HOW TO GROW AND CARE FOR OUR PLANTS
There Murraya it is a delightful border plant but also an easy to grow pot plant and particularly appreciated for its leaves and aromatic flowers.
Clado: Euroside II
The genre Murrayaof the large family of Rutaceae, it includes plants native to the areas of the South Pacific.
These are evergreen perennials mostly shrubs or small saplings, similar to citrus plants, of which there are numerous species but the only one used for ornamental purposes is the Murraya paniculata, characterized by a light-colored wood similar to boxwood with which it is often confused and small leaves of a beautiful shiny bright green color, pinnate, up to 5 cm long and about 3 cm wide.
The flowers gathered in corymb inflorescences appear for most of the year. They are bell-shaped with white and very fragrant petals, like the leaves while the fruits are red. Berries are highly sought after by birds and flowers by bees.
The ideal growing environment for Murraya it is a hot and very humid place. It requires excellent lighting, even direct sunlight as long as it is not during the hottest hours of summer days.
In order to flower, it requires winter temperatures not below 18 ° C.
There Murraya in temperate climate zones it can be grown outdoors because it is excellent for making borders and hedges. If grown in pots, in summer it is advisable to take it outdoors, in a position sheltered from excessive sunlight.
During the whole spring-summer period, water abundantly avoiding water stagnations which are not tolerated in any way and wait for the soil to dry on the surface before proceeding with the subsequent wetting. During the autumn-winter period it must be wet with much more moderation: the lower the temperature, the more moderate the watering must be.
The humidity of the air is essential therefore spray the leaves daily with warm water and place the pot on expanded clay or gravel where a trickle of water will be constantly present (which will never be in contact with the roots) which, evaporating, will create a humid environment around the plant.
TYPE OF SOIL - REPOT
It is repotted every year in spring using a fertile soil mixed with peat and coarse sand to favor the drainage of the watering water, in equal parts.
Starting in spring and throughout the summer, administer a good liquid fertilizer in half doses every two weeks with the watering water.
It is advisable to use a fertilizer that in addition to having the macroelements such as nitrogen (N), phosphorus (P) and potassium (K) also has microelements, that is to say those compounds that the plant needs in minimal quantities (but still needs them) such as magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo), all important for plant growth.
The Murraya if they start to have a too bursting posture, they can be vigorously pruned at the end of winter up to 20 cm from the base.
The multiplication of the Murraya it can take place by cutting or by seed.
MULTIPLICATION FOR TALEA
At the beginning of spring, apical cuttings 10-15 cm long are taken, cut with an oblique cut immediately under a node.This type of cut is recommended as it allows to have a greater surface for rooting and avoids the accumulation of water on that It is important to use a well sharpened blade to avoid fraying the tissues while taking care that it is well cleaned and disinfected, preferably over a flame, to avoid infecting the tissues.
After having recovered the cuttings, it is important to wait about 7 days to heal the cut wound, before proceeding with the transplant, then settle in a compote formed by peat and coarse sand in equal parts by making holes with a pencil, as many as there are cuttings The pot is covered with a plastic bag put on a cap after placing sticks in the ground to keep the plastic away from the cuttings and having tightened the bag with an elastic band to the pot, to prevent moisture loss. in an environment at about 30 ° C and every day the plastic is removed to control the humidity of the soil and eliminate condensation from the plastic that will surely have formed.
Once the first shoots start to appear, it means that the cuttings have rooted. At that point the plastic is removed definitively and the pot is placed in a brighter area, at the same temperature and expects the cuttings to become stronger.When they are large enough, they will be transplanted into the final pot and treated like adult plants.
PARASITES AND DISEASES
The plant loses its leaves
If the plant loses its leaves for no apparent reason, it means that the ambient humidity is too low.
Remedies: increase the sprays to the canopy and arrange the pot as indicated in the "Watering" paragraph if this has not yet been done.
Presence of insects similar to small white butterflies
Little white bugs definitely are Aleirodidi, commonly known as white flies. To understand if it is about them just shake the plant: it will rise like a white cloud. They are found mainly concentrated on the lower page of the leaves. The damages are caused by the subtraction of the lymph, having a stinging-sucking mouth apparatus and by the punctures they make in the tissues for the deposition of the eggs. They also produce honeydew (their sugary and sticky droppings) which can cause smoke and can transmit virosis.
Remedies: treat with specific pesticides.
Presence of small whitish animals on the plant
If you notice small white-yellowish-greenish mobile insects you are almost certainly in the presence of aphids or as they are commonly called lice.Observe them with a magnifying glass and compare them with the photo on the side, they are unmistakable, you can't go wrong.
Remedies: treat the plant with specific pesticides readily available from a good nurseryman. These are generally systemic products, that is, they enter the plant's lymphatic circulation and are therefore absorbed by insects during feeding.
The genus was honored to J. A. Murray (1740-1791) professor of botany in Göttingen, a city in Lower Saxony, Germany.
The species Murraya koenigii is also known as thecurry tree as its leaves are widely used in Indian and Sri Lankan cuisine. It does not enter the composition of the spice called curry, a yellow-mustard powder widely used in all Asian countries, formed mainly from (the spices may vary depending on the country): black pepper, cumin, cinnamon, turmeric, coriander but also cloves, ginger, nutmeg, chili pepper.
It is a very used plant for the realization of bonsai.
