Is this powdery mildew on my squash?
Comments (2)It probably is. You are watering too often, I think. You shouldn't water at night. Water in the early morning so the leaves can dry off if you get them wet. Try not to get any water on the leaves. I would suggest you stick the soil with your fingers or something to measure if the soil needs water or not. Cut off any bad leaves and throw them in the trash, not the compost pile....See MoreYellow Squash and Powdery Mildew
Comments (18)I used Serenade and the Cornell formula this year on my zucchini and cucumbers and melons. Last year I fought SVB, PM, and some kind of bacterial thing. I did get a decent harvest, and my plants were troopers, but this year I am going to fight differently: 1) Row covers, row covers, row covers (for bugs which hurt the plant, making it susceptible to bacterial diseases and PM) 2) I will spray Serenade as a preventative instead of only as a treatment 3) I will have seedlings waiting in the wings 4) Last but certainly not least, I will continue to build soil health and mulch so that my plants are strong I found Serenade to be fairly effective, but once you have PM it is an uphill battle. Last year was my first year using it, and I was reluctant to use it unless I needed it, which may have been a big mistake. I am also considering kaolin clay....See MoreIdeas for trellis for out of control watermelon/squash?
Comments (10)I have lots of stuff getting attacked by powdery mildew but so far the squash and zucchini are producing anyway. As for a quick and easy trellis idea. I like to use the cattle panels from tractor supply. You can leave the whole 16' length (they are about 4' wide) and make an arch and secure it with stakes or posts. Or you can cut into sections and stab the pointed ends into the ground and make a sort of fence with it for the plants to climb. I like to take sections of it and zig zag them and tie them together to give them more strength and stability. As to growing pumpkins and watermelons up a trellis, hum. You might have to use some fabric to make hammocks to support the fruit because I doubt the vines could handle that. cantaloupe might be able to support it's own fruit, I'll soon find out since I seem to have had several cantaloupe plants sneak in with my cucumbers and climb the trellises. Here is an example of the arch with a cattle panel Here is a link that might be useful: TCLynx...See MoreSuggestions for white powdery mildew on pumpkins and squash
Comments (9)"That is caused by sprinkling water over your plants, only water the soil to avoid this." That is actually incorrect. Powdery mildew is not encouraged by wet foliage - in fact, its spores will not survive in contact with any moisture and one way to discourage the development is to spray down the plants frequently but early in the day so foliage has time to dry (other problems can be created by wet foliage at night). The primary concerns are proper air movement, so avoid overcrowding; and maintaining proper humidity....neither too high nor too low, both with respect to ambient humidity and with soil humidity....See Moreseysonn
