Hello, I germinated Berberis julianae from seed. As you may know, it requires cold stratification, etc. so it isn't that easy to regerminate. I originally had 4 seedlings, but they all have died except this one. I don't know what the problem is. Recently, it sprouted the new green leaf and its most recent addition is the purple leaf on the left... However, all the older leaves seem to be "half dead". I am not sure what the problem is. I am new to growing things indoors. I do plan to plant it outside after the last frost so I am trying to make it as strong as possible until then. I also attached a picture of my grow setup where I was keeping it. After I removed it from the box and put it in the windowsill it sprouted the new green leaf... so I am thinking it prefers the windowsill over the box. What am I doing wrong? I have 3 60W CFL lights in the box.
