I am in Birmingham, AL. Today I went to a local nursery I like a lot and chatted with them. They also think it's not a virus which was reassuring. They thought fungus and recommended an organic insecticide. Tonight I did some cleaning in the garden bed and applied the product. Inspecting again today I saw a lot that matched downy mildew descriptions, especially having some grayish brown patchy spots of mold. Also the brand new leaves do not seem to be affected which seems good. We are careful to water at the base of the plant but it has been very rainy and VERY humid lately. Should the insecticide soap help? Or are there other treatments that would be better?

My cucumber plant has died completely at this point. Can downy mildew do this or might the culprit there be something different?

Thanks for the comments! I have browsed the forums a lot but this is my first time posting so I'm excited to participate!

95% of the time yellowing leaves = too much water or fertilizer related. if it starts out on the leaf tips its typically too much nutrients. if it starts like pale the center and progressing outwards its typically low nutrients. best bet is to check what you've done and haven't done. ;)

I live at the beach and it washes up on the beach at high tide. I can pick up all I want. I use it mainly for trace minerals and mix with compost. I noticed yesterday that there were several varieties of seaweed I haven't seen before.-

I use the maxicrop and and can vouch for it . I start a lot of cuttings inside over winter. Every 10-14 days I drench the pots with it and the leaves stay green all winter. It is not a fertilizer but it has lots of nutrients/minerals the plant can use. It seems to make a difference. Outside you most likely need to use it more often like at least once a week.

Why would you? If you are growing them for normal storage then all those in the pic are still healthy, green, and growing. Sure you can pull a few if you need them to use now - those few in the center with blooms on them for example - but the rest are no where near harvesting. Let them keep growing until they dry and turn brown.

I've got some hot banana plants growing, picked some when they weren't quite ripe, not hot at all. Started leaving them on the plants a lot longer, now they have a little heat to them. Have given some to a friend and she told they were pretty spicy and she eats Thai peppers all the time

Disclaimer, I prefer Hot Banana over Hungarian wax, by just a tad and for a different reasons, i've been eating and growing them both my entire life.

But otherwise it's fairly well known that Hot Banana has a lot of heat variance, and many of them will barely give you a tickle even when ripe. Whereas Hungarian wax, heatwise, is more reliable and predictable.

Bt strains are very host specific....there are strains that claim to be effective on certain beetle larvae but you'll have to research carefully to obtain the right kind.

Bt varieties used for caterpillars or fly larvae will NOT work on beetle larvae.

neem oil is probably the only thing i would use. it can be used as foilage spray or soil drench. in fact, the best properties of neem oil is the fact that it doesn't kill insects directly, but stops them from reproducing. so it should work wonders to eliminate the source (larvae). i would go with the concentrate neem oil extract, it's 70% neem oil and 30% emulsifier. use it at about 2 tbsp per gal.

I've grown them this year on tomato cages. They are nice and crisp with thin skins. The cucumbers/melons are long and pale green in appearance. This is the first time I've grown them in probably 10-15 years. It definitely won't be the last time but it's not a garden regular as space is limited.

I'm also growing a true cucumber called Japanese Climbing. It's a good slicing cucumber that has enjoyed climbing up the tomato cages. I've harvested several 9-12 inch fruits from the vines. This is the second year I've grown this heirloom and it's now considered a regular in my garden. I'm about ready to process seeds from a 16-inch long cucumber that I've allowed to mature.

Ok so basically don't do anything but keep fertilizing and they will flower/fruit in time? Do you cut the top off your romaine or is it cool if it grows so tall? I noticed the romaine in your pictures don't have tall shoots on them.

They will when they go to seed. I turn them under way before that. The eggplant should be ok with a little fertilizer and adequate water

As noinwi said previously, the silvering on the leaf veins was natural. However, you've got that plant in a relatively small pot for a zucchini and it was probably rootbound when you initially posted (due to the way some of the leaves have begun wilting). Since then it has only gotten more rootbound. Add to that the fact that you "barely fertilized" only once and you've got a plant that is severely stressed and more prone to pest/disease issues. Sorry to say but your plant is a goner at this point.

Many of those small flying creatures are types of wasps, that do things like prey on caterpillars and other things that we don't like. The reason we avoid using pesticides is to protect these things so they can do all the hard work in the garden to get rid of things that want to harm our gardens. Spraying pesticides on them is a bad idea.

Joe,

I know what you mean by the terrier destroying things. They have a laser like focus once they start tracking a critter.

Not to sound like a alarmist, check with your vet if "lepto," leptospirosis is a problem in your area. Check this link out Lepto

The dogs can get it by sniffing or ingesting rat urine. After my sister lost her dog to it we had our dogs vaccinated for it.

Dog disease from rats

A few years back I saw on National Geographic's where people are taking their dogs on organized rat hunts in big cities. They make a event of it and it is all done at night when the rats are active. Kind of like a tiny dog coon hunt.

My neighbors have cats. While I shoo them out of the actual garden (mostly because I don't want them using the mulch as a litter box,) I don't discourage them from roaming the rest of my yard. The rodent population is kept well in check.

Well, it sounds like you have incentive lol. If you do decide to keep it, and it sounds like you will, then probably the best thing you can do is avoid touching the sick one before the others. It could still spread through the air or through insects, but physical contact is something over which you have control.

Also, while zucchini aborts for a number of reasons, the easiest prevention is to hand-pollinate. If it hasn't yet been discussed above, and if you aren't sure how, just take a male blossom (it will be a flower atop a single stalk with a pollen covered stamen inside) and remove the flower petals, leaving behind the little nub (stamen) covered in pollen. The female flower will have a cluster of about 5 'nubs' (stigma) inside the flower and will sit a top a tiny zucchini fruit. Just take the de-petaled male flower and, pretending you're a bee, gently rub it around the stigma. That's it. Easy as can be. If there are just a few male flowers, you can use one male to pollinate a few flowers, just be sure to keep a little pollen on the stamen.

Good luck.

I actually did hand-pollinate but it was somewhat wet on those mornings and I know that can affect how well it works. I figured they were aborting due to stress, but I suppose it could be a pollination issue. It's supposed to be drier for the next week or two so I'll keep trying on the new ones.

I'm in AZ. It is in full shadow the last couple hours of the day.

Probably not. If you've got it by the west wall, it will get eastern sun and shade in the afternoon, which is what you want. Unless it is something that can handle the scorch of the afternoon, the rule is to plant it on the east side of buildings and walls. Watch out for heat radiating off the wall, so plant it 2-3 feet away to allow for some air movement. The descriptor for plants that it "loves sun" is not intended for people who garden in the desert. Almost nothing loves the sun here and gardening is a partial-sun activity.

IMO row covers are the best invention for gardeners since pockets on a shirt. For years I used BT, and it NEVER gave the protection that row covers give. And so much easier!

This is the cabbage I just harvested in the peak of summer with only Bt treatment.

Of course YMMV and we all have different experiences. Bt only protects against caterpillars, it doesn't help against other pests.

If you don't remove the infected foliage from the plant and dispose of it away from the garden the fungus just continues to spread even with fungicide treatment. So the first rule of thumb is to never leave damaged foliage such as that on the plant. Then use your fungicide sprays.

They are way too big to be fire ants. I am plagued by them in my house. I just get rid of them and a few weeks later they are back. I have to be careful with chemicals because I have a cat.

Look for aphids,too. Lots of ants farm them and keep the good bugs away. Watched a great movie about insects that had excellent footage of them fighting off good bugs.

The desert fire ants in AZ were just as bad as the fire ants in NC and OK. I now live in NC, hate those buggers!
