r/Pelargonium

Hello all! I just purchased three pelargoniums, and I am seeking some advice regarding the appropriate soil mix for them:

• P. 'Arucana'

• P. schizopetalum

• P. sidoides

Right now I am planning to do 40% Bonsai gravel mix; 40% Fox Farms Happy Frog potting mix; and 20% coarse perlite.

Thanks for your help.
