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.

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 some original old very very hot chilli's that i saved from my Mothers plant which was originally her mothers plant.. They have been in the freezer since 1995. The seeds have an emotional attachment and i would love to be to grow these seeds into plants and hand onto the next generation - if it is possible. Having been in the freezer as a full pod - Would the seeds inside the pod be ok ? Would the plant cope outdoors with constant breeze? Any or all Advice would be much appreciated. Thank you

Hi Steve Seeds from your frozen whole fruit will not be viable. Seeds stored in freezer after drying at least 80% will keep viable in freezer but not fresh. Sorry

I would still try and grow some just in case.
