Dracaena yellow leaves

The dracena plant

The dracena is perfect to keep indoors both for its persistent foliage and because scientific studies have shown that it purifies the home air from numerous pollutants. For their anti-pollution action, the sanderiana, fragrans and marginata dracaena are particularly recommended. The former is commonly confused with bamboo cane. It can be kept directly in water, without the need to add soil to the container. However, it is necessary to change the water regularly, because the roots quickly consume the mineral salts. It also needs a lot of light. The dracena fragransit is the most common in apartments with its elongated leaves with a light and dark green color, which fall around the trunk. The dracena marginata, on the other hand, is distinguished by its narrow and long leaves, which end in a point. It is very popular because it is able to eliminate tobacco odors. In general, the dracena is a plant that grows well if exposed to a temperature between 18-20 degrees. In warm climate regions it can also be kept outdoors. During the cold months, however, it should be moved indoors or on the verandas.

The cultivation of the dracena

There are numerous varieties of dracena, different in size or in color and shape of the leaves, but require the same precautions. The dracena needs well-drained soil and exposure in a sunny area for the leaves to acquire a bright green color. Some species of dracaena never need to be decanted, others require ever larger pots in the growth phase. In this case, the decanting must be done in spring. The dracena does not need much care. In the warm months it should be watered in moderation, once a week, so that the earth is always slightly humid. An excess of water would, in fact, be fatal to the roots that could rot. In winter, before watering again, it is best to wait until the earth is dry. It is recommended to spray water on the leaves to eliminate dust and keep them shiny. Some species like warm, humid environments but, if the temperature is too high, we may easily notice it because the lower leaves will start to fall faster than usual.

Curiosities about the dracena

The dracaena belongs to the agavaceae family, which includes species typical of arid and semi-arid climatic zones such as the famous agave. 40 different species of dracena have been classified. Most of the varieties are native to the African continent and the equatorial belt of Asia. It seems that its name, which in Greek means dragon, is a tribute to Francis Drake, the first English navigator to circumnavigate the Earth in the 16th century. The dracaena, in addition to being a beautiful houseplant with a pleasantly exotic touch, proves to be of great use. It seems, in fact, that it has the ability to purify the air from pollutants and thus prove to be a precious ally for our health. The numerous products used in the home (such as perfumes, solvents, disinfectants etc. ) release harmful substances that over time accumulate in the air, making domestic environments unhealthy. The dracena is not only able to absorb these toxins like benzene, but it has the peculiarity of producing more oxygen than it consumes. Its presence in our homes is therefore an excellent aid to our health.

The dracena is a slow growing plant and has a long life span. The leaves of the dracena are, depending on the species, long or streaked. Some varieties have yellow-green streaks, which give a particular note to this evergreen plant and increase its beauty. We must not confuse the shades naturally present on the leaves with the lighter spots, which can appear and increase in size until they produce a total yellowing. The yellow leavesthey will fall off after changing color to brown. The appearance of yellow leaves is, in fact, a sign that the plant is in trouble. The formation of yellow leaves is caused by the increase in salinity in the potting soil due to the progressive watering. The water is, in fact, naturally rich in mineral salts. The best and quickest remedy is to transfer the dracena into a larger container and change the soil. A too dry environment can contribute to the appearance of yellow leaves. To grow well, the dracena needs humidity, which tends to decrease during the winter due to heating.
