Preparation, germination, planting of dahlia tubers: instructions for growing healthy flowers

Planting and caring for dahlias

Dahlias are planted in open ground in May. Focus on your climate, if you live in warm southern regions, then you can land earlier, if in the middle zone or Siberia, then at the end of May, when stable warm weather sets in.

Dahlias are thermophilic, they cannot stand the cold, and will not withstand frost. Be prepared to cover them with spabond if it gets colder.

Planting without germination

Indeed, if in May you purchased a dahlia tuber, then it can be planted immediately, without preliminary forcing, special germination and growing at home.

As a rule, at this time the dahlia root already has distinct sprouts or at least "eyes". The only pre-planting preparation in this case is the removal of wilted, rotten parts and old thin roots, soaking the tuber in water for several hours so that it is saturated with moisture, and treatment with a weak solution of manganese or fugnicide just before planting.

Dahlias prefer well-lit areas and nutritious soil. For planting, you need to dig a wide hole so that the dahlia roots fit freely there. We plant sprouts towards the sun.

Gardeners with many years of experience advise not to stop your attention only on the correct pinching of the dahlia.

For the comfortable existence of a plant, it is important to follow all the rules of agricultural technology. This is the correct planting, watering, feeding and, of course, the formation of the bush.

Germination technologies

After the planting material was taken out of the cellar and measures for cleaning, sanitizing and dividing the tubers were carried out in relation to it, it is time for the direct germination of dahlias. For this, wide drawers of shallow depth are used. Separate "potato" dahlia are laid out in a prepared container and sprinkled with sawdust, peat or loose earth. The top layer is well moistened. If all conditions have been met, the tubers will sprout within 6-7 days.

Important! The root collar of tubers should not be covered with earth, as dormant buds may be on it. This part of the tubers should protrude above the soil surface - so the "dormant" buds will sprout faster .. During the daytime, boxes with germinated dahlias are recommended to be taken out to a warm, bright place

For these purposes, a greenhouse or veranda is perfect. At the same time, protection from direct sunlight must be ensured - otherwise, still very small sprouts risk getting burns

Germination in trenches

This method of sprouting dahlia tubers after winter is used when there is no room for boxes in the house or on the site. In this case, a pit of a certain length is dug on the site, 1 bayonet deep and two bayonets wide. At the bottom of the pit, pre-prepared tubers, pre-divided and cuttings, are laid. Different varieties are marked with tags or pegs.The material for planting is covered with a layer of earth, metal-profile or plastic arcs are mounted above the trench, onto which the film is subsequently stretched. Outwardly, the finished structure looks like a greenhouse. To ensure good insulation, the edges of the film are fixed with a load: earth, bricks or wood scraps. There is no need to water the trench, since in the spring the soil is saturated with moisture. The first green shoots will begin to appear after 2 weeks. After this time, it is allowed to open the film during the day, so that the sprouts are hardened and receive a sufficient amount of sunlight.

Preparing tubers before planting in bags

This option is suitable when there is nowhere to get dahlias for germination in the spring due to lack of free space. Germination of tubers in packages also involves preliminary preparation: cleaning, dividing and grafting. The starting date of the event is 2 weeks before the scheduled disembarkation date. Cellophane garbage bags are recognized as the optimal packaging. After preparation, the tubers are packed in bags. If the planting material is a little dry or wrinkled, it can be lightly sprayed with water. Moisture will also help the buds to "wake up" and will further promote good sprout stretching. Packages with dahlia tubers packed in them are placed in a dark and warm place for up to 10 days. After the expiration of the indicated period, the plastic bags must be opened and the tubers must be sprinkled with water again. In another 7-8 days, the material will be ready for planting.

Dahlia tubers for germination and cuttings, do you need light?

I get dahlia tubers from the basement at the end of April, they are just starting to sprout. Store in a cool dry place, they are afraid of frost.

can be germinated on a damp substrate. better diffused light and warmth. when eyes appear, they can be divided and planted in pots and grown in the light. I do not think. that there is a big tuber. therefore, you can immediately plant it shallowly in a pot. so that the neck is visible and grow. some shoots can be taken for rooting and side shoots from the axils of the leaves too. they are formed if the top is trimmed. so that they are not too high. A greenhouse is not needed for a tuber. but for cuttings it is needed.

