GARDENING: Chilli growing is not all about intense heat

I'm a bit of a girl when it comes to chillies '“ I'm not a fan of very hot food, so chillifests leave me cold.

However, when I was sent a packet of Loco seeds to trial, it would have been churlish not to sow them – what a great plant. It’s compact (only grows to about 2ft) and bushy and covered with flowers.

You can’t deny how decorative it is – the inch-long cone-shaped fruits are held upright above the foliage like little fairy lights. The unripe fruits start purple/cream, changing from orange to red – the look like plump blackcurrants, but you’d get a shock if you ate one.

Decorative chilli Loco.

Loco, despite its name, is not supposed to be that hot – slightly less than a cayenne pepper, a medium heat level of about 24,000 SHU*.

Which Gardening Chilli Trials recommended it as a ‘Best Buy’ and it was bred in the UK.

You can sow now in a propagator, but make sure you have a good light source. Seeds cost £2.99 a packet from Suttons,*The Scoville scale is the measurement of the pungency (spicy heat) of chillies or other spicy foods in Scoville heat units (SHU), a function of capsaicin concentration, named after its creator, US pharmacist Wilbur Scoville.

If you’re a chilli fan, you can now buy seeds of the world’s hottest variety, Carolina Reaper, from DT Brown.

Available as young plants last season, Carolina Reaper packs a volcanic punch of more than 2,200,000 Scoville Heat Units (SHU).

The company’s Tim Jeffries recommends gloves should be worn when handling the plants and fruits, which should always be cooked and never eaten raw.

Carolina Reaper’s not simply about heat. It has a sweet, fruity flavour with chocolate and cherry undertones.

All super-hot chillies need to be sown early and require real warmth to get started. A heated propagator set at 28-30°C is ideal, because the hotter the chilli, the more time and heat it needs.

Rhubarb can be forced for an early crop. Cover a crown with a bucket and insulate the outside with straw or compost for added heat.

Lily bulbs can be planted in pots, for flowers this summer. After growing on in a cool greenhouse, they can be moved on to the patio when in flower.

Check on tender plants overwintering outdoors to ensure protective coverings are still in place.

Continue to deadhead winter pansies and other winter bedding. Pansies will carry on into the spring and even to early summer, if attended to frequently.

Cut off old leaves of hellebores that produce flowers from ground level to expose the flowers and remove possible foliar diseases such as hellebore leaf spot.

Look out for rots (such as crown rot, Sclerotinia, delphinium black blotch, black root rot and antirrhinum rust) on emerging perennials.

Many summer-flowering deciduous shrubs can be pruned now – those that flower on the current year’s growth, including Buddleja davidii, Ceratostigma, Hydrangea paniculata, Lavatera, Leycesteria, Perovskia, hardy fuchsias, and deciduous Ceanothus.

Prune Wisteria by cutting back the sideshoots shortened by summer pruning to two or three buds (2.5-5cm/1-2in). Avoid cutting off flower buds.

If you have any seedlings and/or cuttings in the greenhouse, make sure they are getting the maximum light available, or else they will become weak and leggy. If necessary, turn them once a day to get light on both sides.

This will stop them leaning over.
