For Brassica In the Northeast - Spray round up in June -
Then inMid July when all the grasses are DEAD -
Disk & Prep soil with a firm seed bed -
Lime & Fertilize as required (brassicas like lots of Nitrogen and a PH above 5.5 with 6.5 being excellent)
Then Broadcast 4-8 lbs of Brassica Mix as per the bag instructions ( canola/rapseed usually - but also turnips, Kale and other similar type plants are in most mixes). ROLL the seeds in ( do not disk them in).
Synopsis - June - March:
I plant them most years - but I've never been really happy with the way the deer use them DURING deer season. They always eat the Soybeans first during hunting season - and by January/February start to key in on the brassica. I'd suspect that if all you offered was brassica - and your neighbors didn't leave a lot of other crops out - it would be a different story...................................they are easy to plant!
