Planting food plots in September: the full timing guide

Last updated 2026-07-26

Why is September the biggest month for food plot planting

September carries more food plot planting activity than any other month because it lines up with the last safe planting window before frost for brassicas and small grains, and it's early enough that clover and perennial mixes can still root before winter. If you only had one month to plant, most extension agronomists and habitat biologists would tell you to make it this one. The catch is that September in Minnesota and September in Alabama are not the same planting season at all. Soil temperatures, first frost dates, and rainfall patterns shift by six to eight weeks across the whitetail's range, so a calendar date means almost nothing without a zone attached to it. The USDA Plant Hardiness Zone Map is the standard reference for splitting the country into workable bands, and most food plot calendars borrow its zone logic even though it was built for perennial landscaping, not deer forage. A rough three-zone way to think about it: Zone 3-4 (the Upper Midwest, northern New England, higher elevations) needs brassicas and clover in the ground by the first two weeks of September or earlier. Zone 5-6 (much of the Midwest, mid-Atlantic, Ohio Valley) has through mid-to-late September for most plantings. Zone 7-8 (the Deep South, southern Plains) should hold off on brassicas and clover until late September into October, because summer heat and drought stress will kill young seedlings that germinate too early. If you want a plan built around your actual coordinates and soil test instead of a generic zone map, that's the exact gap a Custom Food Plot Plan is built to close for $99. It won't replace your soil test lab's lime and fertilizer recommendations, but it will translate zone, species, and timing into a real calendar for your property.

When to plant food plots for deer, by region

Zone 3-4 (Upper Midwest, N. New England)	Aug 1-20	Aug 15-Sept 10	Aug 15-Sept 5
Zone 5-6 (Mid-Atlantic, Midwest, Ohio Valley)	Aug 15-Sept 10	Sept 1-25	Aug 20-Sept 20
Zone 7-8 (Deep South, southern Plains)	Sept 15-Oct 15	Oct 1-Nov 1	Sept 15-Oct 30	These windows come from land-grant extension planting guides such as Penn State Extension's food plot publications and Mississippi State University Extension's deer forage guidance, both of which stress matching planting date to regional frost timing rather than a fixed calendar date [2].

The honest answer is: it depends on your frost date and your species, but here's the working framework most state wildlife agencies and extension programs use. For fall annual plots (brassicas, turnips, oats, winter wheat, winter rye), the target is roughly 60 to 90 days before your average first killing frost, so the plants have time to establish before growth slows. The National Weather Service and NOAA Climate Normals track average first frost dates by station, and that's the number to check for your county, not a national planting chart ^[1]. For perennial clover and alfalfa, September plantings work in the northern two-thirds of the country specifically because soil is still warm enough for germination but the heat and weed pressure of July and August have passed. This is sometimes called a 'dormant-adjacent' planting, not because the seed goes dormant immediately, but because growth slows fast enough after establishment that weed competition is lower than a spring planting. Here's a simplified zone table. Treat it as a starting point, then check your local frost date. | Region (USDA zone) | Brassicas/turnips | Oats/cereal grains | Clover |

When to plant turnips for deer

Turnips go in the ground 80 to 90 days before your first expected hard frost, which for most of the Midwest and mid-South lands somewhere between late July and early September. Plant later than that and the bulbs won't have time to size up before cold weather locks in the sugars deer are after. Turnips are a strange case because deer often ignore the leaves and tops early in the season, then hammer the whole plant, bulb included, after the first hard frosts convert starches to sugars. That's why a lot of hunters see a turnip plot sit untouched in October and get pounded in December. Mississippi State University Extension's food plot guidance notes this cold-triggered palatability shift as one of the main reasons brassica plots peak late in the season rather than at planting ^[2]. Seeding rate for turnips alone runs about 4 to 6 pounds per acre when broadcast, lighter than most people guess. Overseeding at double that rate wastes seed and doesn't improve tonnage; it just crowds bulb development. If you're blending turnips with other brassicas or cereal grains, cut the turnip rate to 2 to 3 pounds per acre in the mix.

