The Scoop on Fertilizer for Your Trees

The Scoop on Fertilizer for Your Trees

Just because Mother Nature has blessed us "lucky ones" with a few last-minute (perhaps unwelcome) snow storms, doesn't mean we can't be excited for what we consider to be a normal, pleasant spring--a very close, yet foreign, concept for some.

Like many outdoor lovers in early spring, you're probably looking forward to a prosperous growing season. You're dreaming about bright, beautiful blossoms; luscious, green grass and fragrant, thriving trees. We bet you can't wait to soak up some sun rays as you witness the fruits of your labor begin to take root in the soil and grow tall and green for all to see.

However, warmer weather isn't the only solution to happy, healthy trees. Without proper nutrition from the soil, trees and plants will not grow to their fullest potential. "The best soil combination is not much different than that of a natural forest setting," explains R.J. Laverne, board certified master arborist and Davey's manager of education and training.

Because many organisms living within the forest floor break up the organic material that accumulates at ground surface, as well as absorb rainfall, plant roots receive more oxygen and grow healthier as a result. According to Laverne, landscape trees miss out on those benefits because property owners often haul away leaves in fall, and trees compete for water and nutrients as they mature.

Davey's professionally trained arborists can help you determine whether fertilizer is appropriate for your landscape, and, if necessary, they'll apply it to your trees.

While the forest floor is an ideal setting for all plants, we realize not all landscapes have access to such nutrient-rich soils. But throwing down fertilizer shouldn't be your immediate, go-to solution for healthy trees, either. So, before you assume fertilizer is your best option, first ask yourself the following questions:

  1. What are you fertilizing?
  2. How is the health of your landscape plants?
  3. What are your goals for the plants in your landscape?
  4. Which type of fertilizer would you use?

"Fertilizers are like vitamins for your plants," explains Rex Bastian, technical advisor from the Davey Institute. "If you take a vitamin once a day, for example, it won't hurt you, but it won't necessarily do a lot for you and your health."

And like humans, trees and plants need nutrients--which fertilizers do provide--but providing more nutrients than readily available is not necessarily better. "Certain conditions can be addressed with proper, supplemental nutrition, while others cannot," Bastian explains.

Davey's professionally trained arborists can help you determine whether fertilizer is appropriate for your landscape, and, if necessary, they'll apply it to your trees and shrubs before they enter peak growing season.

Just like that, we eliminate all the guesswork from the equation and you can breathe easy knowing your trees are in our hands. Contact your local Davey office today for a free consultation!

  • The Tree Doctor February 16, 2015 >Thank you for reaching out, Cynthia! Yes, you should first apply the compost, then apply proper organic mulch, which may include shredded hardwood bark or pine needles. It’s best to first apply the compost, then let it work its way into the soil via rain or irrigation before applying mulch at a later date. We hope this helps you!
  • Cynthia B February 9, 2015 >We have an organic compost pile. Should we spread this compost around trees and shrubs in spring? Then add mulch on top of this?

  • Root in Moisture

    Planting trees is just half the battle.

    The diseases, pests and power equipment that emerge outdoors in spring, accompanying frequent sunlight, longer days and warmer temperatures, can wreak havoc on your trees if you don't put forth the effort to protect them.

    To keep your trees healthy throughout the growing season and beyond, you must practice routine maintenance and proper tree care. One way to help trees retain moisture, reduce weeds and keep power equipment at a safe distance is through mulch. In the coming weeks, you'll see piles of fresh mulch lined along neighborhood driveways. Soon, the coarse, fragrant matter will settle among flower and tree beds, enhancing the quality of landscapes' appearances.

  • Just a Trim, Please

    Put a pair of scissors in your hands, and whether you're cutting coupons or bangs, there's always the potential to oversnip. It's almost too easy to make a mistake as you clip, clip, clip away - removing a little more on this side and a bit more on that side.

    Just like with a bad haircut, there is nothing more noticeable than a poorly pruned plant - pieces sticking out in all directions, a butchered shrub, a tree that looks like the top has been sliced off. The good news is that just as the perfect haircut can frame the face and improve a person's appearance, the same can be said for a professional tree pruning job.

    Pruning is not only a science, but an art form. The science aspect of pruning involves understanding tree biology, recognizing plant flaws and skillfully eliminating or minimizing defects. The artistic aspect of pruning consists of removing dead wood while aesthetically shaping the tree.

  • Heat Wave

    Heat wave.

    The term usually makes many people think of the tropics or the desert.

    But extreme heat has hit many areas hard so far this summer. Record highs have been broken in some cities, while others have seen their hottest temperatures since the 1980s.

  • Forecast: Hot & Humid

    The air-conditioning is set on high. The fan is blowing in my face. And it feels so good, particularly since my dog and I were just panting within seconds of stepping out to a heavy wall of heat and humidity. His face tilts up to mine, happy for the nice, cool breeze. We face the facts together as I sip from a tall, cool glass of water and he laps up the same out of his bowl: Despite our yearning to enjoy the outdoors, it's hot. And it's hot in nearly every region of the country.

    There's simply no denying it: This summer's a scorcher. While it's difficult to find the motivation to open the door to the heat lingering in the air outside - let alone step out onto a dry, parched lawn - I brave the elements because I notice my trees need some TLC, too.

    It's difficult to imagine another day of 90-plus degree temperatures. So I can hardly imagine how my trees must feel as their roots cling to nothing but the dry soil, day after day.

  • Try a Little Tenderness

    When someone moves into a new home, they tend to have a smoother, more successful transition when they plan ahead and carefully move through each step. This includes thoughtfully packing boxes beforehand in an organized fashion, clearly labeling the boxes so movers put them in their proper rooms and then unpacking them so everything that is removed is unwrapped and put into its place to avoid rework.

    If this works for your most delicate China place settings and Lenox crystal, you can see why it would make all the difference when moving something as large, yet just as delicate, as a tree.

    When it's a big, valuable tree that provides numerous benefits to your landscape and your family, a "move" is much more than just picking it up and placing it in its new location. To preserve the numerous benefits trees provide to a community and its residents, which The National Tree Benefits Calculator can help determine, one must plan carefully - before, during and after the big move - to ensure survival.
