Is there a way to downsize a den?

[POLKA]

I wouldn't necessarily use that growth retardant -- which does what it says -- retards growth -- all growth -- roots, leaves, stems, and sometimes flowers.

I've got tall dendies -- 2 to 5 feet tall -- the typical grocery store types (dend phals) --

They like water, and fertilizer (up to 200 ppm N)

Pot them in rocks, let them dry between waterings, and stop fertilizing those that have bloomed already. They will grow slower, and shorter, but still bloom if they are old enough, and getting enough light.

Other than that, trade/sell them to someone, and take the money and buy the ones which grow shorter.

Take care, and have fun
