Tomato - Solanum lycopersicum

The taste of a ripe, sun-warmed, homegrown tomato is hard to beat.

They are easy to grow and other than regular watering and occasional feeding require little additional care.

Worldwide, there's estimated to be over 10,000 varieties of tomato with fruit of various shapes, sizes, sweet or sharp flavours to use in summer salads or to cook with, and red, orange, yellow and even black. They can be grown as upright/cordon so it can be difficult to choose which variety to choose there are over 10,000 varieties, of bright red, orange and yellow fruit. If you are planning to grow tomatoes outside pick a variety with smaller fruit. Large tomatoes take quite a while to ripen and the chance of blight or cold weather affecting them before they are fully ripe, particularly towards the end of summer, is quite large.

Sow seeds indoors on a tray of seed compost, from the beginning of the year until mid-April, water well and put on a sunny windowsill. The seeds should germinate within a couple of weeks. When they are about 10cm tall, prick them out into individual pots, moving them into their final pots, growbags or open ground in mid to late May. When they begin to flower, feed them weekly with a high potash fertiliser.

Cherry tomato varieties should be ripe and ready to pick from mid-summer, regular sized and beefsteak tomatoes take longer to ripen.

If you are growing bush tomato plants, don't pinch out the side shoots as you would for 'cordon' or vine grown tomatoes, else you'll only have one 'truss' of fruit at the top of the plant.

Try to water tomato plants in the morning, watering later in the day may cause them to sit in water overnight.

If the leaves of your tomato plant begin to turn yellow, water with a Epsom Salts solution of 1 teaspoon per gallon (4.5 L) of water.

Blight is a disease that spreads in warm, wet conditions. Growing tomatoes in the greenhouse or conservatory does seem to delay plants succumbing to the disease.

Tomatoes contain melatonin, which aids sleeping, beefsteak tomatoes having higher levels than other types.

Culinary use:

Great to eat straight from the vine or use in a number of recipes. For the best flavour, store tomatoes at room temperature. If stored in the fridge, they should be left on the side to warm before using.
