The name "calla" in the literature is often found in the description of the outside like members of the family Araceae - bilokrylnyka, aronnyka and zantedeskiyi but all these plants at home decided to grow only Zantedeskiyu (Zantedeschia) - exotic visitor from South Africa. Long time available to local growers was only Zantedeskiya Ethiopian (Zantedeschia aethiopica) - a large plant with heart-shaped, exquisitely curved leaves and tall (1.5 meters) stems that held thin yellow inflorescences wrapped in white blankets.
Humidity for "white" Calla (zantedeskiy) must be maintained within 70 - 80%, especially in high temperatures. For this pots with plants should be placed in the pan with a wet expanded clay, two times a day to spray the leaves or wipe them with a damp sponge. "Colored" Calle less demanding: they can be kept at a humidity of 50 - 60%, also set on trays of moist pebbles (moss, sphagnum) but spraying spend less and very carefully, or even replace just wiping the leaves to moisture dripping on shanks and caused rotting tubers.
By irrigation and soil moisture "white" Calla considered very demanding, as naturally they prefer to grow in marshy areas. During active growth mode of irrigation are recommended to maintain ample, but not to provoke stagnant water and rotting roots, it is desirable to carry out the procedure after drying top (not more than one centimeter) layer and drain excess water from the tray after 15 minutes. "Colored" Calle such abundant watering do not need the opposite - the stagnation of water in the soil can lead to the formation of mold on the tubers. These plants are watered with warm water is recommended, just on the edge of the pot and soil only after drying for 2 - 3 cm. After flowering for both Kalla reduce the frequency of watering, and "color" in 1 - 2 months completely stop. During this time, exhausted after flowering tuber moving nutrients from the ground part and it slowly dies. Sharply "enter" Kalla during rest, cutting off the leaves or limiting watering at other times, it is not recommended, otherwise the tubers are not fully ripe.
The temperature for Kalla to "white" and "colored" Kalla (zantedeskiy) has significant differences, although there are general rules, at elevated temperatures coupled with low humidity all Calla be impressed pests (aphids, spider mites, thrips) and fundamentally bloom with sharp drops it. Rhizomatous plant of the first growing season is recommended to be stored at 18 - 20 ° C, gradually reducing it after flowering to a temperature of 10 - 13 ° C, in which the "white" Calla must rest at least 1.5 - 2 months. "Colored" Calle develop better at 20 - 24 ° C and low fluctuation of day and night temperature has a positive effect on the correct formation cuttings their leaves, but for full ripening of tubers and laying flower buds, faded plants recommended moon contain no irrigation at 25 - 27 ° C. Hold bulb calla in such conditions can even dug condition, but leaves only, that within a month they handed nutrients in the tubers and after drying easily separated. Ripe tubers with leaves should be put on a dry winter in the fridge or cellar (t +3 - +5 ° C) for March - April. Successful storage is desirable to pour sawdust or placed in separate paper bags, putting growth point up and regularly monitoring their condition.
Transplanting, Planting Calla. After the rest period need all the home Calle landing (transfer) the new nutrient substrate. "White" Kalla (zantedeskiyam) the procedure is necessary to separate the child from mother plants sprouts, as they not only weaken the plant, but may be one reason for the lack of flowering. If done regularly pinched young side shoots regularly and carefully replace the top layer of soil in the pot, the rhizome Calla be left direct to 2 years. Pots for "white" Kalla should choose the size of the root system - wide (diameter of at least 15 - 20 cm), but not too deep. Drainage layer must be at least 5 centimeters, and augmentation of yield should be slightly acidic reaction. You can use the universal soil for Araceae and flowering houseplants or to cook a mixture of compost (humus) leaf and clean river sand, taken in equal parts and add them 1/4 of clay, two turf soil and superphosphate at the rate : tablespoon of fertilizer per 3 liters of the mixture.
