Call Licensed Arborists for Pruning Baltimore Trees and Shrubs

Pruning goes hand in hand with nutrition; proper pruning from the start of a tree or shrub’s life can prevent structural problems later. You may prune trees or shrubs for many reasons, but you should always count on licensed arborists to perform this task. 

  • Pruning for Safety: Removing dead or damaged limbs 
  • Pruning for Appearance: Create topiaries and other landscape features, and remove suckers, water sprouts, and unwanted branches. Pruning also manages the size of plants.
  • Pruning to Promote Health: Pruning can prevent further diseases or damage to a tree from animals, insects, storms, and more. 
  • Pruning for Maintenance: Pruning can help promote flower and fruit development.

We recommend pruning deciduous trees and shrubs before bud break or new growth arrives in late winter or early spring. For spring bloom plants, pruning is best after blooming in late spring or early summer. However, there is never an inappropriate time to prune damaged or diseased limbs from your Baltimore trees. 

Deep Root Tree Fertilization for Long-Term Care

Deep root tree fertilization should be performed by Baltimore licensed arborists you can trust. At Scientific Plant Service, we recommend this service for both healthy and weak, defoliated trees. Fertilization is crucial preventative care, as healthy trees can better fight off diseases and pests. The best time for deep-root fertilization is in the fall. This treatment includes our custom blend

  • Flowable sulfur neutralizes soil conditions and moves nutrients
  • 12-24-24 fertilizer contains slow-release Nitrogen from Nutralene and Humates
  • Natural Mycorrhizae enhance root growth development and function
  • Chelated Iron with Manganese and Nitrogen 

Bi-annual treatments can keep your trees healthy and help you save money on disease and pest treatments.
