Let’s start off with the basics – what is fertilizer? What does it contain? Fertilizer is any substance, natural (organic) or chemical (inorganic), that is added to soil or plant matter to increase its health and nutrient density. Majority of fertilizers contain the essential micro and macro nutrients that trees and plants need that might be deficient within the soil. Macro-nutrients are the substances needed in larger quantities, some which are found in air and water like Carbon, Oxygen, and Hydrogen. The three main macro-nutrients usually needed are Nitrogen, Phosphorus, and Potassium (Potash). Nitrogen being the most likely to be deficient in our soil. There are secondary nutrients which are less likely to be missing from soil are Calcium, Magnesium, and Sulfur. Micro-nutrients are nutrients needed in much smaller amounts like Zinc, Manganese, and Iron. All are important for healthy plant growth.
Well, for the same reason you would fertilize other plants, to help them grow healthy. Unlike trees growing in a forest, our urban and suburban trees have more stressors and deficiencies. While forests provide naturally occurring fertilization, due to animals and decomposing material found within their environment, our trees do not have those same opportunities. We tend to like clean looking yards and will rake up fallen leaves and chase off unwanted animals. By using a fertilizer, we can provide the much-needed nutrients that are deficient in our arid Southwest soil. When growing, trees need a steady supply of nutrients, and fertilizing accomplishes that. By supplementing the essential nutrients, we can assure that our trees will grow healthy and thrive in our Las Vegas landscapes. Fertilizers can also help trees protect themselves against pests and disease – mush like how eating helps our immune systems. Healthy trees are also better at withstanding damage from their environment, like damage from wind and caused by heat stress. It is important to fertilize our trees so that they can grow healthy and we can relax in their wonderful shade.
It’s important to have a regular fertilizing routine to ensure that you will continue to have healthy trees. We suggest fertilizing (unless it’s too hot) or using Moon Juice monthly to help with our warmer weather and dryer climate. If you want to have clarification or to set-up guidelines, don’t hesitate to reach out to our nursery pros at your local Moon Valley Nursery. They can help! Our custom-blended fertilizers are designed to trigger growth responses within the trees or plants, that way they can be used at any time, even after the ideal springtime growth season.
Here are some signs to look for that might mean you need to fertilize:
- Yellowing leaves that are smaller than normal. Overall growth is stunted – possible Nitrogen deficiency.
- Small leaves with scorched edges, may be purplish or blue-green in color. Leaves may fall early. Overall growth seems weakened and reduced – possible Phosphorus deficiency.
- Tips and edges of leaves are yellow and look scorched with brownish-purple spotting underneath – possible Potassium deficiency.
- Leaves turn dark starting at the base and going outward then die – possible Calcium deficiency.
- Leaves are yellow between the veins which stay green – possible Iron deficiency.
- Center of leaves turn yellow or reddish in color. Dead spots appear – possible Magnesium deficiency.
- Upper leaves turn yellow in the center between the veins – possible Manganese deficiency.
- Veins are a lighter color than the tissue in between – possible Sulfur deficiency.
