Seedlings: care, temperature, backlight, watering

Garden plants

Hello dear friends - summer residents, gardeners and gardeners!
Many of you are already sowing vegetable and flower crops for seedlings, and today I want to remind you of several important points that must be taken into account immediately after the emergence of seedlings, so that the seedlings do not stretch out and grow strong and healthy.

When to remove the cover from seedlings

After the first shoots loops appear in containers or in cups, it is necessary to remove the film from the crops or open the container lid to allow the sprouts to straighten and begin to get used to the environment.

This does not apply to seedlings from fine dusty seeds - celery, strawberries, petunias, eustoma, lobelia and the like. Small shoots of these plants must be accustomed to the temperature and humidity of the air in the room gradually, so you should not remove the lid from the container immediately after germination of the seeds.

First open it 2-3 times a day for airing for a few minutes, and when the first true leaves appear, cover the container with a lid so that a gap remains all the time. Every day the duration of airing should increase, and eventually the small seedlings will get used to the conditions of the room.

If the container with the crops is covered with plastic wrap, then you can gradually accustom the seedlings to the environment by making punctures in the film with a toothpick. The number of holes must be increased every day.


Immediately after germination, the temperature of the content should be lowered to 18-20 ⁰C. This can be done by rearranging the containers or cups as close to the glass as possible and as far from the radiators as possible. If you have the opportunity, screw on the tap on the battery so that it does not heat up so much, or take the seedlings out to a cool room.


This condition is especially true for those who, like me, sow seeds for seedlings early. I mean additional illumination of seedlings for 12 hours a day. You can illuminate the seedlings with different devices. I have LED bicolor lamps. Since my seedlings will grow on the windowsills before picking, I fixed the lamp on a bent bracket, which my husband made from a long knitting needle. The bracket is clamped between the window frame and the opening part of the window.

The lamp hangs at a distance of 30 cm from the tops of the seedlings, and I can adjust the height if I want. You can improve the lighting by using the reflective effect: I attached ordinary food foil, which is sold in rolls, to the window slopes, and the opening between the window and the room is closed by a curtain made of a foil backing that protects the eyes from red-blue light and reflects it onto the plants.

I want to draw your attention to the fact that all the seedlings are not on the windowsill itself, but on a sheet of foam cut out in the shape of the windowsill, covered with a foil substrate on top. The foam protects the roots of the seedlings from hypothermia, and I use the substrate as an oilcloth in case water suddenly spills during watering.

Watering seedlings

Proper watering is very important for the health of seedlings. In no case should you water the seedlings too abundantly. Allow the top layer of soil to dry out between waterings, and in the root area, the soil should be only slightly damp, but not wet.
Waterlogging has a bad effect on the root system of seedlings: root and root rot can occur, for example, a black leg, from which the seedlings fall and die.

If the soil in the cups is not loose enough and a crust forms on the surface, then between waterings it is necessary to gently loosen it with a toothpick in order to improve air exchange in the seedling cups. After loosening, the water will be absorbed much better, reaching the roots of the seedlings. Watering the seedlings is necessary only with settled water at a temperature of 20-25 ⁰C.

If you create such conditions for them after emergence, the seedlings will grow strong and healthy. And I wish everyone success with seedlings and rich harvests.

How to Grow Great Cucumbers: Secrets of Seedling Care

Every summer resident wants fresh vegetables to appear on the table as soon as possible, and fragrant crispy cucumbers become especially attractive. To get an early harvest of cucumbers, many grow them through seedlings.

Seedlings of cucumbers

However, novice gardeners often encounter difficulties in this matter and instead of strong seedlings they receive painful goners who refuse to bear fruit. Let's take a look at the preferences of this crop and find out how to grow excellent cucumber seedlings.

When to plant eggplants for seedlings

Eggplant is a plant that takes a long time to grow, develop and bear fruit.

This should be taken into account when planting this wonderful vegetable for seedlings.

In Siberia and Central Russia, you can start planting mid-ripening varieties already in early February, and late-ripening ones even at the end of January.

