Germination was erratic with some chillies last year. What were the factors? It’s hard to tell as the chillies can’t tell us. Temperature is cited as a key factor. This year we will be attempting germination as follows:
- Chitting, not in soil or vermiculite. This way it is really obvious what is going on with the seeds.
- Keeping a consistent temperature, night and day.
- A high enough temperature for the Chinense type chillies. These all seem to prefer a hot kickstart. It looks like a balmy 27 degrees might suit most chillies.
- Not excluding light. Airing cupboards are a no no according to some folk.
- Be patient. With some chillies listed as taking up to 6 weeks to germinate it it a waiting game.
- Maybe a soak the seeds in some warm strong tea, to act as a chemical scarifyer.
