The Edible Gardens of Glendower is talking about growing Celery from Wellington

Garden ready!

I have left my giant celery to flower – hoping for more self-seeding celery next year. Several weeks ago, the plant was covered in tiny white/grey bugs. Now it has a ladybug or two on each stem, who have obviously been feeding on the previous population. I have also left my kale plants in, hoping for seed – and they are covered in cabbage aphids. I wonder if the ladybugs will move over to the kale next?
