what nitrogen fixer to plant with brassica
If you were sneaky like me during winter you may have thought to sow lupin and mustard in tidy rows next to slow growing brassicas like cabbage, kale and broccoli. The nitrogen fixing takes place while your brassica crops are growing which helps to grow decent heads rather than all leaves. A green manure crop is a perfect companion mix for those veggies; especially if you donât have the space to put your whole garden to bed over the colder months.
