The Siam Queen gave my herb garden some kind of fungus/mold/whatnot. It's black and it's icky, and it literally happened overnight. WHAM! The black stuff goes on the leaves, and it also seems to eat away at the stems from the roots up so that the whole plant dies. I had to eradicate my basil, my summer savory and my english thyme. So far, knocking on wood all the while, my pineapple sage and grapefruit mint that were neighbours with the basil got the black stuff on the leaves but I think I managed to save the plants, and I've removed all the affected leaves. My variagated thyme and the sweet marjoram that were neighbours with the english thyme also seem unaffected. I heavily pruned the lemon balm that shared pot with the summer savory (RIP). I'm very tired right now. I guess this is the drawback of anthropomorphizing your garden and talking to your plants and all. Blech. And I can't really place the whole blame on the Siam Queen: I think the mold/fungus/whatsit came here from it, yes, but I think it only managed to explode like it did because I was overzealous about the oil-soap-water solution spray. I've never been more grateful for the absolute uber-hardiness of rosemary and penny royal mint before. They're both just growing away, completely without even a blink in the direction of their missing and butchered neighbours. The rosemary is even starting to go into bloom.. Between that and the fact that I'm gonna go buy more herbs now, I feel a bit better.