When to plant oats for deer

Oats go in 6 to 8 weeks before your first fall frost so they can reach a good leaf stage before growth stops, which usually lands in the September window across most of the whitetail's range, sliding into early October in the Deep South. Oats are one of the most forgiving fall annuals because they establish fast and green up within a week or two of a decent rain. Oats also die completely at the first hard freeze in most regions (they're far less winter-hardy than winter wheat or cereal rye), so they function as an early-to-mid fall attractant, not a season-long food source. If you want green forage into late winter, pair oats with winter wheat or cereal rye in the same mix; the oats provide fast early tonnage while the wheat or rye carries the plot through winter and into spring green-up. Seeding rate for oats alone is typically 2 to 3 bushels (about 64 to 96 pounds) per acre broadcast, per standard cereal grain seeding guides used by university extension forage programs. Drilled rates run lower, closer to 1.5 to 2 bushels per acre, because drilling gets far better seed-to-soil contact than broadcasting.

What is a food plot, exactly

A food plot is a planted area of forage crops, on land you own or lease, managed specifically to attract and feed deer or other wildlife rather than to produce a commercial harvest. Plots range from a quarter-acre kill plot tucked into timber to multi-acre destination fields planted in clover, brassicas, or cereal grains. Food plots serve two overlapping purposes: nutrition (helping deer, especially does and growing bucks, meet energy and protein needs through stress periods) and hunting access (concentrating deer activity somewhere you can hunt them safely and effectively, downwind of a stand or blind). Most state wildlife agencies treat food plots as a habitat management tool, distinct from baiting, though the legal line between the two varies a lot by state. That legal distinction matters. Many states define a food plot as a standing, planted crop and treat it differently from bait piles of harvested grain, minerals, or feed placed on the ground. Michigan, for example, prohibits baiting and feeding of deer in the Lower Peninsula in most circumstances but explicitly allows standing food plots as a land management practice ^[3]. Other states, like parts of Wisconsin's CWD-affected counties, restrict baiting and feeding for disease control reasons that don't apply to plots but that hunters sometimes confuse with plot restrictions ^[4]. Always check your state wildlife agency's current regulations before assuming a practice is legal; rules change year to year, especially around chronic wasting disease zones.

Do deer eat clover, and do deer actually like it

Yes, clover is one of the most consistently preferred food plot forages across the whitetail's range, and deer will use it from spring green-up through fall in most climates. It's also one of the most forgiving perennial plantings for a first-time plot planter because it's tolerant of a range of soil types once pH is corrected. Whitetail deer research and extension forage trials consistently rank clover among the highest-preference plot species, largely because of its protein content. Ladino and red clover typically run 25 to 30% crude protein in vegetative growth stages, comparable to or higher than soybeans in early growth, according to forage quality data compiled by university agronomy programs ^[5]. That protein level matters most in spring and summer for antler growth and lactation, but clover keeps producing into fall as long as moisture holds. The tradeoff is patience and soil chemistry. Clover needs a soil pH close to 6.0 to 6.5 to perform well and it responds hard to lime corrections; a soil test is the only honest way to know if your field needs it, and how much. Plots seeded into acidic soil without lime often look thin and get out-competed by weeds in year one, which gets blamed on the seed when it's really a pH problem.

Do deer eat sorghum

Yes, deer eat grain sorghum (milo), both the standing seed heads and, to a lesser degree, the foliage, but it typically ranks behind corn, soybeans, and brassicas in deer preference trials. Sorghum's real value in a plot mix is usually as a screening and structure crop or a drought-tolerant grain option in the southern Plains and Deep South, not as a top-choice attractant. Sorghum tolerates heat and low rainfall better than corn, which is why it shows up more often in food plot mixes across Texas, Oklahoma, and the southern Great Plains where corn struggles without irrigation. Texas A&M AgriLife Extension recommends grain sorghum as a supplemental deer forage option specifically in drier regions where corn yields are unreliable, while noting deer generally prefer other available forages when they have a choice ^[6]. If sorghum is your only standing grain in a plot come late fall and deer have nothing better, they'll use it hard, especially after frost softens the seed heads. But if you're planting it hoping to outcompete a neighboring soybean field, temper expectations.

