Accidentally cracked the stem on top what to do?

@hashy, it can still stand up! At least it’s standing for now. Should I just leave it like that or put something around it?

Hello. I find if I use tape direct on the plants they often have a reaction to the adhesive which can be seen for weeks after, or I pull some of the outer layer of stock off when it is removed which leaves a mark. If I've cut or hurt my plants I put some sulphur on the wound then take some stiff cardboard and make a tube. Unroll the tube and reroll around the cut or break. Put as much tape around the cardboard as you want. Hope that helps. Chuck.
