According to Craig, the best tomatoes are grown early. They can be grown indoors as early as January, transferring to the garden after two months when the weather is milder.

What you need to grow your own tomatoes

"To grow tomatoes successfully from seeds, you'll need some starter trays and 3-4 inch pots to transfer them into after they begin to grow. You'll also need rich, fertile soil or peat-free potting compost and a good spot with plenty of sun (around eight hours a day) and shelter," Craig recommends.

How to sow tomatoes at home

Sow seeds from January to April, about ¼ inch deep. Use deep pots or trays, under glass, with a temperature above 18°C (around 25°C is best). Tomatoes are sensitive to cold and love heat, which helps them to grow. Keep the soil moist but be careful not to overwater, making the soil soggy and inhibiting growth

Once seedlings are large enough to handle, around five inches tall, transfer them into individual containers or a seedbed. Once the last frost has passed, it is safe to plant them outside. If night temperatures drop below freezing, keep them inside for now.

How to prepare your tomato patch

To ensure your tomatoes have the best chance of growing plump and juicy, you need to check your soil is of the highest quality possible with four easy steps:

  • Remove any larger weeds and debris
  • Treat soil with weed killer
  • Dig over the soil to a depth of at least 12 inches, then rake until the ground is level, which aerates the soil, helping oxygen and moisture reach the roots to encourage growth.
  • Before planting, water the soil and work in a fertiliser

Tip: you can create your compost using old fruits, vegetables, and coffee grounds, which will help fertilise your plants at no extra cost.

Dig deep enough for the soil to cover about two-thirds of the plant, encouraging strong roots and healthy growth. Each plant should be around 20 inches apart in rows, and the spacing of each row should be double that. Make sure to water the plants consistently. When watering, check the soil's moisture; the water should go around ten inches deep.

Tomato trellises and support stakes can help your plants to grow. Don't grow tomatoes near cabbage, fennel, corn, or potatoes, as this will harm the tomatoes' growth.

How to maintain your tomatoes

Water regularly and feed weekly with a high-potash fertiliser once the plants begin to flower. Side shoots may appear on your tomato plants. You can prune these, which helps reduce the risk of disease and how much support is needed, but it's not necessary.

When to harvest your tomatoes

It is safe to harvest tomatoes in the summer, from July to October. Tomatoes ripen after picking but wait until they are beginning to change colour before harvesting. They should come off the vine easily. If not quite ripe, keep them in a well-ventilated area at home until they are ready to eat.
