One vegetable gardener sought help after finding their zucchini plant in an extraordinarily gnarly condition they couldn't identify.
Once a photograph of the base of the plant was shared on Reddit, other gardeners identified the problem as an especially bad infestation of squash vine borer.
Here's what to know
The gardener and original poster wrote, "My zucchini has not been producing well this year but has been looking very healthy and getting huge. I was thinking about pulling it out to make room for something else and when I got down to look at the stem, I saw whatever the hell this is. Any ideas?"
Almost immediately, other gardeners added their two cents, converging on the conclusion that this was a nasty case of a squash vine borer infestation.
These pests burrow into squash and zucchini stems, disrupting the plant's ability to move water and nutrients. That can leave gardeners baffled when a plant still looks vigorous on the outside but suddenly stops producing well.
One commenter wrote, "This might be the worst case of SVB I've seen."

Another responded, "I am impressed that the plant is still alive."
A third gardener added, "I am in Illinois too, and the squash borers completely decimated all of my zucchini plants."
More background
In many cases, gardeners do not notice vine borer damage until harvests begin shrinking or the plant starts collapsing altogether.
This makes early detection crucial. Checking stems near the soil line, watching for sawdust-like frass, and monitoring plants that suddenly stop producing can help catch squash vine borers before the damage gets out of hand.
Crop rotation and removing infested vines can also help reduce future pest pressure. While no method is perfect, staying vigilant can make a major difference for gardeners hoping to keep summer squash productive.
Avoiding these infestations can come with real benefits. A productive vegetable garden can help cut grocery costs, especially for pricey seasonal produce items. Many gardeners also say homegrown fruits and vegetables taste better than store-bought options because they can be picked at peak ripeness.
