Container Zucchini going down :(
Comments (5)Thank you, both. Nitrogen shortage could be a potential, as the leaves are not as deep, dark green as they once were. I fertilized a few days ago at about half strength. I may give them another half strength shot and see what happens. The problem with the yellowing is that it's not just the old growth. The new growth is developing the yellow patches as well, it just started with the bottom leaves and worked its way up. I don't think it's a watering issue, though if it were it would be under watering, as we've had some high heat and the plant has become a bit droopy a few times, but the marked change in color, the yellow patches, smaller leaf size, and stagnant zucchini growth tells me that something is going on with this plant, considering it was growing insanely fast and producing faster than I could come up with things to do with the zucchinis! I'm going to fertilize again today and see what happens. Thanks!...See MoreDoes this look like SVB damage? (pics!)
Comments (10)RTG No, it doesn't look like SVB damage to me. I think it's a watering issue, though I don't know which issue it is! Maybe more information would help. At first I thought it might be overwatering, since that causes leaves to turn yellow. That's a possibility. You'll know how often you've been watering them, and they probably need a lot of water in the heat. But I notice you're in zone 9, so I suspect it's that small black container that's causing the trouble if you have it sitting in the hot sunlight all day. A dark container can literally cook the roots and destroy the plant. But I don't think yours is at that stage yet since the upper leaves still look healthy. I'm also growing squash plants (two of them) in five-gallon white containers with a large drainage hole, containers probably larger than yours (though it's sometimes hard to tell from a photo). I'm finding that they need water three times a day in this 90-degree heat, far too often for me to remember to do regularly. If I wait too long, the plants wilt and then the leaves sunburn, turn crisp, and die. (I don't think I'll grow them or any more cucumbers in a non self-watering container again because of their water needs.) They're producing plenty of blossoms and squash but they look a little naked with so many missing leaves! So, if that's the problem, what to do? First, I'd remove the yellowed leaves to prevent disease from vectoring there. And if it could possibly be done with very little disturbance, I'd transplant it into a much larger container that's light-colored to prevent the roots from becoming baked or root-bound and unable to take up water and nutrients. Keep them in the shade while they get used to their new home and start growing again. Don't fertilize them until they're growing again. If that isn't possible, all you can do is shade the container so it doesn't absorb the sun's heat and keep them well-watered. But if the container is as small as it appears to be, you'll need to water them several times a day, and even then you'll have to pray that they make it. If it's a problem with overwatering, that's easy to fix....See Moreis it possible that pesticide spraying damaged foliage?
Comments (4)Brother Cadfael's growth looks like rosette disease. If there is any recurrence, you should remove the plant immediately and bag it. I never heard of insecticide causing growth like that, and I think you can dismiss that possibility. Sumithrin is rated as having low toxicity to birds and mammals. It is highly toxic to aquatic life. Here is a link that might be useful: sumithrin...See MorePleiospilos nelii with Red Spider Mite Damage - Keep or Toss?
Comments (10)Personally I kind of thought the reason most sites say to discard the plant is their way of trying to contain/control the spread. Totally just my thoughts on it, but it makes sense to me if a person isn't going to stay on top of or treat the plant as necessary then the pest, will spread or worse if not treated properly like most pest become a super mutation that is not controlled through current methods. Anyway I probably shouldn't share my theories until I have facts, and all I know is animals. One more opinion these guys are not necessarily deemed beautiful by the average person, it is a beauty is in the eye of the beholder kinda plant! Only its owner could love it! Now that I have one I feel safe saying that ;) lol! I know you love your mesembs and I am guessing you don't truly want to dump him! I agree with the others give him a gangster name and enjoy please don't ever think that I am feeling knowledgeable I just enjoy conversations that don't involve Disney or toys ;) I crave conversations with others unrelated to Mickey or Frozen! Hope to see "Capone or Scarface" around a few months from now. Also hope my humor translates. Blessings...See MoreElfRosaPNW8b
