Rossioglossum with yellow leaves...sad :(

[annierj]

I have been nursing along a rossioglossum grande for the last couple of years....no sign of a bloom but the bulbs were developing nicely and multiplying. Leaves a healthy shade of green..However, over the last fortnight, the leaves are turning yellow and dropping off. I don't know why. Haven't done anything different. It is under a slatted balcony, on the west side of my house. Have had some accumulated rain (4 inches a week ago) but have been watering to combat the heat of the last month. Too much water? Not enough? Any help would be appreciated...

It appeared to try and throw off a spike of sorts but it never fully developed and then almost molded...but did so over a couple of days. It is mushy to the touch and looks delightfully nasty.

Any clues?

And, as a follow up, where do I go from here?

Thanks.
