British tomatoes

SIR – With regard to homegrown agricultural produce (Letters, February 28), in Wissington, Norfolk, we have Europe’s largest sugar beet factory.

Tomatoes were also grown in 18 hectares of greenhouses, using recycled carbon dioxide and water from the factory, and thousands of bees helped with the fertilising. More than 140 tons of lovely, succulent tomatoes were produced annually.

However, in 2016, tomato production ceased. The glasshouses are now used to produce medicinal cannabis.

SIR – I have grown tomato plants for many years.

The process is very straightforward. Take the seeds from the tomato and dry them. Plant them in a pot with soil or special fibre from a shop. Put the pot in a warm place and water when required.

When the plants have grown, move them to a larger pot or plant them in the garden in a sunny place. Water them when needed.