What are deer's favorite foods, and where does that leave food plots

There's no single universal favorite; deer preference shifts by season, region, and what's locally available, but soybeans, clover, and standing corn consistently rank at or near the top of preference studies across the whitetail's range, alongside acorns when they're on the ground. Brassicas and turnips climb the preference list hard after the first frost, when cold converts starches to sugars. Acorns deserve their own mention because in years with a good mast crop, deer will often abandon food plots entirely for a few weeks to hammer white oak acorns, which are lower in tannins and more palatable than red oak acorns. Wildlife biologists with several state agencies note this mast dependency is one of the biggest variables in whether a plot gets hit hard in October, and it's mostly outside a landowner's control season to season. Soybeans in particular show up near the top of nearly every deer forage preference ranking, largely due to protein content in the 30-40% range during the vegetative stage, similar to clover ^[5]. The catch with soybeans is that they can't handle heavy browse pressure as seedlings; on smaller properties with high deer density, beans often get grazed to the dirt before they can establish, which is why a lot of small-acreage plotters lean on brassicas and cereal grains instead, since those tolerate some early browsing better.

Do deer like honey (and does it belong in a food plot)

Deer don't eat honey in any meaningful field sense, and it's not a food plot input in any legitimate agronomic guidance. This question shows up because of scent-based deer attractant products that use sweeteners, molasses, or honey-based compounds as lures, separate entirely from planted forage. Worth being direct here: those products are attractant and scent lures, not food plot inputs, and their use is governed by baiting and feeding regulations in many states, the same rules that govern corn piles and mineral licks. Check your state wildlife agency's baiting definition before using any scent, mineral, or feed-based attractant, because what counts as 'baiting' varies enormously. Some states define bait as any placed food or mineral substance regardless of quantity; others allow small mineral use but ban grain. If you want deer on sweet forage, plant standing brassicas or a clover/chicory blend instead. That's legal everywhere as a planted crop and it actually feeds deer instead of just luring them.

How do soil tests and fertility fit into a September planting plan

A September planting only works if the soil chemistry is already close to right, because there isn't time left in the season to fix a bad pH before the crop needs it. Ideally, lime goes down in spring or even the prior fall, since agricultural lime can take 3 to 6 months to fully react with soil and shift pH, according to soil fertility guidance from land-grant extension programs. If you're testing soil for the first time in September, don't skip it just because the timing is late. Apply the recommended lime anyway (it'll keep working into next year even if this year's crop doesn't fully benefit), and lean on starter fertilizer and a forgiving species like oats or winter rye that tolerate a wider pH range than clover or alfalfa. Your soil test lab's report is the actual authority here, not a generic blog rule of thumb. Labs calibrate lime and fertilizer recommendations to your specific soil type, current pH, and target crop, and that report should always override a general planting guide, including this one, when the two disagree.

What equipment do you actually need for a September planting

At minimum: a way to kill or suppress existing vegetation (herbicide and a sprayer, or disking), a way to get seed-to-soil contact (a drill, a cultipacker, or just dragging a chain harrow after broadcasting), and a way to apply lime and fertilizer if your soil test calls for it. For small plots under an acre, a broadcast spreader, a hand or ATV-mounted sprayer, and a drag harrow will get you through most brassica, oat, and clover plantings without a tractor. For plots over a few acres, a no-till drill saves seed and improves germination rates significantly over broadcasting, especially for small-seeded species like clover, which needs to sit near the surface, not buried. One September-specific equipment note: if you're planting into standing summer weeds or a spent spring plot, glyphosate needs 5 to 7 days of active growth to translate through the plant before a killing frost shuts everything down. Spraying too late in September in northern zones means the herbicide won't work well, and you'll fight weeds all fall. Get burndown done early in the month if there's any frost risk at all.

