Before You Add Fertilizer, Watch This

Yellow tomato leaves don’t always mean nitrogen deficiency! In this video, we’ll break down the science behind why tomato leaves turn yellow, how to tell the difference between nitrogen, magnesium, iron, natural aging, disease, watering problems, and transplant stress, and why adding fertilizer can sometimes make the problem worse. As a soil scientist, I’ll show you how to correctly diagnose yellow leaves before you spend money on products your plants may not even need. By understanding where the yellowing starts and how it spreads, you’ll be able to identify the real cause and grow healthier, more productive tomato plants. In this video you’ll learn: 🌱 Why older vs. younger leaves matter 🌱 When yellow leaves are completely normal 🌱 Signs of nitrogen, magnesium, and iron deficiencies 🌱 When fertilizer helps—and when it hurts 🌱 The biggest mistakes gardeners make when diagnosing yellow leaves 🌱 Science-based solutions that actually work If you enjoy evidence-based gardening, subscribe for new videos every Wednesday, Friday, and Sunday! #tomatoes #gardening #vegetablegarden #gardeningincanada #soilscience #plantnutrition #nitrogendeficiency #tomatoplants #gardeningtips #growyourownfood #organicgardening #containergardening #planthealth #yellowleaves #gardenscience Helped Design A Plant Sensor!

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.
