Maintenance of Cymbidium grandiflora, how to maintain Cymbidium grandiflora?

1. Flower pot selection: If you want to breed large-flowered orchids, you need to choose pots with good air permeability to breed, because large-flowered orchids cannot accumulate water, and once the water accumulates, it will lead to rotten roots.

2. Soil requirements: Cymbidium grandiflora has certain requirements for soil, must be loose, we generally have better choose self-made, use humus soil, garden soil, sandy soil, according to the ratio of 2:2:4 for mixed use.

3. Sunlight demand: The demand for sunlight is relatively limited, we generally only need to give it the morning sunlight, and at other times, we can put it in the astigmatism to breed.

4. Reasonable watering: the demand for water is limited, we must not water more, choose to water every 2 days in spring and autumn, several times a day in summer, and water once in about half a month in winter.

5. Reasonable fertilization: the demand for water is limited, we must not water more, choose to water every 2 days in spring and autumn, several times a day in summer, and water once in about half a month in winter.

6. Pruning branches and leaves: In the process of growth, there will be some wilted branches and leaves, we need to prune them off in time, generally if we are afraid of growing too tall, we also need to carry out topping treatment.

1. Temperature: The suitable temperature for the growth of Cymbidium macroflora is 10 30, and it likes high temperature during the day, low temperature at night, and a large temperature difference (more than 8).

2. Light: The most suitable light intensity of Cymbidium grandiflora is 230,000 lux (note: medium to strong), compared with most orchids, Cymbidium grandiflora prefers sunlight.

3. Watering and humidity: Cymbidium grandiflora is a terrestrial orchid, which likes the environment of moist roots without water accumulation, and requires high humidity during the growth period, 75 85%, about 50% in the dormant period, and 55 65% in the flowering period.

4. Fertilization: small and medium-sized seedlings need high potassium fertilizer, the ratio of n, p, k is 1:1:2 3, and medium and large seedlings need to increase the proportion of p, and organic fertilizer is the mainstay, supplemented by foliar fertilization.

5. Pests and diseases: the most serious disease of Cymbidium grandiflora is anthracnose, and others include blight, gray mold, stem rot, root rot, etc., which can be controlled by Dasheng M-45, 2000, mancozeb, etc. The insect pests of Cymbidium grandiflora mainly include scale insects and red spiders, which can be treated with panacea and quick culling, and dicofol and mite effect can be used to treat red spiders.

The most suitable temperature for the flowering period of the orchid is 5-15 degrees.

When maintaining potted plants, humus, river sand and base fertilizer can be mixed into nutrient soil for planting. During the maintenance of the orchid, it is necessary to water every 5 7 days to ensure that the soil is in a slightly moist state, and in addition, it is necessary to apply a phosphorus and potassium compound fee every 20 days or so during the growth period of the orchid to supplement nutrition.

When maintaining the orchid, you first need to choose the right soil. It is suitable for growing in loose and fertile soil with good drainage, and when cultivating Orchid, it can be planted with a mixture of humus, river sand and basal fertilizer in nutrient soil. In addition, the soil needs to be sterilized at high temperature before potting to avoid diseases during the growth of the plants.

During the maintenance of the orchid, it is necessary to ensure sufficient water, which is suitable for growing in a humid environment, and needs to be watered every 3 days during the growth period of the orchid, and once a day in summer. In winter, the growth of the orchid is relatively slow, and it needs to be watered every 5 to 7 days to ensure that the soil is in a slightly moist state.

During the growth period of the orchid, it is necessary to ensure that the nutrients are sufficient to make it grow vigorously. During the growth period of Cymbidium orchid, it is necessary to water nitrogen, phosphorus and potassium compound fertilizer every 20 days or so to promote the growth of branches of C. grandiflora. Note that when fertilizing, it should be carried out together with watering to avoid root burning due to high fertilizer concentration.

It is suitable to grow in a sunny environment, and it can be placed in a sunny location for daily maintenance. In addition, in summer, it needs to be moved to a ventilated and cool location for maintenance to avoid high temperature causing burns on the leaves.
