What Is Fertilizer?

Can you fertilize trees in summer? Before diving into that question, let’s quickly cover the basics. Fertilizer is any natural or chemical substance added to the surrounding soil or directly to a plant to boost its vigor.

Most products you find at your local gardening store contain these macronutrients, the substances trees need in large quantities:

  • Nitrogen: This element is a key component of chlorophyll, which allows plants to turn sunlight into energy. Feeding it to a deficient tree will likely encourage denser foliage and faster growth.
  • Phosphorus: Phosphorus aids the root development of shrubs and trees for improved water and nutrient uptake
  • Potassium: With healthy potassium levels, plants’ cell walls better resist insect attacks, diseases, drought, and other stressors.

Trees also require smaller amounts of micronutrients such as magnesium, sulfur, and iron.

How To Spot the Need for Summer Tree Fertilization  

Can you fertilize trees in summer? Absolutely. It’s an excellent way to protect your specimens from heat stress and keep them thriving. We recommend doing it at the start of the season before the weather gets too hot.

If you’re considering fertilization as a way to target specific issues, take great care to diagnose them accurately. Here’s a general guideline:

  • Overall stunted growth with small, yellowing leaves: possible nitrogen deficiency.
  • Yellowing leaf tips and edges and brownish spots underneath: possible potassium deficiency.
  • Prematurely dropping foliage or small leaves with scorched edges and purple and green coloration: possible phosphorus deficiency.
  • Leaves darkening from the base outward before dying: possible calcium deficiency.
  • Unusually pale leaf veins: possible sulfur deficiency.
  • Leaf centers looking reddish or yellow: possible magnesium deficiency.
  • Yellowing leaves with green veins: possible iron deficiency.

While these symptoms may hint at nutrient deficiencies, they can also stem from pests, diseases, or environmental factors. Instead of playing guessing games, why not let a specialist pinpoint the exact issue and solution?

Smart Fertilizing Tips for Healthy, Summer-Ready Trees

If you want to boost soil health and your trees’ growth, incorporate these steps into your care routine:

  • Always start with small amounts, preferably a slow-release fertilizer, to minimize the risk of over-fertilizing.
  • For an even safer approach that also improves soil structure, consider organic options like compost or well-rotted manure.
  • Apply the product evenly around the drip line, avoiding direct application near the trunk.  
  • Water the area thoroughly afterward to help nutrients soak into the soil.
