The Pachypodium Rosulatum seedlings now had two growing seasons and I could not be more pleased with how they are growing. This is how they looked in March, notice how there is not really that much difference between the one grown inside (pic 1) and the one grown outside during its first summer (pic 2).
Look at the difference now! I still kept one outside and one inside but what probably also helped is that the one grown outside got a bigger pot. The one kept inside has grown but nothing compared to the big one.
Seedling one has put out a good amount of leaves but really the growth of the caudex has been disappointing. This one is going in a bigger pot in spring and will be spending its time outside just like its big brother.
