If you live in Central Iowa, you know how quickly the seasons can change. One week it feels like summer, and the next, we’re scraping ice off our windshields. These shifts don’t just affect us—they have a big impact on our trees, too.
From spring buds to winter snow, each season brings its own challenges. Understanding how seasonal changes affect your trees can help you keep them healthy year-round. Here’s what to look for as the weather changes in Iowa.
Spring: New Growth, New Risks
Spring is exciting for trees—buds, blossoms and fresh leaves start to appear. But, all that new growth makes trees more vulnerable. Insects wake up, fungi become active and late frosts can cause damage.
What to do: A spring tree check-up is one of the best investments you can make. Pruning, fertilization and preventive treatments protect your trees before pests or diseases get out of hand.
Summer: Heat and Storm Stress
Summers in Iowa bring high heat, humidity and sudden storms. These conditions put stress on your trees, especially during dry spells. On top of that, strong winds and lightning can cause significant damage.
What to do: Keep your trees hydrated with deep watering, especially during drought. Mulching helps retain soil moisture and reduce heat stress. Pruning weak or overextended limbs can minimize storm hazards.
Fall: Preparing for Dormancy
As leaves turn and drop, trees begin storing energy in their roots for the winter ahead. But fallen leaves can harbor diseases and untreated summer wounds can carry over into the next year.
What to do: Fall is a great time for structural pruning, disease prevention and fertilization. Cleaning up leaves also reduces the risk of fungal issues in the spring.
Winter: Cold and Quiet Challenges
While trees appear to rest in winter, the cold still poses risks. Heavy snow and ice can weigh down branches, while rapid freeze-thaw cycles can cause bark cracks.
What to do: Winter is actually one of the best times for pruning since pests and diseases are inactive. With leaves gone, it’s also easier to spot structural problems.
