Factors include the size of the stump, how many surface roots, how tall the stump “hump” is sticking out of the ground, the type of wood, the ease of access to the stump and the number of stumps.
Most chips can be used for mulch, or taken to the municipalities compost pile.
I grind 6” below grade, grind exposed surface roots, and rake the debris back into a pile where the stump was. My grinder can go up to 21” deep, if necessary. For example, when installing concrete I would grind 12” below grade.
The machines are turf friendly, similar to a riding lawn mower. You will see tracks where the grass is matted down, but there is normally no damage to the lawn, unless adverse conditions exist.
No, you don’t need to be home. I generally will contact you two days before I plan to grind the stumps, and then again when I’m on my way to the job.
As long as I can get to the stump, it can be ground.
I recommend removing the chips, backfilling with clean dirt, compact the soil, plant grass seed and cover with straw.
I will always have a conversation with the customer about underground utilities. In cases where there is a potential conflict with underground utilities, Stump Grinding by Mike, LLC will contact diggers hotline, which takes three business days to get marked.
Lamp posts, service to a detached garage or shed, sprinkler systems, propane lines, etc., are not marked by Diggers Hotline. The customer can call Private Lines to have electrical lines marked or their specific provider for propane or underground sprinkler systems.
I do not, however, I work with a partner landscape company that can provide that service.
