  • Why are my squash leaves turning yellow?

    Created by Gwen on

    Why are the leaves becoming pale and yellow. They are in a grow box, in new potting soil, with fertilizer and mychorrizae added.

    Hello Gwen –

    Without high quality pictures or a plant sample, it may be nearly impossible to give you an exact answer​ as to what is wrong with your plants. My best guess would likely be over watering or over fertilization. Overfertilization will cause the plant to “burn” and has the potential to create an imbalance in the nutrient uptake of your plants. Consider flushing with water to remove any excess fertilizer solubles. The yellowing may also have something to do with the pH of the soil. Nutrient uptake is maximized when the soil pH is between 6.2 and 7.3. Keeping your soil pH within this range will encourage the plant to uptake nutrients quicker. Additionally, you could add a product such as Azos to help nutrients break down quicker into a more readily plant available form.

    Hope this helps!
