Requirements for growing conditions

Onions require a lot of light for active growth, so they should be placed on a windowsill where they will receive enough sunlight.

The ideal temperature for onion growth is +18...+24°C. It is important to avoid sudden temperature changes and drafts, which can negatively affect the plant. Onions also require evenly moistened soil, but waterlogging can lead to root rot, so it is important to monitor the moisture level. Water the onion when the topsoil begins to dry out to avoid excess moisture.

To plant onions, use light, loose soil with good drainage. You can purchase a ready-made mixture for vegetable crops or prepare the soil yourself by mixing peat, humus and sand in equal proportions. This will provide the plant with comfortable conditions for growth and development.

Ways to grow onions on the windowsill

One of the most popular methods is growing onions in water. To do this, choose healthy medium-sized bulbs, remove the top layer of husks and lightly trim the top.

Green feathers can be cut off as early as 2-3 weeks after the start of growth, which makes this method quick and convenient for obtaining fresh herbs.

Then fill the container with the prepared soil, leaving 2-3 cm to the edge. Bulbs should be planted to a depth of 2-3 cm, leaving a distance of 2-3 cm between them. Water the plants regularly, keeping the soil moist. Green feathers can be cut off 3-4 weeks after planting, obtaining fresh herbs for use in cooking.

If the onion does not grow, it may not have enough light or heat. Make sure that the plant receives enough sunlight and is at an optimal temperature.

To avoid this, reduce the frequency of watering and ensure good drainage, which will help prevent water stagnation in the soil.

If onion growth has slowed down, you can feed it with a weak solution of complex fertilizer. This will help activate the growth and improve the quality of the greenery.
