Does 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 MoreWoodchuck damage - what does it look like?
Comments (5)Our resident woodchucks (we call them groundhogs here) happily consumed every petunia blossom in our garden one year! They seem to just like the petunia blossoms, not the foliage as much. We caught one in the act of breakfasting on the petunias, so I know it was not the resident bunnies. The petunias sort of regenerated afterward, but the plants were never quite the same after that. I find that the woodchucks/groundhogs generally won't eat snapdragons, so if you want a colorful flowering annual, I would try those instead. We have some lovely white snapdragons this year that I'm liking a lot, and the groundhogs haven't touched them. Snapdragons are one of the few non-natives we plant, but we plant them every year because of their reliable groundhog resistance. We don't grow Dahlia so don't know about groundhogs and those....See MoreDoes this look like slug damage? Can they climb this high?
Comments (6)Thank you for your response. I am so clueless about these things! That is why I'm asking, because I've never learned about these things. I was under the impression that a slug wouldn't climb six or seven inches off the ground, which is how high the holes are on the coneflower. I haven't checked at night yet, but I hollowed out a couple of spaces & put small bowls of beer near the plants with the most damage, into which I hope some slugs will fall! I'll keep you posted on my success. I'll look tonight with a flashlight. If I have a lot of mulch on the beds, could that make things worse? I had some help in the garden last year, and now that I am looking at the thickness of the mulch, it could be too much. From the reading I've done it sounds like they like to live in mulch. I was curious about what else it might be if not slugs, because if it isn't slugs, I know I'm going to be sad about my poor plants. I want to learn about what else I need to consider, like a beetle of some sort?...See MoreDoes this look like herbicide damage?
Comments (5)I wonder about the potting mix. Was it potting mix (suitable for containers?) I mistakenly bought a massive bag of organic Miracle Grow once, and when I was able to turn the bag over (after filling my containers), I noticed that it said (on the back of the bag) NOT for containers. Assuming that perhaps the reason was because of odours, I did nothing, and my plants didn't do well. Back to your problem. Does the mix contain Coir? I have read that sometimes that can be bad. In addition, we have to be careful or aged manure these days because some farmers feed their cattle hay that has been treated with herbicides. It goes right through the cattle, but persists in the manure, and tomatoes are very sensitive to such things. I wish you good luck. Linda...See More- 13 years ago
