How to raise Umbelmoschus mandshurica the breeding methods and matters needing attention

Umbrella grass is what we often call water bamboo, is a kind of waterway growth plant. Parasol grass is a kind of plant introduced and cultivated from abroad in our country. At present, it is distributed in many parts of our country. Umbrella grass has a certain ornamental, so there are many people who want to raise it, but when breeding, there are a lot of places that need to be paid attention to.

How to raise Umbrella grass

1. Select a low plant (about 15-20 cm high) with 5-7 branches as a clump of muddy seedlings, wash the soil from the root of the parasol grass with clean water and put it into a water basin.

2. Press the root of the parasol grass with sand or stone eggs, make it fixed and lodge, and add clear water to the root of the submerged plant.

3. Never move outside in winter to prevent frost damage. Change warm water every half a month, or add a little less water in the basin.

4. Autumn is the growing period of Umbrella grass, when new branches and leaves grow, the old branches are withered and yellow and can be cut off. Change the water every 3-5 days, or add a little more water when there is less water in the basin.

5. It is better to add inorganic fertilizer 1-2 times a month to the basin, which can be dwarfed and green.

Culture methods and matters needing attention of Upland Grass

1. Culture methods:

1. Light management. If you are afraid of bright light, you need to keep it in the semi-shade or give it 70% shade. For indoor maintenance, put it in a brightly lit place as far as possible, and move to outdoor semi-shade or shade for a month every one or two months to accumulate nutrients and restore growth.

2. Humidity management. Like the high humid climate environment, the relative temperature of the air in the growing environment is 75-85%. When the air relative humidity is too low, the lower leaves yellowed and the upper leaf tips dried up.

3. Temperature management. The optimum growth temperature is 18 ℃ ~ 30 ℃, avoid cold frost, keep the overwintering temperature above 10 ℃, enter dormancy when the temperature drops below 4 ℃ in winter, and die of frostbite if the ambient temperature is close to 0 ℃.

2. points for attention:

During the dormant period in winter, the main task is to control fertilizer and water. Fertilizer and water management circulates according to the order of "Huabao"-clear water-clear water-"Huabao"-clear water-clear water. The interval period is about 7 to 10 days. Watering time is arranged as far as possible when the temperature is high at noon on a sunny day. Summer is watered in the morning or evening when the temperature is low, and plants are often sprayed.

The treatment method of yellowing leaves of Upland Grass

1. Strengthen the management. Parasol grass has a high demand for water, and it is necessary to change water frequently. It is better for tap water to precipitate first and then use it, and the precipitation time is 24 hours. The cultivation water and fertilizer of parasol grass is very important. Fertilizer is applied every 15 days or so, otherwise it is easy to be malnourished and cause the leaves to turn yellow. If the indoor temperature of raising parasol grass is suitable for its growth, it is necessary to bask in the sun properly.

2. Prune at the right time. The leaves of the parasol grass turned yellow at first because the roots were not fully developed, so just cut off the yellowing leaves. After raising the parasol grass for two years, it is necessary to clean up the old and dead roots and leave a little, so that the water bamboo can grow new roots. This is to prevent the leaves from yellowing and the stems from getting thinner.

Common diseases of Upland parasol and their control

1. Anthrax. Solution: spray the medicine in time when you get sick, and don't ignore the small scar on the leaf. The agent you can choose is methyl topiramate solution, which is sprayed once every 7 to 10 days. In addition, Bordeaux liquid is sprayed once a month.

2. Root rot. Solution: before planting parasol grass should do a good job of disinfection, timely ventilation, once a month with Bordeaux liquid root irrigation, kill eggs. For seriously infected plants, remove the pots in time, remove the rotten parts, replace them with new soil and pots, and replant them after disinfection.

In fact, the breeding method of parasol grass is not difficult, and it can be raised in combination with growth habits. In particular, the light and temperature must be in place. High summer temperature and low winter temperature are not conducive to its growth, so it is necessary to do a good job of protection. Timely prevention and control of diseases are needed in the later stage of culture.
