I have four, one red, one pink, and two normal ones. They all need to be repotted this year. They don't do well in the ground here, because they rot in the rainy season. I will be repotting all of them soon in 50/50 potting mix and perlite.
I have four in big pots on my roof terrace. In January, a couple of weeks after I repotted them in moderately large, wide mouthed plastic pots in which I drilled extra holes, I checked them and two had had aphids and ants on several flowers.
Somewhere I read about mixing vinegar and detergent with water to spray on the bugs and kill them. Not very successful. In the next day or two all the flowers, 6 or 8 per pot, were covered with aphids and ants.
I sprayed the detergent & vinegar mixture on them all. In fact, at the time I figured that whether or not the mixture worked, it didn't matter because I certainly must have drowned all the bugs.
A few days later, all the leaves and flowers had fallen off. Clearly the mixture I concoted was far too harsh I had 4 pots of naked Adeniums. Not a pretty sight.
But they all came back.
Now, almost all are covered with flowers. I went about a month without doing anything to them until I began seeing little signs of growth at which point I began a slow watering regimen. After a month or so. the flowers began to return.
The moral of my anecdote is "don't give up." These are truly tough plants, in addition to being exotically beautiful, they clearly are thriving.
In lieu of fertizer, I use compost combined with fallen leaves, I water usually morning and evening.
Today they are all happy and blooming successfully. But none of them is anywhere near 14 feet tall.
My hope was that a message would go out through the world of aphids that there was a crazy woman on a rooftop trying to drown them. So far, so good. A couple of the plants have a few yellowing leaves but otherwise seem healthy. About 3 weeks ago, I spread a homemade compost & organic fertilizer mixture on top of the pots to take advantage of the warmer weather and more rain. They seem to be thriving. I water every 2 or 3 days.
I have the all the plants in plastic pots inside triangle-shaped cement pots on wheels with hand brakes. Several layers of drainage in each pot are assisted by the fact that all the roofs around here are slanted to drain off rain. A photograph of one of the smallest Adeniums is attached. bb
wow!!! Gorgeous! i have a question about my desert rose that I hope someone can answer...i have had this plant for 4 years and it has always bloomed beautifully up until this year. I get plenty of buds on it and then they just fall off without ever blooming. It has been in the same spot now for over two years and has never had this problem. I have 2 other small one in pots that are doing great. Anyone have any input on this??? Thanks!!
My big momma desert rose (pink) loves it when I give it orchid bloom booster. So, I mix 1/2 batch Miracle Gro and 1/2 batch orchid bloom booster and it is so happy. I have just purchased a smaller adenium (yellow) and I have started it on the same fertilizer regimen. It seems to enjoy it.
