Why Your Tomatoes Aren’t Ripening (It’s Not What You Think)

Why are your tomatoes staying green even though they’re full size? If you’ve been waiting for ripe tomatoes that never seem to turn red, the answer may have nothing to do with fertilizer or pruning. In this video, I explain the science behind tomato ripening and why high summer temperatures can temporarily slow or stop the process. We’ll cover what ethylene actually does, why potassium isn’t the miracle solution many gardeners claim, whether pruning helps, and how nighttime temperatures influence ripening. You’ll learn: Why tomatoes stop ripening during heat waves The temperature where lycopene production slows How ethylene triggers ripening Whether bananas really help tomatoes ripen The truth about potassium fertilizers Should you prune leaves to expose fruit? When to harvest mature green tomatoes How to finish ripening tomatoes indoors If your tomato plants are healthy but your fruit just won’t change color, this video will help you understand what’s actually happening—and what you should (and shouldn’t) do about it.

In the long summers as a child, she would garden alongside her grandmother and it was then that she realized her love for greenery. With years of great studying, Ashley had begun her post-secondary education at the University of Saskatchewan. At first, her second love, animals, was the career path she chose but while doing her undergrad she realized that her education would take her elsewhere. And with that, four years later she graduated from the University of Saskatchewan with a bachelor’s degree in science and a major in Soil Science. Some of Ashley’s interests are YouTube, in which she posts informative videos about plants and gardening. The focus of Ashley’s YouTube channel is to bring science to gardening in a way that is informative but also helpful to others learning to garden. She also talks about the importance of having your own garden and the joys of gardening indoors. Ashley continues to study plants in her free time and hopes to expand her YouTube channel as well as her reach to up-and-coming gardeners.
