Should I cut the brown leaves off my zucchini plant?
When pruning zucchini plant leaves, take care not to remove all the leaves. Keep some leaves on the stem, including leaf nodes near the last fruit you want to keep. You can also cut off any dead or brown leaves that may be present. Do not cut any stems, as this will increase the risk for disease.
How often should I water my zucchini plants?
Water generously. Add about one inch of water, depending on the soil moisture. If it feels too dry, add an extra inch of water. When the weather is cooler in early spring, water your zucchini about once a week, increasing to two or even three times per week once with air temperature increases.
Should I cut off zucchini leaves with powdery mildew?
Pruning the zucchini leaves that are full of powdery mildew should be done by the base of the vine. Don’t worry about cutting them off. Any leaves below that lowest fruit can and should be removed even if they’re perfectly healthy. You don’t need those stinkin’ leaves.
Why do my zucchini leaves look moldy?
Squash leaves are notoriously sensitive to powdery mildew. This is one of the most common issues with zucchini and arises when leaves get moisture on them in warm weather, which doesn’t dry off in a timely manner. This moist, warm environment allows the powdery mildew to flourish.
How do you get rid of mildew on zucchini leaves?
Use this recipe to make your own solution—mix one tablespoon of baking soda with a teaspoon of dormant oil and one teaspoon of insecticidal or liquid soap (not detergent) to a gallon of water. Spray on plants every one to two weeks.
Why are my zucchini leaves turning yellow and dying?
When the leaves turn yellow, something is interfering with chlorophyll production, and this is a clear indication that something is wrong with your plant. A zucchini leaf can turn yellow from nutrient and soil imbalances, too much or too little water, damaged roots, lack of sunlight, and several diseases and pests.
Can I cut mold off zucchini?
Like the hard cheeses made without mold, dense fruits and vegetables are not easily penetrated by mold. The same rule of thumb applies to firm produce: cut off at least an inch around and below the mold spot (again, not touching the mold with your knife) before using.
Why are my zucchini leaves molding?
Blossom end rot is caused by poor cultural conditions, such as excessively salty soil, drought, over watering and plant crowding. The disease is more common in sandier soils, according to the University of California IPM.
