5 ways to speed up the growth of onions on a feather on a windowsill

Growing green onions on a windowsill is convenient and easy. But in order to get a decent harvest, you should know some of the intricacies of planting and care.


The procedure of soaking the bulbs before planting accelerates the photosynthesis of plant cells, and increases the germination of greenery several times. Soaking disinfects the seed, protects it from decay, and increases the immunity of the culture.

Soaking, as a rule, is carried out in hot water with the addition of 1-2 tbsp. l. honey and a few aloe leaves. Young bulbs should be in solution for 30-40 minutes.


This method involves growing a crop without using soil. Only liquid nutritional formulations are used. The basis for placing the bulbs is a plastic or glass container, which is filled with liquid.

Feather onions can be grown in a variety of hydroponic designs. The most practical option would be a Styrofoam sheet with funnels cut out for the bulbs. It should be placed over a wide container of water.


With this technology, no special solutions and substrates are required. The bulbs grow in a suspended position. Growth stimulation is carried out by regularly irrigating the plant with organic mixtures instead of classical irrigation.

The plantings are moistened with a spray bottle. This is the most efficient irrigation method. After all, drops of the sprayed solution do not penetrate into the soil, but immediately into the pores of the root system of the onion. Thus, its nutrition is provided.

Temperature rise

Despite the fact that onions are a very cold-resistant crop, germination of seeds at low temperatures can take several weeks. Increasing the air temperature in the room accelerates the emergence of sprouts.

You should know that at a temperature of 20-23 degrees, the first shoots will appear in a week. To accelerate the further growth of the onion, it is recommended to keep the heat within 24-25 degrees. Higher temperatures will retard development.


Thanks to top dressing, crop growth is accelerated, its yield increases, and the size of the bulbs increases. To get a lush green mass, fertilizers must be applied strictly according to the timing and dosage. Otherwise, irreparable harm can be caused to the plant.

For the rapid growth of greens, a nitrogenous solution is required. It is prepared from 10 liters of water, 40 g of superphosphate and 20 g of table salt. The resulting composition should be used for watering the bulbs, as well as for regular spraying.

An aqueous solution of compressed yeast is no less effective. A bucket of water will require 200-300 g of product.

Wood ash, infused with boiling water, will help stimulate the growth of the bulbous head, and also accelerate the appearance of green mass. At the same time, it will give the plant the necessary minerals for full development.

1. Green onions

Topping my "hit parade", of course, green onions. Probably, at least once in his life, everyone grew it on the windowsill, even if only in childhood - out of curiosity. This is an ideal plant for a home garden: fast growing, unpretentious, useful.

As planting material you can use both onion sets (large fraction - samples), and ordinary onion-turnip. I tried both options from sevka (or small turnip), the yield, of course, is less - the bulb is depleted faster. But the feather - for my taste - is softer and more tender. In addition, the small onion takes up less space when planting. A large bulb produces more greenery, its feather is usually larger, and it takes longer to harvest.

If you don't have enough of your own turnip onions to be used for forcing, you can specially buy them in the fall of samples - in supermarkets and specialized summer cottages they sell them at the end of the season with good discounts. I would not recommend purchasing such planting material for a turnip, but for distillation - just right.

You can plant onions for distillation in small containers with water or nutrient solution (so that the onion does not fall into the water, but only touches it) or into the ground. I personally like the second option more: the bulbs on the water often begin to rot, exuding a specific aroma with ground ones, I have never had such an incident.

In the soil for planting, I certainly add a hydrogel soaked in a solution of Gumi (this biological product strengthens plants, additionally nourishes them, and increases resistance to diseases). In room conditions, the soil substrate dries out quickly, and the hydrogel prevents the bulbs from suffering from moisture deficiency.

You can find Gumi preparations and hydrogel for planting in our catalog, which combines the offers of various garden online stores. View a selection of these products:

To always be with the harvest, it is best to plant an onion regularly - every 10-14 days... Then, by the time the crop is fully harvested from the first "bed", the greens will ripen on the next - and so on until spring.

I use small plastic boxes for planting. I pour expanded clay at the bottom (there are no holes for the drain of excess moisture in the boxes, so drainage is necessary), on top - soil with hydrogel up to about half of the box. Having slightly compacted the mixture, I plant the bulbs in it close to each other, without burying them in the soil. I water it abundantly - that's all.

