A big wooden stick picked up by the roadside, its ends chopped off and planted in a pot, surprisingly grew full of green leaves

We often see big wooden sticks next to trash bins, and on closer look they turn out to be the trunks of money trees (Pachira aquatica). These are mostly from offices or newly opened stores; those money trees for grand openings usually have plastic foam padding at the bottom of the pot, so they basically don't live long, and die in about one or two months! But it doesn't matter. If others throw them away, pick them up and treat them like this, and they become a good money tree again!
1. Check the root condition. Most of the discarded wooden sticks have rotten roots, so the first step after bringing them home is to deal with the roots. Also check whether any other parts are rotting and clean them all up.
2. First wash the roots clean with water, and prepare sterilized soil, a sharp knife, and rooting hormone.
3. Clean off all the roots; the principle is to leave none, shave them clean, and pure white is best. After shaving clean, soak the roots in potassium permanganate solution for about half an hour, then rinse clean with water. Then soak in rooting powder for half an hour to speed up rooting.
4. After soaking, trim a bit more as appropriate, and cut off all the branches at the top. If there were none to begin with, that saves trouble!
Once trimmed, it can be potted up!
5. During the month after planting, pay attention to controlling water appropriately, do not expose it to strong sun, keep it in a shady place for care, and do not spray water directly on the trunk. Once the roots have grown well, the small buds on top will also grow out!
