Tree Fertilization Services in Vancouver, WA

Frontier Tree provides fertilization services to vitalize trees with all the nutrients they need to thrive. Fertilizer is best applied in early spring when trees are waking up from dormancy and starting to grow roots and shoots. This time of year is when there is high soil moisture. This is important as they need complete nutrition for all the processes involved in growing and photosynthesis.

Fertilizer can also be applied in the early summer to encourage growth if there is enough soil moisture and if it’s not too hot. It is best not to fertilize drought-stressed plants. Nutrition will not benefit them in this state. Fertilizing in the fall should be avoided. You don’t want to stimulate new growth on plants when they will soon be going dormant.

Signs that Your Trees May Need Fertilizing:

  • Yellowing leaves
  • Stunting – a tree has been growing very slowly or languishing
  • Growing smaller and sparser leaves
  • Earlier fall color and leaf drop

All these are signs that your tree is not thriving. There are a number of reasons that should be investigated as to why a tree may display one or more of these symptoms. Heavy soils could encourage root rot, the tree may be affected by a disease or insect attack, or soil pH may be too high or low for most nutrients to be available for absorption by plant roots. It is worth adjusting cultural conditions to make sure the symptoms are due to lack of nutrients. One way to do this is to dig in soil amendments to improve drainage and soil fertility.  To help ensure that your tree gets the best care possible, contact Frontier Tree’s experts today.

Common Nutrients Needed by Plants:

Plants need macronutrients such as nitrogen, phosphorus, and potassium in large amounts. The additional nutrients calcium, magnesium, and sulfur are also needed by plants in relatively large amounts. Micronutrients are also essential to plant health and vitality. These include zinc, iron, manganese, copper, molybdenum, boron, and chlorine.

Fertilizer Applications

Once our tree care experts have determined that a tree is lacking in nutrients, they can choose a general fertilizer or a specific fertilizer containing the deficient nutrient. Fertilizers are generally applied to the soil in the feeder root zone – the area below the perimeter of the tree canopy. This can be in the form of granular fertilizer dug in or liquid fertilizer drenching the soil. In certain cases, foliar feeding can be more effective in ensuring nutrient uptake. This is when the liquid fertilizer is applied directly to the leaves.

Whatever type of tree fertilization service your tree needs, you can rely on Frontier Tree Service to give your tree the very best of care.
