I have 7kg of Pistachio empty shells that I've collected over 3 years.
Is it a good idea to use them as drainage medium at the bottom of the pots under the soil for cactus?
Or is there any other use I'm not aware of?
-
You can use it as an aerator in the soil, like perlite.
-
Crushed? or untouched?
BTW, would it decompose after some years and cause problems for the cacti?
-
Whole would probably be best for aeration.
As for them decomposing, everything I've read says they take a very long time to decompose, even when crushed and composted. So you should be safe there.
