I have two oleanders and they are doing great. The negative thing is I live in Michigan Zone 6. I will be bringing them into a room in my basement for the winter with my hibiscus. Can I prune these before I bring them in? And I understand I do it just above three leaves, is that correct? These are just beautiful, I do know they are toxic but want to have them year after year. They are a small tree about 5-6 ft. tall. Any help would be appreciated.
That's a really gorgeous Oleander you have there,is it Calypso?. I am lucky that I don't have to bring mine in here but the same would apply regarding the pruning..I prune mine here late autumn or very early winter or whenever they've finished their blooming season.Yes just above the leaf nodes.If you can,don't waste those cuttings,it would be too lovely to waste. Cut just below the leaf nodes for your cuttings.
brical thank you so much for the response. I have a fairly cool room without much light in my basement and I plan on putting them there and watering sparingly during the winter. I do that with a hibiscus and a brugmansia and they come through just fine so I am hoping that this will work. Yes I believe it is Calypso. I will do as you suggest with the cuttings. Too bad you are far away or I would share!
Now it is the end of May and I didn't prune mine last fall - I only have about 6 stalks and they are about 8 ft tall - not very pretty. If I do it now will more flowers come this year?? I am in No Georgia.
I have taken cuttings longer. I put them in water with fish charcoal to keep the water clean. I put a plastic bag over the container and watch it so there is not too much moisture or it will mold.
I don't like to leave them out side. Here in Arizona it gets colder at night by 20-30 degrees. I did just notice I have roots in one jar that is outside.
I don't think the root that fast, several weeks. Some I have never been able to root so I have to go back and get some of them again.
I don't know how thick of a cutting you should try. I have some pretty fat ones that I am trying right now because I have so many of that type.
I think water roots are fragile so be careful. I have heard that some people root cutting in sand. I prefer to watch my roots grow. If you have a lot of moisture in the container I have even gotten air rots from the cuttings.
I was amazed how much one of my little oleanders grew in the winter. I was able to take more cuttings from it than I thought.
When bringing the plants inside remember you can stack them into the other pots too.
Mine are able to stay outside and I love that. Now as I get around to it they are getting major trimming and shaping.
Don't forget to mark what your cutting are, so it as you cut. You will never remember what they are if you are working with a few cuttings.
I have a ton of plants I have no idea what they are until they flower. I don't know the name of many of mine but the heat makes a big difference on their color for me.
I will try and post some new photos soon.
I have also notices the petal shapes. I have some that look like the same plant, they color looks exact;y the same. I just notices that one has a pointed petal and the other in pointed in the middle of the petal. I will try to get photos but I am tied up for a while.
