TL;DR
Cereal grains (oats, wheat, rye) and brassicas like turnips and radishes handle acidic soil (pH 5.0 to 5.5) far better than clover or alfalfa, which need pH 6.0 to 6.5. If you can't lime before planting, choose grains or brassicas this season and lime for next year's legumes.
What's the best food plot seed for low pH soil?
| Cereal rye | 5.0 | 5.5 to 7.0 | |
|---|---|---|---|
| Oats | 5.0 to 5.5 | 6.0 to 7.0 | |
| Winter wheat | 5.5 | 6.0 to 7.0 | |
| Brassicas (turnip, radish, kale) | 5.3 to 5.5 | 6.0 to 6.8 | |
| Red/white clover | 6.0 | 6.0 to 6.5 | |
| Alfalfa | 6.5 | 6.5 to 7.5 | Those ranges come from soil fertility guides published by university agronomy programs, not seed marketing copy, so treat them as a planning tool, not a guarantee [1] [2]. If you want a plan built around your actual soil test numbers rather than a generic pH chart, that's exactly what a food plot seed plan should account for. |
If your soil test came back at pH 5.5 or lower and you don't have time or budget to lime before planting, go with cereal grains or brassicas instead of clover or alfalfa. Oats, winter wheat, and cereal rye all tolerate acidic soil reasonably well, and brassicas like turnips, radishes, and kale aren't far behind. Clover and alfalfa are the pickiest crops in the food plot world for pH, and they'll struggle or fail outright below 6.0. This isn't a workaround forever. Lime takes months to change soil pH, sometimes a full growing season or more depending on how much you need and how it's incorporated. So the real strategy is: plant something pH-tolerant this year, get lime down now, and plan for clover or alfalfa once your soil test shows you're in range. Here's a rough tolerance comparison based on land-grant extension guidance for common food plot species: | Species | Minimum workable pH | Ideal pH range |
Why does soil pH matter so much for food plots?
Soil pH controls how available nutrients are to plants, more than whether the plant can survive. Below pH 6.0, phosphorus starts binding to soil particles and becomes less available even if your fertilizer numbers look good on paper [3]. That means you can spread all the fertilizer you want and still get a thin, yellow plot, because the plant physically can't pull up what it needs. Legumes take the biggest hit. Clover, alfalfa, and soybeans depend on rhizobia bacteria in the soil to fix nitrogen from the air, and those bacteria slow way down or die off in acidic conditions [4]. That's why a clover plot in low pH soil often looks stunted and pale by midsummer even with decent rainfall. It's not a watering problem or a deer pressure problem. It's a chemistry problem. Grasses and brassicas are more forgiving because they pull nitrogen straight from the soil or fertilizer rather than fixing it biologically. That's the core reason they show up on every low pH recommendation list.
Do deer eat sorghum?
Yes, deer eat sorghum, particularly the grain heads in late summer and fall, but it's more commonly planted as a screening or standing cover crop than a primary food source. Whitetails will browse young sorghum shoots and clean up dropped grain, but it's not their first choice compared to soybeans, clover, or acorns. Sorghum has one real advantage for low pH ground: it tolerates acidic soil about as well as corn, meaning down to roughly pH 5.5 without much yield penalty [2]. If you've got a tough, thin-soil field and want height for screening plus some incidental deer food, grain sorghum or a sorghum-sudangrass blend is a reasonable low-input option. Just don't expect it to pull deer the way a soybean field or brassica mix will.
Do deer like clover, and does it work in acidic soil?
Deer like clover a lot. It's one of the most consistently preferred food plot forages across whitetail range, offering high protein (often 20 to 25 percent crude protein in good stands) through spring, summer, and fall [5]. The problem isn't preference, it's performance. Clover planted in soil below pH 6.0 will germinate, but the stand thins out fast because the rhizobia bacteria that fix nitrogen for the plant can't function well in acidic conditions. If your soil test says pH 5.5 and you plant clover anyway without liming, you'll likely see a decent first few weeks followed by weak, yellowing plants by the second month. Most extension agronomists recommend getting soil to at least pH 6.0, ideally 6.5, before investing in a perennial clover stand [1]. Given that a good clover plot is supposed to last three to five years, it's worth waiting one season and liming properly rather than planting into bad chemistry and redoing it next year anyway. For a broader look at how clover stacks up against other perennial options, deer food plots covers species selection in more depth.
Do deer like honey (honeysuckle) as a food source?
