How to grow up a beautiful dieffenbachia?
the Dieffenbachia (Dieffenbachia) - an ornamental evergreen plant of family of aroidny (Araceae) are from damp tropics of the Central and South America. The large leaves which are serially located on a stalk are floridly painted, with various options of drawing. Generally this combination of green color and color of an ivory in the form of specks, strips. In room culture this plant is parted for more than hundred years. There are types growing to 1,5 - 2 m of height.
Conditions of keeping. As well as all tropical plants, a dieffenbachia needs heat and high humidity of air all the year round. Prefers a bright diffused light, but well grows also in a penumbra in the depth of the room at additional artificial lighting. Influence of direct sunshine is inadmissible, on leaves burns develop. It is possible to hold in the open air in the summer. Air temperature within 18 - 24 °C is optimum, in the winter - it is not below 17 °C. In the summer the most admissible air temperature is 28 - 30 °C.
In the veseena - the summer period should be watered with plentifully warm, well settled water. In the winter watering moderate, water has to be warm. All the year round it is useful to spray a dieffenbachia soft warm water, to wipe leaves with damp fabric, sometimes to arrange a warm shower. As top dressing weak solution of mineral fertilizers is used: in the spring and in the summer - 1 time in 10 days, in the fall and in the winter - once a month. It is necessary to watch closely that the drainage opening always well passed water, if necessary to clean it.
The dieffenbachia belongs to plants which well grow on a hydroponics.
Change and reproduction . If necessary make change in mix from the sheet earth, humus, peat and sand (3:1:1:1) in a pot, a little bigger by the size, in the spring. At change is desirable to bury a stalk a little to stimulate growth of additional roots.
Make multiple copies a dieffenbachia top stem shanks which implant in water, in a sphagnum, sand or mix of sand and peat (1:1) at a temperature not lower than 21 - 24 degrees, having covered with a film. When rooting in water the shank is put in soil after growth of backs 2 - 3 cm long
Besides, it is possible to multiply a plant and stalk about 15 cm long pieces with 3 - 4 interstices. Having cut such shanks, cuts surely powder with charcoal and dry 1 - 2 day. After that shanks horizontally stack on slightly damp soil, having pressed them approximately half into a substratum. After growth of kidneys and emergence of leaves to the basis of escape pour the earth. As soon as saplings get stronger, replace them, without separating a piece of an old stalk - a shank, and having deepened it to the earth.
If after cutting of a dieffenbachia there was a naked stalk, then from knots new escapes appear over time. They can be used for reproduction again.
Old lower leaves at an adult dieffenbachia gradually fall down, baring a stalk. At full stripping it needs to be cut, soon it will acquire young shoots again.
At a scrap of the died leaves and other types of works it is necessary to be careful - juice at a dieffenbachia is poisonous.
of Edge of leaves become brown - from - for dryings of the soil or cold air.
The basis of a stalk is softened and turns pale - there was its rotting from - for remoistening of the soil at cold air temperature. This place can be cut out, powdered carefully with pounded coal and to replace a plant to the new soil. If rotting came far, then to implant a top, and to throw out the rest.
Turn yellow and leaves - from - for low the air temperature and draft are displaced; when rotting roots from excess watering; at very dry air; at defeat by wreckers.
Leaves turn pale and lose the coloring - too bright lighting or direct sunshine. It is necessary to rearrange a plant to more shady place.
Dying off of leaves - for old leaves it is normal, and young people can die off from - for cold weather, drafts and dry air.
On leaves there are black spots with a yellowish border - defeat by parasitic fungi, it is necessary to process the corresponding preparations.
From wreckers it is damaged by a shchitovka, a plant louse, a web kleshchik and tripsa.
