My beautiful tomato plants have turned brown and are rapidly dying.
This has occurred in the last 48hrs.
Is it due to some kind of fungal blight?
Prior to this they were thriving and full of fruit. I was given two plants by a friend (surplus) and stuck them in the flower bed as I has no other space left. They've been fed with miracle-gro'd at fortnightly intervals as per instructions and were tolerating the feed happily.
Any advice appreciated
