The bulbous plants owe their durability to the bulbs, in which they store organic substances, for them to regenerate again. These plants begin their vegetation very early and, under favorable conditions, they quickly grow above the surface of the formed beds. Some, like for example. narcyzy, squills and saffrons, they can stay in the same place for several years. Other, like tulips and hyacinths, need to be transferred to new positions every year. These plants come in bulbs of various shapes and sizes, some (e.g.. lily) they are characterized by a loose fit, scaly structure, other (e.g.. tulips) they are tightly compact. The use of bulb perennials is versatile – are suitable for planting on lawns, in perennial beds and cut flowers. Due to the very early beginning of vegetation, they require top dressing.It is recommended to use ammonium nitrate in the amount of 1 day after 1 m2. Besides, these plants require careful soil preparation, so that the onions can grow well.
Siberian onion (Scilla sibirica) it has spherical onions, diameter 2-3 cm, from which they grow 2-4 even leaves, length 10-15 cm, width 1 cm. It blooms in March – April, issuing a flower shoot in height 10-12 cm, on which there are blue flowers, collected after 2-3 in clusters. It grows best in slightly shaded places and in not too dry soil. Onions are propagated from incoming bulbs, which separates after digging in July, and from seeds. It often sows itself. The Alba variety deserves attention – about white flowers and Spring Beauty – with slightly darker flowers, azure-blue, double the size. The bulbs are planted in August – September, in depth 6-10 cm, depending on their size. Seeds are sown in the fall, in rows what 10 cm.
Eastern hyacinth (Hyacinthus orientalis) it grows up to the height 30 cm It has elongated leaves and a beautiful flower stalk, on which it is located to 30 bell-shaped flowers with an intense and very pleasant fragrance, in colors – from white to dark purple. Mainly used in greenhouse cultivation, sometimes it can be used to plant flower beds. Likes airy and well-drained soil, sufficiently moist. For field cultivation, the bulbs are planted from September to October – in sunny places. They require abundant fertilization, therefore, the soil should be fertilized in spring with manure or compost. The bulbs are planted at a depth of 12 do 20 cm – depending on soil firmness and onion size. The lighter the soil, the deeper the onion is planted.
Depends on the variety, hyacinths bloom from late March to late April. After flowering, cut the flower stalks, and at the end of June and the beginning of July, we dig up the onions, we dry and store until autumn in a ventilated and shaded place. Hyacinths can be propagated by separating adventitious bulbs, which form a small amount at the base of the onion. After separating them from the mother bulbs, dry them and plant them separately into well-prepared soil. We plant them quite densely and not too deep. These bulbs grow up and bloom after 3-4 years. The color scale of hyacinths is very large – from white through pink, blue to dark shades of purple.
Imperial crown (Fritillaria imperialis) has a large onion, the size of a fist, with a depression at the top, without covering scale, with the smell of garlic. Leaves slightly lanceolate, narrow, decomposing, of a length not exceeding 15 cm; quite large flowers, hung in a whorl after 6-10 pieces on high, sometimes up to one and a half meters, the stem, in red or yellow. The imperial crown is grown like other bulbs. It tolerates partial shade well, however, it is not suitable for driving. In winter, it requires covering. It is propagated by sowing or by separating the side bulbs. It blooms from late April to early May. Planting and transplanting along with separating dried bulbs should take place during the summer dormancy, no later than September. You shouldn't overdo it more often than what 5 years. The bulbs are planted quite deeply, depending on their size, greatest in depth 30 cm. The seeds are sown immediately after harvesting.
