Any ideas?

On a good note, the comfry plants (have three huge ones) are doing very well. I pull the large leaves off and put them in a barrel with water. I then cover with an old towel. The results? The best fertilizer ever, even though it smells like something has crawled into the barrel and died there. The neighbours were unimpressed when I used it to water the veg... and going back into the greenhouses on a hot day is enough to make your eyes water.
