Yucca, the leaves turn yellow: "who is to blame" and what to do?

Yucca is a decorative evergreen tree plant of the Agavov family. The genus Jukka has 40 species, many of which on the Black Sea coast (in the Caucasus, in Sochi, in the Crimea and in the south of Ukraine) grow under the open sky. In room floriculture is usually used yucca aloe-leafy, resembling a palm tree. This tree grows to a height of 4 meters, so it takes a lot of space.

But the microclimate of our apartments and offices does not always suit her, often the plant begins to ache and turn yellow. Let's try to find the reasons for this and eliminate them so that your house is again decorated with a green and healthy yucca. The leaves of yucca turn yellow, most likely because of overmoistening. It is urgent to take action. For this, the plant is taken out of the pot and carefully inspects the roots. Cut all rotten, to a healthy place and cut sections with some fungicide or pink (but quite bright) solution of potassium permanganate, sprinkle with wood ash. Transplant the plant in a new soil (suitable mixture for palm trees) with good drainage, it is desirable to add to the ground coarse sand. You can immediately water the plant with a rootstock, and then water them 3-4 times more.

In the case where the roots are already rotten, it remains only to try to use the top of the plant as a cut (also treated with corn root). If the plant is flooded, but quickly noticed, it does not necessarily have to be transplanted immediately. You need a thin, sharp stick (or spoke) to pierce the soil to the bottom in several places.

Due to overmoistening and stagnation of air, yucca can be affected by a dangerous fungal disease - stem rot. As a result, a part of the crown or stalk (or one of several stems) rot. You can identify the sick parts of the plant by touch, they become soft (if the stalk is probed by air, but as a whole it is solid, then the plant does not get sick). If you do not immediately remove the damaged parts (to a healthy place, with a fungicide treatment), then all yucca will die. Pruning this, unfortunately, helps only if the whole plant is not affected yet.

For the same reason (waterlogging), yucca can become spotty with leaves. This disease of fungal or bacterial origin, it is expressed in the appearance on the leaves of grayish-brown spots ("mosaic" yucca). Care for a sick specimen is to remove spotted leaves, treat the fungicide and reduce watering. Note, yucca is not advisable to spray to avoid diseases.

There is another reason that the yucca can hurt. The leaves turn yellow, possibly due to too high a temperature in the winter. The temperature for the yucca wintering should be about +8 ... + 10 degrees. If the yucca is in a winter in a too warm room, then begins to discard the leaves. In this case, only the transfer of the plant to a place with a suitable temperature will help.

If the foxes of the yucca are twisted and soft, brown at the edges, then the temperature in the room is too low or the plant froze at the cold window. The dried brown ends of leaves or drying of their edges is caused, as a rule, by excessive dryness of air. By the way, if you have an aquarium, then the yucca around him will feel great.

Lack of light can also affect the plant negatively. Because of this, often yucca is ill, leaves turn yellow. This problem can be solved by arranging the plant additional doroughing (preferably a special lamp for plants) or by moving it to a lighter place, for example, to the south or east window.

But if the leaves formed dry, pale spots, then it happens, on the contrary, from the excess of the sun. To direct sunlight, yucca is also sensitive. Leaves turn yellow and just from old age, after all, in nature they gradually die off, exposing the trunk. After transplanting or changing places and conditions, yucca can also lose leaves. Often this happens after the purchase of the plant, because "moving" for it - a strong stress.
