Crocuses in autumn: how and when to plant, how to care

Garden plants

In summer cottages, crocuses are one of the most popular spring flowers, although there are species and varieties that bloom by the end of summer. Use these flowers for alpine slides. Crocuses in the flower garden are perfectly combined with other early spring flowers - muscari, primrose and scilla. Crocuses are unpretentious, resistant to natural conditions and reproduce very quickly.
An article about crocus cultivation has already been posted on our site, but today we will tell you about when to dig up crocus bulbs after flowering, where and how to store them, and when to transplant crocuses into the ground in the fall.

When to plant crocuses in the ground in autumn

Landing dates

Crocus planting times depend on what time of year you want to see them bloom. For autumn flowering, the optimal planting time for crocuses is from June to early August. And spring-flowering crocuses are planted before winter.

When to plant crocuses outdoors in autumn? In what month should crocuses be planted so that they bloom as early as possible in the spring? Depending on which area you live in, crocuses are planted from mid-September to early November.

When to plant crocuses in the fall in the suburbs

Crocus planting in the fall in the Moscow region is carried out in October - depending on whether it is early or late, they are planted at the beginning of the month or in the middle. In a warm and long autumn, such as happens in Ukraine or Moldova, crocuses can be planted until the beginning of November.

When to plant crocuses in the Leningrad region

When to plant crocuses before winter in the vicinity of St. Petersburg? In the regions of the Central Russian region, autumn begins at about the same time, therefore, in the Leningrad region, as in the Moscow region, the crocus planting period falls in October, if the weather does not make its own corrections.

When to plant in the Urals

Crocuses are planted in autumn in the Urals during September. And at the beginning, middle or end of the month, it depends on the weather. Crocus bulbs begin their development when the soil temperature drops to 10 ºC.

Planting in autumn in Siberia

When to plant crocuses before winter in more severe climates? Planting crocuses, like tulips, in autumn in Siberia begins at the end of August, but if the autumn is warm, you can postpone the planting to September.

Planting crocuses in the ground before winter

Crocus soil

For crocuses, you need to allocate in the garden a place protected from the wind and well-lit by the sun, where snow does not accumulate in winter - crocuses do not need excess moisture and liquid mud in the roots. They thrive best on light, well-drained, well-fertilized soil.

The autumn planting of crocuses is preceded by the processing of the site: to increase air and water permeability, two weeks before the scheduled time, the soil is dug to a depth of 20-25 cm with humus and river sand, and light soil - with compost. Under heavy clay soils, a drainage layer of fine gravel or expanded clay should be laid at a depth of 20 cm from the surface. You do not need to apply mineral fertilizers.

What depth to plant

Before planting crocuses, you need to determine to what depth to immerse the bulbs in the soil. Like all bulbous flowers, planting depth depends on the composition of the soil and the size of the planting material - the larger the bulb, the deeper the planting hole should be. Large bulbs are planted to a depth of 8-10 cm when grown in light soils and 7-9 cm when grown in heavy soils, and children - 4-5 cm in sandy soil and 3-4 cm in clay soil.

Planting too deep slows down the development of the crocus, but promotes the formation of large bulbs. Sometimes young plants form retracting roots and deepen themselves.

The depth of planting regulates the growth of crocus nests: when the corm is deepened by 5 cm, up to 10 babies can be obtained, with deeper embedding there will be fewer babies, but the crocus bloom will last longer and the nest will need to be divided less often - once every 4-5 years.

How to plant

Make the holes of the desired depth at a distance of 6-10 cm from each other, but if you want to create a thicker mat, the distance between the bulbs can be 3-5 cm.However, it should be borne in mind that the corms are quickly overgrown with children and with such a dense arrangement of bulbs in the ground you will soon have to plant crocuses. After planting, crocuses are watered, but only if you planted them in dry soil.

Crocus care after planting

Crocus care in autumn

For the warm days remaining before winter, the corms should have time to acquire roots. Crocuses do not need fertilizers in the fall, they will only need them in the spring. Crocus watering is carried out when the soil on the site becomes dry, and after watering, the soil is carefully loosened. If weeds appear, remove them, and if heavy rains begin against the background of a cold snap, try to protect the crocus planting from excessive moisture by covering it with a film.

