When to Plant Tomato Plants in Greenhouse UK

Tomatoes are one of the most popular greenhouse crops in the UK. They are easy to grow and provide a delicious harvest throughout the summer. However, planting tomato plants at the wrong time can result in poor yields and stunted growth. In this article, we will discuss when to plant tomato plants in the greenhouse in the UK.

Timing

The ideal time to plant tomato plants in the greenhouse in the UK is from late March to early April. This is when the soil has warmed up enough and the risk of frost has passed. The temperature in the greenhouse should be around 16-18°C during the day and not below 10°C at night.

It is important to note that tomato plants need a lot of light to grow and develop. Therefore, planting them too early in the season may not be ideal as there may not be enough sunlight in the greenhouse to encourage growth. On the other hand, planting tomato plants too late in the season may lead to them not producing fruit before the end of the growing season.

Varieties

There are many varieties of tomato plants available, each with their own unique flavours and characteristics. When selecting tomato plants for your greenhouse, it is important to consider the space you have available, the temperature in the greenhouse and the amount of sunlight it receives.

Determinate tomato plants are a good option for those with limited space as they are bushy and do not require staking. Indeterminate tomato plants, on the other hand, grow taller and require support such as a trellis or stake. Cherry tomato plants are ideal for those with limited space as they take up less room and produce small fruit that is ideal for snacking.

Planting Process

Before planting your tomato plants, it is important to prepare the soil in your greenhouse. The soil should be moist and free-draining. Use a mix of compost and soil to create a nutrient-rich growing medium. You can also add slow-release fertiliser to the soil to provide nutrients to the plants throughout the growing season.

Plant your tomato plants in individual pots or containers, ensuring they are planted at the same depth they were in their original containers. Cover the soil with a layer of mulch or straw to retain moisture and prevent weed growth. Water your plants regularly and feed them with liquid fertiliser every two weeks.

In Conclusion

Planting tomato plants in the greenhouse in the UK requires careful consideration of timing, variety and the planting process. By planting your tomato plants in late March or early April, selecting the right variety for your space, and following the planting process, you can enjoy a bountiful harvest of delicious, fresh tomatoes throughout the summer.
