I've just got your response Ken, for which I thank you a lot. I know about cycads and love them a lot, for their history, their look and because some of them are endangered species, I used to have a Sago but it died together with all my other plants during our last moving. Now I want to re-start and this time I got something else than Sagos. I just received the package, earlier than expected. I got: Encephalartos Ituriensis, E. Concinnus, E. Manikensis and a Cycas Thouarsii (this one is not looking good, the grower just sent it to me as a bonus).
OK, so they need to be fertilized from the very beginning, when potting them today/tomorrow. Thanks for all the detailed instructions! The grower told me to add some cactus/palm mix too. Should I use 1/2 cactus/palm mix and 1/2 regular potting soil for the 1/3 part of soil? And is better to use pea-gravel or sand instead of wood chips? So I can take the pumice off the list.
Thank you again. I'm so excited!
