Spring Tree Care Checklist

After a long Wyoming winter, your trees are waking up and getting ready to grow. What happens right now sets the tone for the entire season.

Our soils are often dry and compacted, and insect and disease pressure can show up fast once temperatures rise. A simple spring checklist can go a long way in keeping your trees healthy and resilient.

Spring Tree Care Checklist

1. Fertilization 

Spring is the time to support your trees from the ground up.

• Nutrients are placed directly into the root zone where trees can actually use them
• Helps improve leaf color, growth, and overall vigor
• Supports long-term health without forcing unnatural growth
• Especially important in Wyoming’s dry, compacted soils

Think of this as setting a strong foundation for the entire season.

2. Disease Suppression 

Many tree diseases start early, even before you see symptoms.

• Preventative treatments help suppress common leaf diseases and stress-related issues
• Targets problems like leaf spot, blight, and needle diseases
• Protects new growth during the most vulnerable time of year

Once disease shows up, it’s harder to control. Spring is about staying ahead of it.

3. Insect Prevention

Surface-Feeding Insects

• Aphids
• Mites
• Scale

These insects feed on leaves and needles, causing stress, discoloration, and reduced vigor if left untreated.

4. Priority Trees to Protect

If you have any of the following trees on your property, this is one of the most important areas to stay ahead of:

• Birch
• Ash
• Pines
• Spruce

Insects attack from the inside out, disrupting the tree’s ability to move water and nutrients. By the time visible decline shows up, damage is often already advanced.

For these tree types, preventative protection isn’t optional, it’s one of the best ways to preserve their health and avoid costly loss.

Treatment options may include:

• Trunk sprays for surface protection
• Bark applications for penetrating defense
• Systemic treatments or injections for season-long protection

Preventative treatments are far more effective than waiting until damage is done.

Final Thought

Spring isn’t about reacting, it’s about getting ahead.

A simple plan that includes fertilization, disease suppression, and insect prevention can make the difference between a stressed tree and a thriving one all season long.
