How to kill an Oleander stump. The stump is like granite

Do NOT BURN IT. Oleanders are poisonous and igniting that will not end well for anyone. Idiots.

Depending on stump size and location/accessibility my husbands GO TO is the truck. Heavy chain and stumps gone in no time.

I had this problem and I tried two methods - on the same stump. Copper nails and Epsom salts and I waited for ages. https://theyardandgarden.com/how-to-kill-a-tree-stump/ it takes about two months and the wood goes spongy and breaks up.

My brother-in-law then successfully killed a tree stump in his yard by burning it. This was very effective but a bit too ferocious for me to attempt. Plus I see above its not recommended for your species lol
