What is the best way to “accelerate” the decay of several hardwood tree stumps?
What is the best way to “accelerate” the decay of several hardwood tree stumps in our heavily wooded yard? We plan to drill several deep holes to allow “quicker” water/oxygen/worm/bug penetration but are there any “safer” additives that won’t have untoward ecosystem downsides? Maybe honey, for example?
Unfortunately, tree stumps just take their own sweet time decomposing. Short of grinding it, there aren’t a lot of magic removal or speeding up options–I couldn’t find any scientific studies for the effectiveness of “acceleration” products. Drilling the holes is a good idea, and you could fill those holes and then cover the stump with compost to boost the microorganisms working on the problem. Covering it with a tarp might help promote warm, moist conditions, too, though make sure you can get some airflow up underneath to keep things healthy.
