Overview

Brassicas — including turnips, radishes, and rape — are the kings of late-season deer attraction. These cool-season annuals produce massive tonnage per acre (some varieties yield 8-10 tons) and have a unique property: the first hard frost converts starches in the leaves and bulbs to sugars, making them suddenly irresistible to deer. Before frost, deer may ignore your brassica plot entirely. After frost, you'll see it get hammered overnight. Forage radishes like Daikon and tillage radishes also break up compacted soil with their large taproots, improving the ground for whatever you plant next. Purple Top turnips and Barkant turnips are proven food plot varieties.

Why Deer Love Brassicas (turnips/radishes)

Before frost, brassica leaves provide 15-20% crude protein but deer largely ignore them due to bitter glucosinolates. After a hard frost (below 28°F), those compounds convert to sugars and the plants become some of the most attractive food sources in the woods. Deer will dig turnip bulbs out of frozen ground in January when nothing else is available. This late-season attraction coincides perfectly with late rifle and muzzleloader seasons.

Soil & Growing Conditions

Best Soil Types

Well-drained, fertile soil produces the biggest bulbs and highest tonnage. Loam and clay-loam are ideal. Avoid waterlogged sites — brassica roots will rot in standing water.

Soil pH Range

6.0–7.0 (ideal 6.5). Brassicas respond dramatically to proper pH — a limed plot will outproduce an unlimed one by 3-4x.

Planting Depth

¼ to ½ inch. Brassica seed is small but germinates aggressively in cool, moist conditions.

Planting Tips

  1. 1

    Plant 60-90 days before the first expected frost. Timing is critical — too early and plants bolt, too late and they don't size up.

  2. 2

    Brassicas are heavy feeders. Apply 300 lbs/acre of 13-13-13 and consider supplemental nitrogen (50 lbs urea/acre) at planting.

  3. 3

    Mix turnips and radishes together for diversity — radishes mature faster and deer eat those first, then switch to turnips.

  4. 4

    Brassicas are an excellent choice for new food plots because they tolerate less-than-perfect seedbeds.

  5. 5

    Pair with winter wheat or oats to give deer something to eat before the frost triggers brassica palatability.

Common Mistakes to Avoid

Planting too early in hot weather — brassicas bolt (go to flower) in heat and produce no usable forage or bulbs.

Expecting deer to eat them before frost — this is normal. Don't tear up a 'failed' brassica plot in October. Wait for frost.

Planting too thick — 5 lbs/acre is the rate. Going heavier produces more leaves but smaller, less attractive bulbs.

Not rotating — brassicas in the same plot year after year leads to disease buildup. Rotate with clover or cereal grains.