How to care in winter

Many species and varieties of plants are cold-resistant, but some crocuses freeze without shelter in winter. To prevent this from happening, after the first frost, loosen the soil on the site and mulch it with a layer of peat, dry fallen leaves, or cover it with spruce branches.

Transplanting a crocus in the fall to another place

Crocuses can grow in one place for 5-6 years, but it is better to plant them once every 3-4 years. Each faded bulb will give 2, and sometimes 4 bulbs and 5-10 babies for the next season, and if they are not transplanted at least once every 3-4 years, the site will soon overgrow and the crocuses will turn into a weed. When transplanting, crocuses are reproduced. When to replant crocuses - in spring or autumn? Transplanting crocuses in autumn, like planting crocuses in autumn, is carried out at the same time - from September to November.

Corms are dug up in the middle of summer, when the crocuses are dormant. The signal that it is time to remove them from the ground is the yellowing of the leaves of the plant. The corms are cleaned, sorted out, removing damaged or diseased ones, dried in the air in the shade for a week. Then you need to divide the nests: only those babies that easily move away from the corms are separated. All planting material is soaked for half an hour in a dark pink solution of potassium permanganate, then dried and placed in a cool dry place for storage.

When September comes, crocus corms are planted in pre-prepared soil in the order described in our article.

How to store crocuses before planting in the fall

How and where to store crocus corms before planting in the ground? Indeed, from the moment they are removed from the soil until the autumn planting, three months should pass. Disinfected with potassium permanganate and dried corms are laid out in one layer in a wooden box and stored in a room with a temperature of at least 22 ºC until August. From the beginning of August, it is advisable to lower the temperature of the content to 20 ºC, and closer to September - to 15 ºC.

It is in such conditions that Dutch professionals store crocus corms, but since it is difficult for amateur gardeners to organize such conditions, planting material is stored until autumn at room temperature.

Autumn flowering corms are planted in the garden in August, and spring flowering crocuses from September.

Crocuses: planting and care at home

Crocuses are perennial bulbous plants that bloom early and bloom for a short time. They belong to the Iris family and grow up to 25 cm in height. Crocus bloom lasts about 10 days, after which the flowers wither. In mid-June, the leaves of crocuses wilt, and a period of complete rest begins.

Crocus buds can be of different colors: white, yellow, blue, lilac. There are about 100 types of crocuses. The south and east of Europe are considered the birthplace of flowers. They also grow in Asia, Crimea and the Caucasus.

Rules for growing crocuses in a flower bed

  • Seat selection... Crocuses are quite undemanding plants, but if you choose an insufficiently well-lit place for them, then the flowers will be small, and their buds may not even bloom at all. They do not tolerate waterlogged and acidic soils, they suffer greatly from the cold, sharp wind.
  • Flower bed preparation... For autumn planting, the flower bed is prepared in August: they dig it up, if necessary, apply organic and potassium-phosphorus fertilizers. Nitrogen-containing feeding for crocuses is contraindicated at any time. If the soil is too dense, measures are taken to drain it by adding coarse sand.

If you decide to please yourself with the flowering of crocuses in September, then the same manipulations with the flower bed must be done in the middle of summer. Bulb selection... Naturally, before planting, the seed must be carefully examined, to get rid of damaged or sick specimens. Healthy bulbs - be sure to treat with a weak fungicidal solution.

Landing dates... In order for the spring varieties to please you with flowers in April, the bulbs must be planted in August - September.

For a beautiful flower bed in September, plant crocuses in mid-July. Do not purchase already flowering planting material for autumn varieties. Most likely, such plants will not take root at all in your garden. If the flowers wither, then just cut off the dried "tops", and the next year you will get a full harvest. Planting method... When planting crocuses, it must be borne in mind that they look more picturesque in dense groups. But at the same time, we must not forget that during the growing season the plant forms not only leaves and flowers, but also children, for which additional space is needed. Therefore, despite the small size of the corms, they must be located at a distance of about 4 cm.

