You are right the plant looks very good, just stymied.
You could always dig it up carefully and shake off some soil,
and root prune it a little, then put it in an appropriately-sized
pot. Might help rid the soil of the problem, if that is where it lies.
Or an all out root clean-off, washing off all the soil, trimming
the roots a bit, and replanting/potting in clean soil.
handle lots of sun!
The timing is an issue. I've got some travel plans coming up. I hate to make a lot of stressful changes with this plant, and then have to leave it on it's own for a week. I've got the neighbor watering my plants. But it would be frustrating for things to go wrong, and not be around to learn anything from it.
My 2019 PDN x BMJ peppers are playing out like "The Tale of Two Pepper Plants".
It was the best of times... It was the worst of times...
One of my PDN x BMJ plants that I grew from last years saved seeds (non-isolated) is doing really well.
Although it doesn't have any peppers yet, it inherited a crowded slot in my pepper plot. So it's been putting all it's energy into growing taller than the other pepper plants around it. It's growing nice and straight, and hasn't even needed any support from the nearby stakes. To my relief, it's been handling the heat really well so far.
In this picture, it's just to the right of the ruler (I did mention it's slot became crowded. )
Another PDN x BMJ (also from saved seeds from last year) isn't doing hardly anything. It's only about 8 inches high (that's being gracious).
They're only a few feet apart from each other.
I'm really suspicious the problem is with the gardener, and not with the plant. But I'm at a loss for explaining why one is struggling so much.
But I'm really happy with the taller PDN x BMJ. It looks really healthy. I'm not worried that it doesn't have any pods yet. I had a few issues that delayed my start this year. And since it's a chinense, and since it really needed to put it's energy into growing, I'm not surprised it's waiting to put out peppers. There's still plenty of time for a fine harvest by fall.
DEFINITELY Aribibi Gusano in that one! I'm PRAYING for white on this one! If so...I WANT WANT WANT seeds!
I'll keep everyone updated.
Although, I've heard red is usually a dominant trait in peppers. If you cross a stabilized red pepper with a stabilized white pepper, the F1 generation will probably be red (this includes a simplified assumption that the color is controlled by a single trait).
But, in the F2 generation, 1 out of 4 on average might be white (again, assuming it's controlled by a single trait).
Since you didn't mention it, is your bubbler working well?
Your model looks different than mine, and I know Aerogardens have different styles of bubblers. So you may be having a different problem than me. My Aerogarden has a diffusing stone that plugged up. I just removed the diffusing stone, and let the air bubble directly into the water. For now, it seems to be working OK.
Something's been eating just the bottom of peppers!
I hate to admit it, but I may have contributed to this problem.
I've been broadcasting crushed red pepper into my raised beds in an attempt to deter the squirrels. This may have had the unintended consequence of conditioning the squirrels to develop a taste for spicy food!
Oh well, it could be worse! If they're gonna get curious about my peppers, I'd rather they get into my Cayenne peppers than into some of my more interesting varieties.
