Adeniums are by far my favorite plant.  They also tend to be vastly misunderstood by most plant lovers.  I hope this guide will help you in your growing endeavors.

Please keep in mind the difference in climates we may have and make appropriate adjustments.

Potting mix is critical for success. A regular store bought soil mix in most cases is not sufficient for good growing conditions.  Our spring and fall here in Oklahoma is usually very wet. An overly wet mix that holds water mixed with cool temps is not a good thing.  Those conditions along with a peat based mix can lead to root rot.  A course, well draining mix is a must.   If you can squeeze you mix when wet and it holds together, it’s not course enough.

We are blessed with a lot of sun in Oklahoma which is a good thing for Adeniums. Most of mine when outdoors during the growing season, April through September, get full sun. My favorite Adeniums are grown on my back porch and they get a little late afternoon shade. But for the most part it's sun from sunrise to sunset.

Adeniums when growing want water. A healthy growing Adenium need not dry completely out before watering again like many other succulents. Think of them as a banana or tropical hibiscus and water appropriately.

This summer was the hottest summer here since the dust bowl year of 1936. Adeniums in full sun were getting watered almost every day. Heat may slow blooming some, but they still grow in hot weather. I had some soil temps hitting 120 degrees with plants sitting on pavement. They were actively growing and setting buds.

I prefer a 15-9-12 Southern formula 9 month time release fertilizer in the soil and using a Peters 20-20-20 about twice a month when watering.

As long as your plant is actively growing, it's ok to water. As temps cool, the frequency will drop. It’s Nov. 1st now and I'm watering plants about once every 3-4 days in the greenhouse right now.

When winter hits here, most of my plants will defoliate. No more water for them until spring. I always have a few that I guess are a little more hardy and continue to hold leaves and bloom even with very cool nights. They are allowed to dry out completely before watering.

Adeniums can be kept indoors as a houseplant through the winter.  They will bloom if kept under lights or close to a good south window with unrestricted sun.

Hope this helps.  Please contact me if you have any questions.
