Some of them, such as daffodils, snowflakes, some tulips and sapphires, are found wild in the Mediterranean. Both these regions determine the period of summer dormancy for plants, in which drought is the main factor forcing it. It is worth knowing this fact, because ensuring the bulbs are dry in the summer is an important rule in their care. That is why the bulbs of some species of spring flowering bulbs should be dug up before summer, ie in late June and early July. This applies primarily to tulips and hyacinths. The temperate climate species, e.g.our native snowdrops, snowstorms, dice checkerboard, but also Spanish hyacinth, snowball and some sapphires. The signal to dig out is yellowing and drying of the leaves. You should not dig out the bulbs with the leaves still green, which are still assimilating, as it weakens the bulbs. Digging out the bulbs also prevents their excessive thickening and fineness. After the bulbs have been dug up, they are dried, sorted and stored in dry rooms at room temperature. For re-planting in flowerbeds, the largest bulbs are allocated, since only such bulbs will bloom. For example, the bulbs of most cultivated varieties of tulips and narcissus should be at least 12 cm in circumference. They are planted again in late September or October.
