Alfalfa food plot seed: full planting and management guide

Last updated 2026-07-24

What is a food plot and where does alfalfa fit in?

A food plot is a planted patch of forage on hunting or wildlife ground meant to feed deer and other game, usually somewhere between a quarter acre and several acres. Landowners plant them for two overlapping reasons: to add nutrition deer can't always find in the woods, and to create a spot where deer show up predictably enough to observe or hunt. Most food plot programs mix annuals and perennials. Annuals like oats, brassicas, and soybeans get replanted every year but grow fast and cheap. Perennials like alfalfa, clover, and chicory cost more to establish but keep producing for multiple seasons once they're in the ground. Alfalfa sits at the top end of the perennial tier. It's a legume, meaning it fixes nitrogen from the air through bacteria on its roots, and it's famous in the livestock world for protein content that beats almost anything else you can grow. The USDA's plant database lists alfalfa (Medicago sativa) as a perennial legume with deep taproots that can run several feet down, which is part of why it survives dry spells that kill shallower-rooted plots ^[1]. For deer hunters, alfalfa works best as a long-term investment plot, not a quick fix. If you want something in the ground and growing in six weeks, alfalfa isn't it. If you want a plot that deer hit hard for 4 to 5 years with good management, it's one of the better options out there.

Why do deer like alfalfa so much?

Deer key in on alfalfa because of the protein. Alfalfa forage regularly tests high in crude protein during the vegetative stage, well above what most native browse or even clover provides during summer stress periods, and university forage testing programs treat it as a benchmark high-protein hay and grazing crop for that reason ^[2]. That protein matters most from spring green-up through late summer, when does are lactating and bucks are growing antlers. A doe nursing twins has real nutritional demands, and a buck putting on inches of antler needs building blocks too. Alfalfa is often the first thing to green up in early spring and one of the last things standing before frost, which stretches its usefulness across a longer window than most other plantings. Deer also seem to just prefer it on taste and texture grounds once it's established. Anyone who's watched a healthy alfalfa field near dusk in July has seen how hard deer will hit it compared to surrounding cover crops. That's an observation, not a controlled study. The tradeoff is that alfalfa takes real management to keep it productive and free of weeds, and it can't tolerate wet feet or acidic soil the way clover sometimes can.

What soil and pH does alfalfa food plot seed actually need?

Alfalfa is the pickiest common food plot crop for soil chemistry. Land-grant extension programs consistently recommend a soil pH between 6.5 and 7.0 for alfalfa establishment, and yields drop noticeably below pH 6.0 because the nitrogen-fixing bacteria on alfalfa roots struggle in acidic soil ^[3]. Drainage matters just as much as pH. Alfalfa has a long taproot that hates sitting in standing water, and fields with poor drainage or a high water table are a poor match no matter how good the soil fertility looks on paper. If your plot holds water for more than a day or two after a heavy rain, alfalfa is probably the wrong call. A current soil test is the starting point, not a guess. Your soil test lab is the authority here, since regional recommendations vary and your lab's numbers reflect your actual dirt. Most labs will tell you exactly how much lime you need in tons per acre to hit that 6.5 to 7.0 range, and that number can vary widely depending on your existing pH and soil buffer capacity. Lime takes time to work. If your test comes back at pH 5.8, don't expect broadcast lime to fix that overnight; it can take 6 to 12 months for lime to fully react through the soil profile, which is one more reason alfalfa plots need planning a season ahead rather than a rush job in spring. For comparison, clover tolerates a slightly wider pH range and forgives some soil imperfection, while brassicas and cereal grains are far less picky overall. If your soil test comes back rough and you don't want to invest in heavy lime, that's a real signal to look at clover or a brassica blend instead.

When to plant food plots for deer, and where does alfalfa fit the calendar?

Northern (Zone 3-4)	Mid-April to late May	Not usually recommended (too little time before frost)
Transition (Zone 5-6)	Late March to April	Mid-August to early September
Southern (Zone 7-8)	March	September	These are general windows, not guarantees. Local frost dates and rainfall patterns shift them by a few weeks in either direction, and your state extension office publishes county-level planting date guidance that beats any national chart. Compare that to other common plot species. Turnips and other brassicas go in mid to late summer, generally 60 to 90 days before your first fall frost, since they need a full season to bulb up before deer start hitting them hard after a frost sweetens the greens. Oats for deer plots go in either early spring for a spring/summer grazing window or, more commonly, late summer into early fall (August through September in most of the whitetail range) so they're tender and green during hunting season [5].

