My tomato and pumpkin leaves

[ChrisC_77]

I am a little concerned about one of my sugar pumpkins. Not sure what this one is. My neighbor has this also ona different pumpkin variety.

Also, my celebrity tomatoes are started to curl a bit. Not all of the leaves. But some. Last watered Tuesday. Leaves look lush and healthy otherwise. Does not appear to from lack of water. Fruiting and blooming like crazy. (About 50 blooms/fruit per plant) I wasn't going to water today as it is supposed to rain tomorrow.

On the pumpkin leaves both the one pictured and my other one that has powdery mildew I sprayed yesterday with one gallon of water mixed with 2 tablespoons of white vinegar. I heard this was a good thing to use.

Did the pumpkin leaves not look like that before you sprayed?

I don't grow pumpkins, but I know a number of squash varieties have silvery markings as a normal part of a healthy leaf:

But no vinegar wasn't a good thing to put on it. Vinegar is herbicidal, we recommend it as a home made weed killer. Treat your powdery mildew with baking soda solution, hydrogen peroxide, or diluted milk. (But pick one or alternate treatments when you renew them; don't mix.)

What has your weather been like? Tomato leaves tend to roll up like that when it is hot and dry. It is called physiological leaf roll and it is a protective mechanism to keep the leaves from losing too much water.

The pumpkin leaves looked that way before I sprayed. Not all of the leaves look like that. At least half do. It is the small sugar pumpkins.

If it's not been long since you sprayed the vinegar, you could try to wash it off with just water.

You may want to educate the source that told you vinegar is good for plants. It's like all natural roundup.

but the vinegar did not make the markings which were already there. I think your pumpkin leaves are just fine, that is just a natural marking. If you look at the picture of the healthy squash leaves that I posted, you can see that some of the lower leaves don't have the markings.

Although it was not a good thing to do, in this case the vinegar may not have harmed it.

I agree, that is normal for some squash and pumpkins.
