Put some wood glue and then use tape , like gurilla tape and tape it ater the glue is dried. I’ve had plants break in half and doing this even with just the tape saved the plant. another thing is knowing the wind and storms and weight of plant will cause issues so doing preventive support is key. i suggest making a bamboo support , so many times have I neglected those supports and whatcha know I fucked up but it also made me learn it’s def necessary For successful harvest .
