Why can't my tree stay healthy on its own?

Why do we need to fertilize our trees?

Living outside of their natural environment, trees (and other perennial plants) can have a hard time maintaining a balanced diet. Often grass is growing around our trees, and this causes several challenges for them throughout the growing season, including nutrient availability. Adding specific fertilizers can help boost a trees health to endure the tough urban environment, and stay healthy through the long winters.

How do you add fertilizer for the trees?

Several techniques can be utilized; deep root irrigation, upper layer or surface applications, trunk injections or compost spreading are the most common methods used, and it can depend on the ground cover and environment that the trees are growing in can help dictate what's best for your tree.

How often does a tree need fertilizing?

If you are using mulch and companion plants under the canopy of your tree, you may be cultivating a rich soil ecosystem that doesn't need fertilizing. But if you have grass around your tree, or other unnatural elements to the environment, then you might need fertilizing annually, or sometimes biannually depending on circumstances.

How do you know what to use ?

Soil testing is recommended for targeted results, but fertilizers used are formulated for the trees requirements depending on the season and symptoms. 

How do I know the fertilizer is working?

Illustrated progress of foliage colour, twig elongation, insect/disease damage can indicate clear before and after pictures of relevant issues that the trees are overcoming, but sometimes nature works in mysterious ways and some visual representations of fertilizing is impossible to show. Adding the nutrients to the soil is step 1, but we can't decide what the tree uses them for specifically once consumed.
