I need some advice on getting Oleander seeds started. I planted some on the 23rd of June in one of my seed trays. I used seed starter mix and put the seeds on top of the mix, misted and covered with the plastic top. I have these out in my greenhouse so it was plenty warm and there was quite a bit of moisture on the plastic top but I was still misting a couple of times daily if needed. Well, so far nothing has come up. Any ideas or helpful hints to get these or another batch started?