Since I plant usually already sprouted bulbs, the harvest does not have to wait long. I do not carry out any specific procedures (pruning, soaking, etc.), which are often recommended to be performed when forcing onions on a feather, - I do not see a special need, and there is always not enough time. But if you, friends, have such an experience, and you see the benefits of such processing, be sure to share your opinion in the comments - the recommendations of practitioners are always invaluable!

Home-grown cucumber varieties

It is very important to know which varieties are suitable for growing. It should be noted that at home, plants will not be able to pollinate. Therefore, it is best to take parthenocarpic cultivars for greenhouses. These are exactly the varieties that are capable of producing fruits without pollination.

Parthenocarp (from the Greek. parthenos - "virgin" and karpos - fruit literally - "virgin fruit") - a special case of parthenogenesis, virgin fertilization without pollination in plants, usually with the formation of fruits without seeds.

Modern parthenocarpic seeds are highly productive. They have several ovaries tied on one stalk, and such a plant can bear fruit for quite a long time.

Self-pollinating varieties can also be planted. Novice gardeners first of all need to choose varieties that are resistant to temperature extremes, lack of light, that is, they are the most unpretentious.

When choosing seeds, pay attention to the following:

  • Fruit appearance
  • Time from sowing seeds to technical ripeness
  • What species does the hybrid belong to?
  • Growing conditions.

What varieties can you choose for sowing?

  • Cloud F1 is an early and productive hybrid. Fruits are even, short, dark green up to 10 cm long. Fruiting is long. The beginning of fruit collection is already 46-50 days.
  • Madrilene F1 is a high yielding hybrid. The fruits have a wonderful taste and aroma, they never taste bitter. Length up to 8-10 cm. The first fruits in 38-40 days.
  • Cybria F1. Fruiting is abundant and long-lasting. First collection in 49-57 days.
  • Crunch F1 is a self-pollinated hybrid with side shoots. Therefore, take care of a spacious growing area in advance. The first fruits in 1.5-2 months.
  • Window-balcony F1 - mid-season hybrid, begins to bear fruit in 50-55 days, female-type plant, medium-growing. Resistant to powdery mildew and low temperatures (and in winter it can be cold from the window). It does not require a lot of light, that is, it can do without additional illumination.

How to prepare and plant seeds

  • To improve germination, it is recommended to warm up, soak and harden the seeds.
  • Submerge the seeds in warm water for a couple of days and change it daily. Seeds that float despite being soaked are best discarded.
  • Soaked seeds should be placed in a rag in the refrigerator for a day for hardening.
  • Sow the soaked seeds into the prepared soil, in holes about 1.5 cm deep. The recommended distance between the holes is 5 cm, I sowed more often, and then weeded out and thinned out excess greenery, trying to maintain a relative splendor and decorative effect.
  • The temperature on the windowsill should be at least 20 degrees, without drafts. If the wind blows around the house, cover the ground with plastic or a greenhouse. Expect seedlings in about one and a half to two weeks.
  • Use a mild potassium permanganate solution to protect against mold.
  • In strong light, after about 2-3 weeks, you will be able to harvest the first crop of fresh herbs.

As you can see, it takes about 40 days or one and a half months from sowing to harvesting greens. Not everyone has the patience to wait and then not eat the result in a few hours.

General recommendations

Anyone who wants to get a winter garden and start planting greenery on the windowsill needs to adhere to general principles. Here is some of them:

  1. As a container, you can use pots and decorative containers, which will not only help in growing greenery, but also become a beautiful addition to the interior.
  2. For germinating seeds, you can use not only soil, but also sawdust, paper, hydrogel and cotton wool.
  3. A universal mixture for vegetables is suitable as a soil.
  4. For the successful cultivation of greenery, a layer of expanded clay pebbles should be placed on the bottom of the container.
  5. Plants need to be provided with enough light. If there is not enough natural light, then you can resort to additional lighting with fluorescent lamps.
  6. For uniform growth of greenery, it is recommended to periodically rotate it 180 degrees.

Knowing all the principles, you can grow greens on the windowsill in an apartment without much hassle.

Many plants are completely undemanding to care and only need regular watering. A variety of green herbs can become a regular guest of the table even on frosty winter days. All that is required for this is a container of soil and a little patience.