Timing depends on your zone and the crop. As a general framework, cool-season perennials and cereal grains go in either early spring or late summer/early fall, while warm-season annuals like soybeans and sorghum go in late spring after frost risk passes. Alfalfa specifically is a spring or late-summer planting, and most extension guidance leans toward spring seeding in northern climates and late summer (roughly 6 to 8 weeks before the first killing frost) in transition and southern zones ^[4]. Spring planting gives the young stand a full growing season to establish a root system before winter. Late-summer planting works where fall moisture is reliable and the ground doesn't freeze too early. A rough national framework: | Region | Spring window | Late-summer window |

How do you plant alfalfa food plot seed step by step?

Start with the soil test, six months to a year ahead if you can manage it, so lime has time to adjust pH before planting. Skipping this step is the single most common reason alfalfa plots fail in year one. Once pH is corrected, prepare a firm, fine seedbed. Alfalfa seed is small, roughly 200,000 seeds per pound, and it needs good seed-to-soil contact at a shallow depth, generally a quarter inch to half inch deep ^[6]. Planting too deep is a classic mistake that kills germination rates. Most alfalfa seed sold for food plots comes pre-inoculated with the rhizobium bacteria that fix nitrogen, but if you buy raw seed, you'll need to inoculate it yourself before planting. Seeding rates for pure stands generally run 15 to 20 pounds per acre when drilled, or higher (20 to 25 pounds) when broadcast, since broadcasting has lower and less even germination ^[6]. A cultipacker before and after seeding helps a lot. Pressing the seed into firm contact with soil, rather than letting it sit loose on top or get buried too deep by a disk, makes a real difference in stand establishment. Weed control in year one is critical since young alfalfa can't compete with fast-growing weeds. Many plotters mix a small amount of oats or another nurse crop into the alfalfa seeding to suppress weeds and give some quick summer forage while the alfalfa establishes underneath, though this needs to be managed carefully so the nurse crop doesn't choke out the alfalfa itself.

How do you manage an established alfalfa plot?

Once alfalfa is established, the plot needs mowing or grazing pressure to stay in a vegetative, high-protein state. Left alone, alfalfa flowers and gets stemmy, and protein content drops as the plant matures. Mowing every 25 to 35 days during the growing season, or letting deer pressure keep it grazed down, helps keep new growth coming. Fertility upkeep matters every year, more than at planting. Alfalfa pulls phosphorus and potassium out of the soil heavily, and a maintenance soil test every 1 to 2 years will tell you what to add back. Nitrogen isn't usually needed since a healthy stand fixes its own, but P and K depletion is real and ongoing. Weed pressure and stand thinning are the two things that eventually end an alfalfa plot's life. Most well-managed stands hold up for 4 to 5 years before grass and weed encroachment or winterkill thin the stand enough that it's time to rotate to something else, often corn or beans, before coming back to alfalfa again a few years later. Winterkill risk is real in the northern part of the whitetail range. Alfalfa varieties differ in winter hardiness. Buying a variety rated for your zone matters more than most people realize when shopping; check the fall dormancy and winter survival ratings printed right on the seed tag.

Do deer eat sorghum, and how does it compare to alfalfa?

Yes, deer eat sorghum, particularly the grain heads once they mature and dry down in late summer and fall. Grain sorghum is planted as a warm-season annual, similar timing to corn, and it's valued in food plot mixes mostly as a fall and winter energy source plus standing cover, rather than as a high-protein summer forage like alfalfa. Sorghum is far more drought tolerant than alfalfa and grows on a wider range of soil types, which makes it a reasonable choice for sandy or marginal ground where alfalfa would struggle. But it doesn't offer anything close to alfalfa's season-long grazing value; sorghum is mostly a single-season annual played for its grain and cover, while alfalfa is a multi-year forage investment. If you're choosing between the two, the decision usually comes down to soil quality and what you want the plot to do. Marginal, well-drained ground that can't hold a 6.5 pH easily might be better suited to sorghum or another annual grain. Good bottomland or upland loam with solid drainage is where alfalfa earns its cost.

Do deer eat and like clover, and how does it compare to alfalfa?

