Have you been spotting holes in your cabbage leaves? The problem could be cabbage worms. Not only do they eat on cabbage, but they will also munch on other Cole crops, like broccoli, kale, cauliflower, kohlrabi, and more.
Cabbage worms are small worms that hatch out of eggs that are laid on the vegetables by white moths. When you see these white moths flying around your cabbage and other vegetables, you know it is time to spray or dust your plants to protect your harvest. Unfortunately, the only way to truly prevent the moths from laying eggs is to cover vegetables with netting or a grow tunnel in order to prevent moths from reaching the vegetables. When using a spray or dust, you will have to continually spray or apply the dust throughout the season to kill the worms. At Delaney's, we have grow tunnels and traditional and organic sprays.
And remember, always thoroughly wash your fruits and vegetables before eating them. This will help remove residues from chemicals and fertilizers.
