Tomatoes are one of the most popular and versatile summer crops. Not only are they delicious and nutrient-dense, but they are also relatively easy to grow if you know the right timing for planting and transplanting.
Here are some practical tips on how to obtain an abundant production of tomatoes.
How they affect temperatures
Tomatoes are heat-loving plants and need lots of sunlight to thrive. They grow better at temperatures between 21 and 24°C (70-75°F).
It is important to plant seeds or seedlings when temperatures are stable and there is no risk of frost.
Tomato seeds should be sown indoors between March and Aprilready to be harvested from July to September.
However, the exact sowing period may vary depending on the tomato variety chosen.
Sowing indoors
Regardless of whether you plan to grow tomatoes in a greenhouse or outdoors, it is advisable to sow the seeds under cover initially.
Seeds germinate best at temperatures between 18 and 25°C (64-77°F).
If you plan to transplant tomatoes outdoors, seeds can be sown indoors six to eight weeks before the expected last frost date in your area.
Use trays filled with seed compost, cover the seeds lightly with compost and water. Place the trays in a sunny spot at around 18°C ​​(65°F) and the seeds should germinate in around 8-10 days.
When to plant in the greenhouse
If you are planning to grow tomatoes in a greenhouse, the seeds can be sown early, from late February to mid-March. The seedlings can be transplanted into larger pots towards late April or early May.
In a heated greenhouse, seeds can be sown as early as January, with transplanting into larger pots expected in late February or early March, for a harvested from May to June.
When to transplant outdoors
Plant tomatoes outdoors once the risk of frost has passed and the soil has warmed. The night temperature must be constantly above 10°C (50°F).
The seedlings should be moved outdoors gradually over a period of time period of one or two weeks to acclimatise to direct sunwind and temperature variations.
Tomato seedlings should be about 23-30cm (9-12 inches) tall before transplanting outdoors.
Also, consider planting other compatible vegetables nearby to improve production and discourage pests.
Variety and ripening times
The choice of tomato variety affects sowing and harvesting times. Different varieties have different maturation periods, so be sure to read the directions on the seed packet or plant label.
- Large, ancient tomatoes: Plant by May or early June.
- Smaller varieties: They can be planted later as the fruits ripen faster.
For example, ‘Sun Gold’ cherry tomatoes require only 57 days to ripen, which means they can be planted until early July and still produce a good harvest.
Trim unnecessary side branches from tomato plants to focus energy on fruit production.
Monitor plants carefully for signs of disease and apply appropriate treatments if necessary. Finally, be sure to water regularly and provide support to the plants as they grow.
By following these tips, you will be sure to get a rich and delicious tomato crop in your garden or greenhouse.
