@Heruga, for right now,
my advice is to give the poor tree a minute to catch its breath. It has been taken from a pot in which it was very comfortable, had its roots slashed
, and been planted in foreign soil.
Any plant which is transplanted goes through an adjustment period, and it might look bad for a couple weeks. It is in shock - and they
ALL do that, whether you did it right or not. . . You can water it, you can feed it nutrients, you can baby-talk it, but right now, it just needs a couple weeks to get over what has happened to it.
As long as you have watered it thoroughly, MY advice would be to ignore it completely for at least 2 weeks. Maybe 4. .. .. It needs time.
Sorry, but you seem to go crashing in where angels fear to tread. Be patient. Do not try to fix it so much that you wind up breaking it. If you are not
absolutely sure what the problem is, don't try to fix it!!
As for right now, you have done what you can. Give it at least 3 weeks, Then, if all is not well, bump this thread, and ask for advice.
