I have a Chilli Peter bush that I have had a lot of peppers off, can I keep it growing for another season? Thanks Aaron

I have a chocolate Habanero plant which I brought inside to over winter and I'm amazed to say it actually flowered and I see it has fruit developing now (mid August). These chilli plants need a long growing season and I'm optimistic that I'll get masses of fruit from this plant in the coming months for my hot sauce recipes. Did you manage to over winter your chilli plant Aaron?

how long does it take for chilli seeds to start to show in a seed tray. I've put mine in almost two weeks ago and no sign of them yet.

I'm in Ft. Lauderdale Florida (10B). I have the same issue. I've got a plethora of differing varietals that I germinated outdoors in Solo cups beginning in March. Some plants are 6"-8" tall while others are just starting to sprout. My Thai Chili Peppers are growing exceptionally well while the bell peppers are taking there "sweet" time getting here. The struggle is real.

Do you use a plant heat mat. It can be bought online or may be found at garden centers like Lowes or Home Depot. Peppers like heat for good propagation

do chillies continue to ripen once they have been picked? Cheers Paul

Yes, they will ripen slowly in the same way that capsicums do. Probably need to be starting to change colour.

I'm actually in Thailand but your site doesn't list that. Having a hard time growing chilies here and looking for any hints. Soil has plenty of nutrients but does not dry out due to the rains and clay underlayer. At this point I'm thinking of adding sand to the soil to aid in drainage. I've dug a hole in the garden down to the clay layer and filled it with water. It drained within 5 minutes so it's really about my topsoil quality. Thanks!
