Growing zucchini for the first time? Well, buckle up my fellow gardener, because you are in for a ride!
I remember the first time I grew zucchinis; I was just strolling through my garden, admiring the lush greenery, when all of a sudden I spotted brown patches all over my zucchini plants!
I was panicking and wondering what went wrong, but quickly realized that all this worry was getting me nowhere. I decided to play detective and unravel the mystery of brown zucchini leaves. And that’s when I discovered: Alternaria leaf spot.
This is a fungal disease that is often found among cucurbit plants, so your cucumbers, zucchinis, watermelons, pumpkins, and squashes aren’t safe. The tricky thing is – you can’t completely get rid of it.
Your only options are to control the disease or completely throw away your precious plants.
What will you do? I suggest reading more about Alternaria leaf spot before making any decisions!
Alternaria Leaf Spot Might Be To Blame
Those sneaky brown spots playing hide and seek among the leaves of your zucchini plant might mean that your plant is suffering from Alternaria, or it might be something else completely.
If those spots resemble bull’s eyes or knotholes in the wood when you take a closer look, that’s when you know Alternaria has started spreading.
This mysterious disease doesn’t just stop at the leaves – oh no, it can even crash the fruit party. Fuzzy lesions on your zucchinis, or even sunscald, might appear if things get really wild.
I made a mistake and didn’t harvest them soon enough, so they were all completely ruined. Learn from me and harvest those zuccs if you see even the tiniest brown spot!

Although It’s A Tough Cookie, You Can Learn To Control It
Prevention is key when it comes to keeping those pesky brown spots at bay and saving your zucchini plants from a leafy disaster.
Alternaria leaf spot thrives on moisture, so let’s show it who’s boss by keeping things dry and cozy in the garden.
You might also consider mulching.
This is like a secret weapon for your plants, preventing water from splashing around and creating the perfect breeding ground for this sneaky disease.
If you tend to overwater your plants, drip irrigation is the way to go (it keeps those leaves high and dry where they belong).
What helps my zucchinis the most is crop rotation.
By rotating your cucurbit crops, you’re basically avoiding Alternaria because it likes to hang out in one spot for a couple of years.
And if you do see any brown spots sneaking around, don’t panic!
Simply bid farewell to the infected plants (plastic bag and trash can, please) and keep them far, far away from your compost.
If all else fails, don’t be afraid to bring out the big guns: fungicides.
They are here to save the day when things get tough. Just remember to follow the label instructions like a pro, and your zucchinis will be back on track!
Please remember to stay calm and rational (don’t go into crazy mode like I did).
Take a closer look and see if it might be an Alternaria leaf spot. Remember, prevention is key, so mulch, rotate your crops, and keep your plants well-watered without overdoing it.
