BigTreeSupply.com: Benefits of Deep Root Fertilization

by Nancy Penrose

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.
