Fall Tree Care: Replenish Lost Nutrients With Fertilizer

September 18, 2015
Topics

Take a walk through the woods, and you’ll likely find yourself surrounded by tall, healthy trees—nature’s beauty in full effect. Achieving such majesty doesn’t come easily for trees in your backyard though. 

But why?

Yards are a much more challenging environment for trees.

Soil found on the forest floor is rich in nutrients that come from fallen leaves and twigs. When we remove those leaves from our yard, the soil on our property has fewer nutrients to offer. Combine that with the fact that trees are competing with hungry lawns and other plants for resources, and it’s a less-than-ideal situation for growth and development.

Much like we use fertilizer to keep our lawns healthy, applying a slow-release fertilizer to the ground around our trees during the fall offers these four benefits: 

  1. Replenishing nutrients lost during the summer.

  2. Decreasing stress on trees, making them healthier and more capable of resisting diseases and insects.

  3. Supporting healthy, deep roots that anchor trees.

  4. Promoting healthy growth in trees, with improved size and color.

So, how do you choose the right fertilizer for your trees?

Through extensive research and testing, Davey Tree has found that the ideal tree fertilizer contains a very similar makeup of nitrogen, phosphorus and potassium as the natural soil found in the forest. Look for a product that includes: 30 percent nitrogen, 10 percent phosphorus and 7 percent potassium. This typically is listed on all packaging as “30-10-7.”A slow-release fertilizer is also preferred, as it will feed your trees over an extended period.

Fall is the perfect time to fertilize your trees. Contact your local Davey arborist to schedule a free consultation.
