Pot them into separate containers, then prune them to keep them short and manageable. They will bush out and make fine houseplants, especially if they're a smaller cultivar from the start. The leaves look a bit lime-green and delicate....are they receiving enough fertilizer for thick green growth? (Pale color could be due to camera lighting, as well).

Thanks Jean and Josh.

Yeah, I will re pot and prune to keep them short.

Yes, Josh. The leave are a bit pale, I know. I have not fertilized them much, just lightly. I will boost it gradually. I didn't want them to go crazy.

Update:

On Josh's suggestion, I was planning to top them to stay bushy. But as was re potting them yesterday, I noticed that at 5" they are branching out and already have buds. I fertilized them a bit more. Seems that they are getting darker green.
The way it is going I might be harvesting some before getting them outside. What do you know ! I got myself an indoor garden. haha

MERRY CHRISTMAS everybody !

UPDATE 12/30/04

Shishito is amazing. They are about 9" tall. Keep getting bushy by branching out and are loaded with buds and have few flowers too; A tabasco-like ornamental is the same way but a little behind. Habaneros are moving slowly. Which is ago . They have plenTy of time till plant out.

HAPPY NEW YEAR EVERYONE !
