My name is Ryan and I just recently became interested in growing Cacti. This weekend I bought a Parodia Magnifica and a Mammillaria Pilcayensis and have a few questions about soil to grow them in.
Right now I'm thinking about using a 50/50 mix of Miracle-Grow Cacti Soil and Perlite.
My questions are
1) Should I change the ratio & add more perlite?
2) Should I add another ingredient like topsoil or regular potting soil & use less Miracle-Grow?
3) What other advice do you have for a good Cacti soil?
Like I said, I'm new to all of this and any advice on general care for my two cacti would also be appreciated. Thanks!
