Phal - Top heavy and unwieldy roots

[aliceinwl]

I'd wait until its done blooming unless your frustration over how unwieldy it is out ways your desire to enjoy every last flower (this has been my experience a few times). With orchids like this, I just get a bigger pot and upsize.

I admit to sometimes just including the air roots in the pot if they're part of what's making the plant unmanageable and I can do so without breaking them. I like to use a fairly open bark mix, so the air roots survive the transition fine (this may not be the case if you use a denser more moisture retentive mix).

I also cut the spikes on plants when they're part of the weight issue. I have one Phal that kept producing one flower at a time from an ever lengthening spike. After over a year of this, I couldn't keep the plant upright because of the weight of the spike. I cut the spike off despite the presence of yet another flower and bud. The plant responded by sending up two nice new spikes with over 10 flowers apiece.

It's a nice problem to have when a plant is just too happy :-)
