When the year begins, the vegetable garden seems to be on pause, as if everything were waiting for the good weather of March or April. However, Winter is the perfect time to sow many vegetables and get everything ready so that spring bursts into greenery In a matter of weeks. If you play your cards right, as soon as the temperatures rise a little, your pantry will be overflowing.
Although many of these plants withstand the cold quite well, Frost remains the main enemy during these monthsI'll tell you which 8 seeds are worth planting now for a quick harvest, and we'll also look at a good number of autumn and winter crops, how to protect them from frost, how to organize an urban garden on a terrace or balcony, and which associations and rotations work best to keep the soil fertile for many years.
Why sow in winter to harvest quickly in spring
Sowing seeds in the dead of winter might sound strange, but Many vegetables need to go through low temperatures to grow compact, sweet and tastyRoot vegetables like carrots or beets even improve their flavor after a few light frosts.
Also, if you start now, You take advantage of a few months when the garden is usually half empty., you leave the land occupied (which hinders the appearance of spontaneous weeds) and stagger the harvests so as not to have everything ready at once.
However, in winter you have to water with caution. On frosty days, it is advisable to reduce watering considerably so that the water in the substrate does not freeze. and damage the roots. A very effective trick is to protect the soil with mulch made of straw, dry leaves, or a good layer of worm castings.
This padding helps to the ground maintains a somewhat more stable temperature and retains moisture much better, something crucial when cold winds quickly dry the earth's surface.
The 8 key seeds you should plant in winter
Among all the autumn and winter vegetables, there are 8 that, when sown in the colder months, They offer an ideal combination of speed, ease of cultivation, and abundant harvest just as spring approaches.These are: peas, broad beans, carrots, radishes, lettuce, spinach, chard, and onions.
Later on we'll see many more crops, but if you're starting out Or if you don't have much space, focusing on these eight guarantees quick results. and a very productive garden.
1. Peas
Peas are a legume that many people mistake for a vegetable, but They are actually one of winter's best allies because they withstand the cold and fix nitrogen in the soil.They can be sown from late summer to mid-autumn, and in many areas also in mid-winter if there are no extreme frosts.
The soil should be somewhat silty, well aerated and with decent drainage. Sow the seeds in rows, leaving about 15 cm between plants.at a depth of about 3-4 cm. Climbing varieties need supports (canes, netting or branches) to climb.
Peas don't like waterlogged soil: Water thoroughly but infrequently, allowing the soil to breathe between waterings.In 60-90 days, depending on the variety and climate, you can start harvesting the first tender pods.
2. Broad beans
Broad beans are another classic for autumn and winter. They can be sown from September until well into Decemberbecause they tolerate the cold better than it seems, as long as the frosts are not extreme and continuous.
The sowing is done directly, “by hits”: In each hole, 3-5 cm deep, place 3 seeds, separating the holes about 40 cm apart.When they sprout, leave only the most vigorous plant in each group and hill it up (add soil around the stem) to give it more stability.
They prefer moderate and regular watering, avoiding at all costs Avoid excessive water during peak flowering because it can cause many flowers to fall off and reduce the harvest.They are not demanding in nutrients and even improve the soil as a good legume crop.
3. Carrots
The carrot is an all-rounder: It can be sown almost all year round, although it is especially comfortable in cool temperatures and light frosts.It germinates more slowly in winter, but the flavor and texture of the roots more than make up for it.
It needs a deep, loose, stone-free soil with a silty-sandy texture. Make furrows 1 cm deep and distribute several seeds every 2-3 cmbecause not all of them germinate. Then thin them out to leave about 7-8 cm between plants.
The key to carrots is moisture: The substrate must maintain a constant and somewhat deep moisture.Simply wetting the surface isn't enough. In 70-90 days you'll have good-sized roots, and you can harvest them gradually as you reach the desired thickness.
4. Radishes
If you're impatient, radishes are for you. They are among the fastest-growing crops in the garden: you can be eating them in about 4 weeks.and in winter they develop larger, juicier roots.
They are sown directly in the ground, at a depth of 1-2 cm, with a separation of 3-5 cm. Ideally, a new row should be sown every 10-15 days. to have radishes continuously.
They are not fussy about the soil or fertilizer, but they are about the water: If there's not enough water, they become fibrous and spicy, and if you overwater them, they become hollow and split.They are perfect as a secondary crop between rows of other longer-cycle vegetables.
5. Lettuce
Lettuce is another essential ingredient in the winter garden because It withstands the cold very well, but in the heat it bolts and becomes bitter quickly.. There are many varietiesRoman, loose-leaf, buds, oak-leaf type, etc.
You can sow it in a seedbed and transplant it when it has 4-5 true leaves, or do direct sowing and then thin it out. The planting distance is usually between 20 and 30 cm, depending on the size of the variety.
Their cycle is short; they are usually ready in 5-10 weeks. It thrives in pots and raised beds.And you can cut only the outer leaves on cutting varieties, letting it regrow again and again.
6. Spinach
Spinach performs especially well in cold weather. Autumn-winter varieties are sown between September and October, but in mild climates you can extend sowing throughout much of the winter..
