What size pots to transplant liners.

[NWpalms@206]

Palms came today despite the chaos at the post office. Hoping someone has some insight on how large of pot I should put these liner sized hybrids in. Is 5 gal ok? Or 15, is bigger better? or should I stage up slower… I figure the less transplants the better on the plant, and it can go straight in the ground from 5 or 15 gal when ready maybe spring 2023.  The roots are visible and or coming out of the bottom of all 4 liners.

I put mine I got from Patrick into 3x3x14 deep pots, but one gallons should give them room to grow.

5 or 15 gallons are overkill in my opinion. I agree, I’d go into a 1 gallon size, maybe a 2. Saves you a lot of room too! I got a (JxB)xS from Patric a while back and had that thing crammed into a 2 gallon for a long time. It was much bigger than yours and was totally content.

Hmm ok... That’s good to know, Also lot more potting soil and good dirt is expensive! I’ll probably do 1 or 2 gallon. Wondering if deeper narrower pots helping encourage downward root growth first? Imagine this is good thing. Not sure if that ls the idea but seems like deeper roots would help with stability and strength as it matures. I think these things are gonna take off. I have heated lighted greenhouse so they will be cozy all winter until spring sunshine. Pretty excited for this BxPJT!

They probably would, but I wouldn’t sweat about it too much if it’s going in the ground relatively soon. I’m excited to see how the BxPJT does for you! Kinda want one now…

I know it makes sense to me, and I know deep roots hold true for deciduous trees.  But I heard Jeff Marcus say in a youtube clip that most palms' roots stay really shallow.  He was talking about how rocky their soil is so they bring in dirt and create beds that are only something like 6' deep if I remember right.  He said most palms don't need deep roots. 

I also have a poor memory so someone please correct me if I'm wrong.

Not sure on shallow roots for palms, as I've only really been focused on growing them for the last five years or so.

However in this time I've noted that regardless of the size of the container, 1 gallon to 25 gallon, the palm always seems to eventually have roots growing out the bottom.  I also know when I transplanted two Butia over the summer the roots went much deeper than my yen inch saw all blade.

I've also seen where some palms languish in too big of a pot whereas others explode, so dunno.

Well when buying some soil at the nursery I asked about pots and she said there’s a stack of 3gal pots leftover in the back and to help myself. So 3 gal it is, can’t turn down free pots. Think they’ll be perfectly fine not to big not too small. Now cozy at home under the grow light inside. Can’t wait to see these things grow.

With Copernicia seedlings I once read that they grow especially slow if they don't get offered very deep pots. Can anybody confirm this? Also in general: Do potted palms grow faster in deep pots? Thanks a lot!
