We had our stumps grinded last year and now it’s blended into the dirt which was a huge mistake anyway we got a small 2ft pool and now it’s near and small patch where oleander stump got grinded and there’s oleander chips. my kids have been swimming in the pool I’m just so afraid of the water getting contaminated because Of how poisonous it is and that’s the reason we got rid of them. Now I’m freaking out one leaf is lethal and there’s chips in the yard even after leaf blowing it several times throughout the year.
