Are your zucchini leaves turning white and yellow all of a sudden?
Well…a few factors could be at play that may be affecting your vines negatively.
In this article, we’ll go over some of the possible causes behind discoloration in zucchini leaves and hacks/tricks you can employ to fix those underlying issues in the comfort of your home.
Zucchini Leaves Turing White & Yellow?
1. Pest Attack
Pest attacks are quite common in squash vines. Zucchinis, which are a type of squash, face threat in the garden from aphids, spider mites, and cucumber beetles that lurk around the crop and damage stems and leaves in no time.
One of the more common signs of pest infestation in a zucchini plant is leaf discoloration which typically turns the leaves a shade of white or yellow.
If signs of pest attack are apparent and discoloration is getting out of hand, you may want to introduce pesticides in the garden as needed.
Solution
Neem oil can be an excellent pesticide and you can make a spray out of it at home for even more convenience. Simply add 2-3 tablespoons of neem oil in a gallon of water, put the mixture in a spray bottle, and spray your zucchini leaves with it on a regular basis.
2. Nutrient Deficiency In The Soil
Nutrient deficiencies in the soil can be a culprit for leaf discoloration. Zucchini vines thrive in nutrient-rich soil, particularly needing nitrogen for overall growth and even color development.
Solution
Addressing nutrient deficiencies in the soil isn’t as complicated as people make it seem. Fancy fertilizers work but simple homemade compost does the job too. You can mix it in with the garden soil or add a few handfuls to a bucket of water and water your zucchini vines with it.
3. Diseases
Various fungal and bacterial diseases can contribute to discoloration in zucchini leaves. This can happen as a result of excessive moisture or just having poor air circulation around the vine.
Fungal diseases like powdery and downy mildew leave patches of yellow and white on zucchini leaves. If proper care is not taken and the issue is ignored for long, all leaves could eventually die.
Solution
First and foremost, always cut off the affected leaves and prune your vines to allow for better air circulation. To tackle the fungal disease, mix a tablespoon of baking soda with dish-washing liquid and put that solution into a gallon of water. Next, spray the whole thing onto the affected vine to slow down mildew growth. Neem oil can also be very effective here since it has powerful antifungal properties.
4. Neglect
This isn’t really a cause, instead more of a tip.
Neglect can be fatal to plants. Whether it leads to disease, rotting, or deficiencies, at the end of the day, not paying attention to something you yourself planted will bring trouble.
Your zucchini vines call for some love and care; they won’t just produce fruit out of nothing.
Solution
If you see discoloration in your zucchini leaves and know deep inside that environmental conditions are not to blame, then you are. The only solution to this problem comes from within. Treat your vines like a responsibility and look after them if you seek a good harvest.
