Sweat peas dying
I have grown several sweet pea varieties this year and they are all doing really well. Apart from one lot that have been sitting in a water trey with a constant supply of water. My question is, is it the constant wet soil that is killing the plants, they are about 4 inches tall and were doing great until recently. They have turned brown and shrivelled up
They are in the same soil and same conditions as the other sweet peas that are growing perfectly.
Any help would be much appreciated!
