Why would you use rooting hormone on a seadling?


My hand was itching to try the cutting technique out of JBP seedlings (in case you missed it in the thread, this is the procedure: bonsaitonight.com/2011/07/01/how-to-crea...japanese-black-pine/).
I have very much appreciated people’s advice to avoid it, but I’ve felt like I can pull it off with sufficient attempts.. and it worked :D

So, autumn is here: temperatures dropped to 1 (night) -> 13 (day) degrees Celsius + wind and rain (less sun).
All 3 of my remaining JBP seem to be drying/withering out the bottom needles (see attached photos).
I am watering them once a day, with a well drained soil.
Am I doing something wrong?

Looks like they are still indoors? Jbp is a temperate species and must be outdoors.

They are outside, 24/7.

Update: the needless turned from green to purple (lovely color to be honest)! Also, 1 of 3 JBP has much longer needles (the one grown naturally, the other 2 have been previously turned cuttings + root hormone).

I’ve stopped fertilisation in September according to the Bonsai fertiliser bottle (NPK 4-3-9).
And I have been watering once a day, in the morning.

How do you guys proceed with watering and fertilisation during winter?

Water and fertilising stops completely in winter. Your soil looks really wet tbh
Concerning your fertiliser: there is absolutely no need to use bonsai fertiliser.Any regular all purpose fertiliser will do. Anything labeled "bonsai" is automatically more expensive. You have saplings, nothing to do with bonsai for the first 10-15 years anyway.
