Tomatoes find ideal conditions on the windowsill. Here it is warm and bright enough to act as a focal point in the cultivation. Discover all the options from sowing to harvesting here.
How to grow tomatoes on the windowsill?
To grow tomatoes on the windowsill, distribute soaked seeds in pots, cover them thinly with soil and keep them moist. Place them on a partially shaded windowsill and increase the brightness after germination. Care includes regular watering, fertilizing and pinching out unnecessary side shoots.
Growing on the windowsill – always in view
The windowsill not only puts tomatoes in the right light, but also permanently in the field of vision. This means you won't miss any development steps during cultivation.
- Spread the soaked tomato seeds 3 centimeters apart and sift over them only very thinly
- moisten, cover the pot with foil or place it in the mini greenhouse
- place on the partially shaded windowsill on the west or east side of the house
- at constant temperatures around 20-24 degrees, the cotyledons appear within 2 weeks
- Prick out from a height of 10 centimeters, place cooler and brighter
If the growing pot is well rooted, the next step is to repot it into nutrient-rich, compost-based vegetable soil. Now the young tomato plants can be placed on the sunny south-facing windowsill so that they don't rot.
Uncomplicated care until harvest
From mid-May, the large tomato varieties are released outdoors or moved into the greenhouse. Small cocktail tomatoes in pots can stay on the windowsill because their pretty flowers steal the show from many houseplants. Care revolves around these aspects:
- Water tomatoes on the windowsill regularly
- do not water over leaves and flowers
- pamper with special liquid fertilizer every week up to 14 days
- If necessary, remove unnecessary side shoots
- shake occasionally during flowering to stimulate pollination
Harvest the tomatoes on the windowsill when they are completely colored. There should be no green spots left on it, the peel will give slightly under pressure and the predetermined breaking point on the fruit stalk will immediately collapse.
