Tree Fertilization 101: When, Why, and How to Feed Your Trees
Healthy trees don’t just happen—they’re nurtured through consistent care, strategic pruning, and well-timed feeding. In the diverse landscapes of Bluffton, Hilton Head Island, Savannah, and the surrounding Lowcountry, tree fertilization plays a key role in keeping trees strong, vibrant, and resilient.
At Kolcun Tree Care, we’ve spent over 20 years providing expert, science-based tree care. Our ISA-certified arborists understand the local soils, the challenges of our coastal environment, and how to customize care for each species—whether you’re managing a heritage oak in your backyard or a row of ornamental trees on a commercial property.
If you’ve ever wondered when or how to fertilize your trees—or if fertilization is even necessary—this guide breaks it all down.
Why Fertilize Your Trees?
Unlike trees in natural forests, the ones in our yards and commercial landscapes often grow in compacted, nutrient-poor soil. Mulch, grass, and routine maintenance can limit the organic matter they’d normally rely on. That’s where fertilization comes in.
Benefits of Tree Fertilization:
- Improves root development and structure
- Encourages fuller canopies and vibrant foliage
- Boosts resistance to insects and diseases
- Strengthens recovery from pruning or storm damage
- Enhances overall longevity and tree health
By restoring essential nutrients like nitrogen, phosphorus, and potassium, fertilization allows your trees to thrive—not just survive.
When Is the Best Time to Fertilize?
Timing is everything. Fertilizing at the right time ensures your trees absorb the nutrients when they need them most.
General Guidelines for Fertilization:
- Late Winter to Early Spring: Ideal for stimulating new growth as trees come out of dormancy.
- Fall: Helps strengthen roots ahead of winter and supports next year’s growth cycle.
- After Tree Pruning or Stress Events: A great time to support recovery, especially after trimming, transplanting, or drought.
In our warm Lowcountry climate, some evergreens and native species may also benefit from light feeding during mid-summer—but only with the guidance of an experienced arborist.
How Does Tree Fertilization Work?
Tree fertilization isn't one-size-fits-all. At Kolcun Tree Care, we use a targeted approach based on the tree species, soil conditions, and your landscape goals.
Our Fertilization Process Includes:
- On-site Evaluation: An ISA-certified arborist assesses your tree’s health and soil quality.
- Custom Blends: We select or create a fertilizer mix tailored to your tree’s needs.
- Deep Root Feeding: Nutrients are injected directly into the root zone for faster absorption.
- Seasonal Scheduling: We recommend the best times for application to maximize effectiveness.
This professional approach ensures that you’re not just dumping fertilizer on the ground—you’re feeding your trees in a way that makes a lasting difference.
Tree Fertilization for Residential & Commercial Properties
Fertilization is just as important for a single shade tree as it is for an entire commercial property lined with live oaks, palms, or maples.
Residential Benefits:
- Healthier, safer trees close to your home
- Enhanced curb appeal and shade coverage
- Improved recovery from storm damage or drought
Commercial Property Benefits:
- Uniform tree growth for visual consistency
- Lower maintenance and long-term cost savings
- Proactive protection from pests and disease
Whether it’s a resort on Hilton Head Island or a historic home in Savannah, fertilization protects your investment—and your landscape.
The Link Between Fertilization and Overall Tree Health
Fertilization is a cornerstone of comprehensive tree health care. When paired with tree trimming, tree pruning, and proper watering, it creates a full-circle approach to tree vitality.
Plus, healthy trees are better equipped to resist pests, tolerate storms, and avoid premature decay—which means fewer surprises like sudden limb failures or the need for emergency tree removal.
At Kolcun Tree Care, we’re big believers in prevention. A small investment in the right nutrients today can help you avoid costly tree removal, stump grinding, or property damage down the road.
Expert Tips for Tree Owners in the Lowcountry
Here are a few ways you can support fertilization and overall tree health:
- Mulch properly: Keep mulch 2–3 inches away from the trunk and avoid piling it too high.
- Water deeply: Especially during dry spells, water trees at the root zone—not just surface-level.
- Inspect regularly: Watch for thinning canopies, yellowing leaves, or signs of insect activity.
- Schedule annual checkups: A certified arborist can detect issues early and recommend timely care.
