Planting and introduction of [incense leaf geranium]

Fragrant leaf geranium is one of the varieties of geranium. Many people like potted plants to decorate their homes. Next, let's take a look at the planting and introduction of fragrant leaf geranium.

The geranium is a kind of geranium native to southern Africa, especially South Africa. They are sometimes called geranium and mosquito repellent because they belong to the same family, but actually belong to the genus Pelargonium. Pelargonium fragrans has a very important position in the perfume industry. They are cultivated in large numbers to distill the aromatherapy of leaves.

Pelargonium geranium is very popular because of its volatile aroma. Can be used to make essential oil, its main ingredients are geraniol, citronellol, linalool and so on. Fragrant leaf geraniums have a variety of flavors, including rose, citrus, mint, coconut and bean curd, and a variety of fruit flavors. Because of easy cultivation and management and high yield of essential oil, it can be used as a substitute for low yield of other essential oils, such as rose essential oil or orange blossom essential oil.

The common name of the geranium is the rose geranium. In addition, the leaves of geraniums are not "incense leaves" in cooking spices. Incense leaves are the leaves of laurel.

The geranium prefers a warm, moist and sunny environment. Poor cold resistance, afraid of dampness and high temperature. The suitable temperature for growth is 13-19 ℃ from March to September and 10-12 ℃ in winter. It is semi-dormant from June to July, so watering should be strictly controlled.

Suitable for fertile, loose and well-drained sandy loam. The winter temperature is not lower than 10 ℃ and can withstand 5 ℃ low temperature in a short time. Single petal varieties need artificial pollination in order to improve the seed setting rate. The seeds mature about 40-50 days after anthesis.

When cultivated as an annual crop, seedlings are generally raised in a greenhouse or hotbed in the winter of the previous year, with mature shoots about 15 meters long and 1-2 top leaves. The temperature of 8-10 ℃ should be maintained after rooting. After the frost of the following year, the plant was planted with a row spacing of 50-60 cm. It can be harvested once each year from June to July and in the middle of October, and 3-4 times at most. The oil yield is about 0.1-0.2%.

Planting skills of fragrant leaf geranium

1. Hustle and bustle

Geranium requires fertile soil with good drainage. Pot soil can be mixed with rotten soil, rice chaff ash and garden soil, and then mixed with a small amount of superphosphate.

2. Watering

Geraniums are resistant to drought and afraid of stagnant water. Therefore, in the process of growth, water should be properly controlled. Too much watering, basin soil water content is too large, will cause overgrowth or rotten roots. When the spring and autumn growth and flowering is exuberant, it can be watered more appropriately, but it should also be appropriate to keep the basin soil moist. If the temperature is low in winter and the plant grows slowly, it should be watered as little as possible.

3. Fertilization

In cultivation, in addition to applying sufficient basal fertilizer, thin liquid fertilizer can be applied every 7-10 days in the growing season, especially in the peak flowering period. It is better to dilute with rotten livestock and poultry manure with water, and it can also be poured with rotten cake fertilizer. 3-5 days before fertilization, little or no watering, watering when the basin soil is dry, is more beneficial to root absorption.

4. Lighting

Pelargonium is native to South Africa and likes sunny, warm and well-ventilated environmental conditions. Under the condition that the light is not too strong in spring and early summer, the flowerpot can be placed in a place with sufficient light to receive sufficient light, but in the hot season of midsummer and early autumn, it is appropriate to put it in a shaded place to avoid strong light, otherwise, the branches and leaves will be burned.

5. Pruning

In order to make the plant beautiful and more flowering, thinning and pruning can be carried out if the plant grows too vigorously in spring. Cut off the residual flowers and over-dense branches in time after flowering. The dormant period is also pruned once, the yellowed old leaves are cut off, the overdense branches are thinned, and the overlong branches are cut short, so that after the dormant period, new branches are produced and buds continue to blossom. In addition, the geranium itself has a special smell and rarely suffers from insect pests. Therefore, there is no need for prevention and control.
