Pisonia - home care, reproduction and transplantation
Kind pisonia is directly related to the nyctaginaceae family (Nyctaginaceae). In nature, they can be found in the subtropical and tropical zones of Australia, America, as well as on the islands of the South Pacific and Hawaii.
These numerous species have one distinguishing feature. And these are thin elongated fruits, on the surface of which there is a layer of a very sticky substance. Therefore, various insects and even birds of not very large size stick to these fruits. Due to this feature, this plant is popularly called "tree-breeders."
At home, only one species is cultivated - pisonia umbellata (Pisonia umbellifera). It is a low tree that branches quite strongly. In nature, its height can reach 5 meters. Oppositely located short-leaflets in length can reach 20 centimeters, and they have a smooth, shiny surface. Simple leaves have an oval-oblong shape, as well as slightly wavy edges. In nature, they are colored green, but at home, the most popular variegated varieties with large whitish or yellow spots.
Small whitish green flowers have a slightly sweet aroma. They are collected in fairly large loose apical inflorescences in the form of a ball or umbrella. At the end of flowering, pod-shaped fruits of an elongated shape appear.They are very similar to spread fingers, as they are located almost vertically, and their tips are directed upwards.
In an apartment, this plant can grow up to 1.5 meters, but at the same time it is slow-growing.
Home Care for Pisonia
For pisonia to grow and develop normally, one must know how to properly care for it.
Needs bright but diffused lighting. Shading from direct sunlight is required. The most suitable for placement is a window of eastern or western orientation.
Forms with variegated leaves especially need bright lighting, otherwise the picture may turn pale.
In the summer, does not tolerate heat. The optimal temperature for this plant in this period is 18–20 degrees. In winter, he has a period of rest, and the temperature in the room should be slightly reduced (16-17 degrees). It reacts negatively to drafts, in this regard, when ventilating the room, you must be very careful.
How to water
Watering should be regular and moderate. Watering is carried out after drying of the upper layer of the substrate. In no case should the soil be allowed to dry out. In winter, you can water a little less, but you must make sure that the foliage does not become sluggish.
For irrigation use exclusively standing water, which does not contain chlorine.
This plant does not require high humidity. It feels quite comfortable in rooms with fairly dry air.However, one should not forget to regularly remove accumulated dust from foliage. To do this, you can use a sponge moistened in clean water or a warm shower (make sure that water does not get into the pot).
Since this is a slow-growing plant, which itself is highly branched, it is not necessary to prune it. In very young plants, you can pinch the tips of the shoots for the density of the crown.
Suitable soil should be loose, saturated with nutrients, good permeation of water and air, slightly acidic or neutral. In a special store you can buy universal soil, but any baking powder, for example, vermiculite or perlite, will need to be poured into it. You can also make the earth mixture with your own hands. To do this, you need to combine sod, humus, leaf and peat soil, as well as coarse sand, taken in a ratio of 1: 1: 2: 1: 1. Do not forget about a good drainage layer, for the creation of which pebbles, expanded clay or shards of clay are suitable.
Fertilize should be in a period of intensive growth 2 times a month. To do this, use liquid complex fertilizer for indoor plants. Variegated forms need special fertilizers.
In winter, fertilizers can not be applied to the soil.
Young plantlets need an annual transplant, and you need to take a slightly larger pot than the previous one. Adult specimens are subjected to this procedure when necessary, for example, if the root system does not fit in the pot.It should be remembered that the roots of pisonia grow extremely fast and strongly.
This plant can be propagated by stem semi-lignified cuttings. This procedure is carried out in the summer. To do this, cut a stalk, on which 3 internodes must be present. They take root long and badly. To increase the chances, the stalk should be treated before planting in a preparation that stimulates root growth, and lower heating is also required.
Diseases and pests
Spider mites, mealybugs, scale insects or thrips can settle. At the first sign of damage, the plant should have a hot shower, but before doing so, pests such as worms and scale insects should be removed with a cotton pad dipped in a liquid containing alcohol. If it was not possible to get rid of the pests, then use special chemicals.
Pisonia can become infected with powdery mildew or gray rot. Powdery mildew must be controlled with a solution of foundationazole (or other similar means of action), and with gray rot - a fungicide.
