A soft brush is better for pollinating, or a cotton bud… Been doing that a lot for the plants I have at the office.
A quick inventory of the office garden reveals six numex twilight plants (all in fruit and doing really well), a Scotch Bonnet (still coming up), a Cheyenne (still coming up) and a numex twilight that has been outside at home and is a little yellow and poorly right now. All the numexes were grown from seed, although I did lose about half of them over Christmas when the people here forgot to water them for a fortnight.
The trick to getting them started is to use moist/damp, not wet compost, then get the seed tray covered in a clear plastic bag. Seven to fourteen days in an airing cupboard should see them germinating, then it’s just a case of looking after them and re-potting as they get bigger. To be honest though a single plant in a six inch pot should do them fine.
Pruning is essential. Too “leggy” and fruiting suffers. A friend at work recommends following the main stem up and then cutting it at the first “V” up. This gets them bushing out, not up, and makes them fruit better.