Yes, clover is arguably the most consistently eaten food plot forage across the whitetail range, and deer show strong preference for it in study after study and in nearly every hunter's own trail camera pile. White clover varieties (Ladino, Durana, and others) and red clover are both heavily used in food plot blends. Clover and alfalfa are cousins in the legume family and share some traits: both fix nitrogen, both are perennials, both offer high protein. The differences matter for planning. Clover tolerates a slightly lower pH (many varieties do fine down to 6.0) and tolerates wetter, heavier soils better than alfalfa. Clover is also generally cheaper per acre and more forgiving of a mediocre seedbed. Alfalfa tends to out-produce clover in tonnage per acre on good ground and holds up better to drought thanks to its deeper taproot. But it's less forgiving of soil problems and costs more upfront. A lot of experienced plotters run a mix of both, or plant clover on the marginal acres and save alfalfa for the best-drained, best-tested ground on the property. If you're deciding between the two for a specific field, a food plot seed comparison guide can help match species to your soil test results rather than guessing.

When to plant oats for deer, and do they pair with alfalfa?

Oats for deer plots are usually planted in late summer to early fall, roughly August through mid-September across most of the whitetail range, so they green up and stay tender right through archery and firearm season ^[5]. A spring planting works too, mostly for early-season grazing before summer heat burns oats out, but fall planting is far more common in deer plot programs since oats handle cool weather well and deer show strong preference for them once frost sweetens the leaves. Oats pair with alfalfa in one specific way: as a nurse crop during initial alfalfa establishment. A light rate of oats mixed into a spring alfalfa seeding comes up fast, suppresses weeds, and gives deer something to eat while the alfalfa is still building its root system underground in the first few months. The oats get mowed or grazed off and don't persist, while the alfalfa carries the plot in following years. Outside of that nurse-crop role, oats and alfalfa are usually planted in separate plots rather than together long-term, since oats are an annual that needs replanting every year and alfalfa is a multi-year investment you don't want to disturb with annual tillage.

When to plant turnips for deer, and how does that compare to alfalfa's timing?

Turnips and other brassicas go in the ground in mid to late summer, typically 60 to 90 days ahead of the first expected fall frost in your area, which lands most of the whitetail range somewhere between late July and early September. Brassicas need that long runway to build root mass and leaf tonnage before frost, and deer usage often spikes hard after the first hard freeze converts starches to sugars in the leaves and bulbs. Compared to alfalfa, brassicas are a one-season annual play. You till, plant, and the crop is largely done after that season's deer pressure and winter kill it off; you're starting over next year. Alfalfa is the opposite: heavy upfront investment in soil prep and establishment, but multiple years of production afterward without replanting. Some property plans use brassicas as the fast, cheap fall attraction plot and alfalfa as the long-term summer nutrition plot, splitting acreage between the two rather than picking one over the other. That kind of split planning, matched to your specific fields and soil tests, is exactly the sort of decision a Custom Food Plot Plan is built to sort out for around $99 as a one-time cost, though the plan is general guidance built from your inputs, not a site visit or a guaranteed result.

What is a deer's favorite food, really, and does honey factor in?

There's no single scientifically settled answer to a deer's single favorite food, because preference shifts by season, region, and what's available locally. That said, agricultural crops and legumes consistently top preference studies and hunter observation: soybeans, corn, clover, and alfalfa show up again and again as heavily preferred forage across multiple regions, largely because of their protein and carbohydrate density compared to native browse ^[2]. Acorns deserve a mention too. In fall, deer in oak-heavy woods often shift hard to acorns over planted forage because of the fat and carbohydrate content, especially from white oak acorns which have lower tannin levels than red oak acorns and are more readily eaten. Do deer like honey? There's no real evidence deer seek out honey specifically, and it's not a practical or legal food plot input in most states anyway. Deer are occasionally drawn to sugary substances in general, which is part of why some hunters have historically used sweet baits or mineral licks, but honey isn't a documented or common part of wild deer diet studies, and using any bait or supplemental feed at all is regulated or banned outright in a lot of states. Baiting and feeding rules vary widely; some states allow it with restrictions on distance from stands or season timing, others ban it entirely for disease-control reasons like chronic wasting disease management. Check your state wildlife agency's current regulations before using any bait, mineral, or feed product, since rules change and enforcement is real.

Is alfalfa worth the cost compared to other food plot seed?

