Congratulations on growing and flowering your Phal to the point that it becomes a burden , Jai.
In nature they grow upside down so it would never be a problem.
I would use one of these wire products that clip onto the side of your pot, and secure the spike to that.
This particular one is for plastic pots, but they are made for clay pots as well.
Don't forget to post pictures of your blooms in our monthly what in bloom thread!
