Hello, this is Tanner Collier, the Horticulture Agent with Burke County Cooperative Extension. Our program today is about “Blossom Drop.”
As the growing season continues, people may notice an odd occurrence happening with their plants. The plants look healthy and lush, but the flowers die, fall off, and no fruit forms. This condition is called blossom drop. Blossom drop commonly occurs in tomatoes, beans, peppers, and various other garden plants. Blossom drop can be caused by several factors, such as high temperatures, excessive nitrogen fertilizer, and windy conditions.
Do not over-apply nitrogen to your plants. Fertilizer should only be applied when needed. Blossom drop is not caused by a nutrient deficiency, so applying additional fertilizer will not help. Remember, more fertilizer does not necessarily mean a healthier plant.
Air temperature is the main cause of blossom drop. When nighttime temperatures are warmer than 75 degrees or cooler than 55 degrees, blossoms may start to fall off. Daytime temperatures of 90 degrees and above can also cause blossom drop.
There are a few things you can do to help prevent blossoms from falling off. Mulching around your plants can help retain moisture in the soil. Windbreaks can also help protect your plants from constant, strong winds. Ultimately, it is best to play the waiting game until the weather changes to more favorable conditions.
