Trees require certain nutrients in order to function and grow. Most trees in urban landscape settings are grown in soils that do not contain sufficient nutrients for it to grow and develop properly. This is why fertilization is a very important part of tree care and tree preservation.Why You Should Fertilize
We frequently remove fallen leaves, organic matter and other potential sources of nutrient recycling that would naturally have helped trees thrive. Fertilization can replace these soil nutrients lost by leaf cleanup.
Tree fertilization can also help new trees expand root systems for better anchorage and overall vitality. Expanded root systems mean better water absorption and better defense against drought and hot weather, which has become more common here in the Pacific Northwest.
For those who want that instant screen, fertilization will increase plant growth.
What’s the Difference Between Deep Root Fertilization and DIY Fertilization?
So, what’s the difference between deep root fertilization and DIY fertilization sold in stores? Most store bought fertilizers (especially for lawns) are quick release nitrogen that are high in salts. The salt can cause “fertilizer burn” which results in scorched leaf margins. Deep root fertilizer is a slow release, zero salt formula, that does not burn or cause drought stress for the tree. Injecting into the soil brings the nutrients to the root zone of the tree and helps deliver more fertilizer directly to the tree. This is especially good for trees in grass and planting beds where competing plants may absorb some of the fertilizer.
Know Your Numbers
It’s important to know what type of fertilizer will give the right balance of nitrogen (N), phosphorus (P) and potassium (K). This can be confusing for many homeowners.

The builder had been speculating on a property for some time, and in making their intentions for the property known, the city inspectors realized that this property would be losing most of its tree canopy to the renovation. The city made the suggestion to save a 25-foot tall Coastal Redwood tree as a way to mitigate some of the lost tree foliage on the property.
A woman came into Big Trees’ office one afternoon this spring and mentioned that she had a significant number of Rhododendrons that were lining her property frontage, and she was considering having them cut down. While she liked the privacy the trees gave, her property had recently been burglarized, and she felt the Rhododendrons were a part of the reason the thieves felt comfortable targeting her property.
The developer first contacted Big Trees in the middle of winter with an idea of transplanting some existing trees that were on a property. The trees were in the correct size range for the Big John 90-inch tree spade, and access was good to transplant the trees into the planned space.