If you mean honeysuckle, yes, deer browse it heavily, and Japanese honeysuckle (Lonicera japonica) is actually considered a preferred winter browse in the southeastern U.S. because it stays green later into cold weather than most native forage [6]. It's not something hunters plant as a food plot crop though, since it's an invasive species in much of the eastern U.S. and many states restrict or discourage planting it. Deer don't eat honey itself in any meaningful nutritional sense; that's a common mix-up between the word 'honey' and 'honeysuckle.' If you're looking for a woody browse or edge planting that deer favor, honeysuckle isn't a fair comparison to a managed food plot. Check with your state extension office or wildlife agency before planting anything classified as invasive on your property.
When should you plant food plots for deer?
Timing depends on whether you're planting a spring/summer plot or a fall plot, and both depend heavily on your USDA plant hardiness zone and local frost dates. As a general framework used by most extension programs: warm-season plots (soybeans, cowpeas, sorghum) go in after your last frost date, typically April through June depending on latitude, while cool-season plots (brassicas, cereal grains, clover) go in 60 to 90 days before your first fall frost. The fall planting window is the one most hunters care about most, since it lines up with hunting season. In the northern tier (zones 3 to 5), that often means late July through August. In the mid-South (zones 6 to 7), September is typical. In the Deep South (zone 8 and warmer), you can often wait until late September or October. Soil pH timing matters here too. If you're liming, get it down as early as possible, ideally months before planting, since lime needs time and soil moisture to react and move pH upward. Planting into freshly limed but still-acidic soil doesn't give you much of a head start over not liming at all.
When to plant oats for deer?
Oats are a fall cool-season planting in most of the whitetail range, generally going in the ground 6 to 10 weeks before your area's average first frost date. That timing gives the oats enough growing season to establish a few inches of leafy growth before cold weather slows them down, which is when deer start hitting them hard. Oats are also one of the better low pH options on this list, tolerating soil down to around pH 5.0 to 5.5 without major yield loss [1]. That makes them a smart fallback if your soil test came back low and you don't have time to lime before your planting window closes. They winterkill in most northern climates, so don't expect them to survive as a perennial; treat them as an annual, replanted each fall.
When to plant turnips for deer?
Turnips go in the ground in late summer, generally 80 to 90 days before your first expected fall frost, since they need that window to bulb out and build sugar content before deer start really hammering them. In most of the whitetail range that means a July to early August planting date, though the Deep South can push into September. Turnips are a solid low pH choice, workable down to roughly pH 5.3 to 5.5, though yields improve noticeably once you're above pH 6.0 [2]. One quirk worth knowing: deer often ignore turnip bulbs and foliage early in fall and don't switch on to them until after the first hard frost, when cold weather converts starches to sugars and makes the plant taste sweeter. If you're not seeing pressure on your turnip plot in October, that's often normal, not a failure.
What is a food plot, exactly?
A food plot is a planted area, usually somewhere between a quarter acre and several acres, established specifically to provide supplemental forage for deer and other wildlife. Unlike a farm field, the goal isn't yield for sale, it's attraction, nutrition, and holding power on a property during hunting season and beyond. Food plots generally fall into two categories: annual plots (replanted each year, like brassicas or cereal grains) and perennial plots (clover or alfalfa, lasting three to five years before needing renovation). Most experienced managers run both types across a property, since annuals tend to pull deer hard in fall and perennials provide steady spring and summer nutrition when deer need protein for antler growth and lactation. For a rundown of common food plot species and how they're typically laid out on a property, food plot whitetail is a good next read.
What are deer's favorite foods overall?
There's no single universal answer, since preference shifts by region, season, and what's naturally available, but extension research and deer forage studies consistently rank acorns, soybeans, and clover near the top across most of the whitetail range. In fall, acorns (especially white oak acorns, which are lower in tannins than red oak) are often preferred over almost any planted crop when they're dropping heavily. Among planted crops, soybeans are frequently the top choice in summer for both protein and volume, clover is a consistent spring-through-fall favorite, and brassicas or cereal grains tend to take over as the preferred food source once cold weather hits and other options die back or lose palatability. Deer are also opportunistic; a plot that gets ignored in September can become the most hammered spot on the property by December once a frost sweetens it up or acorns run out.
How do you fix low pH soil for a future food plot?
The only real fix for low pH soil is agricultural lime, and the amount you need depends entirely on your soil test results, not a generic per-acre number. A soil test will report both your current pH and a lime recommendation in tons per acre, and that number varies a lot based on your soil's buffer capacity (heavier clay soils typically need more lime to move the same amount than sandy soils) [3]. Lime works slowly. Most extension programs recommend applying it 6 to 12 months before you need the pH change, and note that it needs to be incorporated into the top 4 to 6 inches of soil (tilled in, more than surface spread) to work efficiently. If you're on a compressed timeline, pelletized lime reacts a bit faster than ag lime but usually costs more per ton of neutralizing capacity. This is also where your soil test lab's recommendation matters more than any general chart, including this one. Your lab knows your buffer pH, texture, and current nutrient levels; use their lime and fertilizer numbers as the final word for your specific field. If you want help translating a soil test into an actual seed and fertilizer plan, that's the specific gap PlotSeason's $99 Custom Food Plot Plan is built to fill; it's general planning guidance based on your inputs, not a substitute for site-specific agronomy advice from your soil lab or local extension office.
