Running out of ideas--long--sorry
I'm about ready to give up on my Adeniums. I just don't know where to put them to keep the leaves on them.
I had them in the sunroom during winter/spring and they all got leaves and some flower buds in midspring and they were all looking fat and happy. After awhile, all the leaves fell off. I attributed that to the trees leafing out and blocking the afternoon sun to the sunroom, but maybe I was wrong.
Last summer I had them outside in the shade structure where I keep most of my cacti (I'm at 4700 ft so the sun is very intense and I wanted to protect them from the wind-even under the shade cloth the light meter is at the max) no leaves then either. The previous summer I had them under morning sun out by the vegetable garden. They were shaded from the harsh afternoon sun by a small tree; still no leaves.
Now I have them where they get full sun almost all day long; still no leaves. Could it be due to the night time temps getting too low (last week it was in the 40s, but they average in the 50s); the humidity is so low or the daily winds we have here? Or all of the above?
They are right at the edge of the sprinkler so it is a little more humid there and they are near the house so they stay a little warmer. My biggest one will get flowers, but I want leaves too. They are in a flower bed where dahlias, roses and daylilies are very happy.
I feed them with fish emulsion, should I rotate with something else?
I realize all of our conditions are different, but does anyone have any suggestions? I want them to be healthy, happy and leafy.
So is there any hope considering my climate?
