A shrub with a delicate and pleasant appearance, the foliage and flowers are very aromatic, reminiscent of the scent of orange and lemon. In regions with mild winters, they can also be grown in the garden, in a place sheltered from frost and winter wind.
For plants to grow at their best, they need specific climatic conditions and adequate exposure. The Murraya auriculata prefers very bright locations, and can be grown in a place exposed to direct sunlight, during the summer season, from April to September, can be grown outdoors, in sunny or semi-shady. Let’s now see what the needs of the plant in terms of irrigation are.

Soil and multiplication
When you want to grow a plant species in the best possible way, it is important to choose the most suitable soil. Not all plants need the same type of soil. Depending on the characteristics of the plant, you should select the type of soil best suited to the growth of the plant, in this case the Murraya auriculata. Rutaceae love soft and very well drained soils; it is advisable to use a compound consisting of two parts of peat, one part of sand and half part of pumice stone.
On the market, it is easy to find a compound ready for citrus fruits, ideal also for the murraya. For a balanced development of the root system, repot the murraye every 2-3 years, in spring.
The multiplication takes place by seed, in spring, or by semi-woody cutting, at the beginning of the summer.
