Anyone else have collards this massive? I started growing them from little seedlings from Lowes, in February last year. I expected them to bolt in the heat like certain lettuces I've grown, but they just keep getting taller and providing food for myself and the tortoises! Also, aphids are a constant battle which slow down growth on younger plants or even kill them. The smaller plant to the right of the two tall ones has been infested with aphids for a while, I always spray them down and seemingly get rid of all of them but they always come back and multiply exponentially.
