Thanks for your comments, I started to use 100 % perlite for my leafcuttings and the results are good. You never have the problem of overwatering!! The first shoots came up after 6 weeks and depends a lot of the species. For my sansevieria plants I use a mix of soil with fine volcanic stones. I water my sansevierias in the summer regular which gives a good growth. In winter I water every 2 weeks depending the wheater. We have a nice subtropical climat, high sunradiation levels, min temp in winter 12 ºC and min temp in summer 18ºC.
Hi! I am wondering what kind of medium you are using for your leaf-cuttings. From the photos, they look like perlite (coarse grade). I also would like to know what is your medium for growing sansevierias based on your local conditions. I have a good collections from different parts of the world. I just would like to compare with you.
