How to store dahlia root tubers

Harvesting dahlia roots

After frost, the plants and leaves wither and die. At this time, you should immediately cut off the above-ground stems and leaves and dig out the tubers. If it is too troublesome, you can put the pot together with the pot into the greenhouse. Before harvesting, pay attention to screening the varieties and selecting the best ones to ensure the purity of the varieties.

Before storage, it is essential to trim the withered stems and leaves, and cut off all the dead leaves within 15 cm of the rhizome. To prevent damage to the roots, dig out the entire mound as much as possible. After digging them out, dry them in the sun for a few days. After the soil on the tubers is dry, shake off the dirt and place them in a greenhouse where the temperature does not exceed 5 ℃, and keep the temperature as constant as possible.

Storage of Dahlia Root Tubers

The storage place must be sterilized and disinfected. When placing them, place them on the ground in the greenhouse with the root neck facing upwards. To prevent premature germination and root rot due to heat, it is usually better to stack them in 3 to 5 layers and bury them with slightly moist sandy soil.

During storage, check frequently and cut off useless rhizomes in time. If you find that the surrounding sand is too dry, do not water directly. You can take out the tubers, spray the sand until it is moist, and then bury the tubers.

Another storage method is to divide the dried tubers together with the adventitious buds growing on the root neck. After splitting, apply wood ash on the cut, put it in a wooden trough or wooden box, and fill the gap with sawdust or dry sand. Then store the wooden trough or wooden box at 3~5 ℃. Do not move it casually during storage. This method is easy to keep and use, and can also save storage space.

Dahlia storage precautions

The tubers of some varieties of dahlia are difficult to store, such as dahlia, dahlia odora, etc. When storing the tubers of these varieties, do not mix them with other varieties. You can dry them at high temperatures and place them in wooden boxes or flower pots. Cover the tubers with a small amount of dry sand and store them at 3 to 5 degrees Celsius. Alternatively, a few days before the frost season, move it into a greenhouse at 5 to 10 degrees Celsius, remove the flowers and buds, and cultivate it for about 15 to 20 days to allow the nutrients to be fully concentrated in the tubers. Then remove the stems and leaves from the plant and store it in the original pot.
