As most of you know I have been keeping aloes for a long time with very few losses . This fall I have ran into a rot problem that seems to be systematically taking down my plants . Yesterday I caught one before it was total mush so I could take some pics before it dies
I am leaning towards root rot but I have seen the occasional black shiney round marks on my plants . This seems to clear with fungal treatment. These marks are tiny and nothing that looks like a major issue . I have been resisting a mass fungicide spray because I know these chemicals are not exactly harmless to the plants they just kill the fungus and bacteria faster
I am at the point now where I feel I need to do something drastic . We have have the wettest summer in a long time here so a lot of humidity
I have not watered the plants for weeks the soil in the pics is dry and does not stick to your hand
Actions
I have made sure there is air movement. The latest plant to go was literally closest to the fan . You can feel the air pushing on you on that location
I have been keeping the plants at 10 degrees c overnight with heating
I have stopped watering early this year
I have changed a lot of topping gravel for a more porous moler clay
What to do next ?
I could treat all pot with a peroxide to kill any root level negative bacteria . Risk is I will cause rot again on plants because of the time of year
I could spray all plants with fungal treatment?
I could spray all plant surfaces with alcohol
I could of course do more than one
Anyone have any views ?
