Hello. Does Chilli go out of season, if so, when?

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.

Hi. I have my own chilli breeding program going on, and am planning to use a combination of Thai chilli, birdseye chilli, Chilli Diablo, some stock chilli (generic, little spice, huge fruit, and Habanero. All these plants are growing in a full-sun position in neutral soil with some compost and old manure mixed in, making it slightly more acidic, but they seem to love it. I have noticed growth of up to an inch a week if Worm Castings and seasol are mixed with some water and sprayed onto the leaves of the stock chilli and diablo. As the leaves of these two are very large, foliar feeding goes down a treat. The birdseye and thai chillies have smaller leaves, so I just add it into the irrigation water, with equal results. The habanero I have left alone, as a bit of an experiment to see how maintenance-free this part of the veg garden is. All the plants (apart from the diablo) were started from seed in the middle of winter, indoors, and the Thai chilli and Birdseye chillies have been topped as half the crop from them will go into our special family chilli sauce. All plants have abundant flowers, some of which are ready to open, and average about 60cm tall. I hope this helps and inspires some peopleto get into chillies.
