I just bought a house that has 3 oleander plants in the yard. They are about 6 foot tall. The problem is that they are not bushy or full at all. They are more like several 6 feet sticks with only about the top 2 feet with leaves on them. I noticed some seed pods on them so they have bloomed recently, I guess. My question is, how do I get them to be fuller and bushier. Do I prune them back? And how exactly should I do that? Should I chop them way back like I would a hibiscus? I was going to post a picture but I dont know how to do that on here.
