The bulbs are underground organs of some plants, which store stored nutrients during the cold seasons of the year, to be used in the sprouting of new stems during spring or summer.
Bulbs are usually underground, but they are not roots, they are stems that have evolved differently, but they retain all their parts. If we observe a bulb we can see the roots in the lower part, and its leaves with the shape of scale around.
Can bloom at different times of the year; those bulbs that bloom in the spring, such as the tulip, hyacinth or daffodils, should be planted in early fall. Bulbs that bloom in summer, such as gladiolus, begonia, lilies or dahlias, should be planted in early spring, when the cold winter temperatures rise.
Conformation of the bulbs
The bulbs are preserved by:
- Root: It is the part of the plant that grows in the reverse direction of the stem. It has fixing and nutritive functions.
- Stem: It is the organ of the plant that generally supports the branches, the leaves and the flowers. In general, it has functions of support and of conduction (For example: conduction of the sap).
- Buds: They are small ovoid bodies that develop.
Depending on the environment in which they develop, the stems can be: aerial, underground or aquatic.
Bulb planting
During bulb cultivation, the most important thing is to prepare the soil well where it is planted. The earth must be very spongy and well fertilized. To do this we will use Vegetable Substrate and as fertilizer we will use the Bio Fish Fertilizer which is especially suitable for all kinds of bulbs.
The bulbs can then be buried in their correct position: the area that ends up pointed upwards and the part where the roots exit to the ground. One trick to know the depth to be buried is to multiply the widest part of the bulb by two. The soil is pressed well over it and the plantation area is irrigated.
