I have two pots of small Hindu Rope cuttings. I have 2 more cuttings on the way. The ones I have, One is larger than the other and is sort of heavy.

My question is, when I receive the other 2 hoya plants I want to plant all 4 in one pot. My goal is to create a lush Hindu plant that I can hang from the ceiling.

How would you plant in a new pot, the heavy, long hoya so it doesn't come out of the soil due to the weight - weight it down with a pebble?
