Healthy trees offer a host of benefits. They provide shade, attract wildlife, and boost property values. However, weakened or diseased trees can be unsightly and even dangerous.
You know your trees require proper watering, pruning, and nutrients. But does that mean you need to apply fertilizer? In this post, a top-rated tree service in Hickory, NC, answers the common question, “Do trees need fertilizer?”
Why Do Trees Need Fertilizer?
Trees get nutrients from the air, water, sunlight, and soil. In urban and suburban environments, however, trees face a host of factors that limit their nutrition. And because trees have been shown to improve human health, it’s in our best interest to care for them as we would care for ourselves.
We may trim or restrict their root system, pollute the air, plant them in low-quality soil, or remove leaves and other organic matter. This means tree nutrient supplementation is sometimes required for healthy tree growth.
Do My Trees Need Fertilizer?
Not every tree needs fertilizer. When evaluating fertilizing requirements for trees, consider the following factors:
Growth Stage
Mature trees in good soil have low fertilizer needs, while newly planted trees often benefit from additional fertilizer. Fruit-producing trees need more energy when flowering and setting fruit.
Soil Quality
Tree soil nutrition is a big component of overall plant health. Your soil may lack basic macronutrients like nitrogen, phosphorus, and potassium or micronutrients like manganese, sulfur, and copper. If it does, the importance of tree fertilization may be higher.
Tree Condition
In spring, most trees produce new branches, leaves, and flowers. If your trees have been affected by pests, disease, road salts, cold weather, or even pruning, they are also healing damage. To have enough energy to do both, they may need extra fertilizer.
What Are the Signs of Nutrient Deficiencies?
When evaluating tree fertilizer necessity, look for the following signs of nutrient deficiencies:
- Yellow, brown, or purple leaves (depending on the species)
- Twisted, undersized, or fewer leaves
- Lower annual twig or shoot growth
- Dying branches or branch tips
- Decreased flowering or fruiting
- Lack of vigor or trouble growing
Many of these symptoms can have several causes, including pests, damaged roots, or improper soil pH. A professional arborist can help you identify whether a nutrient deficiency or another cause is to blame.
What Is the Best Fertilizer for My Trees?
Once you have answered the question, “Do trees need fertilizer?” your next question should be, “What is the best fertilizer for my trees?”
Soil composition varies by region and even by yard. The right fertilizer for you is the one that addresses your soil’s specific nutrient deficiencies.
