They do tend to produce the best crops in the first year, but for some reason one of my plants has gone mad this year (second year) and produced a ton of large, spicy, long chillis. Next year might be pushing it, so I have started collecting seeds from the best fruits.
That said, I do grow mine in the office these days, as they love the constant temperature and humidity. You just need to keep on top of the watering and feeding, otherwise they get a little dried out.
Current plants are:
3 x Black Pearl (flowering and fruiting heavily)
1 x Chilli Pyramid (ditto)
1 x Cherry Bomb (looking a little peaky, but fruiting)
1 x Pinnochio’s Nose (Huge, fruiting massively)
1 x Tabasco (On death row. Three small chillis on it and few flowers)
I might try and get the Mauii Purple and Peter Peppers going over winter, and clear out all the rubbish plants in early spring.
