A tree is being cut down in front of a house in a residential neighborhood.

Trees are a vital part of the environment, adding beauty and value to our surroundings. Proper tree maintenance is essential for their health and longevity. At Castellanos Tree Services, we provide expert tree care in the greater Fresno area. Here are answers to some of the most frequently asked questions about tree maintenance.


How often should I prune my trees?

Pruning frequency depends on the tree species, its growth rate, and the purpose of pruning. In general, most trees benefit from a thorough pruning every few years. Young trees may require more frequent pruning to establish a strong structure, while mature trees may only need occasional trimming to remove dead or hazardous branches.


When is the best time to prune trees?

The best time to prune most trees is during their dormant season, usually in late winter or early spring before new growth begins. This reduces stress on the tree and minimizes the risk of pest infestations or diseases. However, some flowering trees should be pruned right after they bloom to avoid cutting off next year’s flowers.


How do I know if my tree is unhealthy?

Common signs of an unhealthy tree include:

  • Discolored, wilted, or dead leaves.
  • Cracks or cavities in the trunk.
  • Dead or dangling branches.
  • Fungal growth, such as mushrooms, at the base of the tree.
  • Premature leaf drop or sparse foliage

If you notice these signs, consult a certified arborist for an evaluation.


How can I protect my trees during construction or landscaping projects?

Construction projects can stress or damage trees. To protect them:

  • Install a protective barrier around the tree's drip line.
  • Avoid cutting through roots or compacting the soil.
  • Consult an arborist to assess risks and recommend protective measures.


When should I remove a tree?

A tree should be removed if it:

  • Is dead or dying.
  • Poses a safety hazard, such as leaning precariously.
  • Has significant root damage.
  • Is diseased or infested beyond recovery


Always consult a professional to confirm removal is necessary.


Why should I hire a professional arborist?

Arborists are trained in tree care and maintenance, ensuring your trees receive proper care. They can safely perform tasks like pruning, diagnosing issues, and removing trees if needed. Attempting these tasks without expertise can harm the tree or create safety risks.

Can You Save a Dying Tree?

by Castellanos Tree Services • 9 December 2024
When a tree shows signs of poor health, many property owners wonder if it can be saved. At Castellanos Tree Services in Fresno, we often get questions about whether dying trees can recover. The answer depends on the tree's condition and the underlying issues causing its decline. Here’s what you need to know. Identify the Cause of the Problem The first step in saving a dying tree is to determine what’s wrong. Common issues include pests, diseases, nutrient deficiencies, overwatering, or physical damage. In Fresno, trees often face challenges like aphid infestations, root rot, and drought stress. Look for warning signs such as yellowing leaves, dead branches, fungal growth, or bark damage. An ISA-certified arborist, like those at Castellanos Tree Services, can assess the tree’s condition and identify the problem. Provide Proper Care Once the issue is identified, targeted care can help revive the tree. For example: If pests are the problem, treatments like insecticides or natural predators can be applied. Diseases may require pruning infected branches and applying fungicides. Nutrient deficiencies can be addressed with specialized fertilizers. For drought-stressed trees, deep watering and mulching can improve hydration. Timing is critical. Acting quickly when you notice issues gives your tree the best chance of recovery. Know When Removal is Necessary Unfortunately, not all trees can be saved. If a tree is too far gone—such as when more than half its canopy is dead or it poses a safety hazard—it may need to be removed. At Castellanos Tree Services, we always prioritize saving trees when possible, but we’ll advise tree removal in Fresno when it’s the safest and most responsible choice. The best way to keep trees healthy is to prevent problems before they start. Regular tree trimming, seasonal pruning, and routine health assessments are key to maintaining vitality If your tree is showing signs of decline, don’t wait. Call Castellanos Tree Services at  559-202-0710  for an evaluation. With over 30 years of experience, our ISA-certified arborists can help diagnose the issue and recommend a plan to restore your tree’s health, or ensure safe removal if necessary.
