A Season-by-Season Tree Maintenance Calendar

Ohio's four distinct seasons each ask something different of the trees on your property. Here's what to plan for throughout the year in the Miami Valley.

❄️ Winter (Dec–Feb)

  • Best window for structural pruning — trees are dormant, easier to see, and disease spreads slower in cold weather
  • Remove dead or damaged limbs before ice and snow load adds weight
  • Check for winter storm damage after ice events
  • Avoid heavy pruning on spring-flowering trees now — wait until right after they bloom

🌱 Spring (Mar–May)

  • Inspect for winter damage as buds break — dead wood becomes obvious once live branches leaf out
  • Watch for early pest and disease signs, including Emerald Ash Borer exit holes on ash trees
  • Apply a fresh 2–4" mulch ring, kept a few inches back from the trunk
  • Plant new trees now, while soil is workable and roots have the full growing season to establish

☀️ Summer (Jun–Aug)

  • Water young or newly planted trees deeply once or twice a week during dry stretches
  • Only light, corrective pruning — remove dead/damaged wood, save major structural cuts for dormant season
  • Watch for wilting, early leaf drop, or scorched leaf edges, which often signal drought stress
  • Keep an eye on trees after summer thunderstorms for hidden cracks or root movement

🍂 Fall (Sep–Nov)

  • Good season for planting — cooler air and still-warm soil help roots establish before winter
  • Clear fallen leaves and debris from around the base to reduce fungal and pest habitat
  • Have any risk-checklist trees assessed before winter storms arrive
  • Reduce watering as trees head into dormancy, but don't let the soil go bone-dry before the ground freezes
