Brussel Sprout Plants - help!
First time on Forum and first time ever planted anything - so - planted some Brussel Sprout seeds a while back - they are now around 4 inches high in a cold frame and I hope to plant them out in a couple of weeks. In the last week the leaves have started turning yellow - not burnt from sun as we havent seen any sun in the recent downpour of drought. Dont appear to be overwatered - any ideas gratefully received! Thank you
