Dormant phal with odd leaf
Default Dormant phal with odd leaf

Iím Minding this phal which is over 10 years old and only bloomed once early on in that time. I have started it in kelp max and orchid food, repotted from broken down media and given it a sunny spot for the 6 months itís with me (3 months passed) a leaf fell off (wasnít too worried as yellow was from outer and it was the oldest leaf) I notice now the second small leaf is yellowing so slowly and dying too. Why the second not the bottom leaf? Roots look great on this orchid and Iím not sure why itís happening?

Phals are shade plants. They don't ever need sun shining on the leaves. If it's in large bark you may not be watering enough.

we have noticed some of our phals will drop a leaf when they are getting ready to do something else. maybe you will get lucky with some flowers!

The leaves are a very very pale yellow-ish-green which suggests that the light is at the extreme upper end of tolerability. Itís probably adding unnecessary stress to the plant. You donít want a deep forest green (not enough light) but your leaves are much lighter than is ideal.

It looks like that because of the sunlight but it only gets adequate sun and the small leaf is the only one that colour. I had trouble uploading all the pics but Iíll try again. Itís a normal colour phal apart from that leaf

It gets filtered sun and not too much. Itís getting enough water. Other leaves are fine. Just that second small leaf thatís odd.

OK, hereís my takeÖ

Sometime in the past, the plant hit a spell of ďso-soĒ care, or other issue, that led to a stunted leaf. The plant is a lot healthier now, so ďdecidedĒ to resorb the phytochemicals and ditch that leaf.

As to not blooming, my guess is that it isnít getting the required temperature profile to initiate a spike.

Such hybrid absolutely thrive in very hot, humid conditions, but they will not reliably initiate a flower spike until they experience 10-14 days of an average growing temperature about 6-9C cooler. After that, return it to the heat for best spike growth.

People frequently focus on the day/night temperature variation, but that nighttime reduction must be double those earlier figures to achieve the correct average.

I took another look and youíre right, it was the backlight that made the whole plant look very pale green. Knowing that, Iíd agree with Rayís assessment.

I have bloomed Phals in the house with rather minor temperature variation... the trick that worked for me was to increase the duration of light to 12 hours using supplemental lighting. (I used fluorescents, it was years ago, but now LEDs are available that use much less energy) So low light, but more hours might get you flowers.

There is no doubt that some phals will bloom without the relatively extreme temperature reduction, but the thing about exposing them to it is that it is a way of reliably getting them to do so.
