When growing yellow cherry tomatoes, ‘Summer Sun’ F1 is one of the most reliable choices due to its remarkably sweet flavor. It is a vigorous, indeterminate hybrid variety that yields a very abundant harvest in greenhouse conditions. The plant possesses strong natural disease resistance, which simplifies maintenance and ensures a long-term harvest during the Estonian summer.
The plant forms large clusters where round fruits weighing 15–25 grams ripen. Due to their high sugar content and balanced acidity, these cherry tomatoes are excellent for fresh consumption, fitting perfectly in salads, on appetizer platters, or for snacking straight from the vine. One package contains 5 high-quality seeds.
Usage and Cultivation Instructions:
-
Sowing time and pre-cultivation: Indoor sowing in pots or seed trays is recommended from February to April. Maintain a soil temperature of 22–25 °C for germination.
-
Sowing depth: Sow seeds approximately 0.5–1 cm deep in slightly moist seed-starting soil.
-
Location: Prefers a sunny and warm environment; ideal for heated or unheated greenhouses.
-
Planting and spacing: Transplant into the greenhouse only after the danger of frost has completely passed. To ensure good air circulation, leave 40–75 cm between rows and 50–100 cm between plants within the row.
-
Harvesting: Fruits ripen gradually in the second half of summer, typically from July until the cool autumn weather arrives.
Tips and recommendations:
-
As this is a vigorous and tall variety, plan for a sturdy support system immediately, such as specialized tomato twine or strong stakes.
-
To achieve an abundant harvest and the best flavor, regularly pinch off all side shoots (suckers), directing the plant’s energy solely into fruit development.
-
Always water the plants in the morning and as close to the roots as possible to keep the foliage dry – this is the simplest way to prevent fungal diseases in a closed greenhouse.
