Help me diagnose Mircale Fruit problem
I planted a Synsepalum dulcificum (mircale fruit) from seed some years ago.
It's been doing ok even if every winter some leaves fall and the growth stop until summer.
Although this years, new leaves stay small and really pale while spot of rust/discoloration is appearing on old leaves.
Soil : 50% peat moss / 50% perlite
Water : I let tap water sit for 24H
Fertilizer : none
I'll be happy to provide any more information if needed.
Any help is really appreciated.
