Dendrobium too heavy

[rthomas268]

Hi everyone,
I have an ancient dendrobium that I got from my mother who passed in 2006. I have kept it and have repotted it a few times and it has produced offspring.
The last time I potted it I placed all the plants in a rectangular planter pot. And yes they bloom every year in November thru January.
I allow the plants to grow naturally without any staking. As a result the stalks grow out and downward.
One plant has grown large, heavy stalks that this year has pulled the plant out of the planter. The two very heavy stalks have bloomed twice and different lengths along the stalk and show no signs of dying.
So I need to either replant and anchor it with wire into the bottom of the pot (like I would do for a bonsai) or go ahead and cut the stalks (they are about 3 feet long and an inch in diameter). I have never cut live stalks so need advice pronto!

Thanks,
Barbara
