When a tree is removed, the remaining stump creates problems. Leaving it in place can be a tripping hazard or attract wood-boring insects like termites and carpenter ants that might spread to structures or other healthy trees. Certain tree species may also sprout new growth, requiring repeated cutting. Addressing the stump is necessary for safety and landscape maintenance. Solutions generally fall into three categories: mechanical removal, methods that accelerate biological breakdown, or repurposing the remnant into the garden design.
Professional Stump Grinding
Professional stump grinding offers the most immediate and efficient solution for removing a tree remnant. This process utilizes a specialized machine equipped with a heavy, rotating cutting wheel that systematically chips the wood into small pieces, similar to mulch. The machine typically grinds the stump down to a depth of 6 to 12 inches below the surrounding grade, which is sufficient for planting sod or grass seed. If planting a new tree in the exact location, a deeper grind, potentially up to 36 inches, may be necessary to remove competing root fragments. The cost is primarily determined by the stump’s diameter (many contractors charge between $2 and $5 per diameter inch) and the wood type, as dense hardwoods take longer to grind than softer woods. The resulting mixture of wood chips and soil is left behind and can be used as mulch or removed for an additional cleanup fee.
Accelerating Natural Decay
Accelerating natural decay is a budget-friendly, hands-off option, though it requires patience. This technique encourages microorganisms that break down wood fiber to work at an increased rate. The process begins by drilling a series of deep, wide holes into the top surface of the stump. These holes are filled with a high-nitrogen substance, which acts as a nutrient source for wood-rotting fungi and bacteria. Commercially available stump remover products often contain potassium nitrate, which accelerates decomposition; alternatives include Epsom salt, manure, or high-nitrogen fertilizer. The stump must be kept consistently moist to support microbial activity; covering it with a plastic tarp helps retain warmth and moisture. Even with accelerants, the timeline for manual removal can range from several months to a year or more, depending on the wood species and size.
Manual Digging and Root Removal
Manual removal is a physical method best suited for smaller stumps or when machinery access is restricted, requiring simple tools and substantial effort. The process starts by using a shovel to excavate the soil around the base of the stump to expose the root collar and the main lateral roots. Tools such as a mattock are used to loosen the soil and slice through the roots. Pruning saws or a reciprocating saw can cleanly sever the larger roots extending away from the stump. Once the majority of the lateral roots are cut, a digging bar or pry bar can be used to leverage the main root ball out of the ground.
Repurposing the Stump
If immediate removal is not desired, the stump can be transformed into an interesting and functional landscape feature. One common idea is to hollow out the center to create a unique planter for flowers, herbs, or succulents. It is advisable to drill small drainage holes into the bottom of the hollowed area to prevent water accumulation and accelerated decay. A short, level stump can also be sanded smooth and sealed with polyurethane or a wood preserver to serve as a rustic side table or seating area. Alternatively, the flat surface can act as a pedestal for a birdbath basin or a piece of yard art. Applying several coats of an outdoor wood sealant is recommended to maintain the stump’s appearance and slow the natural decay process.