Planting dahlias outdoors and caring for plants

The timing of planting dahlias in open ground depends on the climatic conditions of the area. In the middle lane, dahlias are planted in open ground after June 1-10 with grown plants. Dahlias can be planted earlier, as soon as the soil warms up enough, from about May 15-20, unforgiven divided tubers with pronounced eyes. After two weeks, shoots appear from the ground. It is necessary to monitor the air temperature and cover the plants if there is a threat of frost.

Some growers plant grown dahlias in the ground ahead of schedule to get early flowering of dahlias. In this case, prepare shelters from frost

Planting of plants (both cuttings and those grown from divided tubers) is carried out in pre-prepared areas with spaced stakes and holes dug around them.The approximate distance between plants is set at half the height of an adult plant (from 60 to 100 cm in a row), the distance between rows is at least 100 cm. Stakes must be strong, 160-180 cm high. Coniferous stakes are more durable.

For their long-term preservation, it is necessary to soak the lower part of the stakes with special compounds, for example, 7% iron sulfate, and paint the stakes themselves with green paint. More durable and comfortable metal stakes. To do this, use old unusable pipes or pieces of reinforcing steel with a diameter of 12-20 mm. The stakes are driven to a depth of 40 cm. After that, a plant is planted closer to the stake (with water added to the hole) so that the tuber neck is 4-5 cm below ground level.

Cuttings and hybrid seedlings are usually planted deeper, up to 8-10 cm. Cutting plants are best planted with two plants under each stake. In this case, it is imperative to take into account the growth of plants. When planting dahlias on beds in two or three rows, they try to select plants by growth. In the first row, low ones are planted, in the second - of medium height, in the third - high and very tall varieties, while the shape, color and size of dahlia inflorescences are also taken into account.

It is recommended to plant plants in cloudy weather or in the evening.

Cutting plants or plants grown from divided tubers are spilled heavily with water before planting, and then carefully, trying not to damage the plants and not break up the clod, with a lump of earth, are planted in a prepared hole. Around the planted plants, ring-shaped holes are made or the holes are left incompletely covered to ensure the convenience of watering

In the future, when processing the soil, the hole is gradually leveled, and furrows are made for irrigation. The planted plants are immediately tied to stakes (depending on the height of the plant in 2-3 places or more). As the plants grow, the garter is continued. Immediately upon planting, a label is attached to the top of the stake with the name (or number) of the plant.

In the following days after planting, it is necessary to water the plants regularly and abundantly. The frequency of watering is regulated depending on the temperature and humidity. In dry and hot weather, watering in the first week after planting is carried out daily, later less often, but in such a way that the soil under the dahlias always remains moist. Lack of moisture, especially in dry hot weather, leads to slower growth, woody stems, deterioration of flowering and loss of decorativeness of dahlias, which usually recovers slowly only with the onset of cooler and rainy weather.

The land under the dahlias must be maintained at all times in a loose state, free of weeds. Usually, loosening is done after each watering or top dressing (liquid or dry). After the formation of buds and the closure of the green mass of plants, loosening stops. It is recommended to mulch the soil with humus or peat after the cessation of loosening. Mulching protects the soil surface from crusting, retards the development of weeds, and allows you to reduce the number of watering.

In early September, before the onset of autumn frosts, it is recommended to check the presence of labels and the correctness of the name of the dahlia varieties, to enter a brief description of the variety in the journal (if you have not done this earlier). With the onset of cold weather, you need to spud the dahlias. With deeper planting, hilling can be omitted. Hilling protects dahlias from the first autumn frosts. The hilling height should be 15-20 centimeters.

Dahlia bush formation

For dahlias grown from a tuber, it is recommended to leave no more than two shoots, the strongest, all the rest are removed as early as possible.In cuttings plants, as a rule, one stem is left, but sometimes, to give splendor to the bush, pinch the top of the plant above the third node, while the plant develops into two stems.

In large-flowered varieties of dahlias, to increase the size of the inflorescences, all lateral shoots that appear from the axils of the leaves are removed - the so-called stepchildren. If you leave all the stepchildren developing on the stem, especially in its lower part, then flowering slows down and decreases, the size of inflorescences decreases. Therefore, they should be removed at the very beginning of appearance and as close to the stem as possible.

In addition, the lower shoots are often broken off from the main stem, which increases the possibility of spores of parasitic fungi entering the affected areas, and this can lead to the death of the entire terrestrial part of the plant, especially in wet rainy weather. Dahlias need to be grown regularly, starting from the moment they are planted in open ground and until buds appear in the leaf axils of the main stems. As a rule, all stepsons are removed up to the internode preceding the node with buds.

