I prefer the Bowl shape better than a saucer.
But if you've ever watered a flowerpot, youll notice the dirt gets pushed to the sides.
That's the shape of bowl you want for your garden plants.
Same with any plant really.
It looks like it's either too dry,
some of the roots are dying,
or it gets too much sun/heat.
Did you acclimate it to avoid transplant shock/light burn?
Have you ever grown anything there before?
