Might be watering them inadequately, missed the peak growing season, which is summer (most likely, though some are still growing) impatient or all of the above but I feel like that's the size they grow, apparently I've read somewhere that they're of the "ornamental" variety which means they're that size when they've matured, but the picture shows a bigger size. They're Thai Dragon Chilies. Unless I wait until next year to see if they grow bigger or to move them to a bigger pot.
Thank you! I should repot them next year in a bigger pot the next size up than this one, some are just about turning red that's why I haven't harvested them yet, need to think about overwintering them soon, kinda nervous I might get it wrong since I've literally just started this year with my sister heh so we're basically beginners here😅
That's good to hear, peppers are good to grow since we use a lot of it on our cuisines. Hope everything turns and grows alright for you!
