Pelargonium Graveolens

Generalities pelargonium graveolens

Pelargonium graveolens is a branched, slightly hanging, branched plant. It has palmate leaves, lobed toothed, rough on the upper part of light green color, which give off a characteristic odor, if rubbed. By stroking the leaves between the hands and passing them over the skin, a repellent effect is obtained against insects, especially mosquitoes. As for the flowers, these appear small, not particularly decorative, of pink color with a purple spot on the two upper petals united in umbel. The geranium flowering occurs in the spring season, from June to October. One of the characteristics that distinguishes this species from the others is its particular scent of roses that give off its flowers in the flowering season.


This plant grows on acid soil without limestone, commonly used forest soil mixed with sand and clay. The fertilizations take place using liquid fertilizer to be administered from April to September every two weeks. If we wish to cultivate this species, we will have to choose a luminous place and where the rays of the rays arrive for most of the day, directed towards the plant. In fact, it loves sunny positions and mild temperatures. Moving on to the topic of watering, the Pelargonium graveolens needs abundant irrigation in the summer, especially on plants exposed to the sun. During the colder season, instead, it is good to reduce watering because the plant must not have too moist soil to avoid problems such as rot and consequent death of the same.
Pelargonium grows well on the terrace at room temperature from April to October. During the winter the vase must be collected in a protected environment, not very heated. If it is watered and kept in a bright environment it can become a houseplant.


The multiplication of the pelargonium graveolens happens by cutting.
In summer by apical cuttings of cm. 8-10 cm., Taken from the stems, after treatment with rooting hormone, all this on a mixture of peat and coarse sand. The compote must be moist, placed in light shade at 16-18 ° C. After a month and a half, when rooting has taken place, they settle in pots filled with above-ground soil. It is possible to grow geranium in the garden or on the terrace of the house. It is essential to place the plant in a sunny and full of light area.

Pelargonium Graveolens: Pests and diseases

As for pests and diseases that can attack the plant, it fears the attack of white aphids and scale insects. Besides these two problems to which the plant is often subject, there are other adversities that can cause the weakening and slowing down of plant growth. Among the most common we recall the attack of mites, nematodes, molluscs in the genera Helix and Limax, the development of gray mold often caused by Botrytis cinerea, the attack of the larvae of Melolontha melolontha and Agriotes lineatus and of the caterpillars of Cacyreus marshalli . Another danger for the plant is constituted by the blackening of the stem due to the development of bacteria. If one of these problems is to be faced, in the best garden centers it is possible to find specific pesticide products for this species.
