Crete, located about 25 miles southwest of Lincoln in Saline County, is a charming community known for Doane University and its agricultural heritage. Like communities throughout southeastern Nebraska, Crete’s alkaline soil creates widespread iron deficiency in landscape trees. Most homeowners don’t realize their pale, yellow-green trees are actually malnourished. Iron deficiency is so common in our area that customers are consistently amazed by the vibrant transformation after treatment. Yard Boss delivers professional trunk injection services that provide visible results within weeks. Trees most susceptible to iron deficienty:
Pin oaks are extremely prone to severe chlorosis in Crete’s soil and show the most dramatic improvement. River birch very commonly displays pale leaves as standard without treatment. Red oaks, silver maples, and sweet gums frequently show deficiency in our alkaline conditions. We also treat other oak species, maples, ash trees, willows, and fruit trees. However, we will not treat trees already in significant decline or otherwise unhealthy—iron deficiency is just one of many problems, and treating iron won’t save a dying tree from other causes.
Crete sits in an area with naturally alkaline soils due to limestone bedrock and our dry climate. While iron is present in the soil, it exists in ferric form (Fe3+) that tree roots cannot absorb. Trees can only use ferrous iron (Fe2+), which requires acidic conditions. This means your pin oaks, river birch, and red oaks are literally surrounded by iron but unable to access it through their roots. Our trunk injection method delivers iron directly into the tree’s vascular system, bypassing the soil chemistry problem entirely and ensuring 100% absorption.
Spring (Optimal)
April – June
Tree Activity
Peak nutrient uptake, leaves expanding, & high transpiration
Treatment Effectiveness
Excellent – Fastest visible results (2-3 weeks)
Summer
July – August
Tree Activity
Active growth and transpiration high in healthy trees
Treatment Effectiveness
Excellent – Good uptake, results visible in 3-4 weeks
Early Fall
September
Tree Activity
Trees still active, nutrient storage for winter
Treatment Effectiveness
Good – Uptake slower but effective; benefits visible next spring
Late Fall
October – November
Tree Activity
Trees preparing for dormancy, reduced activity
Treatment Effectiveness
Fair – Limited uptake; mainly benefits next year

We recommend annual trunk injection for Crete trees because our alkaline soil is a permanent condition. Each treatment provides iron for one growing season, but trees cannot store it long-term or access it from soil independently. Think of it as an annual vitamin for your tree—you get dramatic benefits when treating, but those benefits don’t last forever without continued supplementation. Spring treatment (April-June) provides optimal results with color changes visible in 2-3 weeks, though summer applications work excellently as well.

Your trees have iron deficiency because of Nebraska's alkaline soil, not because there's no iron in the soil. Here's the explanation:
How to tell if your trees are iron-deficient:
Most common on: Pin oak, river birch, red oak, silver maple—these are "acid-loving" trees that struggle in alkaline soil
Iron injection can be done anytime the tree is actively taking up nutrients, which means anytime from spring leaf emergence through early fall before dormancy.
Best Timing by Season
Our recommendation: Spring is ideal for fastest results, but summer treatment works great too. If you're noticing pale foliage in July, treat now—don't wait until next spring!
No! Trees heal from injection wounds quickly and easily. Here's why you don't need to worry:
Trees regularly survive wounds from:
Our tiny injection points are minor compared to wounds trees naturally handle. The benefit (vibrant green foliage and improved photosynthesis) greatly outweighs the minimal, temporary stress of small injection points.
Your tree will continue to struggle with iron deficiency. Here are the consequences:
Short-Term (This Season)
Long-Term (Multiple Years)
The "Opportunity Cost"
You planted this tree (or bought a property with it) because you wanted a beautiful, healthy shade tree adding value to your property. Iron deficiency means you're getting 50-70% of the tree's potential beauty and only 60-80% of its potential growth. Treatment unlocks the tree's full potential—the vibrant green color and vigorous growth you expected when planting it.
No—iron injection is an annual treatment because the underlying soil problem (alkaline pH) is permanent. Think of it like taking a daily vitamin:
Why not permanent? The alkaline soil constantly prevents root iron uptake. Annual trunk injection bypasses this problem, but only for one season. It's not that treatment wears off—it's that the tree can't get iron from soil on its own and needs the annual supplement.
If tree already has deep green foliage, it probably doesn't need iron treatment. Either:
We assess each tree individually. If foliage is already vibrant green, we'll tell you treatment isn't needed—we don't sell unnecessary services.
Young trees benefit from iron injection, but considerations:
As young trees mature and trunk diameter increases, trunk injection becomes the most effective long-term solution.
Great news—tree height doesn't matter for trunk injection! We inject at trunk at breast height (4-5 feet up), not in the canopy. Tree can be 10 feet or 100 feet tall—injection method is the same. Iron is transported throughout tree via vascular system regardless of height.
