Ummm...I gurantee a larger pot wouldn't hurt. If that's a one gallon pot, I'd find a 3 or 5 gallon pot and transplant today. What kind of soil are you using, and do have perlite in the soil?

Try to shade the pot itself from direct light/heat, too. You can actually steam the roots if too hot.

I'd leave the sagging stuff till it falls off. Not hurting anything anyway, and you already took the glamour shots, lol.
