How to water and fertilize rice orchids, water and fertilizer management in four seasons and matters needing attention

Milan orchid is a very lovely plant, especially when it blooms, and the flowers are lovely and pleasant. But if you want orchids to grow well, you must master how to water and fertilize them. Watering should be based on the actual climate and fertilization should be based on the growth of orchids, so they are not quantitative.

First, the method of watering orchids 1, watering in spring

In spring, the weather gets warmer, the temperature rises, and orchids begin to enter the growth period. At this time, the required water will gradually increase, but it also depends on the weather and the dryness and wetness of the basin soil. Generally speaking, water is less on cloudy days, not on rainy days, and it is usually watered once every 2 ~ 3 days on sunny days.

2. Water in summer

Summer is the peak growth period of Michelia, and there is a great demand for water. We must keep enough water. Generally speaking, we should water it once a day. If the weather is too high, we can water it once in the morning and once in the evening. In addition to watering, it is also necessary to spray water mist on orchid plants to cool and moisturize.

3. Autumn water

In autumn, the temperature gets colder and the growth of orchids slows down. At this time, the amount of watering should be gradually reduced. After late autumn, water is usually poured once every 3 to 4 days. Don't pour too much water, which will lead to water accumulation and root rot in the basin.

4. Water in winter

When the temperature is low in winter, orchids will go into dormancy and the frequency of watering will be reduced. Generally, water is poured once every 10 ~ 15 days, as long as the soil in the basin is not excessively dry. When watering, you can choose to water at noon on a sunny day to narrow the temperature difference between soil and water and reduce the damage to plants.

Second, the fertilization method of Michelia 1, fertilization in spring and summer.

The flowering period of smiling face is very long, which can last from May to 65438+February. Spring and summer are the peak seasons for orchids to grow and bloom, and the required nutrients are also very large. During the growing season in spring, dilute nitrogen fertilizer can be applied every ten days to promote the growth of branches and leaves.

When Michelia enters the flowering stage, it is best to apply low nitrogen and high phosphorus and potassium compound fertilizer every 15 days, and spray potassium dihydrogen phosphate solution every 15 days to promote flower bud differentiation and improve the flowering quantity and quality of Michelia.

2. Fertilization in autumn and winter

Although Milan will bloom in autumn and winter, its growth rate is gradually slow, so it is necessary to reduce the number and dosage of fertilization appropriately to avoid burning roots. In autumn, phosphorus and potassium fertilizer should be properly supplemented, because continuous flowering of Michelia will consume a lot of nutrients. Fertilizer and water should be applied once every half month in early autumn, and it is best to change it to once a month in late autumn.

After winter, it is best not to fertilize orchids, because the temperature in winter is too low, orchids will enter a dormant period, at which time the absorption rate of water and fertilizer by their roots will be greatly reduced, and if fertilization is applied, it may cause root burning.

Three. Smiling 1 Maintenance precautions. Adequate lighting.

Know how to water and fertilize orchids, but also pay attention to some conservation matters. Milan likes light, so it is necessary to grow orchids in sunny places. Under the condition of sufficient light, the leaves of orchids can carry out enough photosynthesis, and the plants will become short and fat, with thick and bright leaves and sufficient nutrition, which will promote the differentiation of flower buds.

2. Change pots every year

The roots of orchids are relatively developed, so the soil for cultivating orchids must have sufficient nutrients. Therefore, it is best for orchids to change pots once a year. The flowerpots are slightly larger and the soil should be fertile and loose, so that orchids can grow better.

Step 3: Pick the heart and thin the branches

When the orchid grows to a certain height, it must be topped in time to prevent excessive growth. When the branches grow to 15 ~ 20 leaves, the heart should also be removed. In order to ensure flowering, all branches that are too dense, too long and thinner must be cut off, which can save nutrients and promote growth.

Conclusion: After reading the above contents, I believe everyone knows the method of watering and fertilizing in Milan. Water and fertilizer are the key to plant growth, and Milan will blossom naturally after reasonable control.
