Nature doesn’t use a calendar, so neither do we. 🌡️🌳
A common question we get this time of year is: "Is it too late to prune my Oaks?"
While many people aim for an April 1st cutoff, at LundinTree, we track Growing Degree Days (GDD).
What’s a Degree Day? It’s a way to measure heat accumulation. Insects—like the beetles that spread the devastating Oak Wilt fungus—emerge based on how warm it’s been, not what the date is. Once we hit 231 GDD, the risk of infection sky-rockets.
Because this spring has been a wave of warm and cold days, we are monitoring the data daily to ensure we’re protecting your trees, not just checking off a schedule.
If you have an Oak that needs attention, the "safe window" is closing fast. Let’s get it done before the beetles wake up.
