Advanced Techniques In Rescuing A Dying Blue Spruce

Saving a dying blue spruce can be a daunting task, but with advanced techniques, it is possible to bring it back to life. In this post, we will explore some of the best methods to rescue your blue spruce. Let’s begin with grafting and reversing girdling.

Grafting And Reversing Girdling

  • Grafting is a technique where you join two different plants to form a new one. In the case of a dying blue spruce, you can graft a healthy branch onto the damaged one.
  • To do this, cut a small branch from a healthy blue spruce of similar size and diameter. Remove all the needles except for the top ones.
  • Cut a small section of bark from the damaged branch, creating a small notch.
  • Insert the healthy branch into the notch and secure it with a rubber band or grafting tape.
  • In addition, girdling refers to the damage caused by a tight band around the tree trunk. It can cause significant harm to the tree by affecting the flow of nutrients and water.
  • Reversing girdling involves the removal of the band or wire cutting through the bark.
  • If the damage is severe, then it is advisable to seek the help of a professional arborist.

Reversing Drought Damage With Deep Watering Techniques

  • Drought damage is a common problem for blue spruce, and it can cause them to droop, wilt or even die.
  • The best way to revive a drought-stressed blue spruce is by deep watering.
  • Deep watering involves soaking the soil around the blue spruce to a depth of 12 inches or more.
  • You can do this by trenching around the blue spruce and filling it with water.
  • Alternatively, you can use a soaker hose placed at the base of the tree and let it run for several hours.
  • Remember to avoid watering the foliage of the blue spruce as this can cause needle discoloration.

Reverse Needle Drop And Discoloration With Nutrient Amendments

  • Needle drop and discoloration are common symptoms of nutrient deficiencies.
  • Applying nutrient amendments such as organic fertilizers can help reverse these conditions.
  • Choose a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.
  • Apply the fertilizer in spring or fall when the tree is actively growing.
  • Avoid over-fertilizing, which can affect the tree’s health or cause it to attract pests and diseases.

Grafting and reversing girdling, deep watering techniques, and applying nutrient amendments are advanced techniques that can help rescue a dying blue spruce. These methods can help restore and rejuvenate your tree, but it’s always advisable to seek professional advice before attempting any corrective measures.


As you can see, saving a dying blue spruce tree is no easy feat. However, with the right knowledge and techniques, it is definitely possible to give your tree a fighting chance. Remember to assess the roots, check for pests and diseases, prune the tree regularly, ensure proper watering and fertilizing, and protect the tree from harsh weather conditions.

By following these steps, you can create a nurturing environment for your blue spruce tree to thrive in. It may take some time, effort, and patience, but the rewards of a strong, healthy tree are truly worth it.