Pompon, collar, dwarf and all small-flowered varieties of george are not pinned.

In many varieties of dahlias, due to the peculiarity of their budding, it is necessary to remove not only lateral shoots, but also extra buds, especially when dahlias are grown for cutting or for demonstration at exhibitions. Usually, dahlias on a flowering shoot form buds in groups of three, of which the middle bud develops faster, but it often has a shorter peduncle, sometimes not very suitable for cutting.

In such cases, the middle bud must be removed, then the lateral buds grow longer peduncles with lush inflorescences. In dahlias of powerful development, regardless of their height, in addition to the stepsons, part of the lower leaves is removed if they cover the root collar. This promotes better ripening of the tubers and prevents a strong thickening of the trunk.

The formation of the bush begins after the appearance of stepsons or pinching the top after the fourth pair of leaves.

To obtain undersized dahlia bushes, the tubers, divided into parts, are planted in pots with nutritious soil at the end of February and placed in a bright place with a temperature of 15-20 ° C. When shoots appear, the strongest are left (one or two), the rest are broken into cuttings. When the fourth pair of leaves appears, the top is pinched, two stems grow, and above the second pair of leaves on these stems, the top is pinched again, from one or two initial stems, four or eight have already developed.

With this formation, the height of the bush usually does not exceed 1 m, although its varietal feature is a height of more than 160 cm. Plants are formed in the same way for exhibitions. Grasshopping is carried out in the usual way, like in other plants.

In the process of flowering, dahlias on the bush appear faded inflorescences that have lost their decorative effect. They spoil the beauty of the bush. Such inflorescences must be removed daily.

Preparing dahlia tubers for planting

• The preparation of planting material begins in late March - early April when planting dahlias with seedlings.
• If it is decided to plant the tubers immediately in the ground, then the preparation is carried out two weeks before planting - in the first half of May.

We take out the dahlia tubers from the storage area and carefully examine them. It is necessary to remove all dried roots and nodules, cut out the rotten parts. Treat all cut points with brilliant green or sprinkle with ash, crushed activated carbon.

These tubers must be divided into sections with 1-3 tubers.

If the rhizomes were not divided in the fall, then this must be done before planting.Why share? A large tuber with a large number of buds will produce a thickened plant that will shade itself and bloom poorly. This is especially true for large-flowered tall varieties. Tubers of low-growing curb dahlias do not need to be divided before planting.

If the buds on the root collar have not yet woken up, the tubers should be placed in a bright, warm place. As soon as the sprouts hatch, you can start dividing.

Dividing dahlia tubers.

With a sharp knife, starting from the hemp, it is necessary to carefully cut the root tubers so that the resulting divisions are with a root collar and have 1-3 points of growth. One cut can contain 1-3 nodules. Sprinkle the cut points with ash or crushed coal, grease with brilliant green.

For planting tubers, the resulting cuttings are placed in boxes or transparent bags with openings for air access and lightly sprayed. This is done two weeks before planting. In a bright, warm place, the buds will quickly wake up and sprouts will hatch. The tubers are ready for planting.

We grow seedlings

Growing seedlings is used to obtain an earlier flowering.
We plant the resulting cuttings in small plastic containers or pots, in which there must be drainage holes. We use light soil: coconut substrate, sand, sawdust, light earth.

We fill the tubers with the substrate so that the root collar with the buds is on the surface. This planting will protect the root collar from decay.

Growing dahlia seedlings

Seedling care: The place for seedlings should be light, but direct sunlight is detrimental to tender sprouts. The optimum temperature is 15-18 degrees. Watering is minimal. Top dressing is not needed, since there are enough nutrients in the tuber, which will be enough before planting seedlings in open ground.

Cannes can be dripped into a box at home for a long time, they have a very long growing season - otherwise they will not have time to bloom. Gladioli, a month before planting, clean and put in a box for germination just in the room. Dahlias can be obtained, if this has not been done before, in order to control the quality of tubers - to remove rotten parts, dried up, you can treat with something disinfecting. If there is no desire to plant for early flowering, then put it away for further storage. You can get it for germination in May. You will divide the dahlias when the buds are visible, so that there is at least one on each divide. Cannabis dahlias are planted in the ground when the threat of frost has passed. Gladioli are like potatoes when the ground warms up at a depth of about 15 cm.

