Hi,
for repotting and above all to preserve the plant and my skin, I did this: from a Brico shop I bought corrugated cardboard with which I wrapped the plant by making many layers and keeping them firm and compressed with cloth tape. After this first step, I then wrapped the plant with thick, stiff cardboard and held everything together with duct tape. When all the thorns were safe, I created a mountain of soil on the floor with the help of two pockets of soil and placed the plant on its side on top of the soil. So I took off the old pot and removed the old soil, I put in the new pot, the terracotta and some soil, and getting help because this operation is impossible on its own, we raised, as if it were a lever, the plant and the his pot in an upright position, this was the most difficult moment, I believe that only the plant weighs more than 100 kg, afterwards everything was easier ...... This will surely be the last repotting ...
Sorry, I used translate ...