What should you plant this year if you can't lime in time?
If your soil test just came back low and your planting window is close, don't force a legume-heavy perennial mix into ground it isn't ready for. Go with a cereal grain and brassica blend instead. A mix of winter wheat or cereal rye with turnips and radishes will tolerate pH down to the 5.3 to 5.5 range, give you fast fall growth, and still pull deer hard once frost hits [1] [2]. Put your lime down now regardless of what you plant this season. Even if it doesn't fully correct pH before this year's crop goes in, you're banking progress toward next year, when you can transition part of that field to clover or alfalfa once the soil test confirms you're in range. One more practical note: check your state wildlife agency's rules before adding any supplemental feed, mineral, or attractant products near your plot, since baiting and feeding regulations vary significantly by state and some states classify certain food plot practices differently from baiting. A planted, standing food plot is legal nearly everywhere deer hunting is legal, but piled feed, mineral licks, and some attractant products are regulated separately in many states.
Frequently asked questions
Do deer eat sorghum?
Yes. Deer browse young sorghum shoots and eat the grain heads, especially in late summer and fall. It's more often planted as a screening crop or drought-tolerant filler than a primary attractant, but it does tolerate low pH soil (down to about 5.5) about as well as corn.
Do deer like clover?
Deer strongly prefer clover, and it's one of the highest-protein food plot forages available, often 20 to 25 percent crude protein. The catch is that clover needs soil pH of 6.0 or higher to thrive, since the nitrogen-fixing bacteria it depends on struggle in acidic soil.
When to plant oats for deer?
Plant oats 6 to 10 weeks before your area's first fall frost, which is typically August in northern zones and September in the mid-South. Oats tolerate soil down to roughly pH 5.0 to 5.5 and winterkill in most climates, so treat them as an annual.
When to plant food plots for deer?
Warm-season plots (soybeans, sorghum) go in after your last spring frost, usually April through June. Cool-season plots (brassicas, cereal grains, clover) go in 60 to 90 days before your first fall frost, which ranges from late July in the north to October in the Deep South.
When to plant turnips for deer?
Plant turnips 80 to 90 days before your area's first fall frost, generally late July through early August in most of the whitetail range. Deer often don't hit them hard until after the first frost, which sweetens the bulbs and foliage by converting starches to sugar.
What is a food plot?
A food plot is a planted area, usually a quarter acre to several acres, established to provide supplemental deer forage rather than a crop for sale. Plots are either annual (replanted yearly, like brassicas or grains) or perennial (clover, alfalfa, lasting three to five years).
What are deer's favorite foods?
Acorns, especially white oak acorns, are often the top preference when available. Among planted crops, soybeans lead in summer, clover is a consistent favorite spring through fall, and brassicas or cereal grains take over once cold weather hits and sweetens them.
Do deer like honey?
Deer don't eat honey in any nutritional sense; that question usually means honeysuckle. Deer do browse Japanese honeysuckle heavily, especially in winter, but it's invasive in much of the eastern U.S. and isn't planted as a managed food plot crop.
What's the best food plot seed for pH below 5.5?
Cereal rye is the most tolerant common option, handling soil pH as low as 5.0. Oats and brassicas like turnips and radishes work down to about pH 5.3 to 5.5. Avoid clover, alfalfa, and most legumes until you've limed closer to pH 6.0.
Can you plant clover without liming first?
You can, but it usually performs poorly. Clover will germinate in acidic soil, but the rhizobia bacteria it needs to fix nitrogen slow down or die off below pH 6.0, leading to thin, pale stands within a few months. Most extension agronomists recommend liming to at least pH 6.0 before planting clover.
How long does lime take to raise soil pH?
Lime typically needs 6 to 12 months to fully react and raise soil pH, depending on the amount applied, soil texture, and how well it's incorporated into the top 4 to 6 inches of soil. Pelletized lime reacts somewhat faster than ag lime but costs more per ton of neutralizing capacity.
Do brassicas need lime like clover does?
Brassicas are more pH-tolerant than clover, growing acceptably down to pH 5.3 to 5.5, but they still yield better above pH 6.0. Liming isn't as urgent for brassicas as it is for legumes, but it still improves nutrient availability and overall plot performance.
