My strategy has worked. I have tried growing broccoli several times now, and never been successful. The plants I have now are the most advanced version of cabbage, broccoli and cauliflower I have ever managed, and by golly I'd like to keep them going! We picked several cabbage worms off the broccoli and cabbages this week, so I began a daily inspection. I started putting the worms in a little bowl on the side of the garden bed to entice the birds to do their part. I just caught a cardinal and his mate having a fabulous mother's day buffet in the brassicas!