Alfalfa seed itself typically costs more per acre than clover, brassica, or cereal grain seed, and the upfront soil prep (lime, tillage, weed control) adds to that. But the multi-year production window changes the math. A well-managed alfalfa stand can produce forage for 4 to 5 years without replanting, while brassicas and oats need full reseeding every single year. Over a 5-year window, the annualized cost of alfalfa often lands lower than repeatedly replanting annuals, assuming the stand establishes well and the soil cooperates. The catch is that assumption is doing a lot of work. Poor drainage, low starting pH, or skipped maintenance fertility can shorten that lifespan considerably and blow up the cost math. The honest read: alfalfa is a good investment on your best-drained, best-tested acreage, and a poor investment as a first-try plot on ground you haven't soil tested. If you're planting your first food plot ever, clover or a brassica blend is usually the lower-risk starting point, with alfalfa as a second-year upgrade once you know your soil better. For a broader look at how alfalfa stacks up against other perennial and annual options side by side, the deer food plots overview and food plot whitetail guide both cover species selection in more depth.

Frequently asked questions

Do deer eat sorghum?

Yes. Deer eat sorghum, mostly the grain heads once they mature in late summer and fall. Grain sorghum works as a fall and winter energy source and standing cover in food plots, especially on drought-prone or sandy soils where alfalfa and other legumes struggle to establish.

Do deer eat clover, and do they actually like it?

Yes, deer eat clover readily and it's one of the most consistently preferred food plot forages across the whitetail range. Both white clover (like Ladino) and red clover show heavy deer usage, and clover tolerates a wider soil pH range than alfalfa, making it a more forgiving choice on average ground.

When should you plant food plots for deer?

Timing depends on species and region. Perennials like alfalfa and clover go in spring or late summer depending on zone. Brassicas like turnips go in mid to late summer, 60-90 days before first frost. Oats usually go in late summer to early fall. Check your state extension office for local frost dates and county-level guidance.

Do deer like clover more than alfalfa?

Both are heavily eaten legumes and preference studies don't show a clear universal winner. Alfalfa often out-produces clover in tonnage on good, well-drained ground and holds up better in drought, while clover tolerates wetter or more acidic soil and costs less to establish. Many plotters run both.

When should you plant oats for deer food plots?

Most food plot programs plant oats in late summer to early fall, roughly August through mid-September, so they're green and tender through hunting season. A spring planting works too for early-season grazing before summer heat burns the crop out, but fall is far more common.

When should you plant turnips for deer?

Plant turnips and other brassicas 60 to 90 days before your area's first expected fall frost, which lands most of the whitetail range between late July and early September. Deer usage often increases sharply after the first hard frost sweetens the leaves and bulbs.

What exactly is a food plot?

A food plot is a planted area, usually a quarter acre to several acres, seeded specifically to feed deer or other wildlife and to draw them somewhere predictable for observation or hunting. Plots mix annual crops (oats, brassicas, soybeans) with perennials (clover, alfalfa, chicory) depending on goals and budget.

What is a deer's favorite food overall?

There's no single settled answer since preference shifts by season and region, but agricultural legumes and grains like soybeans, corn, clover, and alfalfa consistently top preference observations because of their protein and carbohydrate density. Acorns, especially white oak, are heavily preferred in fall when available.

Do deer like honey?

There's no solid evidence deer specifically seek out honey, and it's not a documented part of wild deer diet research. Honey also isn't a practical or often legal food plot or bait input. Many states restrict or ban baiting and supplemental feeding outright, so check your state wildlife agency's current rules before trying any sweet bait.

What soil pH does alfalfa food plot seed need?

Alfalfa needs a soil pH between 6.5 and 7.0 for good establishment, according to land-grant extension guidance. Below pH 6.0, the nitrogen-fixing bacteria on alfalfa roots struggle and yields drop noticeably. A current soil test and enough lime to correct pH, applied months ahead of planting, are essential first steps.

How long does an alfalfa food plot last before it needs replanting?

A well-managed alfalfa stand typically produces for 4 to 5 years before weed encroachment, stand thinning, or winterkill make replanting worthwhile. Maintenance soil testing every 1-2 years and mowing every 25-35 days during the growing season both help extend productive stand life.

Can you plant alfalfa and clover together in the same food plot?

Yes, alfalfa and clover mixes are common and both legumes complement each other well; clover fills in thin spots and tolerates slightly wetter or more acidic patches within a field, while alfalfa dominates on the better-drained, higher pH areas. Many food plot seed blends are sold specifically as alfalfa-clover mixes.
