I do, and here's how I do it. I take the old potting soil, put it in a 3 gallon pot, and pour a kettle of boiling water through to kill it, then I mix it half and half with new potting soil. Things grow very well in this, and I've never had any root rot problems from the old soil.
Didymo (Didymosphenia geminata), also known as rock snot, is a non-native invasive microscopic algae (diatom) that can produce large amounts of stalk material to form thick brown mats on stream bottoms.
JorÅgumo (Japanese Kanji: çµ¡æ°å©¦, Hiragana: ãããããã) is a type of YÅkai, a creature, ghost or goblin of Japanese folklore. According to some stories, a JorÅgumo is a spider that can change its appearance into that of a seductive woman.In Japanese Kanji, JorÅgumo is written as  çµ¡æ°å©¦  (literally meaning binding bride) or  å¥³éèè  (literally meaning whore spider).JorÅgumo can also refer to some species of spiders, but in casual use it can refer to the Nephila and Argiope spiders.Japanese-speaking entomologists use the katakana form of JorÅgumo (ã¸ã§ã­ã¦ã°ã¢) to refer, exclusively, to the spider species Nephila clavata. In Digimon Adventure 02, one of the antagonists, Arukenimon (or Arachnemon in the Japanese version), is based loosely off of the JorÅgumo. 2  She shape-shifts between a normal, human-looking woman and a spider-woman.
