Gladiolus and crocuses have a corm - bloated stem base. Some species of begonias have an underground stem shoot - a tuber. A modified root of a dahlia is called a root club. Many onions do not tolerate our colds and freeze, so their underground parts are excavated and stored at a positive temperature until the next landing.
Tulip, perhaps, the most famous bulbous plant. He is unpretentious, can tolerate long unfavorable conditions. Its abundant flowering depends on the correct choice of soil, timing of planting and timely feeding.
For 1.5 months, the bulbs are stored at a temperature of +25 to + 18 C. The temperature is then gradually lowered to + 10 ° C. In the cold (in the basement or in the refrigerator compartment for vegetables) bulbs are stored for 16 to 18 weeks. Then the bulbs, planted in a mixture of peat and sand, 3 weeks before the expected flowering are transferred to a heated bright room and watered.
Indoor bulbous plants - amaryllis, valotta, zefirantes, euharis do not require the same complex care. Enough after flowering to reduce watering, trim the leaves after wilting, put the pot with a bulb on a cool window sill and occasionally spray the surface of the earth.
Gladiolus , perhaps, is the most famous owner of corms. The peak of its flowering falls on autumn. In early October, after the flowering, corms are excavated. Carefully shake the ground and cut the stem at a distance of 12-15 cm from the base. The plant is examined: the branches are separated, the patients are removed, and if a slight damage is detected, the corms are cleared and the lesion is rubbed with green. Corms are put in boxes and dried for 5 weeks at a temperature of +25 ° C. Then it is transferred to canvas or gauze bags and stored in a ventilated room at a temperature of + 4-6 ° C. To store the gladiolus is better suited basement of the village house, but in the refrigerator corms can bend.
Corms of South African indoor plants Babian and Romulus require wintering for higher temperatures - around +20 ° C. They are stored in a mixture of peat with sand and during the wintering period they do not water.
Owners of tubers - this cyclamen, gloxinia and some begonias.
Tubers gloxinium and begonias fall after dying leaves are removed from the pot and placed in a mixture of peat and sand. Before laying for the winter from the tubers, the children are removed, and the place of their attachment is sprinkled with crushed charcoal, this procedure protects the tuber from the fungus. Until early February, the plants sleep soundly at a temperature of + 6 ° -10 ° C. Beginning from the middle of February, tubers periodically inspect: did sprouts appear? In the spring, the tubers are planted in a light nutritious land (leaf, peat, humus, sand 1: 1: 1: 0.5), put in a warm bright place and watered.
Cyclamen is a "plant on the contrary." When the brothers on the windowsill are in a state of deep peace, he pleases us with abundant flowering, and in the spring when everything awakens, this alpine violet falls into drowsiness. Therefore, the cyclamen tuber is also laid on the "wintering ground" in the spring - according to the same scheme.
Korneklubni garden dahlias dig in late autumn, when the stem and leaves turn black from the first frost. Approximately 30 minutes of dahlias arrange a "bath" from the solution of potassium permanganate. Large Korneklubni divided into several small, stacked in a canvas bag and placed in a cool basement with a humidity of at least 80%, otherwise they can dry out.
Remember that bulbs, tubers and corn-klubs in winter should be inspected at least once a month, in time to notice the damage and take action.
