Every so often (2x so far) ive had 2 of the first leaves it put out since i got it go half yellow with a black dot on the yellow, but none of them fell. So i unpotted it, the roots looked a bit too wet, so i let it dry. Its in bonsai soil (mostly pumice and small pebbles with a little bark) as im afraid of it getting root or trunk rot. Once i let the soil dry for a few days, the half yellow leaves HAVE SINCE DROPPED, but now the caudex looks slightly dried out, any help? im overwatering right? Also, both of my adenium arabicums look very different. The evergreen one in the red pot had the issues btw. The other one has a green caudex and deciduous looking leaves.i tried adding a photo, but it failed. So heres another! The one in the red pot is the offender.

Welcome! Wolfy.

It would be most helpful if you could post pictures of the plant, so we can see exactly what you're talking about. My Adenium does tend to look scrappy a lot of the time (leaves seem to prematurely die off and fall) but I have learned to tune most of that out, as long as there are good leaves happening somewhere. They can be moody. Now what you're seeing could be something serious (a photo might help) or it could be a moody plant that's maybe not quite used to its environment, and just needs to get into its groove. Is this a new plant?

Your watering frequency is basically what determines whether you are overwatering or underwatering, and as a general rule you need not be overly concerned about overwatering during periods of active growth, when the plant is leafy and the weather is warm. With good drainage (say 50% pumice or another kind of rock, whether bought that way in a bag or concocted by yourself) Adeniums love lots of regular water and warmth when they're really going. Similarly you can safely assume it's good idea to back off on the watering frequency during winter dormancy, and at that time treat the plant like a succulent. Which is to say water well and then wait until the soil is almost dry before watering again.

The greater part of discretion occurs at the interface between dormancy and growth, more or less at the stage you're describing, when plants are just coming into or out of growth. You have to get a sense through experience of how to manage the transition. When to encourage growth with extra water, when to hold back. I would only say imagine it as a continuum and try to water in moderation (which might be once a week with good light) until you see more leaves. Strong light definitely helps with the watering and tends to curb any tendency toward overwatering.

We have an Adeiums forum here that would probably be helpful. If you scroll through the forums list you can ask over there.

Just re-reading the text at the bottom of this page... I think we can answer the question here.
