This is the first year I have gone totally organic for my yard and garden. My red potato leaves on just 3 plants are turning yellow, the other plants are doing fine, it doesn't look like anything is eating on them. I have been useing compost tea soil drench and garrett juice every two weeks(Seems to really give them a perk). I have also mulched the potatoes with Alfalfa hay on 2/3 of my potato plants per Howard's suggestion. The yellowing is happening on a plant that is not mulched and one that is, so I don't think thats the problem either. I plant potatoes every year and don't ever remember this happening. (BTW-I rotate crops every year). Does anybody know what might be happening to them? I just don't want this to spread. Thanks.
