How Far Apart To Plant Oleanders?
Oleanders get very tall and wide. Not sure if you are wanting to make a hedge out of them or not, but would suggest you plant them at least 4 to 5 feet apart. I have one in my backyard that grew about 8 foot high and 5 feet wide. You can cut them back about halfway in the spring if you want to for more blooms in summer, but it is not absolutely necessary to prune them back.
