Question #1: Do trees just suddenly died?
Trees are always giving us signs that something is not right. We need to be monitoring and looking for those problems to prevent tree death.

Question #2: Is planting a tree too high a common mistake in the urban landscape?
When you do not see root flares, you’ve planted a tree too deep. Planting too deep is the most common mistake that we see in the urban landscape. It causes long-term problems as the tree develops later in life.

Question #3: Do I need to fertilize my trees?
If your backyard is a forest, a tree’s natural environment, then you do not need to fertilize. You have the organic leaf litter on the forest floor, a very rich, arid environment. A lot of oxygen and water can get to the root system. You have falling debris, falling trees, falling branches; all break down and put the nutrients back in the soil.

However, the urban landscape where our trees are planted is a much different environment. We add grass over the root system of the plants. It acts as a sponge. The water source comes down as rain and that turf just soaks up the moisture before the tree can get it.

Incorporating a slow release fertilizer on an annual basis is a proactive approach to maintain and keep your landscape investment healthy.
• Provides nutrients that we’ve removed
• Aerates the soil
• Provides resistance against secondary issues, such as disease and insects
