Green balcony plants
These plants are very ornamental and develop colorful flowers that give liveliness and harmony to an environment. Our choice falls on two green plants much appreciated by florists. We therefore deal with the description of coleus and caladium. The coleus is a plant appreciated for the beautiful shaded colors of the leaves and is particularly suitable for growing in pots and boxes. The coleus is of herbaceous type with leaves of different sizes, rather soft, oval and elongated with variously serrated margins. It is widespread in numerous varieties with a very wide range of colors and is also appreciated as a houseplant or for creating borders in gardens. It belongs to the Labiatae family and is native to the tropical islands of the Pacific. As far as caladium is concerned, it belongs to the Araceae family which includes many species with curious and beautiful forms. Caladium can easily be defined as the most prestigious plant of the whole family as it is very appreciated for the splendid colors of the leaves ranging from ivory to green, from pink to brown, with all the intermediate shades. It is a tuberous plant, but it is difficult to find the tubers on the market, so you can buy the plants ready, vegetated, very suitable for decorating balconies and apartments. Caladium is to be considered primarily a balcony plant; its duration is limited to three or four months and after this period, the leaves begin to turn yellow and collapse.
Green terrace plants: coleus cultivation
The coleus are cultivated as annual species, by sowing under glass in February. The very fine seeds must be scattered on the fine and sandy soil without being buried. Once the plants have appeared, they can be transplanted in pots, taking care to repair them until spring. Then they transfer with a second transplant into the vases or boxes of the balconies. Their ideal environment requires a very fertile soil mixed with sand; However, it is preferable to avoid exposing the plants to full sun as only light is needed for development; direct exposure to the sun's rays can cause the leaves to bend which partly lose their bright colors. Like all flowering species, also coleus needs weeding of the soil especially in the summer period with a frequency of one every fifteen days. The waterings must be abundant and administered with not excessively cold water but possibly rested, so that the heavy metals present in it are deposited on the bottom. Another advice is to use distilled water as it is completely free of limestone.
Green balcony plants: coleus fertilizer
In addition to the topping that is carried out after each transplant, other maintenance interventions are recommended: in fact, if the coleus will be trimmed more than two or three times during the summer, they will branch even more and consequently the foliage will become much thicker. The soil must be constantly kept light and porous, therefore it is advisable to carry out weeding before using soluble fertilizers based on green leaves. The operations to multiply this plant are very easy indeed, in autumn it is enough to cut a sprig with at least four or five buds and insert it in a vase. You will immediately notice how easily and quickly the roots will develop. The vase with this young cutting must however be preserved until it becomes an adult at a constant temperature of about twenty degrees in a shaded area.
Cultivation caladium balcony
For the cultivation of caladium on a terrace it is necessary to procure vases with a diameter of around twenty centimeters and inside fill it with soil mixed with peat to obtain good drainage. At this point the pots can be exposed on the balcony, but keeping them away from drafts while in summer the high temperature does not create problems. When the vegetation of the plant becomes six or seven centimeters high, make sure that the sun exposure is satisfactory. At this point you can proceed with periodic watering never to be carried out in the hottest hours of the day because you run the risk of burning the leaves. The best fertilizers for caladium fertilization are those that are liquid and low in nitrogen. To obtain a caladium plant that is always rich in leaves, it is necessary to continually carry out topping operations (using normal scissors) to prevent it from ever exceeding the height of twenty centimeters, otherwise the stems may tilt and the buds may no longer be productive. Another advice is to cultivate them from the beginning in large pots because the root development is quite wide, and the roots being a plant derived from a tuber, they tend to escape from the soil. To avoid this inconvenience, it is advisable from time to time to add some soil to cover any spilled roots. If all these precautions are followed, the plant can live for three or four years and periodic maintenance can also improve the quality of the leaves by avoiding or delaying yellowing.
