How to water Jianlan (how often) how to fertilize Jianlan

Jianlan must be no stranger to many people. We can often see it in our life. It is a highly ornamental plant. Now there are many people who cultivate Jianlan, but many people will be distressed by the problem of fertilizer and water when they are farmed. In fact, as long as they master the skills, it is still very simple. Next, let's study together.

How to water Jianlan (how often)

The main results are as follows: 1. The watering time of the same basin will be different in different seasons. during the Spring Festival, the humidity is high, the temperature is low, the plants are growing, the moisture in the basin soil decreases slowly, the watering time is relatively longer, and the plants grow vigorously with low humidity and high temperature in summer. the moisture in the basin soil decreases quickly, and the watering time is shorter. So a few days of watering is a difficult answer.

2. When Jianlan is watering, it shows that the basin surface soil has a sense of whitening or cracks, and when the basin surface soil is wet, it means that the basin soil is still very wet and can not be watered, and it is easy to cause rotten roots to die after watering. In this way, it is easy to judge the watering time, and it is not easy to cause rotten roots after watering. This watering method is more suitable and is not easy to cause the problem of watering rotten roots.

How to apply fertilizer to Jianlan

1. Budding fertilizer: generally carried out in late spring and early summer, granular fertilizer is used twice first, and fertilizer outside the root is sampled (far away from the root), mainly nitrogen and potassium fertilizer, which can promote the emergence of stems and leaves on the ground and promote the growth of underground roots. Only when the roots are strong, can they provide a continuous supply of nutrients for the stems and leaves.

2. Germination fertilizer: in late summer and early autumn, new buds have already grown leaves. In order to promote the growth of new buds, we should supplement nitrogen fertilizer and adhere to the principle of frequent application of thin fertilizer. After the new buds were unfolded, the new buds were changed to potassium fertilizer, which could promote the rejuvenation of the seedlings. The leaves were sprayed with potassium dinitrogen phosphate solution once a week to promote the growth of leaves. During this period, fertilization is willing to promote stout branches, thick leaves, fresh and tender leaves and luxuriant plants.

3. Flower-promoting fertilizer: before flowering, when the new branches and leaves are no longer growing, they will enter the flower bud differentiation period. At this time, phosphate fertilizer should be used as the main fertilizer, extra-root fertilization should be carried out once a week, and chemicals should be sprayed to promote flower bud growth.

4. Dormant fertilizer: in late autumn and early winter, the Beginning of Winter will type the dormancy period after Jianlan. Foliar fertilization is generally applied at this time, once every 15-20 days, to ensure that Jianlan can survive the winter safely, and can also improve the germination rate of the coming spring.

How does Jian Lan propagate separately?

The main results are as follows: 1. The reproduction mode of Jianlan is ramet propagation, which can be propagated in spring and autumn, and can be propagated every three years.

2. Jianlan plants with strong growth and dense pseudocorms should be selected when dividing plants, and irrigation should be reduced before splitting.

3. When putting on the basin after ramet, you should first cover the broken tiles on the hole at the bottom of the basin, and then cover it with coarse stones, accounting for about 1/5 to 1/4 of the depth of the flowerpot, and then put on the thicker granular soil or a small amount of fine soil. after that, it is planted with sandy soil rich in replication, so that the false corms are just buried in the soil, and the edge of the flowerpot should retain two centimeters along the mouth, and cover it with fine stones or emerald grass. Note that each clump retains at least 5 connected pseudocorms after ramet.

4. Finally, pour water thoroughly and put it in a cool place for about 10 to 15 days. During this period, the soil should be kept moist, and then the amount of water should be gradually reduced and normal maintenance should be carried out.

What if the leaves of Jianlan withered?

1. The humidity of the growing environment is too low. If the humidity in the air is too low, the leaves of this plant will begin to become rough, and then become dim and dull. This is the phenomenon of withered leaves caused by too dry air. It is better to spray water on the leaf surface.

2. The lighting should be reasonable. This kind of plant likes to grow in shady places and is afraid of too much light, so never put it in a place where the light can directly reach it. The position should be adjusted in time.

3. The temperature of the growing environment should be comfortable. This plant is suitable for mild temperatures. In winter, the leaves are likely to wither because the temperature is too low or frozen; in summer, the heat is too high and the base of the leaves begins to rot, causing withered leaves. It is best to grow in places where the temperature reaches 20 to 35 degrees.

Jianlan must pay attention to the amount when watering and fertilizing, too much or too little is not conducive to its growth. If you want to build an orchid to grow well, it is necessary to breed, in which ramet reproduction is the most common. There are some detailed introductions above. I hope it can be helpful to you.
