1. water: Bromus likes humid climate, and the growing environment requires the relative temperature of air to be 70 ~ 80%. If the relative humidity of the air is too low, the lower geranium leaves will turn yellow and fall off, and the upper leaves will be dull. Potted Bromus should always keep the soil moist, especially when it is hot in midsummer and the weather is dry, we should pay attention to watering and spraying water frequently to prevent the soil from drying.

2. Fertilization: During the growth period of Bromus, except in rainy season, pancake fertilizer water or manure water should be applied frequently to make the branches and leaves green and bright, and grow vigorously.

3. Temperature: Bromus fragrans is native to tropical areas and likes high temperature and high humidity environment, so it has strict requirements on winter temperature. When the ambient temperature is lower than 10℃, bromegrass will stop growing, and it is unsafe to overwinter in frost.

4. Lighting: Bromus species. I like semi-dark environment. Autumn, winter and spring require sufficient sunshine, and summer requires more than 50% shading. Indoor maintenance of Bromus inermis, as far as possible in bright places, such as living room, bedroom, study and other places with good lighting. After indoor maintenance for a period of time, you should move to a cool place outside for a period of time, so that it can grow well alternately.

5. Pruning: Bromus is very resistant to pruning. After autumn every year, you can prune it once, thinning out some over-dense branches and cutting off all kinds of messy branches or long branches to maintain a certain modeling posture and promote its lush foliage. Bromus species. Strong germination ability, should be picked in time, so that axillary buds germinate side branches. The more picking times, the denser the branches and leaves.

6. Turning pots: once every 2-3 years, before germination in February-March in spring. Combined with pot turning, root lifting treatment is carried out step by step. Replace the hardened old soil above 1B2, and fill the basin bottom with base fertilizer.

7. Pest control: Insect pests are the main harm to Bromus, and longicorn can be coated with a mixture of sulfur and stone, and scale insects can absorb juice and can be killed by manual washing.

Second, matters needing attention:

1. Water should be sufficient. Natural water such as river water, pond water and rainwater is better. If tap water is used, it needs to be stored for a day or two, so that the chlorine in it can run away and be reused. Do not use laundry water containing soap, oil and salt water.

2, fertilization should pay attention to excessive fertilization, branches and leaves are too long, lack of fertilizer makes branches thinner, leaves turn yellow, vulnerable to pests and diseases. Therefore, there should be principles for fertilization: new planting, new planting pots, new pots, and root damage should not be fertilized within one month. In spring and summer, potted trees must be fertilized in the peak season. After autumn, potted trees should be planted less when they grow slowly.

3, the pot soil is good. Bromus stumps used to grow in wild areas, with developed roots and drought resistance and waterlogging tolerance. Once they are dug up and planted in shallow pots, their growth conditions are limited. If they are not properly maintained, they are easy to die, so they should be taken care of. To choose flower mud with good drainage, it is best to thicken the basin soil during the curing period. Change the new soil every two years and apply some base fertilizer to protect the fertile soil, so that the pile landscape can grow normally.

Extended data:
