Yeah I am aware of the blast of water solution but as simple as that sounds it is not easy getting all parts of the plants. As I mentioned above my main concern is that I don't want the aphids getting on the broccoli heads, so I've been blasting the broccoli heads with water. I still blast the plant with water but know that there will be missed spots. I inspect the plants and look for the telltale sign of curled up leaves and then crush that part of the plant.
I have not seen lady bugs but I have seen some small waspy looking things, so maybe they've been helping me out.
Good idea about changing up the type of kale.
I am also hoping that I can get my timing right so that I can get a late fall / early winter crop of broccoli and Brussels Sprouts. The broccoli and Brussels Sprouts I am growing now are basically over-wintered plants.