Building a September planting checklist for your zone

Start with your county's average first frost date from NOAA climate normals, then count backward: 80-90 days for turnips and brassicas, 60-75 days for oats and cereal grains, and roughly 45-60 days minimum for clover to establish enough root reserve before winter dormancy ^[1]. A basic September sequence for a mid-latitude property (Zone 5-6) might look like this: soil test result reviewed and lime applied if needed by early September, burndown herbicide applied 7-10 days before planting, brassica/turnip blend or oat/clover mix drilled by mid-September, and a follow-up check for weed pressure or deer browse damage two to three weeks after emergence. If you're planting multiple plot types across a property (a destination clover field plus a few brassica kill plots), stagger the work so brassicas and turnips go in first (they need the longer runway) and clover or oat overseeding follows once the bigger planting is done. This is exactly the kind of multi-plot sequencing a Custom Food Plot Plan lays out species by species for $99, built around your zone and soil test rather than a one-size-fits-all calendar.

Frequently asked questions

Is September too late to plant a food plot?

Not usually, but it depends heavily on species and zone. Brassicas and oats can still go in through mid-to-late September in most of the country. Clover has a narrower window and needs 45-60 days before hard frost to establish root reserves. In the Deep South, September is often still too early because of summer heat stress.

What is the best food plot to plant in September?

A brassica/turnip blend paired with oats or winter wheat is the most reliable September combination for most zones. Brassicas provide late-season tonnage after frost sweetens them, oats give fast early growth, and a cereal grain like wheat or rye carries the plot into winter after the oats die back.

Do deer eat sorghum in food plots?

Yes, deer eat grain sorghum, particularly the seed heads after frost softens them, but it typically ranks below corn, soybeans, and brassicas in preference. It's most useful in hot, dry regions like the southern Plains where corn struggles, per Texas A&M AgriLife Extension guidance.

Do deer like clover more than other food plot options?

Clover consistently ranks among the top-preferred food plot species because of its high crude protein, often 25-30% in vegetative growth. Deer use it from spring through fall in most climates, though soybeans and standing corn can rank equally high depending on season and region.

When should I plant turnips for deer specifically?

Plant turnips 80-90 days before your area's average first hard frost so bulbs have time to size up. For most of the Midwest and mid-South, that lands between late July and early September. Planting later cuts bulb size and reduces the late-season tonnage deer rely on after frost.

When is the right time to plant oats for deer?

Oats go in 6-8 weeks before your first fall frost, which lands in September across most of the whitetail's range and slides into early October in the Deep South. Oats die at the first hard freeze in most areas, so pair them with winter wheat or rye if you want forage into winter.

What exactly counts as a food plot versus baiting?

A food plot is a standing planted crop managed as habitat, while baiting typically means placed grain, minerals, or feed on the ground. Many states, including Michigan, allow food plots while restricting baiting and feeding, but definitions vary, so check your state wildlife agency's current regulations before assuming either practice is legal.

Do deer actually like honey or sweet attractants?

Deer don't eat honey as forage in any practical sense. Honey-based products are scent lures and attractants, not planted food sources, and their use often falls under state baiting and feeding regulations, the same rules covering corn piles and mineral sites. Check your state's definition of bait before using them.

What are deer's favorite foods overall?

Preference shifts by season and region, but soybeans, clover, standing corn, and white oak acorns consistently rank near the top across whitetail range. Brassicas and turnips become highly preferred after the first frost converts starches to sugars, which is why those plots often get ignored early and hammered in late fall.

When is the best overall time to plant food plots for deer?

There's no single date; it depends on your USDA hardiness zone and species. Northern zones plant brassicas and clover in August through early September. Mid-latitude zones have through late September. Southern zones often wait until late September or October to avoid heat and drought stress on seedlings.

Can I plant clover and brassicas in the same September plot?

Yes, but stagger your thinking about them: brassicas need the longer runway (80-90 days before frost) so they should be prioritized for the earliest planting slot, while clover can go in a few weeks later within its own 45-60 day minimum window, often in a separate section of the same field.

Do I need to lime my soil before a September planting?

Ideally lime went down months earlier, since agricultural lime can take 3-6 months to fully adjust soil pH. If you're testing late, apply the recommended lime anyway; it keeps working into next season. Lean on oats or cereal rye for this year's planting since they tolerate a wider pH range than clover.
