Fertilizer is one of the most important parts of a normal home gardening. Because Science! The three main ingredients of fertilizer are (P), nitrogen, (R), and potassium. All three main ingredients work together to make the nutrients in the soil that plants need to grow.

Potassium is one of the main components of fertilizer that is usually sold in bags or powder form at your local nursery or garden store. If you do a lot of lawn fertilization, you will find that it comes in a premixed form that already has all three major nutrients in it. In addition, it usually comes in a granular form with small granules of potassium. A premixed bag or granule will have more potassium than a granular bag or powder because the granules are larger.
Numba – This is the brand of fertilizers that my husband grows and uses in his lawns and gardens. He says that Numba does a great job of breaking up clumps of soil that will help the grass to absorb more nutrients. It also helps the grass to break down the nitrogen that is in the soil. This is why our lawns always look so healthy even though we fertilize them about four times a year.
Phosphate is the third ingredient in fertilizer. It is usually sold as a powdery substance or a crystal. It is used as a conditioner for when plants are starting to bloom and as a trace element for lab tests. A Phosphate fertilizer should be about two parts to each one part of nitrogen and two parts to each one part of potassium.
There are also mulches that can be made from the main ingredients of fertilizer. One of them is the Joshua tree mulch. This mulch is made by soaking the Joshua tree leaves and needles in water, allowing them to soak through to the soil, then raking them into the pile. The mulch can last for years if properly cared for, but should not be applied to newly installed lawns or vegetables.
Fertilizer should be applied to the soil in generous amounts. Gardeners who over-fertilize their soil will often find that their plants do not grow as well. Over-fertilizing can result in depleted soil that will not retain enough water or nutrients to sustain a healthy garden. If you are unsure as to what ingredients of fertilizer should be used on what type of soil, contact a professional at your local nursery.
