Why Plants Get Yellow Leaves?

There are many reasons why plants get yellow leaves: too much water/too little water, too much light/too little light, too much fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small./too little fertilizerPlants need fertilizer only when they are actively growing.

If a ficus tree or a schefflera doesn’t get enough water, it develops bright yellow leaves. If a peace lily or pothos gets very dry and droops, the next time you water, a few leaves on the plant turn bright yellow. The important thing to remember is that yellow leaves mean different things on different plants. What works for one house plant doesn’t work for others.
