Alas, not all is well at the window.
I checked on all my girls yesterday, and they seemed to be okay, but I noticed wee SOS was leaning over slightly, and some small yellow spots on a few fan leaves. I assumed she was just bending to the light, and turned her around. Checked online to see if the spots were symptoms of spider mites.
Anyway, was going to photograph her today to show her flowers. And she's now wilting seriously, and nearly fell over when moved. Propped her up with a skewer to take a proper look. Stem rot at the base, presumably root rot too. Not taking up water. Oh dear, such as a shame as she appeared to be doing well. Can't believe how quickly it spread. Looks like something has munched all around the base of the stem. I have removed her from the window sill just in case this spreads to other plants.
I'm assuming this is fatal. I would try to cut her and root her but she's in mid-flower and I have no reason to believe it would work. Will probably just chop her, dry and add to the edibles pile. Soil will get binned.
What a pity. Day 64 - RIP SOS.