The planting depth is chosen for small specimens of 4–5 cm, and for larger specimens - about 10 cm. The bulbs must not be buried too deeply, since the roots can pull them even deeper at the end of flowering. Crocus care... Flowers do not require any special activities other than weeding and loosening. It is advisable to feed spring crocuses at the very beginning of the growing season, sprinkling complex fertilizer directly on the snow, and then add urea during flowering. Spring plants do not require additional watering, since after winter the soil is sufficiently saturated with moisture.

For autumn crocuses, watering will not be harmful if the weather is stable. Complex feeding during the flowering period will also be useful for them. Processing and storage of planting material... Crocuses are flowers for lazy gardeners. They do not need to be excavated every year. It is enough to remove the bulbs every 3-4 years for inspection, processing and sorting.

Tubers of early plants are removed from the ground in July, and late flowering ones in early summer. It is necessary to be guided by the fact that the bulbs must spend about 3 months outside the soil before planting. During this period, they are dried, sorted, the damaged areas are sprinkled with ash and sent for storage in a cool place.

The best species and varieties for growing

At the moment, scientists have been able to identify about 80 individual varieties of crocuses, as well as more than 300 varietal crops of this plant. Below will be presented the botanical varieties and crocus varieties that are most often used by gardeners. All crocuses can be divided into just 3 distinct varieties depending on their flowering period.

  • Early spring. This group includes all varieties of saffron, the flowering period of which occurs at the end of winter or the very first days of spring. The species is frost-resistant and usually grows up to 9 cm in height.
  • Spring-flowering or large-flowered. Varieties from this group usually bloom 2-3 weeks after flowering early spring varieties. Such plants are distinguished by a large height of up to 15 cm and contrasting bright flowers of white, purple and blue.
  • Autumn blooming. This includes all varieties of saffron, the flowering period of which falls on September-November. Coloring here can be very different - from white and yellow, to purple with stripes.

Among the most popular and beautiful varieties of crocuses for growing in the garden are: "Ruby Giant", "Blue Pearl", "Princess Beatrix", "Jeanne D'Arc", "Golden Yellow", as well as "Flower Rackord".

How deep to plant crocus bulbs

When creating a voluminous flower bed, plant crocuses at a distance of 5 cm from each other. In fact, experienced flower growers plant bulbs in containers on a flower bed, so they do not "scatter" all over the site and the type of meadow with flowers is well-groomed.

The required planting depth is 3 bulb heights, this is 10-11 cm.It is possible for small bulbs to violate the planting rule, it is better to plant at a depth of 6 cm.

If you live in Siberia or the Urals, then planting crocuses, when setting a constant temperature in the region of -10 ° C, should be covered with spruce branches or fallen leaves. The frosts are bitter there.

Think! Autumn planting of flowers ends in October. There is no point in planting the bulbs later on. Is it worth buying and then destroying the planting material with 100% certainty.

Before the autumn planting, hyacinth bulbs are stored in about the same way as the planting material of other bulbous flowers:

  1. The dug onions are carefully cleaned of the ground and the foliage is cut off with pruning shears or scissors.
  2. Planting material is laid out under a canopy or in a well-ventilated room for drying. The air temperature should be about +18 .. + 22 degrees.
  3. After about five to seven days, the bulbs will dry out. From them you will need to carefully separate the children and clean them of dry scales. Dry roots are cut with pruning shears.
  4. The bulbs are sorted by size and placed in paper bags. If there is a lot of planting material, it is laid out in 1-2 layers in boxes or boxes.
  5. For two months, hyacinth bulbs are stored at a temperature of about +25 degrees.
  6. When 1 month remains before planting, the planting material is transferred to a cooler place with a temperature within +17 degrees.

The air in the room where the hyacinth bulbs will be stored must not be dry, otherwise the bulbs will dry out.

Well-preserved planting material of hyacinths in autumn is planted in open ground as described above.

It is easy to decorate the garden in spring with unusually beautiful and fragrant flowers, if you know when to plant, how, to what depth to plant hyacinth bulbs before winter and how to properly care for plantings in autumn. Beautiful flower beds for you!

When do crocuses bloom?

Spring crocus blooms already in March, breaking through the snow lying still here and there. However, the real splash of crocuses occurs only in April.

Autumn crocus varieties are not as popular as spring ones, although they are striking in their beauty. Planted in summer, they bloom in late September and early October.

Do you already have crocuses in your home or garden? Or are you just planning to plant them?
