Sago palm

Question

My sago palm lives out door in frost free Southern Spain, however it only has one tier of leaf growth, whereas others I have seen nearby has several layers of leaf growth, why is this?

Answer 1

Sago palms are very slow growing, so it can take years to produce that second tier of leaves. Eventually a ring of new leaves will appear in the center of the plant.
