Caladium (painting on the leaves).
Caladium gets its name from the Malay word "heladi" ("a plant with edible roots"). Belongs to the family Araceae Caladium; genus includes 15 species of perennial herbaceous plants, common in South Africa. In nature, Caladium found in the forests, on the banks of rivers and reservoirs. By the end of the XVIII century, caladium is grown in culture.
Caladium (Caladium) - perennial, herbaceous, stemless plant with ornate spear or arrow-shaped leaves on a strong bare stalks. Rounded knobbly tuber Caladium Brown; kidney during germination pink.
There are numerous hybrids caladium, and each - a special form and pattern drawing sheet, its combination of colors in the pattern (white, yellow, green, pink, red, purple). For decorative beautifully colored leaf caladium can probably argue with Decorative leef begonias.
Caladium gained a reputation as a capricious houseplant - because, apparently, that is very difficult to conclude from its dormancy period. Maintenance requirements for different grades Caladium vary significantly. Caladium relatively shade-tolerant, but to maintain the bright color of leaves, they need to provide the intensity of scattered light. Most suitable for Caladium are north-east and north-west window.
Temperature during the growing season Caladium should not fall below 20-22 degrees. Since this plant has a pronounced period of rest (when caladium resets all the leaves), the fall and winter it tubers stored at a temperature of 16-18 degrees.
It would seem, tuberous plant should be afraid of moist soil, but as caladium naturally inhabit the river banks, the growing season, he is not afraid of excessive moisture. Summer caladium requires abundant watering and frequent spraying. For foliar spray Caladium better to use distilled water and use a spray that creates a fine spray ("artificial fog").
If caladium get large water droplets that long to dry, then from that formed on the leaves dark spots. Caladium dressing in the period of active growth is carried out every two to three weeks, using a complete fertilizer with equal amounts of nitrogen, phosphorus and potassium.
Since Caladium in the cold season have a rest period, but towards the end of summer and early autumn of their watering start to gradually reduce and then completely stopped. Caladium tubers in winter is stored in the same soil in the same pot in which the plant grew. In February or spring Caladium tubers are removed from the soil, cleaned of old roots and bases of leaves, planted in fresh substrate.
Land mixture Caladium should be fertile enough acidic and contain the following components: polupereprevshy sheet substrate, humus soil, peat and coarse sand in equal parts (instead of peat can be used softwood land). A bucket of this mixture was added a glass of dry mullein.
When selecting a container for planting caladium tuber should be noted that the diameter of the pot should be twice the diameter of the tuber. At the bottom of the pot is placed drainage layer, and then - a layer of coarse sand and half cooked, well moistened substrate, which is placed a slide. In the hill make a groove that is filled with sand and planted it caladium tuber so that about a third of the tuber was submerged in the sand. Then, in the pot add the remaining earth mixture.
If planted caladium tubers shallow, it generates a lot of children, but at the expense of size and decorative leaves. This feature can be used if you want to get as many caladium tubers for propagation.
If nodules Caladium young, the pot 10 cm in diameter are planted 2-3 pieces, and in the pot with a diameter of 15 cm -3-5 pieces. The most beautiful plants develop from adult caladium tubers second year. Some amateur growers to produce compact shrub with large numbers of caladium leaves recommend to plant tuber crown down.
Before the advent of germs caladium watered very carefully, otherwise the tuber rot; during this period of tuber plants can quickly abyss from excessive moisture. After the appearance of the first leaf caladium rolled over into a larger container. Substrate moss top cover which prevents excessive moisture evaporation.
Vegetatively propagated caladium bulbs small child or dividing large parent bulbs (on delÑ‘nkah necessarily be one kidney). All slices sprinkled powdered charcoal or treated with a weak solution of fungicides (fundazol, benlat, bayleton).
Caladium and propagated by seeds. In this type of reproduction is cleaved variety of features and the result may appear plants, leaf color which is different from the original forms. You can purchase seeds Caladium in the store, but you can try to artificially pollinate your plant (Caladium quickly produces a flower arrow).
If successful, the artificial pollination seeds Caladium mature in two months. They were seeded immediately after harvest in the mixture of leaf and sand in the ratio (4: 1) to a depth equal to the diameter of the seed. Good drainage in the pot will ensure successful germination Caladium and favorable development of seedlings.
For seed germination caladium requires a very high temperature. Top container with cover crops and the temperature of the glass substrate is not below 25 degrees (preferably 30 degrees). Shoots CALADIUM appear after 2-3 weeks (depending on the temperature of the contents) after sowing. Watering the soil to dry out and emerged seedlings need an atomizer. The first time is better to spray crops with a solution fundazol. Occasionally lift the glass to air.
Caladium seedlings dive twice, and by the fall they will form small nodules. Caladium affected aphids, mealybugs, spider mites. If you notice any of these pests, the treated plants pyrethroid insecticides.
