Hello!

I'm really new to planting any type of tree and I had a question if anyone out there wants to help a newbie like myself.

I got these olive trees rooted from cuttings and I'm planning on planting them in large containers (so I can take them in in the winter). When I got the cuttings the branches were growing off the stem at an angle. Do I need to worry about the tree growing up straight from the angled stem, or will it fix itself on its own as it grows? Should I plant the whole cutting at an angle to straighten the trunk. Right now they are buried up to where the roots end but could I bury them further and straighten them? (see the photo)

If anyone has any ideas on what I should do I would be grateful! Thank you!
