🌱 Sowing & planting
Tomato ( Solanum lycopersicum ) is a heat-loving annual that you Always sow in advance. First indoors or in a heated greenhouse, then prick out and plant out in the final location.
- Sowing depth: approximately 3 mm.
- Pre-cultivation: sow in seed trays and prick out when there are 2 true leaves into pots of ± 9 cm.
- Germination temperature: 21–27 °C.
- Germination time: 🕒 6–10 days.
- Plant out when the plants are 25–50 cm tall and no longer sensitive to frost.
- Planting distance: 45–60 cm between plants (depending on variety and support), 75–80 cm between rows.
- Growth cycle: 🕒 approximately 160 days from sowing to final harvest.
📅 Growing times throughout the year
There are roughly two types of cultivation: under glass (greenhouse/greenhouse) and in open ground out of the rain.
- Pre-sowing indoors / greenhouse / glasshouse: sow indoors from mid-February to mid-April, plant out under glass from mid-April to the end of May, harvest from mid-July to September.
- Open ground (out of the rain): sow indoors from March to mid-April, plant out outdoors from mid-May to early June, harvest from early August to September.
Combine both crops for a long harvest period from summer to autumn. Under glass you get the earliest and most reliable harvest.
