When and how to dig dahlias in autumn

Timing of harvesting

When determining the optimal timing, take into account, first of all, regional features.

  • Early harvesting of bulbs affects their safety in the winter, because they manage to gain the necessary amount of nutrients.
  • If you move the bookmarking dates, the risk of freezing the root tub increases due to the onset of autumn frosts.

Central lane and Moscow region

In heat x climatic regions, flowering ends by mid-autumn, around October.

This is a suitable period to dig a bulb already ripened for wintering, filled with nutrients.

The term is shifted to the beginning of the winter season, when short-term frosts are observed, but severe frosts are not expected.

The dried and withered stems and foliage will tell you about the readiness of the tubers.

North

In the northern areas, including in the Urals, Siberia, the Leningrad Region, the risk of sudden autumn frosts is increased, so they have been trying to dig dahlias from the end of September.

In case of an unexpected strong drop in temperature, it is recommended to get tubers from the soil in 3 days.

Dahlia varieties with a dark bud color are characterized by reduced frost resistance. They are sent to be stored earlier than others.

South

Floriculturists in the southern climatic zones can postpone bulb digging for 1-2 weeks longer in comparison with the central strip, around the end of October – the first days of November, provided that the weather is warm.

Bookmarking rules for the winter

Before you dig up dahlias in autumn, you need to remove the aerial part, leaving stems up to 0.2 m long.

Weakened and diseased plants do not preserve – they are burned to prevent the spread of infectious diseases and preservation of pest larvae in the ground.

Digging to the roots, retreat a sufficient distance so as not to damage the corms.

The dug flower must be dried

Instructions:

  • Initially, the bush is dug around the perimeter and when help the shovels are removed along with the roots and the ground.
  • The earth is shaken off, the flower is left to dry under natural conditions.
  • The stems are cut to 7-10 cm.
  • Under the base remove thin roots.
  • I have Fresh green shoots located in the root tubers are broken down at an angle so that in winter they do not grow early.

When removing plants from the ground, they do not pull on the stem, because this will violate the integrity of the roots and adversely affect the preservation.

Flower bulbs are washed under running water from soil residues and soaked in a disinfectant solution designed to increase the shelf life of planting material.

For disinfection, ordinary potassium permanganate, diluted to light pink, is suitable. After processing, the tubers are laid out for drying under natural conditions.

Storage melting

Preparation

Many flower growers are ready to set for home storage divide the bulbous nest into parts, leaving it along the neck with buds and cutting off all remaining roots and shortening the stems to the maximum possible length.

Separation allows you to store planting material without the appearance and spread of rot.

In the process, the tubers are inspected and sorted, cutting rotten fragments to a healthy layer, brabatyvaya them after cutting green paint. Only those that, as a result of the sanitary procedure, retained at least 1/3 of the kidneys are left. Smaller fragments are thrown out.

The presence of holes indicates pest damage, but is not an obstacle to storage.

Fully bleached necks that began to deteriorate cannot be laid.

The onion dividers are washed with water, the sections are treated with fungicide and left for 6-10 days to heal the wounds on the roots and form a thin crust on the surface, preventing from excessive evaporation of moisture.

Do not save the uterine root of the plant, because he will give only weak shoots next season.

Prerequisites

Before sending the root tubs for wintering, you should mark them so as not to confuse the varieties. This will make it easier to plant flowers for next season.

Correct microclimate:

  • temperature within 3-7 ° C;
  • humidity from 80% and higher;
  • well-organized ventilation;
  • isolating the root tubers from each other, preventing contact;
  • laying the root neck downward.

A small amount of planting material is stored in a refrigerator, avoiding the proximity to vegetables, because increased humidity causes fungal diseases.

Tubers can be stored in the refrigerator

A large volume is placed in separate containers – buckets and plastic or wooden boxes, cardboard boxes and placed in the basement, on the balcony or in the cellar.

In any method, the bookmarks are placed on the tubers with an auxiliary substrate or suitable material.

  • Sawdust. A simple and affordable method to save planting material. A large fraction or shavings are suitable, because small sawdust will dry the bulbs, drawing out all the moisture. It is possible to lay out in 2 rows with a layer of sawdust sprinkling.
  • Peat. Suitable horse, which fall asleep laid out on wooden boxes delenki, leaving the neck half open. In winter, the peat layer is moistened to prevent dahlias from drying out. Peat can be mixed with garden soil in a ratio of 3: 1.
  • Land. Bulbous dividers are laid out in boxes covered with newspaper or paper and sprinkled with earth.
  • Sand. River sand for filling planting material in the storage tank must be dry. The roots are immersed in 1-2 layers and covered with burlap on top. In winter, the sand does not moisturize.
  • Packages. Tubers are stored in polyethylene along with sawdust that absorbs moisture, otherwise the root tub rotting process will begin from the formation of condensate. The package is tied, but openings are made over the entire surface for air access. Once every 2 weeks, the material is inspected for mold and rot. Damaged items are thrown away.
  • Film. Each dividend before laying is treated with a fungicide preparation or sulfur powder, wrapped in a film, put in a cardboard box.
  • Bags.Canvas bags store dahlias in dry form, without filler, hanging them to a height in the basement, apartment, cellar, avoiding contact with the floor, away from damp places.
  • Paraffin. The most effective method, providing the highest percentage of safety. Only suitable for early varieties of dahlias, as after waxing the bulbs, it is possible to wake up much later. Recommended for storage of rare varieties. Paraffin is heated to a liquid state in a steam bath, allowed to cool to an acceptable temperature. Each bulbous delenka is lowered and held until a wax crust forms. After processing, the root tubers are put in a bag with sawdust and stored in a cool place.
  • Clay. Like paraffin, it covers the root tub with a protective layer and increases the shelf life. The clay is bred to a thick state and the roots are lowered into it, allowed to dry and sent to a suitable container.
  • Vermiculite. The granular material is suitable for pouring dahlias when stored in boxes or plastic bags. It is not used in rooms with low humidity, as it absorbs a significant amount of moisture from the surrounding air. When laying in boxes, the layers of vermiculite substrate and root tubers alternate.

Care rules

Planting stock laid for the winter should be regularly inspected, timely removing rotten and moldy instances. When the filler dries, the bookmarks are moistened.

It will not be superfluous to protect planting material from the attack of pests. For treatments of storage containers and root tubers, insecticidal agents of a systemic spectrum of action are suitable. The container is sprayed, and the onion dividers are immersed in an aqueous solution for 15 minutes.

To summarize

You can save dahlia tubers dug in the fall in different ways in the apartment, basement, cellar and on the balcony. The main condition is to pre-prepare them and maintain the correct temperature and humidity.
