After the householder had sown the wheat in the field, his servant came to report that tares were growing among the grain.
Start to dig in overwintered green manures such as grazing rye and winter tares.
The farmers sow some tares for seed, instead of pease; never for hay or soiling.
Where there is the true, you will always find the counterfeit and where there is wheat you will find the tares.
I found they favor many black baits, and will take tares in the early season, mirroring part of their natural diet.
