Charles, For the second year my Broccoli crop has failed to deliver. I grew Parthenon this year, grew them on in 85cm pots and produced very healthy looking plants. Planted into my established Green Compost raised beds with a new dressing of 2″ and added Chicken manure pellets to the planting hole. Also sprayed with BT at planting time.
As you can see the plants are very poor and look to be affected by a rust of some sort?
