Winter growing vegetables, berries, herbs and even mushrooms in the greenhouse is a great idea! If you follow the simple rules of installation and equipment of the room, as well as planting and cultivation of certain crops, you can get several harvests a year.
We have already talked about how to equip a full-fledged winter greenhouse on the site. We talked about how to choose the right heating system to maintain a stable temperature in the greenhouse during the cold months. Today we will help you decide - what exactly can be grown in winter from the garden crops we are used to.
We grow greens in the greenhouse in winter
In the coldest and darkest time of year, the body needs energy replenishment as never before. Of course, you can go for the green vitamins in the supermarket, but why not try to grow much more tasty and healthy fresh greens yourself? It is quite easy!
The vegetation period is not long with it (the guarantee of taking several harvests at once in the autumn-winter season), and the greens are fairly stable to temperature differences (you don’t even need around-the-clock heating in the greenhouse).
Mostly greens in greenhouses are grown not on the main square, but on racks, saving space. With a competent approach to the process, you will not only provide your home with vitamins, but also be able to earn money by selling early greens.
- Early greens for sale - learn to growGreens grown for sale should be bright, healthy and inexpensive. You will be glad to know that this is possible and will take a minimum of time.
Most often in the greenhouse in winter they cultivate:
Bow on feather
For the forcing of a bow and feather, species with a very short dormant period or without it at all (they are ready to form a new crop immediately after harvest) —multiple, batun, shnitt, slizun.
An ordinary soil mixture of peat and garden soil fed with nitrogen fertilizer will be suitable for Luka. The bulbs are cut by the shoulders and soaked for 15 minutes in heated water, then immediately planted in prepared boxes of soil close to each other and watered abundantly.
The first week it is desirable to maintain the temperature in the range of 10-15 ° C, then raise the daily rate to 18-20 ° C. Watering is done as the soil dries. Onions will expel feathers and with natural light, but brighter and denser they will be obtained when illumination with phytolamps.
Cutting the feathers is carried out as needed - under good conditions, you will take off the first harvest in 25-30 days.
Another unpretentious plant for the winter greenhouse - salad. Without much effort on your part (moderate watering, minimal illumination, temperature around 15 ° C), you can harvest its crop every three weeks. The most suitable for such cultivation is watercress.
Rhubarb, chicory, chard and asparagus will also gladly delight you with fresh greens in winter. At the same time they do not even need a lot of light - containers with rhizomes sprinkled with damp earth can be kept on the lowest, low-lit areas of the greenhouse. Crop harvested by cutting off large peripheral leaves and leaving to grow young.
Dill is also a fairly cold and shade-tolerant crop, low-demand to the soil and suitable for winter growing in a greenhouse. It is more rational to use early-maturing varieties for forcing (Aurora, Redoubt, Gribovsky, Grenadier, Far and others), and sowing already germinated seeds in prepared grooves about 2 cm deep.
Dill can be planted on their own or as a sealer for onions or lettuce. Loose, well-moistened soil is desirable for him, temperature not less than 15 ° С and complete absence of drafts are important. Prior to germination, moisten the soil daily with a sprayer, and after watering the seedlings every 5-7 days while the topsoil dries. If you see excessive thickening of the area, carefully thin out the landing.
The first crop of dill you can get in a month or two after sowing the seeds. After a particularly abundant cut, you can feed the remaining bushes with a solution of ammonium nitrate (10 g per 10 liters of water).
This is the most capricious of all the winter inhabitants of the greenhouse, requiring good lighting and a certain thermal regime. Of the two possible methods of cultivating parsley (from root crops or from seeds), we recommend choosing the seed, so there will be less worries.
Like dill, parsley in a greenhouse should be grown from already prepared, hardened and germinated seeds - so you shorten the pre-emergence period, which could otherwise take a month and a half.
Parsley seeds are sown in grooves with a depth of about 2 cm and lightly sprinkled with soil. After that, the seeded area is well moistened with a spray bottle.
In the process of growth, parsley needs a temperature in the range of 12-18 ° C (at higher values, the leaves will turn massively yellow and wither). Also, do not allow overmoistening - watering is carried out only after the topsoil has dried.
Dense shoots should be thinned, before the closure of the rows - regularly loosen and remove weeds.
Once the plants have reached a height of 10-15 cm, you can shoot the first harvest. As in the previous case, if too much green was removed, it is worth feeding the remaining hemp with a solution of urea (a tablespoon per 10 liters of water).
Growing seedlings of vegetables in the winter greenhouse
But to grow seedlings of vegetables your greenhouse should be equipped with a full-fledged heating.
Of course, if your needs for vegetables are small, then a couple of boxes of seedlings can be placed at home on the windowsill. However, if the volumes of vegetables grown are close to industrial ones (for example, you are selling them), you will definitely not have enough space in the apartment - a greenhouse will come to the rescue.