However, before you do this, make sure you can give your seedlings good lighting (up to 16 hours a day).

Since the day is still too short at this time of year, there will not be enough light from the window for seedlings.

Seedlings will lack light, stretch out, and have weak immunity. In this case, you don't have to think about a good harvest.

Use fluorescent lamps or special plant lamps for supplementary lighting.

If you do not have backlighting, we advise you to opt for early-maturing varieties and plant them for seedlings in early to mid-March, when daylight hours naturally lengthen.

Early varieties of eggplants: Alekseevsky, Behemoth F1, Bibo F1, Valentina F1, King of the North, Killer Whale, Quartet, Maxik F1, Gardener's Dream, Lilac Mist, Solaris, Purple Miracle F1, Black Handsome, Nutcracker F1.

Of the mid-season varieties, the most recognized were: Almaz, Swan, Matrosik, Striped flight.

How to prepare a broccoli bed

Well-lit areas are suitable for planting broccoli, where cereals and legumes, cucumbers, and potatoes used to grow. The most suitable soil is loamy, because it retains moisture. The soil for growing broccoli should not be acidic, as this will increase the likelihood of kale attack. To normalize acidity, dolomite flour or wood ash must be added during the preparation of the garden.

Pits for planting broccoli should be made at a distance of 45-50 cm and a depth of at least 20 cm, so that later it would be possible to add soil to the plants. Broccoli loves fertile soil: therefore, put a handful of vermicompost or compost at the bottom of each hole, add a little wood ash and mix with the soil.

Seedling disease prevention and pest control

Only at first glance it seems that there is nothing to fear from seedlings in our apartments and houses. In fact, home conditions are not at all ideal for seedlings of any garden crops. That is why the risk of a black leg in seedlings or the appearance of pests always persists. To prevent the plants from getting sick, it is important to carry out preventive measures. You also need to know what to do if negative changes are already taking place with the seedlings.

Preparing pepper seeds for sowing seedlings

The seeds are sold coated and simple. The pelleted seeds do not require any preparation. They are covered with a capsule, which includes growth stimulants, trace elements, and when soaked, the capsule dissolves.

All other seeds (especially those harvested on their own) need pre-sowing preparation, which includes several stages:

  • the seeds are sorted out, darkened, damaged, empty are removed.
  • soak the seeds in a 3% salt solution, mix and wait 7-10 minutes. Those that float are removed, and the heavy ones that have settled to the bottom are washed and dried.
  • treat the seeds with a fungicide (Fitosporin, Fitolavin, Maxim, etc.) or soak them in a 1% solution of potassium permanganate for 20 minutes. Then they are washed and dried. Such treatment will reduce the risk of fungal diseases on the seedlings.
  • it is useful to soak the seeds in a growth stimulator (Epin - 1-2 drops per 100 ml of water, Zircon - 1 drop per 300 ml of water) for 4-8 hours. Good results are obtained by soaking in aloe juice solution for 20 minutes. (100 ml water and 0.5 tsp aloe juice).

The process of separating full-weight seeds from empty ones

For faster germination, prepared seeds are germinated in a damp cloth in a warm place, avoiding drying out. On days 5-14, the seeds hatch. It is important not to miss this moment, since the root of the peppers is very delicate and fragile, it breaks easily with any manipulation.

On a damp cloth, pepper seeds show "spouts" faster than in the ground

Although this stage of pre-germination is not necessary. You can immediately plant sweet pepper seeds for seedlings in the ground, as with normal sowing.

Temperature in the first week of growing seedlings

As soon as shoots appear (seedling loops), containers with seedlings should be transferred to a cool, but lighted place. The temperature in it should be at the level of 17-18 ° C. Often an insulated loggia or balcony becomes a haven for seedlings. "Climate change" stops the growth of the aerial part, but enhances the development of the root system.

A little "stress" hardens the plant and contributes to better future yields. In conditions of low temperatures, plants are kept from 7 to 10 days.

If you ignore the drop in temperature, the seedlings will rush up sharply, the seedlings will stretch out, be thin and brittle. The optimal temperature conditions during this period are shown in the table:
