Hi,
Where are the roots generated ?
a too small of a pot ? moss ? perlite ? Hard to plant without damaging them ...
A 2liters / .5gal pot ? If so I wait for the roots to hold the whole dirt, and then I plant it in the dirt (unless I want to mess with it in a pot, and the tree stays in the pot :) longer )
This time of the year with normal cuttings, I simply put them in the dirt and water to keep the dirt a bit humid - not drowning them, not desiccating them .
I did it last year with 4 found cuttings (owner threw trimmings to the public walkway ) and they turned into small trees. Now I'm hoping to see fruits from them ... that's the problem with unknown cutting ... you never know what you'll get ... But they were damn cheap ...
Every now and then, I laugh and scream at those trees ... DON'T YOU BE BTs !!!! As I already have one big BT (store bought ).
