If you want a perfect pepper for lunchboxes, then this variety is ideal. It produced plenty of bright-orange, little peppers, most around 5cm long, which were sweet and tasty. The plants were short and compact, great for growing in pots. It wasn’t the earliest to ripen, but we still got about 14 ripe fruits from each plant by the end of September and plenty more ripening. It has an RHS AGM (Award of Garden Merit) as well.
We sowed the seeds of 10 varieties of sweet peppers in a greenhouse in March at our trial site in the Cotswolds. We used modular trays, filled with a . When large enough, they were planted into 7.5L pots. We used a and mixed in . The plants were put in a polytunnel and watered when needed. They were given an extra boost of liquid tomato feed when the flowers formed. The crop was counted and weighed until the end of September and tasted for flavour.
They need to be kept at 20ºC and germination takes around seven to 21 days. Grow the seedlings on in good light, and make sure that the temperature doesn’t drop below 14ºC at night.
When the roots are showing at the bottom of the pots, move into 2L pots and, after another month, into 7L pots of a that you’ve added some to, or into a . Transfer to a sunny, sheltered spot outdoors once the danger of frost has passed – in late May or early June if you’re growing outside.
Keep the compost moist, but not wet; peppers don’t mind being a little dry. When flowers appear, use a high-potash tomato feed weekly.
Harvest in: September
Allow fruits to ripen fully – most turn bright red or orange when they’re ready to eat, but others change to yellow.
Aphids sometimes attack the plants by sucking the sap. Remove any you find by hand.
This is a physiological problem that causes dark, leathery patches at the blossom end of the fruits. The immediate cause is a shortage of calcium in the developing fruit. The usual reason for this is erratic and/or inadequate watering, plus high temperatures.
