If you’re serious about attracting and holding deer on your hunting property, deer radish seed should be on your shortlist of essential food plot crops.
Known for its high protein content, exceptional palatability, and deep-rooted nutritional value, radish is a proven performer in both early and late seasons. This guide combines wildlife biology insights and practical hunting experience to help you select, plant, and manage deer radish seed for maximum results.
What Is Deer Radish Seed and Why It Works
Deer radish seed typically refers to forage radish varieties bred for wildlife food plots. Unlike garden radishes, these are cultivated to produce both lush green tops and large tubers rich in carbohydrates. Deer consume both parts, gaining vital nutrients that improve body condition, antler growth, and winter survival.
Key benefits:
- High nutrition: Often 20–25% crude protein in foliage.
- Frost sweetening: Cold weather converts starches to sugars, increasing attraction.
- Soil health: Deep taproots break up compaction and recycle nutrients.
- Long attraction window: Palatable from early fall through late winter.
The Science Behind Deer Attraction to Radish
Radishes are part of the brassica family, along with turnips and kale. They contain glucosinolates—compounds that produce a distinctive scent and taste deer find irresistible once plants mature. After the first frost, enzymes break down starch into sugars, giving the foliage and tubers a sweeter flavor that deer seek out in late fall.
Wildlife studies show that radish food plots can receive 30–40% more deer visits in December and January compared to generic cereal grains, especially in colder regions where natural browse is scarce.
Choosing the Right Deer Radish Seed
When shopping for deer radish seed, look for:
- Cold-tolerant varieties for northern climates.
- Quick germination (5–10 days) to outcompete weeds.
- Dual-purpose yield: large leafy canopy + substantial tubers.
- Blend compatibility: works well with oats, winter rye, and clover.
Popular forage radish varieties for deer include:
- Tillage radish (soil-breaking variety)
- Daikon-type forage radish
- Proprietary blends like Ravish Radish® or Trophy Radish™
Best Planting Times by Region
Timing is crucial for maximizing yield and palatability.
| Region | Planting Window | Notes |
|---|---|---|
| Northern U.S. / Southern Canada (Zones 3–5) | Late July – Mid August | Allows 45–60 days of growth before frost. |
| Midwestern States (Zones 5–6) | Early – Late August | Ideal for archery season attraction. |
| Southern States (Zones 7–8) | Late August – Mid September | Avoid heat stress by waiting for cooler nights. |
Pro tip: Plant too early, and the foliage may mature before peak hunting season. Plant too late, and growth will be stunted before frost.
Soil Preparation for Deer Radish Seed
Radishes thrive in well-drained soils with a pH between 6.0 and 7.0.
Step-by-Step Prep:
- Soil Test – Identify nutrient needs; radish prefers moderate nitrogen and higher potassium.
- Clear and Till – Remove weeds and loosen soil to at least 4 inches deep.
- Amend as Needed – Lime to adjust pH, add phosphorus and potassium per soil test.
- Firm the Seedbed – Radish seed is small and benefits from a smooth, firm planting surface.
Planting Guidelines
- Seeding rate: 5–8 lbs per acre when broadcasting; 3–5 lbs per acre when drilling.
- Depth: ¼–½ inch.
- Spacing: Keep even coverage; avoid clumping.
- Moisture: Plant before a light rain to improve germination.
Tip: If broadcasting, lightly drag or cultipack afterward to ensure good seed-to-soil contact.
Companion Planting for Extended Attraction
While pure radish plots are effective, mixing deer radish seed with other crops extends attractiveness:
- Oats for early season forage.
- Winter rye for late winter greenery.
- White clover for spring regrowth and perennial cover.
This staggered maturation keeps deer returning long after the radish foliage is consumed.
Growth Stages and Deer Usage
- Early Growth (0–30 days) – Deer graze leafy tops lightly.
- Mid-Growth (30–60 days) – Canopy thickens; tubers start forming.
- Post-Frost – Sugar levels peak; deer increase feeding intensity.
- Winter – Tubers exposed by deer digging; high-energy food source.
Managing for Maximum Yield
- Weed Control: Radish germinates quickly, but suppress weeds early with mowing or herbicide.
- Fertilization: Apply 40–60 lbs nitrogen per acre at planting for robust foliage.
- Overbrowsing Prevention: Fence young plots for the first 3–4 weeks in high-pressure areas.
