Yes, too much fertilizer can lead to yellowing leaves, a condition known as fertilizer burn. This occurs because an excess of certain nutrients, especially nitrogen, can harm the plant's roots, reducing their ability to absorb water and other essential nutrients. To prevent this, make sure to apply fertilizer according to the package's recommended rates and consider using slow-release formulas that reduce the risk of overdose. If your plants are already affected, flush the soil with plenty of water to help remove the excess fertilizer.
