? Likely, not too much."
— bunchgrass1 · HayTalk thread 11254
The practical takeaway: pick your interval from your customer, not from bragging rights. Horse and dairy-replacement buyers pay for the 28-day, 18–19% hay; beef operations are well served by a 35–42 day cut. Our guide on how to price hay covers how to turn that protein test into the right asking price.
Nitrogen drives both yield and protein
Bermuda is a nitrogen pump — it returns roughly what you feed it. The working rule from the same Texas grower is 40–50 lb of N per ton of expected hay, split across the season and applied after cuttings. Push protein higher and the nitrogen bill rises fast: 19% CP hay represents on the order of 60–65 lb of nitrogen per ton, while contest-grade 22–26% hay can run 85 lb of N per ton. Always soil-test first, because nitrogen only pays when potash, phosphorus, and pH are not the limiting factor — short potash going into summer is a classic way to waste your nitrogen and weaken the stand.
Sprigs vs. seed: establishing the stand
This is where bermuda demands more than orchard grass. The high-yield hybrid bermudas — Coastal, Tifton 85, Midland 99 — are sterile and must be planted from live sprigs (rhizomes), not seed. Only common and a handful of seeded types come from a bag. A grower weighing a hybrid for hay summed up the catch:
"The downside to bermuda is it is going to be more difficult for me to establish since you have to use live sprigs instead of seeds to establish a stand and sprigs aren't readily available here and more costly to buy than orchard grass seeds."
— FarmerCline · HayTalk thread 24990
If sprig diggers are scarce in your area, growers have had luck propagating from mature top growth:
"Most hybrid Bermudas, but not all, will propagate from tops clipped off of a field and immediately run coulter or disc over it.....Bermuda needs to be mature.....very effective if no spriggers are nearby."
— somedevildawg, Georgia · HayTalk thread 40297
On variety, the newer cold-tolerant hybrids have opened bermuda to growers farther north:
"You may want to look at midland99 it is the newest hybrid out and is pretty cold tollarant."
— Ranger518 · HayTalk thread 95864
One myth worth clearing up: hybrid bermuda does not "revert" to common. What growers see as reversion is almost always common bermuda or weedy grass creeping into a thin, under-fertilized, or scalped stand. Keep the hybrid vigorous with fertility and proper cutting height and it stays dominant.
Pests and end-of-season timing
Two summer pests can wreck a bermuda cutting fast: fall armyworms, which can strip a field almost overnight, and the bermudagrass stem maggot, which browns the top growth. Scout after every cutting through late summer — growers in one thread were treating for armyworms multiple times in a single season while also fighting stem maggots and billbugs (HayTalk thread 52825). A standing crop you planned to bale next week is worth checking twice.
Timing the last cutting matters too. Once fall sets in, the plant moves its energy below ground and quality slides:
"Here, near Temple Texas I like to cut bermudagrass before 8 October as after then most of the growth carbohydrates is going to the roots."
— hay wilson in TX · HayTalk thread 15380
Take your last quality cutting roughly 4–6 weeks before your average first frost so the stand can store reserves for winter. The exception is Tifton 85, which holds feed value as standing or stockpiled forage better than Coastal does.
Cutting, drying, and baling bermuda right
Bermuda's value is in its leaf, and leaf is what you lose if you bale it wrong. It cures faster than a thick legume but still wants conditioning and, in humid weather, tedding — see how to make dry hay faster. Rake gently and at the right moisture to keep leaf attached rather than shattering it onto the ground; a well-set rake earns its keep here. Bale dry bermuda hay around 15–18% moisture — our baling-moisture guide details the targets and the heating risk above them.
Then protect it. A bermuda round bale is a tightly packed, leafy, valuable package, and full edge-to-edge bale net wrap sheds rain, holds the bale's shape through stacking and hauling, and cuts the weathered outer layer compared with twine — which matters most for the bales you store outside (see storing net-wrapped bales outside). When you have spent a season metering nitrogen and timing cuttings to hit a protein number, net wrap is the cheap insurance that keeps that quality in the bale until it is fed or sold.
Coastal bermuda hay, start to finish
- Establish from sprigs for hybrids (Coastal, Tifton 85, Midland 99); seed only common or seeded types.
- Feed 40–50 lb N per ton of expected yield, after soil-testing for potash, phosphorus, and pH.
- Set your cutting interval by market — ~28 days for ~19% horse hay, ~35–42 days for beef-grade tonnage.
- Scout for armyworms and stem maggot after every cutting; take the last quality cut before fall frost.
- Bale leaf-on at 15–18% and net-wrap to protect the protein you grew.
Frequently asked questions
How does cutting interval affect bermuda hay protein?
Cutting interval is the main driver of bermuda hay protein. A roughly 28-day interval with adequate nitrogen produces around 19% crude protein, while stretching to about 42 days drops it to near 12% but yields more tonnage. Shorter intervals raise quality and lower yield; longer intervals do the reverse. Match the interval to your market rather than chasing a number.
How much nitrogen does coastal bermuda hay need?
A common rule of thumb is 40 to 50 pounds of nitrogen per ton of expected hay, split across the season and applied after cuttings. Higher protein targets require more: roughly 60 to 65 pounds per ton for 19% crude protein. Always soil-test first, because nitrogen only pays off when potash, phosphorus, and pH are not limiting growth.
Can you plant coastal bermuda from seed?
The high-yield hybrid bermudas such as Coastal, Tifton 85, and Midland 99 are sterile and must be established from live sprigs, not seed. Only common bermuda and a few seeded varieties can be planted from a bag. Hybrids cost more to establish and need sprigs, but a healthy stand can remain productive for decades, which usually outweighs the higher setup cost.
When should you stop cutting bermuda in the fall?
Take your last quality cutting about 4 to 6 weeks before your average first frost so the stand can store root reserves for winter. Many Southern growers aim to finish by early October, since after that the plant moves carbohydrates to the roots and feed value drops. Tifton 85 is an exception, holding quality better as stockpiled standing forage.
What moisture should you bale bermuda hay at?
Bale dry bermuda hay at about 15 to 18% moisture. Bermuda cures faster than thick legume hay, but its value is in the leaf, so condition at cutting and rake gently to avoid shattering leaf. Baling much wetter without a preservative risks heating and mold; net-wrapping the finished bale then protects quality through handling and outdoor storage.
