We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
Could someone tell me what is wrong with my zucchini leaves, and what I should do to fix them? Or is it a problem that needs to be fixed? I have had a problem keeping them watered enough with drought conditions and extreme water restrictions. I do try to water by hand 1 or x a day from my rain barrel. I don't see insects. They are in the ground. I started the plants in peat pots the first week of March, and I removed the pots and put them in the ground about 3 weeks ago in mounds.
Expanded view. There may be more than zucchini plants in the mound. I have been mixing all my mound plants (zucchini, birdhouse gourd, water melon, cucumber), and have put a tomato cage around them, to give them some climbing space. I have two mounds right now, and I am putting in a third.
starsplitter - if you have fuzzy white stuff on your leaves, it's probably Powdery Mildew, which can be fatal if not treated. The very best product to kill it in it's tracks is "Fung-Away" from this company.
Don't use products containing oil when it is very hot - the oil will burn the leaves. I have just sprayed my roses with Pyola for aphids because it's still cool here, but I wouldn't do so in the summer.
june-nmexico - I used to raise African violets, and used "Fung Away" on them. If you've ever tried growing AV's you KNOW how hard they are to keep alive! "Fung Away" saved many an AV from certain doom, so I'm sure it would do wonders for your Phlox.
My zucchini and scallops have always had white along the veins, some more than others. For me, as long as it doesn't rub off, or look different in texture from the rest of the leaf, I don't worry about it :)
Thanks so much. I just needed a bit of assurance. I had no idea. I thought the plants looked good and I couldn't figure out why the leaves were blanching. I will double check and check throughout the season for mold/mildew.
Your zucchinni is going to die. Most likely. I've had the same thing on mine last year and this year. It also hit the yellow squash. I do think it's some sort of powdery funk. But then again I'm no expert. Ok, this is how it's broken down for me:
Acorn Squash: it blights it, but last year still managed to get a few good ones, this year, looks like we'll have one decent acorn squash.
Butternut Squash: Planted further away from the infected ones, so far no sign of disease.
Pumpkin: total blight.
Zucchini: total blight...last year had one decent zuc this year looks like none.
Yellow c Neck: total blight
Cucumber: Not affected at all. Had a great harvest last year, didn't buy one from the store from June to September. This year they look okay.
Watermellon: no infection- was doing well until mice got to them
Cannaloupe: same as watermellon.
I have an organic spray that hasnt worked one bit.
It's active ingredients are potassium salts of fatty acids and sulfur. Don't buy it We bought it because it advertised as being safe to use up until the day of harvest but it hasn't done (sh**) for the bugs or powdery mildew.
I hope this has been of some help and someone else in the deep south can recomend what the heck to do to get rid of this stuff that destroys otherwise totally rockin plants.
neworleansdude - I lived in South Florida for over 30 years and learned very early on that growing anything in the Family: Cucurbitaceae Genus: Cucurbita was just this side of hopeless! Happily, I now live in NC and I've had a modicum of success - especially with cucumbers.
Okay, I don't have that problem, so maybe I will be okay. I am just trying to gather the facts, since I am new and learning about vegetable gardening. I am growing the zucchini for my catfish, and I would love a good crop to save me trips to the store and it needs to be pretty close to organic. Don't want to poison my catfish. I have cucumbers growing for me. I hope they are successful.
I have Japanese Eggplant almost ready to be picked. They are looking good.
I used to live in Fayetteville, NC, and we grew monster, delicious cucumbers. :)
starsplitter - I didn't know cucumbers could grow so large, until two summers ago! You're right, they are delicious. This year, I'm planting something called "Baby Cucumber Cucino" from Park Seed - described as "Two Bites of Heaven"
Starsplitter: I meant your zucs. I hope I'm wrong, but that photo you opened the thread with is how it looks at the start.
Honeybee: You've had this problem before and the "Fung-Away" actually works? I'm also curious about the cost and making sure it can be used on plants and the fruits are still safe for me and gf and friends to eat. I know most of what we all buy at grocery stores has more pesticide on it...I've tried doing the "organic" thing at home the last two spring/summers now and it's tough. Buying organic at whole foods or what not it just so darn expensive. Going out every other day to squish the pests by hand, not knowing what to do with fungus, mildew, blight, et.al.
At the same time we have so many great butterflies (which love our garden since they can lay their eggs on our plants), lizards, bees, wasps, preditor insects, rolly pollys, the occasional snake, racoon, or possum. And we live in the city, granted it's close to the river, but looks like we're going to move closer to the lake soon. And I love all the critters, so I want to find something I can spray to discourge them from eating certain plants, but not treat others so we get that great wild life.
Any suggestions? And thank you all for taking the time to read my ramblings.
Dude, if you have powdery mildew, like I show in my picture with the leafhopper, I've found that a spray of baking soda and water helps control it. Not sure what effect that has on the critters and their eggs, though.
I have a live and let live attitude with critters. I will treat for fungus, mildew, . . . but with critters I work on discouraging them. I am lucky in that my garden is new, so the pest insects really haven't found me. My biggest problem is a cat, squirrels, and a raccoon. I have found a great way to discourage mammals (doesn't work for birds or insects),., is to pour cayenne pepper on everything. Keeps my tender shoots, flower buds and fruits from being eaten. It also helps to keep the squirrels from digging in pots, and stones in a pot around a pot will also discourage squirrels.
I have a vegetable cleaner spray I use on store bought vegetables to remove pesticides, herbicides, . . .
I tend to subscribe to the "plant too much" philosophy. 1/3 for disease, 1/3 for the critters, and 1/3 for ME!!. I do use some neem oil and soapy water, but that's about it. I always have enough for all of us (knock on wood)...
Indy: baking soda and water? Just disolve it and spray and that can actually kill the powdery milldew? I'll try it! With the stuff I was using before it suggested using it after a rain or watering and once the sun was low. Sunset is around 7:30 here now, so is this something safe to use at 5pm or should I wait until the sun has gone down...also does it need to be able to sit of the plant for a day without rain or watering?
Thank you for your help. This year the powder has made it impossible to grow zukes or yellow and seriously, our one acorn squash plant that is hanging on has one fruit on it (but it still looks good, about average orange size now).
Looked at the photos again and ya know what: the problem with mine looks just like the photo Indy shared. Stars, I'm not sure what yours is, but it seems to be almost the same but maybe it needs more water so it stays closer to the main veins. I dunno.
Star: I know it's been less than a week but has your situation gotten better or worse?
It looks much the same. I am very careful about keeping it watered, because it is so dry here, and we are under severe water restrictions. I hand water all my plants from my rain barrel everday. If I miss a day, my plants wilt. We've had rain twice since February. We don't get regular rain until June. We have been in severe drought for 3 years.
I have a plant just purchased from a big blue box store that sells a national (or regional) nursery selection of plants. One of the Zucchini's I bought exhibits the exact same pattern on the leaf. This was fresh from the nursery on delivery day too.
I got the funny silvery shiny stuff on my squash leaves too and was freaking out. I was assured it was normal. I thought I had mosaic virus.
Apparently it is perfectly normal, my plants are large and growing and producing squash. I'm glad I didn't try to "cure" them of something and kill them. I think the wind is going to kill them for me though.
