Our Trophy Radish is made of Jackhammer Radish, a fast growing daikon radish variety which can be planted alone or is a great addition to any of our deer hunting food plot blends. This plant species is known for its deep root system, which can help break up hard soil and improve soil health. Jackhammer radish has a relatively short maturity period, typically taking 60-90 days to reach full maturity. However, even after the plant has reached maturity, it continues to provide a food source for deer for several months, as the tubers remain palatable throughout the winter. Plants 1/4 acre.
