Hi,

Why not make Your own soil ?

Here's a simple but good soil recipe
for ficus,
composed with 3 equal volume parts:

1/3 Lava grit or crushed granite (3-5 mm granules)
1/3 Akadama
1/3 Oak (or beech) leaf mulch or decomposed bark

Sieve to remove dust and lumps
and per liter of this mix,

add 1 teaspoon of blood meal and
add 1 tablespoon of bone/hoof meal

That'll work greatly,
and for a period of about 1 year,
no additional fertilisations will be needed.
