The latest culture method of geranium

Pelargonium is a perennial herb, native to Morocco, Algeria, France, Egypt and other countries. It was introduced by Kunming plants in 1962. After successful cultivation in Kunming, Yuxi, Shiping, Binchuan and other places, it has been cultivated in various gardens. It is widely popular because of its volatile aroma and can be used to make essential oils. Let's take a look at the cultivation methods of Pelargonium fragrans.

Growth habits of Pelargonium fragrans

Pelargonium fragrans likes temperature and drought tolerance, is not cold-resistant, is afraid of waterlogging, and does not have high requirements for water. It is suitable to grow in neutral or weakly alkaline soil, and sufficient sunshine is needed for growth. When selecting cultivation areas, sufficient sunshine should be given priority to. Rich sandy or loam soil with deep, loose texture and rich humus is required, while heavy soil and low-lying land with poor drainage are not suitable for cultivation. The suitable planting range should be below 1800 meters above sea level and the frost period is less than 10 days.

Propagation method of Pelargonium

Pelargonium fragrans is mainly propagated by cuttings, and it can also be sown or tissue cultured. The stout branches with terminal buds were cut in April, May or September and October, and the length was 5cm to 8cm. After the cut was dried, the cuttings were cut and 3 terminal buds were retained. Shade, moisturizing, about 15-20 days can take root and survive. When cultivating new varieties, artificial pollination is often used. At that time, seeds are collected and sown, and seedlings germinate in 7-10 days at a temperature of 20 ℃.

Culture method of incense leaf geranium

1. Soil: the 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: the geranium is 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 addition to applying sufficient basal fertilizer, thin liquid fertilizer can be applied every 7 to 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. Three to five days before fertilization, little or no watering, watering when the basin soil is dry, is more beneficial to root absorption.

4. Lighting: the geranium is native to South Africa and likes the environmental conditions with plenty of sunshine, warmth and good ventilation. 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 shape beautiful and bloom more, if the plant grows too vigorously in spring, it can be pruned, cut off the residual flowers and over-dense branches in time after flowering, prune once during the dormant period, cut off the yellowing old leaves, remove the overdense branches, and cut short the over-long branches to prepare for the emergence of new branches after the dormant period and continue to bloom buds. In addition, the geranium itself has a special smell and rarely suffers from insect pests, so there is no need for control.
