Help Salvaging Oleanders
Don't laugh please! :D I don't have a lot of experience gardening, but I've rented a house with three oleanders in the back that don't look like they've ever been pruned. I decided to give it a try and cut one of them back, and quickly realized that I have no idea what I'm doing.
In the pic I've posted, the oleander I tried my handiwork on is on the left, there are two left I haven't had the guts to touch until I get some advice.
I'd like them to become tall, mostly vertical bushes, or maybe a nice tree or something. Hopefully I'm not being so vague I can't be helped!
Any aid would be appreciated.
