would appreciate advice on the way to remove tree stumps from the
garden instead of having to dig them out or have stump grinding
done. I believe there is something that you can pour into or over
the stump and it will eventually "break down" in the ground.
a tree is cut down, the roots will eventually stop growing. If left
alone, the natural process of decay will set in, helped along by
natural fungus and bacteria. Depending on the size of the tree stump,
the species of tree and soil conditions, this can take from one
year to several years.
To accelerate the natural
decay process, cover the stump with soil and compost to encourage
decay fungus. Organic matter breaks down faster in a moist environment,
so keep the soil damp. Add nitrogen fertiliser to encourage decay
the richer the soil, the better.
You can cover the soil
with grass or a ground cover, and if happy, you can leave it at
that. Otherwise, check the stump's progress in about six months
time. Eventually, when rotted through, the stump should come apart
easily enough with a few knocks with a hammer.
You can also drill holes
into the stump and poor in Round Up. Make sure you plug up the holes.
Woody Weedkiller can also be painted onto the entire stump. These
chemicals kill the stump quicker than if left to die naturally
thus the rotting process can begin sooner. They don't actually assist
in the decaying process, since wood decay is a natural process requiring
time, bacteria and fungi.
