why are they turning yellow and what can I do to prevent it? they are red potatoes, planted in mid May, hilled up around the plants and looked beautiful before the leaves turned yellow.
Thanks in advance
Do you have any idea how long that variety is supposed to take until harvest? I read that you can get some that mature in as few as 65 days, so maybe it's time to dig the tators? When the vines die due to natural causes, they should be ready.