Direct sowing is usually done in rows spaced 20-30 cm apart, at a very shallow depth (1-2 cm). Afterwards, thinning is done to leave about 10-20 cm between plants. After 5-6 weeks you can start harvesting large leavesor cut the whole plant as you see fit.
It's quite demanding in nitrogen, so It is advisable to fertilize the soil with well-decomposed compost before sowing.It requires frequent but small amounts of watering to keep the soil always cool.
7. Chard
Chard is another very rewarding biennial crop that You can have it in the garden practically all year round.provided you choose the right variety (there are spring and autumn varieties).
It is not very fussy about the type of soil, although it appreciates that it is loose and rich in humus. It can be sown directly during almost any monthBut in winter it will need some protection in areas with severe frost.
The seeds germinate in 10-15 days. In about three months you can start cutting the outer leaves.And the plant will continue to produce for a long time. It loves water and responds well to mulching to retain moisture.
8. Onion
Onions are very typical of this time of year. It is usually started in a seedbed in late autumn and transplanted in late winter or early springAlthough you can also plant purchased seedlings to save time.
It doesn't need large amounts of water, but Watering should be regular, especially while the bulb is forming.Towards the end of the cycle, watering is spaced out to allow the plants to dry well and be better preserved.
Onions are hardy and quite undemanding; they grow well even in deep containers. It is a magnificent companion plant for lettuce, carrots, tomatoes, cucumbers or radishesand it is advisable to avoid associating it with legumes such as peas and broad beans.
Other winter vegetables worth knowing about
In addition to these eight winter stars, there is a whole catalog of crops that You can keep it running during the colder months to make the most of the space.Many of them combine very well with each other and allow harvesting almost all year round.
Cruciferous vegetables: cabbage, broccoli, cauliflower, Brussels sprouts and red cabbage
Cruciferous vegetables (various cabbages, broccoli, cauliflower, red cabbage, Brussels sprouts…) They are the queens of the cold and fear the summer heat much more than winter.The important thing is that the bud or inflorescence formation phase does not coincide with sweltering months.
They are usually sown in seedbeds and transplanted when they have 3-5 true leaves. They need fertile, deep soils with good moisture and rich in organic matterAs they are large plants, they are usually planted with frames of 50×50 cm or more.
They benefit greatly from mulch to retain moisture, and in tall varieties it is recommended to reinforce the stem with soil to prevent them from falling over. They are very commonly associated with short-cycle crops such as spinach or lettuce to take advantage of the gaps while they grow.
Among its main problems are aphids, cabbage butterfly, cabbage fly and the famous clubroot (a fungus that deforms roots). Rotating crops properly and combining them with aromatic plants like mint, rosemary, or thyme helps a lot in preventing pests..
Endive and other salad leaves
Escarole is perfect for those who want winter salads with a more intense flavor. It withstands low temperatures better than high temperatures and it thrives with contrasting cool days and cold nights.
There is a wide variety of types (broad leaf, curly leaf, thin leaf, etc.). It needs a floor that maintains some internal moisture but with a relatively dry surface. to avoid neck rot, and watering preferably in the morning or at dusk.
To achieve a white and crispy center, blanching techniques are often used: Tie up the outer leaves, place opaque plastic tubes or tunnels over the plant or cover with black plastic for a few days before harvesting.
Celery
Celery tolerates the cold quite well, although with extremely low temperatures it tends to flower prematurely. Its germination is slow and it requires consistently moist soil.Therefore, irrigation cannot be neglected.
It is a thirsty crop that prefers to be in cool soils with good organic matter. It's not advisable to plant it next to carrots or parsley, as they share a family and problems.But it goes well with onion, garlic, or lettuce.
Turnip and beetroot
Both turnips and beets are excellent cool-weather root vegetables. Turnips are usually sown in late summer and autumn to be harvested in winter.while some early varieties are harvested in spring and summer.
Turnips don't tolerate heat or drought well, so It appreciates some shade from taller plants and regular watering.Autumn and winter varieties are sown in midsummer to be harvested in the cold season and can be stored well in dry sand or straw.
Beetroot, for its part, It is surprisingly resistant to both cold and heatHowever, it achieves better quality when the growing season is relatively fresh. It prefers medium soils, rich in humus, with moderate but frequent watering and fairly constant moisture.
It is sown directly in the ground, because Its "seed" is actually a fruit with several seeds inside.Once the seedlings emerge, thin them out, leaving only one at regular intervals. In 2-4 months, depending on the climate and variety, you'll have roots ready to cook, roast, or even eat raw.
Leek, garlic and other lily family
Leeks are a fantastic all-rounder for long-cycle crops. It withstands the cold very well, adapts to many climates, and can be harvested little by little.for months.
It is sown in seedbeds between February and autumn, and transplanted when the seedlings are about 15-20 cm tall. It likes loose soils, rich in humus and with good regular moistureSometimes it is piled high with soil to further whiten the stem, but it is not essential.
It pairs wonderfully with carrots, because Leeks help repel carrot flies, and carrots repel leek worms.However, it doesn't get along as well with beans, peas, cabbage, or beets.
