Our Trophy Radish is made of Jackhammer Radish, a fast growing daikon radish variety which can be a great addition to deer hunting food plots. 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 can continue to provide a food source for deer for several months, as the tubers remain palatable throughout the winter. Plants 1/4 acre.
