What are Dahlia bulbs?

Dahlia bulbs are an underground root system that stores nutrient reservoirs, allowing the Dahlia plant to mature year after year without the benefits of seeds or spores. Dahlias does not have technically bulbs, the way it does tulips or hyacinth. Have non -polished or tender tubers; They do not survive winter frosts and must be protected from frost if they are to regenerate the following spring. However, their underground root system can be commonly referred to as a bulb composed of smaller tubers. After autumn, above -ground flowers and foliage shrink and die and leave the bulb to rest until spring, when it will grow and bloom again. Dahlia bulbs are not hard, as with Gladiolus. Real bulbs, as well as daffodils, have fleshy leaves underground that protect the central embryo. However, the tuber combines the stem and root, but it has swollen to suit more moisture and nutrients. Dahlia IS bulb composed of many different tubers, each of which is a separate lump. You want to hatch next season, each tuber must have one eye, whitish shotthat will grow vertically. Filming passes through the soil and turns into stems, leaves and flowers. The bulb can have a healthy eye -free tuber, healthy tubers with some eyes, unhealthy or shriveled tubers, and the "mother" of the tuber that produced this year Dahlia.

To get their own Dahlia bulbs, gardeners must dig tubers in the autumn, after the first light frost kills the leaves, but before the hard freezing and kills the bulb. They must maintain a part of the dried stem, but dead flowers and smaller roots can be cropped. After identifying various types of tubers, the gardener chooses a company, large, shiny eyes with eyes and the rest of the bulb. The tubers must be properly stored, far from sunlight, with dark the correct amount of moisture to remain viable. A cold temperature of 35-45 ° F (2-7 ° C) is recommended. They could be wrapped in sawdust, vermiculite or crushed paper to absorb further moisture without allowing them to completelyIf dry. For some climate, a garage or basement may be suitable; For others, the vegetable socket will be fine.

Dahlia bulbs can be planted in the ground, with eyes up, in May or June. Some varieties of Dahlia are hybridized as "forced" inside in winter. This means that they can be planted in vessels inside the dead winter and the temperature of the surrounding room is deceived into growth and flowering for Christmas or Valentine's Day.
