Cultivation methods and precautions of Gardenia: do not accumulate water to avoid rotten roots

The appearance of gardenia is beautiful, attractive and gives off a fresh smell. There are many kinds of it. Gardenia is native to China and cultivated in most parts of the country. The following section will introduce the cultivation methods of Gardenia in detail.

Cultivation method of Gardenia in pot: 1. Cultivation method of Gardenia in pot:

1. Pot soil: Gardenia is a typical acid flower, pot soil is suitable for 40% garden soil, 15% coarse sand, 30% manure soil, 15% rotten leaf soil.

2. Potting: potted Gardenia should be planted in late autumn, with soil ball.

3. Watering: gardenias like big water, the principle of watering is to dry through, watering with fermented rice washing water is the best. During the growth period, 0.2% ferrous sulfate or alum fertilizer water should be poured once every 7 to 10 days. The other time is every 3 days.

4. Light: it's best to put it under the shade of trees in summer where there is scattered light. In spring, summer and early autumn, you should often water and spray water on the leaves to keep the humidity. Put it in the sunshine in winter and keep it moist.

5. Change basin: if it is a pot gardenia, generally 1 to 2 years change basin once, mainly to prevent soil alkalization. When changing pots, pay attention to cutting off or cutting off the diseased roots and insect roots.

2、 Cultivation method of Gardenia in field

1. Breeding seedlings:

(1) Cutting method: cutting is divided into spring cutting and autumn cutting. Spring transplanting in late February and autumn transplanting in late September to late October are slightly different between the north and the south, but the survival rate between summer and autumn is the highest. The healthy and disease-free branches of the same year were selected for cutting. The length of the cuttings was about 15 cm. The lower leaves were removed and the upper 2-3 leaves were left. The cuttings were planted in sandy soil or pure sand matrix, and the depth of the cuttings was 2 / 3 of that of the cuttings. After transplanting, spray water frequently to keep the basin soil moist. The temperature is 20-25 ℃, and the air humidity is over 85%. After transplanting, it can take root about 30 days.

(2) Layering method: in April before and after the Qingming Festival or in the rainy season, select one-year robust branches from the three-year mother plant, which are 25-30cm long, to be layed and pulled to the ground where the branches are cut.

2. Site selection: it is better to select the acid and slightly acid soil with sunny but not easy to be directly exposed to the sun and exposed to the sun. The available places are hillside, Earth workshop, field edge, corner, etc.

3. Land preparation: dig a hole 4-6 feet away from the selected site according to the plant row (the soil quality can be larger, or smaller), the hole diameter is one foot, the depth is 0.8-1 feet, apply miscellaneous soil fertilizer, green fertilizer or human and animal dung water as the base fertilizer, and wait for planting after the soil is uniform.

4. Planting: the planting should be carried out in cloudy days from March to April. After the seedlings are unearthed, they should be planted in a timely manner without wind and sun. If they are transported far away, they should be grouted with yellow mud and covered with grass to keep moisture. Each hole should be planted with one plant, covered with soil and compacted.

5. Watering: after planting, the roots shall be watered in time, and the air and soil humidity shall be high, but water shall not be accumulated to avoid rotten roots.

6. Fertilization: gardenias are fond of fertilizer, so it is necessary to strengthen the management of fertilizer and water, and implement the principle of thin application and frequent application.

Gardenia planted in the field

Notes for Gardenia Cultivation: 1. The plastic pruning of gardenia is mostly carried out in early spring. After each shoot is plucked, the heart should be removed. One branch has three branches, forming a fast crown and many flowers. At the same time, cut the long branches in the dense bore. When the flowers of each season are about to wither, it is necessary to remove the remaining flowers in time, which is conducive to the flower bud differentiation of the next season, with more and better flowers.

2. After winter, gardenia can be put into dormancy for one month first, then moved into the room, and kept at room temperature above 18 ℃ by means of increasing temperature and light, which can promote Gardenia to bloom in winter and spring, and can be widely used as a variety of flower bouquet materials.

3. Gardenias in pots like to be wet. During their growth, they should keep the pot soil wet and pay attention to increase the air humidity. In summer, when the weather is hot and dry, water more; in spring and summer, spray the leaves with clear water in the morning and evening every day, and spray water on the ground around the basin to increase the air humidity; in winter, water less, but spray the branches and leaves frequently to keep the leaves clean.