Only self-pollinated plants are suitable for winter growing in a greenhouse!
Cultivation in the winter greenhouse of garden crops differs from their cultivation in the open field, therefore it is important to observe some nuances.
Tomatoes can be planted on seedlings since the beginning of December.
Seeds are sown in boxes with prepared soil, watered with sprinkling and kept under polyethylene until germination (approximately 5-8 days).
Tomato seedlings need regular watering with warm water and mandatory bleaching - the first three days continuously, after 12-14 hours.
The optimum air temperature for growing tomatoes: 24-26 ° C during the day and about 15 ° C at night. After the emergence of seedlings for 4-5 days, they are "hardened" - temporarily reduce the daily temperature to 15-20 ° C, after which they return to the original mode.
Pick up tomato seedlings is carried out in the phase of cotyledons. After two weeks, it is worth feeding the plants with complex mineral fertilizer (1 tsp. Per 5 liters of water). After another 2-3 weeks, fertilize again (0.5 tsp. Superphosphate + 0.5 tsp. Potassium sulphate per 5 liters of water).
From time to time, growing plants in pots are moved so that the leaves of neighbors do not shade each other.
In February, tomato seedlings can be planted in the beds, not forgetting to tie up the stems vertically. Watering is done at the root, stepchildren are removed. When the plant reaches a height of one and a half meters, it is pinned to the top and cut off the leaves that grow below the resulting fruit.
Starting from the first days of January, you can already plant cucumbers on the seedlings in the winter greenhouse.
- Review of greenhouses for cucumbers (with photos)Choosing a greenhouse for cucumbers depends on several factors, primarily on the climate in the region. What is the difference between different types?
Sprouted cucumber seeds are sown in pots (ideal - peat) with prepared evenly moistened soil and cover with a film before germination (about 5-6 days). Reproduction is done 10-12 hours per day.
The temperature suitable for growing cucumber seedlings is about 23 ° C during the day and 17-18 ° C at night. After the emergence of the seedlings, they are “hardened” in the manner described above, reducing the daytime temperature to 15–20 ° C for several days, then raising it to its former level.
Feeding cucumbers is also produced twice - with complex mineral fertilizer in the formation of two true leaves (1 tsp per 5 l of water) and 10 days after that with a mixture of 20 g of potassium nitrate, 30 g of ammonium nitrate and 40 g of superphosphate (all this 10 liters of water).
Seedlings are planted in beds in February with a distance between plants of about 40 cm (planting depth - up to the cotyledons or the first pair of true leaves) and tied to a trellis. Watering requires regular, moderate, the soil should be loose.
If you grow several crops in a winter greenhouse, make sure that tomatoes and cucumbers are not neighbors, they do not like this very much.
Eggplants are planted on seedlings in the winter greenhouse at the very beginning of February.
Eggplant seeds are sown in boxes with prepared soil, sprinkled over and kept under covering material until germination (approximately 10-14 days). Eggplants are added about 12 hours a day.
Before the emergence of shoots, the temperature in the greenhouse is maintained at 20-25 ° С during the day and about 12-15 ° С at night. After germination, they are quenched in the manner described above. Humidity in the room is maintained within 75-85%.
Instead of picking, eggplants in phase 1-2 of these leaves roll over into larger containers, taking care not to damage the roots. Then the plants should be fed - 10-15 days after transshipment and then every two weeks (mineral fertilizers alternate with organic matter, the type of fertilizer is the same as for cucumbers).
The deadline for planting the stunted plants of eggplants in beds is April. They need regular watering and loosening the soil. The main stem of the plant should be tied to the trellis, and pinch the top.
Pepper, as well as eggplants, are planted on seedlings in the winter greenhouse in early February.
Pepper seeds are sown in a container with prepared soil, watered with sprinkling and kept under the film until germination (about 3-6 days). Supplement is made 10-12 hours a day.
Before the plants hatch, the air temperature is maintained at 22-26 ° C during the day and about 15-18 ° C at night. After germination, they are quenched and watered as described above.
Just like eggplants, sweet peppers do not dive, but roll over along with a clod of earth so that the sheet remains above the surface at a height of at least 1 cm. Feeding after this (fertilizers similar to those used for cucumbers) is carried out twice - through 2-3 weeks after transshipment and with the appearance of 4-5 leaves.
Pepper plants are planted in the ground in April. Further care is to timely watering (make sure that the water does not fall on the leaves) and loosening the soil, as well as mineral fertilizers 1-2 times a month.
Of course, this is not all crops that can be grown in a winter greenhouse. Also suitable for this zucchini, potatoes, carrots, radishes, strawberries, raspberries and even grapes with melons. However, for the beginning, we advise you not to threaten grandiose plans, but to master more unpretentious and less labor-intensive cultures.
