No, it’s not a new brand of mouthwash.
If you notice chlorosis on any of your plants, ask yourself the following questions:
If the plant is being watered properly and getting enough sunlight, the problem is probably a mineral deficiency. The only way to really know what is in your soil is to send samples to a local, reputable lab. Over-the-counter soil tests are generally a waste of money.
When I submitted soil samples to the Extension office, I learned that my soil has an abundance of every nutrient known to humankind, except iron.
Plants use iron to process nearly every other nutrient, so it is critical to healthy plants. Unlike nitrogen, which can move freely within a plant, once iron is absorbed, it stays where it is. You can add iron to the soil or, for faster results, you can apply foliar (leaf) sprays. Low levels of zinc or magnesium can also cause chlorosis, as can certain pathogens, the wrong pH, or compacted soil.
As soon as your plant has adequate sunlight, the correct amount of water, healthy soil, and sufficient iron, its little energy factory will kick right in and everything should start greening up pretty quickly.
