During this period of increased rainfall, trees and shrubs absorb nutrients more effectively. Summer and winter are not optimum times to fertilize.
     A layer of compost around trees acts as a fertilizer. Like mulch, it helps the ground hold moisture and maintain moderate temperatures. Construction projects may alter the soil by compaction adding pollutants and rubble to it. Without the balanced natural environment, even vigorous specimens may have some trouble. Because a plant's well-being depends on its ability to grow, the health of the root system is crucial. Roots must keep drawing sufficient nutrients and water to sustain growth. But as they continue to grow, at some point they'll run into restrictions such as paving, structures, rocks, rubble, roots of other plants, and hard, compacted soil. Under such conditions they may not be able to absorb nutrients and water as easily as before. The results: less new growth, pale color, and damage due to insect attacks and disease. To overcome these growth inhibitors, trees and shrubs need good care and maintenance.
      Knowing when to fertilize is vital to top quality plant care. It's important to fertilize plants at or during a certain time so the tissues of the new growth will toughen sufficiently to weather the first freezes. Without this 'hardening off' and easing into dormancy, the plant can be severely damaged by winter stress. Proper timing will help you promote dormancy early enough to prevent such damage.
      Fertilization keeps trees and shrubs from falling victim to health problems. Resilient limbs and general vigor make them sturdy enough to weather storms and extreme temperatures. And the healthier they are, the more beautiful they look. Another benefit of regular fertilizing: it cuts costs. Repair work and special treatments are very expensive, especially compared to the costs of fertilizer.
      There are 3 ways to fertilize trees drive tree spikes into the ground around the drip line, punch holes with a steel rod and fill the holes to 2 inches below the turf with North Haven Gardens 6-3-0 fertilizer or use deep water feeding systems like the Ross Root Feeder.
