Violetta -

I looked them up and they have 56% of peat moss in their mixture. What I like to have is 33% of peat for wicks and 25% for Oyamas. So if you add 50%-75% perlite - it will be better in my opinion. You can get by with what you have till the next repotting if you let your Oyamas dry a bit before rewatering and do not fill the underpot up to the highest limit.

Good luck

Awesome, thanks Irina!

I have the same mixture in an oyama that I'm trying to grow a baby in from a leaf. Do you think that one will be okay? Or should I just scrap it and start over again with more perlite?

Violetta -

you can easily rot the leaf in Oyama pot with heavy mix.
If your leaf is in this mix but in Solo cup - it possibly will be OK, just keep it just barely moist and covered. You can always prepare another Solo cup with a lighter mix and transfer your leaf. If it is already rooted - use a fork and accurately move leaf, roots with a bit of soil to a new pot.

There is more than one way to get you baby plants from a leaf - and whatever works for you is usually very much OK.
They are pretty tough little plants and they try to propagate in all conditions.

Good luck
