It improves the plant’s general health as well as stem and root growth, and it allows plants to convert light into nourishment through the process of photosynthesis. Acidic soils can make it more difficult for plants to absorb phosphorus, so it’s vital to measure the pH level before planting. Petioles, as well as the plant’s stems, begin turning purple or red. Young plants are particularly vulnerable to low levels of phosphorus. Older leaves of the young plants are affected first.