How to prepare dahlias for planting

Dahlias belong to the family of Compositae plants and have 15 varieties that are grown in the form of cultivated plants in personal plots, in summer cottages and in city flower beds in the form of compositions with other flowers. Dahlias can have the most varied color and shape of inflorescences, pleasing to the eye for 3 months, that is, almost the entire summer season.

Instructions

• Also, dahlias are great in vases, with proper care - up to 1 month. To plant these beautiful flowers, the tubers must be properly prepared after winter storage.
• To prepare tubers for landing remove the boxes from the basement where they were stored all winter. Inspect all planting material carefully. Cut off all affected and rotten places with a sharp knife and process the cuts with wood ash or brilliant green. You can also carry out processing with a weak solution of potassium permanganate, dipping the tubers for 30 minutes in a pink solution.
• Place the tubers in boxes, cover with soil and slightly moisten the soil. This will allow germination and cuttings for faster germination, since dahlias are planted in open ground after the threat of freezing has passed. But when sprinkling the tubers, do not forget that the upper part should protrude at least 3 cm above the ground. If you apply a deeper powder, the neck of the tubers will begin to rot, which will lead to complete damage to the entire tuber.
• Boxes with tubers can be placed in a greenhouse or taken out to the site for the whole day in stable warm weather, but at night they will have to be brought into the house or covered with dense material.
• When transplanting into the ground, follow the same rule - do not deepen the germinated dahlias too much.
• The second method for preparing dahlia tubers is that planting is used without prior germination. To do this, one week before planting tubers in open ground or under a film shelter, remove them from the storage, inspect, remove all rotten places, treat with wood ash or brilliant green, take them out into the open air in boxes. Moisten the tubers slightly by spraying. Spray daily.
• After 7 days, after the tubers get used to the light a little and are saturated with moisture, plant them in a permanent place.
• Planting without germinating dahlias 10 days earlier than with the preparation method with germination.

Tuber preparation

Depending on whether you got the dahlias from the underground or bought in the store, there are features of their preparation for landing in the ground. During winter storage, tubers usually dry out, some of them show signs of disease. In order for dahlias to sprout well in the future and bloom together, they must first be germinated correctly so that the dormant buds wake up during storage.

Having taken out tubers from the basement, the cellar, they are left for 2-3 days in a cool, and then warm room, so that the plant gradually adapts.

The benefits of dividing tubers

Dahlias are a corm plant that produces many tubers every year. So that the dahlias do not thicken, in the fall, after digging from the ground, they are divided into several parts. Or it is done in the spring shortly before planting in the ground. Many people may have a question: why divide the tubers, they will still grow and bloom anyway?

When there are many shoots from one hummock, the growing stems will shade themselves. And planted in one hole, they take a lot of nutrients. A large number of stems will result in poor flowering. If the bush is not divided, then some of the buds coming from the bottom did not have the strength to break through to the top. They will simply perish and not rise. Hoping for more flowers, there may actually be much fewer flowers and the flowers themselves will not be as large.

Planted in small bumps, the plant will receive a sufficient amount of nutrition, thereby the stems become more powerful and more flower stalks will grow on them.

How to properly divide tubers

They start dividing when small sprouts have appeared. Know that when large sprouts grow, there is no longer any point in dividing, because after dividing the plant will hurt, even die, and flowering occurs much later.

Tubers are first separated by hand carefully. And then cut with a sharp knife along the root collar so that only 1-2 sprouts and 2-3 tubers remain for planting

This is the best option for planting. On the divided parts, a dry stem, thin roots, dried and diseased tubers are removed. Allow the cut areas to dry for a few minutes. Then the places of the cuts are treated with brilliant green.You can powder the sections with crushed charcoal, ash, or crushed activated charcoal tablets to kill any remaining fungal spores and bacteria. For disinfection, tubers are soaked for 30 minutes in a weak solution of potassium permanganate, ready-made fungicides, in phytosporin. The disinfected tubers are washed with clean water and allowed to dry.

Sprouting tubers

For germination, it is not at all necessary to use nutrient soil. For this purpose, use

• coconut extract,
• wet sawdust,
• vermiculite,
• river sand.

A substrate is poured onto the bottom of the container with a layer of 2-3 cm, moistened, if it is dry, the tubers are placed on top. The substrate is again poured on top so that the buds are on the surface of the soil or flush with it. Germinated at room temperature.

Care for germinated tubers is reduced to regular watering with a small amount of water. Excessive moisture is not required, as it can lead to decay of the roots. Water as needed with Fitosporin solution.
