Calla Ethiopian family of Araceae shakes the huge size of the dense swept leaves and monumentality long flower stalk topped with yellow inflorescence-cob, funnel-shaped bracts Wrapped-veil - white, yellow or pink. As encrypted conspirator, calla (Calla) has a few more titles - and calla, and Richard (Richardia), and zantedeskhiya (Zantedeschia).
In the wild calla grows in swampy areas of South Africa. This is a perennial herb with fleshy tuberous rhizome height of about 80 cm; basal leaves on a high channeled petioles up to 40 cm in length and 25 cm in width. There are many varieties of calla lilies, which stems length ranges from 40 cm to 1.5 m - therefore distinguish high, medium and low forms of callas.
Calla different ruggedness and high ecological plasticity - Thrives significant variations of light, humidity and temperature. Location in the house for the callas selected from solar to semidarkness: better in partial shade in the summer and in the autumn - is closer to the window. In the summer Kallu can be taken in the garden, in a secure place. In late October - early November at first appear calla flower stalks and bloom until May, in June-July period of rest.
To simulate the natural growth conditions callas in nature, to reduce watering during dormancy - watered once every 10 days. At the end of the rest period is necessary to remove a lump of earth from the pot, clean Kallu from old leaves and soil, and to separate the offspring of dormant buds (0.5-1.5 cm in diameter Babe) for reproduction. Thereafter Kallu put in the same pot in fresh soil (a mixture of turf, leaf, humus, trofyanoy earth and sand in equal parts), having shallow rhizome.
When planting calla important that the ground was a false stem at the soil level. Separated from the mother plant and the offspring Babe planted in pots (Babe sprinkle 3-4 cm soil without orientation tops). After transplantation Kallu are slowly beginning to water and gradually increase watering for 2-3 weeks. During the growing season calla requires large amounts of moisture, so the pallet must always be water. Fertilizer watering (alternating mullein and fertilizers) conducted every two weeks, except for a period of rest.
Mineral fertilizers are applied as follows: in August-September Cullum requires a complete fertilizer; from October to mid-November calla fed nitrogen and potassium; then until mid-January - phosphorus and potassium, and then again resumed feeding complete mineral fertilizer. Recommended phosphorus fertilizer incorporated into the soil, and the rest to make fertilizer in liquid form. With a lack of nitrogen in the leaves of callas become dull and their ends are omitted; if the sharp ends of the dark green leaves are lifted - Kallam not enough potassium.
During the year, the monthly average from callas develops and dies on one sheet (spring and fall more rapidly), the dying leaves are removed. Summer leaves calla much smaller and denser winter. In warm, dry room leaves calla periodically sprayed, otherwise they can appear spider mites and aphids. For the normal development of leaves and inflorescences in autumn reduce the temperature of the contents of calla lilies to 14-16 degrees in the winter it is also required coolness.
