Hey
@Crassulover!!
Baja gave you some great advice!!
Pachypodium have always been kinda my thing. I'm sitting here in my living room right next two two seed grown P. lamerei of mine
Watering with pachyies can be a little bit tricky, and is going to largely depend on your soil. Now these two are currently dormant and so I'll very sparsely water them in quantity of water. In dormancy not only do you not want to water as often you don't want to water and give as much water as you would during growing season.
Now I have super fast draining soil mix only between 10-25% organica that is close to being pure stone aggregate. And during the growing season I water about every few days now here in Texas, and water completely through. This has always been my preferred style with pachyies. Mine have been grown like this since seedlings so they tolerate a little more drying out then ones you may buy. I have near 100% success this way but it's more regular tending.
It looks a little yellow like Chlorosis,(maybe it's just the lighting) which with pachyies some times is an over watering issue, it's really hard to say without being there, But you also have a terra cotta pot which I do not recommend for pachyies, I've tried it and they just do not do as well in them, it's a little too hard to regulate moisture.
Here's examples of good healthy leaf color for P. lamerei
