Dying Sweet potatoes
Comments (9)Larry, I have a couple of thoughts on the yellowing leaves, but I don't know that I have any solutions to recommend. Like Carol, I think it might be heat stress or drought stress. However, if you had several inches of rain in a fairly brief period recently, then it likely is something else--possibly fungal disease or maybe something bacterial, unless..... Unless you planted them in a nematode infested area. In that case it might be nematode damage. Another thing I can think of that might cause the yellowing foliage would be fusarium wilt, but if that is what it is you'll know pretty quickly. Usually it hits the plants one day and all you notice is yellowing leaves, and then within another day or two you see the yellowing leaves followed by wilting and plant death. There is not a cure once fusarium hits. Generally I do not see diseases on sweet potatoes except following a period of very heavy rainfall, and then I'll see one of the rot diseases that causes the stems and/or leaves to turn black and rot. If the plants looked bad when you planted them, then the best thing to do at that time would have been to dip them in a fungicide recommended for sweet potatoes. Sometimes that can prevent further fungal issues from developing. Sorry, I feel like I'm not being very helpful. What I likely would do would be to gently dig in the soil near the most yellowed, most wilted plant and see if the soil is either excessively wet or excessively dry. I'd try to push back the soil from the crown of the plant where the foliage emergences from the ground and check for any sign of disease on the stems. If Daconil still is labeled for use on sweet potatoes, you could try spraying the foliage of your plants, or you can use copper as long as the label doesn't warn against using it in excessively high temperatures. If the problem is a fugal disease, that likely would keep it from spreading from one plant to another. Sweet potatoes are prone to many diseases that cause leaf spotting and yellowing but I think they must be more common in humid areas because I just don't see them here in my area where it usually is hot and dry with relatively low humidity during sweet potato season. George may have some ideas for you since his climate and weather in general are more like yours than mine are. Finally, if you see this disease hit and then move up a row of plants, one after another, in a straight line, that would seem like it might be cotton root rot, which I had trouble with in Texas, and for the first couple of years here. Cotton root rot's name can be misleading because you don't have to have grown cotton in a specific area in order for your plants to get it. It is soil-borne and affects several thousand different plants. I think there's only a really slim, almost miniscule, chance it would be CRR though. Dawn...See MoreUh oh, I think I shoulda pruned
Comments (1)Sacrifice many of the "just leaf" branches to increase air circ and leave the suckers going. Those that are "falling toward the ground" can just droop. They may bend but they don't break. But you have learned a valuable lesson - 2 plants don't share anything...much less a cage. ;) Dave...See Morecat peeing not spraying!!!!!!!!!!!
Comments (9)I just want to get this straight because I'm all confused now. The way I understand his urine issues is that he pees in the litter box sometimes, but not all the time. When he is peeing outside of the box, he squats just like normal. So my questions are: Is the "sandbox" the same thing as a litterbox and is it outside or inside? How long has he been urinating outside the litterbox? When was he checked out for a urinary problem? What were the results of the urinalysis? What other tests were done to rule out physical problems in relation to urinating? Just because he is not spraying doesn't mean that it isn't a testosterone-related problem. Different cats mark territory in different ways. Some spray, some pee, some poop, some just rub themselves all over everything within reach. The only problem is that even if this is a testosterone-related issue, the behavior may be already ingrained and may not correct itself even after he is neutered becaue he's been doing it so long. If that's the case, you'll need to start a behavior modification program to get him to stop doing this. But you won't know what's going to happen until about 6 weeks after he's neutered. About the crying: Cats are basically nocturnal animals, so he may be crying at night because he's just not adapted to a dinural schedule. Certain breeds of cats just make a lot of noise, so if he is mixed with Siamese or some other loudmouth, they may just be his personality. There could also be a stray/outdoor cat or other animal coming near the house that he sees or hears and he's talking to it. I don't know if he can see/hear outdoors or not, but if so that is a possibility. If he doesn't seem painful or in distress, then at least he's comfortable. Although I understand that would be really annoying to listen to....See MoreNeed help identifying what disease is on my Inula helenium
