- When is it safe to prune an oak in Rochester?
- Not April through July. Minnesota guidance is to avoid pruning or cutting oaks during that window, because fresh wounds attract the sap beetles that spread oak wilt. The risk drops after mid-July and the dormant season is safest. If a storm-damaged oak has to be cut inside the high-risk window, the wound gets sealed immediately rather than left open.
- Is emerald ash borer in Olmsted County?
- Yes. It was confirmed in Olmsted County in 2014 near the interchange of Interstate 90 and Highway 63, and found within Rochester the following year. The county has been under state and federal quarantine since, which restricts moving ash wood and hardwood firewood. Ash made up about 15 percent of the city's roughly 100,000 public trees at that point, including around 8,000 on boulevards.
- Can I take down the tree between the sidewalk and the street?
- Not on your own. Boulevard trees are city trees, and any work on one needs a boulevard tree work permit from Rochester Forestry. If the tree is hazardous, the city removes it at no cost to the resident. If it's structurally sound and you want it gone anyway, you pay for the removal, the grinding and a canopy loss fee.
- The city sent a notice about a dead tree. How long do I have?
- Twenty days from the written notice. After that the city can have the tree removed at your expense plus a $37.50 administrative fee, billed the same way as city taxes. The standard is whether the tree threatens the general public, and Rochester does not require the stump to come out afterwards.
- Why won't anyone quote a removal over the phone?
- Because trunk diameter isn't what sets the price here. Rochester sits in the Zumbro River valley and a lot of properties back onto wooded slopes where nothing on wheels gets within eighty feet of the tree. Carrying every round of a sixty-foot oak up a ravine by hand is hours of labour that a chip truck parked twenty feet away would have absorbed in minutes.
- Does the stump come out with the tree?
- Only if you ask for it. Grinding is quoted separately because the depth depends on what the ground is going to be used for. A four-inch grind with the chips mounded over the hole is a genuinely cheaper job than a twelve-inch grind backfilled with topsoil, and only one of them lets you plant there. Expect the spot to settle over the following months either way.
- What happens to the wood and the brush?
- That's a decision you make before the quote, not after the job. Brush is normally chipped and hauled, and trunk wood is cut to length and either stacked for you or taken away. Ash is the exception — Olmsted County's quarantine means it has to go somewhere that can legally accept it. If you want the wood for firewood, say so up front, because it changes what gets loaded.
