Property owners who value their landscaping want their trees to grow in a healthy manner and look beautiful. You may think fertilizing routinely is the best approach and even seen your neighbors fertilizing. And yet, you might still be wondering if you should jump on the fertilizer bandwagon, “If they’re doing it, should I be doing it to?” Believe it or not, routinely applying fertilizer to your trees is rarely the best approach. In fact, there is no clear-cut answer on the best fertilizing regimen.

Signs It Could Be Time to Fertilize Your Trees

As we mentioned, knowing when and if to fertilize is tricky. There are no giant, flashing arrows that point to the trees that need a little extra nutrition. Fortunately, psychic powers are not needed to know when fertilizing might be a good idea. There are some indicators that can be easily observed.

Green Is Good: You should expect your tree to have green leaves or needles a vast majority of the time outside of fall or winter if it’s a deciduous species. If you start to see full or partial yellowing of leaves or needles during late winter through late summer, fertilizing might just be what the doctor ordered.

Keep a Close Eye on New Growth: Pay careful attention to any new growth. If the new growth seems smaller or just out of the norm compared to previous years, it may be time to give your trees some extra nutrients with fertilizer.

Pay Attention to New Shoots: If you are an observant landscaper, you may notice your tree does not have as many shoots of new growth as before. Taking a closer look at the buds may reveal bud scarring. Either of these two occurrences are strong indicators your tree may be in need of fertilization.

Trees Need Nutrients for a Healthy Immune System

The flu season has reached epidemic proportions. No doubt, many of us are taking extra care to be as healthy as we can to give our immune systems a much-needed boost. Trees are no different. The healthier a tree is, the more immunity it will have when it comes to battling pests and diseases.

If you are a weekend warrior who likes to spend time in your garden, you may know nitrogen, magnesium, potassium, phosphorus, and sulfur are key nutrients for healthy plants. However, this is only one part of the tree nutrient puzzle. The nutrients listed above are known as macronutrients. They are called macronutrients because healthy trees require them in large quantities. However, there are several micronutrients that play a big role in boosting a tree’s immunity. Micronutrients earn their name because trees generally require them in much smaller quantities compared to macronutrients.

Zinc, iron, and boron are a few of the key micronutrients that help keep your trees in fighting shape to combat pests and diseases. Finding a fertilizer with these ingredients will go a long way toward boosting immunity. Natural compost can also be a great way to deliver valuable micronutrients. Food scraps and garden clippings contain large amounts of the proper micronutrients. They also make an extremely effective and budget-friendly compost.
