Sweet pepper plants can be grown from seed indoors and later planted out in summer to fruit in your windowbox, provided that they have a good sunny and sheltered site to move to. They like a fertile, moisture-retentive soil that drains well.
Sow seed: Thinly in pots, lightly covered with potting compost in early to mid spring, kept at 18 – 21oC. Once germinated, grow on at 16-18oC.
Varieties: Ariane (Orange fruits), Gypsy (Long, green to red), Luteus (Yellow), New Ace (Red)
