Garden tuberous begonias are thermophilic plants and cannot survive the winter outdoors. For the period of cold weather, the rhizomes are dug up and determined for storage. Begonia in the next season will again be covered with lush flowers with proper wintering.
The storage of tubular begonias both outdoors and indoors is different. We will consider how to save begonias for the winter in the article. You will learn about the features of winter care, whether it is necessary to dig up the plant and how to prepare it for the cold season. in addition, it tells what is the difference between wintering tubers at home and in the open field.
Features of winter care
In the first year, begonia tubers are small and weak. Therefore, they need special care. There is a risk of death of young rhizomes if left for storage with adult specimens.
- Young plants in the fall are removed from the beds and put together with a soil clod in boxes with a peat mixture. For first-year begonias, the state of rest is relative. In winter, their upper part remains green. The containers with flowers are placed in a bright and cold place. It is recommended to moisten the earth once every 2 months.
- In adult flowers, the lower part dies off by autumn. It is cut off, the roots are dug up, put into boxes with sawdust, peat or sand. Planting rhizomes are kept in a cool place until spring in the refrigerator or in the basement.
It is not recommended to store tubers in the cellar due to high humidity... This has a very negative effect on plants.
Rest period and awakening
Dormancy or wintering in tuberous begonias begins in November and lasts until early March. The flower grower must take care of the planting material: preserve it and prevent it from drying out. To do this, follow certain rules:
- You cannot send begonias to rest in early autumn. To prepare for wintering, they must gain enough nutrients.
- You need to dig up the tubers in late October - early November (before the onset of severe frosts).
In late March - early April buds sprout and begonia awakens. This is the right time for grafting and planting a plant:
- 2 months before planting, the tubers are removed from the container in which they hibernated and placed in a container for germination.
- The roots are planted upside down.
- Tubers are germinated in a room with a temperature regime of at least +18 degrees.
- Water it daily. The sprouts will appear within a few weeks.
- Separate the tubers before planting. Each half must have kidneys. Places of cuts are sprinkled with coal powder.
- Sprouted begonias are placed on the beds not earlier than the beginning of June. Choose a place that is well protected from direct sunlight and wind.
The difference between overwintering at home and outdoors
Caring for tubers of garden and home plants is different. To properly prepare them for wintering, take into account the characteristic features.
Rules for handling outdoor begonias:
- Flowers are removed from the garden with the arrival of the first hard frosts. There is no need to rush to dig out with light frosts - begonias tolerate a short-term drop in temperature.
- When the stems and leaves of the plant are dry, they are cut off.
- The tubers are removed from the ground, put in a box and put to dry.
- Containers with planting material are stored until spring.
They act differently with indoor begonias:
- Their tubers do not need to be dug out - the plants are in their pots.
- The stems are pruned as soon as they begin to wilt.
- Watering is reduced to a minimum.
- The flower is transferred to a cool place.
- So that the earth does not completely dry out, it is periodically moistened.
In the spring, the tubers are transplanted into a fresh substrate.... If there are many buds, they are divided into several fragments.
Sometimes indoor begonia stays green all winter. The flower is left in its place until spring, then transplanted.
Do you have to dig it up?
In order for the horticultural culture to survive the winter, the tubers are dug up only when severe frosts occur.
Autumn is an important stage in the life of a begonia.... During this period, she must stock up on nutrients, grow tubers, and form flowering buds.
Answering the question "should begonia be dug up for the winter", its condition and type are taken into account:
- Large street tubers are removed from the ground after wilting.
- Large roots of home culture are left in place for the winter.
- Flowers with small nodules and sprouted from seeds are dug up and placed in a cool, lighted place.
A flower grower should not rush to send outdoor plants for wintering at the first slight frost. But you can't drag it out either.
Preparing a tuberous plant for storage until spring
Begonias growing in the garden are dug up before the onset of severe frosts.... The foliage on them will finally fly around, and the stems will dry out.
Tubers are recommended to be removed from the ground with a pitchfork. They do not shake the earth from the roots.
Features of preparing plants for winter:
- Tubers are dried in a cool dry place.
- They are placed in a special container: in boxes or in paper bags.
Planting material is stored until spring at a temperature of + 7-9 degrees.
Features of wintering room begonia are different:
- She is prepared for rest in October.
- Reduce hydration and stop completely after a month.
- The top of the flower is cut off after wilting. If it does not dry out, leave it as it is.
Storage methods and conditions
There are three methods for preserving tuberous begonia: in the basement, in the apartment, in the refrigerator. The most popular way to winter tubers is in the basement:
- The dried planting material is placed in wooden boxes or boxes.
- Sprinkle with sawdust on top and send to rest.
- The roots are sorted out from time to time and the decayed parts are removed.
In an apartment, a place for tubers is set aside in the coldest room, for example, on the balcony or under the window.
There are 2 storage options:
- In pots... Flowers growing in indoor conditions are cut off and placed in a cold place.
- In the box... The tubers are placed in a container, sawdust or sand is poured on top.
The root system is examined once a month for signs of disease.... Can be lightly sprayed with a spray bottle.
In the refrigerator, tuberous material is stored when there is little of it:
- The roots are placed in a plastic bag with sawdust. There must be holes in the bag.
- Alternatively, wrap each tuber in a piece of paper and place it in the refrigerator in the fruit and vegetable compartment.
Wintering begonias will be correct if you adhere to the following rules:
- Do not plant the plant before the hibernation period is over. It lasts until the end of February.
- It is advisable to leave the planting rhizomes for storage in boxes with sand.
- Be sure to inspect the roots and turn them over. If there are rotten places, they are removed. Slices are sprinkled with wood ash.
Before planting, the tubers must be germinated.
Proper wintering guarantees the rapid development and vigorous flowering of indoor tuberous begonias for the next year. To preserve garden plants, they must be dug out so that they do not die. Tubers are removed from the ground carefully, avoiding damage.
