So one month later and this plant is on its deathbed!

After a few weeks, a leaf yellowed and dropped off, while the root system largely died off. Over the course of the following weeks in a humidity chamber (with regular airing + a heatmat), after a promising first few weeks of leaf growth, the plant then was struck by a secondary localized fungal infection (spots + wrinkling), and then the final mature leaf yellowed and also dropped off despite treatment.

This leaf yellowing is much faster than I have experienced with some of my other phals (some of whom hold onto their leaves even if they're severely dehydrated/stressed), and it seems like gigantea quickly spirals if the root system is lost.

At this point, there is only the small newest leaf + the stem remaining + the root wires, I'm not sure how this one can be recovered. Perhaps this one will end up in the bin, unfortunately.



Lesson learnt- Phal gigantea has a low stress tolerance, and I should not pick one up that's 1.) Barerooted, and 2.) Neglected! A shame too, since this one seemed like an interesting variety.

Phals hate cold, wet roots. Phal gigantea is a seriously “hot” grower among phals.

You have kept it entirely too cold. The evaporative cooling from the moist LECA in your dry, air conditioned environment chilled the roots even more.

It was on a heat mat, but point taken.

I will try again next time with another approach (and a healthier plant), if the opportunity presents itself once more.

The heat mat likely helped a bit, but the entire plant prefers warmth, and apparently more light than other phals.
