Cucumber foliage problem - PICS
Comments (4)It looks suspiciously like virus. Are all the leaves on that vine affected? If so, I'd take the precaution of removing that plant. Some viruses can be spread from plant to plant via insects, some also by abrasion -- leaves rubbing against each other....See MoreCan anyone identify this foliage problem? (Pics)
Comments (10)In this first shot 3 visable plants have sunburn. The datura got hit on 3 leaves right down the front. There is some colorado potato tick damage on the lower leaves if you look close enough - tiny spots right through. The leaf hanging on the datura is from a brug to the left thats not in the picture. The back 2 PPxAmber brugs each got burned on 1 spot although you would need to zoom in to see the leaf on the back one, one of the newer ones pointing our way, although the burn took the tip off. Nothing spread. This picture is from at least a couple of weeks ago. The datura in question is on the far left of this shot, it only shows its heighth so Ill get some shots of these same plants tomorrow to prove it does not spread. Wont I look silly if it did...lol This is a brutal shot, parental guidance is necessary. The earwigs second generation came while I wasnt looking. This brug was really attacked in a matter of 2-3 days, though I did see some smaller damage before - should of heeded the warning signs and got out the poison. Its also in one of the high sun to late day locations at the side of the house. And is showing multiple stages of the burn. The whimpy green area is just before the slight yellowing you can see on the left leaf. This plant got it all over!Its one of 2 Jinny Linds of which its leaves are my favorite. This does not usually happen but this summer has been nasty. I pride myself on perfect leaves despite that even branches from other plants or finger nail holes grow with the leaves. My neem oil mix, usually sprayed underneath the leaves, usually keeps most pests away (colorado beetles and colorado potato ticks this year) but earwigs require their own poison. This is the other Jinny Lind and Super Pink. More in an on-off shaded area. Sandy...See MoreDahlia foliage problem: whitefly, mites, underwatering or virus?
Comments (5)I agree with Mandolls concerning the lower branches... they tend to deteriorate, and become bug food if you don't snip it off when they are on the way out. That helps airflow, avoiding leaf mold and makes it harder for bugs to 'climb aboard.' With that said, it is possible there is something else going on in your dahlia bed, but its hard to tell without seeing the plants and what percentage of each plant is effected at any given time. I, too, would defer that kind of diagnosis to a long time grower. It is certainly likely that you're under watering, especially if you're getting lots of sun. If the plant isn't hydrated well, it is more likely to be effected by virus and other ailments. Personally, I'd soak the soil all the way around the plant at least each week with a hose if you don't get a soaking rain, to ensure even moisture and tuber growth. i have single soakers down each double row, but have occasionally seen dehydration signs in the leaves, so I've been supplementing when needed. I really need to rework my watering system next year, as I don't want to invest more right now. Through the grapevine, I heard that a long-time grower runs four slow drip lines per double row to ensure enough water, and in the peak summer temps of 95 degrees, supplies two gallons of water per plant per day by running his system 24 hours a day....See MorePotato Foliage Problem
Comments (6)Jan, I understand about the swift transition from 'too cold' to 'too hot' as it commonly happens here as well. I often skip most cool-season crops completely because about the time they are almost ready to produce something, our high temps zoom up into the 90s and I get zero harvest from them. This year, I was feeling cocky because in last year's cool/wet spring/early summer, all my cool season crops produced the best crops they ever have, so I planted tons of cool-season crops this year. I know that by doing that, I probably jinxed my own garden. So, this week we've been as cold as 39 degrees here, and as hot as 86 degrees, and I've been watching the broccoli and Sugar Snap Peas very carefully. So far, all is well, but at a garden a couple of miles from us, their broccoli is bolting and flowering and that is making me nervous. I cannot think of anything in cow manure that would hurt your potato plants, especially since you are so experienced at using manure properly. I am assuming your cows don't eat any forage crops that have been sprayed with a clopyralid or aminopyralid product. Jleroi, You're welcome. I'm the queen of links, with at least one link in my 'memory bank' for every occasion. As hard as it is to find something reliable online that you can trust, I try to remember and share the ones that apply to a given situation.