Garlic, meanwhile, is one of the great classics of the cold season. It can be planted in autumn or in the first months of winterDepending on the weather and whether we want fresh garlic or dried garlic to store.
The teeth are buried about 2,5 cm deep, with the point facing upwards, leaving about 15 cm between them and 30 cm between lines. It loves direct sunlight and fertile but well-drained soil.Constant humidity helps the bulbs to grow, but excess water causes fungal diseases.
Arugula and lamb's lettuce
Arugula and lamb's lettuce are ideal leaves to add variety to winter salads. Arugula prefers mild temperatures and does not tolerate extreme heat well.which makes it sprout and makes the taste too bitter.
It can be sown from late winter to autumn. It has a short growing cycle and Tender leaves can be cut in 4-6 weeksIt tolerates partial shade well, so it works great alongside tomatoes, peppers, or eggplants with a longer growing cycle.
The canons, for their part, They really appreciate the humidity and the cool airThey are sown in late summer and autumn, in fairly firm soils free of weeds. It is advisable to keep the land free of weeds and to thin the plants if the sowing was too dense.
Winter aromatic and medicinal plants
To complete the winter garden, you can include some hardy aromatic plants which, in addition to adding flavor, They help repel pests and attract pollinators when they bloom.Among those you could grow are:
- Mentawhich prefers cool and somewhat damp soils.
- Marigold, very rustic and known for its medicinal properties.
- Borage, a traditional plant in many areas, with edible leaves and flowers.
Borage, for example, It can be planted in winter and summerAlthough it tends to bolt in warm weather. In winter it grows more slowly (3-4 months), but produces excellent tender stems for cooking, and its blue flowers are highly prized in infusions.
How to set up and care for an urban garden in winter
You don't need a huge farm to enjoy these vegetables. A small patio, a terrace, or even a well-oriented balcony is enough to set up a home garden. that will supply you with fresh leaves, roots and herbs all winter long.
Choosing the place and the containers
The first thing is to choose a place with as much direct sunlight as possible. Ideally, plants should receive at least 6 hours of sunlight per dayAnd in winter, a northeast or south orientation is usually the most favorable.
If horizontal space is limited, you can resort to vertical solutions: wall gardens, shelves, pallets, hanging plantersetc. Here, lettuce, endive, parsley, arugula, small-leaf chard and aromatic herbs such as thyme, oregano, sage or lemon balm work wonderfully.
As for containers, you can reuse almost anything (drawers, large bottles, raised beds, wooden boxes…) as long as Make sure they have good drainage at the base so that excess water can drain away.For deep-rooted crops such as carrots or leeks, pots 30-40 cm deep are best.
Substrate, sowing and irrigation
The substrate should be fertile, spongy and well aerated, with a good capacity to retain water and nutrients. You can mix old soil with worm castings or mature compost and some sand to improve the structure and drainage.
They are used in urban gardens two types of planting:
- Direct sowing, ideal for large seeds and those sensitive to transplanting (carrot, radish, spinach, pea, broad bean, corn, pumpkin, etc.).
- Sowing in seedbed for small seeds or crops that appreciate a protected environment at first (tomato, pepper, eggplant, broccoli, cauliflower, lettuce if it is very cold, etc.).
Regarding irrigation, plants consume less water in winter, but Cold winds and sunny days can dry out the substrate more than necessary.The best time to water is in the morning, so that the plants spend the night with less waterlogged soil and to avoid fungus.
Crop association and rotation
A simple way to have healthier plants and make better use of space is to practice companion planting. Some vegetables help each other because they share water and nutrient needs or because they protect each other from pests..
useful examples in winter:
- Lettuce with onion or garlicThe leaves grow quickly and leave space when harvested, and lilies help repel certain pests.
- Radish with carrot and spinachThe radish is harvested in a month, long before the others take up the space.
- Broccoli or cauliflower with lettuce or spinachThe cabbages need more time and the short-cycle leaves fill the gaps in the meantime.
Rotation is also key: It is not advisable to plant vegetables from the same family in the same place for at least 3 years. (cruciferous plants, nightshades, lilies, legumes, etc.). This prevents soil depletion and significantly reduces specific diseases.
Protection against cold, frost and pests
In winter, in addition to the cold, fungi and some typical pests that hibernate in the garden appear. Protect plants from frost with plastic tunnels, thermal blankets, or even recycled bottles used as mini-greenhouses can make a difference.
Mulching with straw, leaves, or shredded pruning debris helps maintain root temperature, but it also It can serve as a refuge for slugs and snails if the climate is very humid.So it's a good idea to keep an eye on them and set traps (for example, containers of beer buried at ground level).
Aphids, whiteflies, leafminers, and thrips also attack in protected environments. Control nitrogen inputs, promote ventilation, and use preparations such as potassium soap or nettle manure. This is usually enough to keep them under control in a home garden.
If you maintain a certain consistency in watering, check the plants frequently, and respect crop rotations, Your winter garden will become the best foundation for an explosive spring harvest.With these 8 key seeds combined with the rest of the autumn and winter crops, you can have sweet roots, tender leaves and fresh aromas practically all year round.
