DOMAIN SMACK DOWN SEED 1/2 ACRE Smack down offers two varieties of turnips that are easy to grow and fast to mature. Not only will this grow rapidly, but the dual-purpose mix produces a large purple spherical root and leafy forage that can both be grazed, providing high levels of protein and energy. This combination makes smack down one of the most popular food plots you can plant for whitetail deer. These two varieties of turnip were carefully selected to provide you both warm and cold season food options and offer attractive forages no matter the temperature or time of year.
