No food plot is going to be good all years. That’s why u must have multiple plots: grains, legumes, brassicas, cereal grains, etc. all the stuff in dbltree section.
Case in point.... last year.... I had fields of beans. It was “warmer” winter. I mowed those beans this spring & had volunteer beans everywhere. They hardly got eaten and were crummy to hunt on. Will I still plant beans? YEP- cause not all winters will be warm (sure wish we had snow right now!).
I’ve actually never had a “total” brassica failure.... a way to avoid that is start about July 25 if you have a lot to do.... reseed if needed weeks down road. I plant about 1/2 of mine on lower bottom ground or super high quality soil- almost bullet proof. Almost. If u have rotated rye mix in past- Organic matter will help u as well. If it’s a total bomb & 100% failure... put in rye/oats/peas, etc. in September.
So..... high fertility (lay on the fertilizer too & make sure PH is around 6.5-ish - add lime as needed) & seed a touch early if u have lots of plots. Add or inter seed as needed. IF u have ur soil right- it’s pretty amazing what September rains can “rescue” and make into amazing plots. Follow dbltree threads & rotations and it will work. BUFFET is the solution too..... do lots of things for plots if u are able.
