Tree Health FAQs

We recommend an annual check-up for most trees, but more frequent inspections may be needed if you notice any signs of trouble.

Stress can come from various sources, including:

  • Watering issues (too much or too little), especially summer drought
  • Soil problems (compaction, poor drainage, or lack of nutrients)
  • Weather damage (storms, high winds, or extreme temperatures)
  • Mechanical damage (from lawn equipment or construction)
  • Improper pruning or planting techniques
  • Planting in conditions not suitable for the tree species

All of these stressors can make trees more susceptible to pest infestations and fungal infections.

Often, yes! The key is early detection and treatment. If you notice any unusual changes in your tree, give us a call right away.

Yes, we prioritize eco-friendly options whenever possible, balancing effective treatment with environmental responsibility.

Treatment times vary depending on the issue and method. Some injections can be done in an hour, while other treatments may require multiple visits.

Timing depends on the specific issue. Some treatments work best before problems appear, while others are applied when symptoms show up. For example, we might treat fungal leaf diseases in late spring, but wait to address other issues until we spot them.

Although there are some DIY options for small trees, many effective treatments require professional expertise and equipment. Large trees (over 12-14 inches in diameter)especially benefit from professional care. We have the right tools and know-how to treat trees safely and effectively.
