How can I raise asparagus well?

Cultivation methods and matters needing attention of asparagus

1, ecological habits

Asparagus likes warm, humid or semi-cool places. Not cold and drought-tolerant, it should be planted in loose sandy loam and artificial medium, and avoid sun exposure.

2. Cultivation points

Put asparagus in a ventilated and semi-cool place and control watering. You can spray the leaves of wine with water at room temperature every week. Water should be wet and dry. If it is too dry, the leaves will turn yellow, and if it is too wet, the leaves will rot. When the weather is dry, it is necessary to spray water around leaves and flowerpots to keep the air.

Humidity. Water should be poured thoroughly, and it is advisable not to accumulate water. There is no need to fertilize too frequently and too thick during the growing period. Generally, fertilizer is applied once every 10 day in spring and autumn. When the temperature is high in summer, fertilization should be stopped to avoid root rot. Stop fertilizing in winter and put it in a south-facing room with soft light. The basin soil is required to be loose and well drained. Generally, change pots 1 time every two years to protect the original protective soil of plants.

3. Breeding method

The roots of asparagus can be divided into 23 plants, which are planted in pots when changing pots in spring. When dividing plants, separate young plants from young plants by hand, and pay attention to minimize root damage. If the root is damaged, apply a layer to the wound. After the ashes are dried, they are planted in pots to reduce bacterial infection. Leave it in the shade for a few days after serving. The suitable sowing and breeding time is from March to April in spring. Cover the seedlings with thin soil, and the soil in the basin should be loose. After sowing, enough water should be poured to make them permeable and the soil should be kept moist. When the seedlings grow to five leaves, they can be transplanted into flowerpots.

Key points of asparagus maintenance

Potted soil

Asparagus is suitable for growing in warm and humid soil with rich rotten branches and good drainage. Asparagus is afraid of smoke. If it encounters toxic gas, its branches and leaves will turn yellow easily. Therefore, attention should be paid to keeping the environment clean during maintenance. Asparagus will enrich the soil. If there is no soil replacement and fertilization for a long time, the nutrient supply will be short and the branches and leaves will turn yellow. At this time, it is necessary to water the decomposed dilute liquid fertilizer or compound fertilizer once a week, and water the soil in time to make it turn from yellow to green quickly. If the fertilizer is too thick or does not decompose, it is easy to cause "watering the roots", resulting in dry leaves and falling off. At this time, it is necessary to pour out the pot to remove fertilizer, make the soil into a ball with clear water and put on new culture soil.

water

If potted asparagus is watered too much, the soil is too sticky and the drainage is not smooth, the leaves of asparagus will turn yellow and fall off.

The influence of longevity. Generally, you should wait until the soil in the basin is dry before watering. Wash less water in spring and autumn, insist on not doing it, and control watering in winter. Too much watering and too wet pot soil can easily cause root rot and yellow leaves to fall off. When watering, pay attention to the water temperature as close as possible to the surrounding temperature to reduce the stimulation of the root system caused by the discomfort of the water temperature. When the weather is hot and dry, spray the leaves with water.

Fertilize soil or land

Asparagus is not a good fertilizer plant, but it cannot be short of fertilizer. Potted asparagus is limited by potted soil, so it must be supplemented with nutrients in time to meet its growth requirements. Asparagus should be fertilized frequently, and never apply thick fertilizer, otherwise it will easily lead to yellowing of branches and leaves. In spring and summer growing season, nitrogen fertilizer is king. The decomposed dilute liquid fertilizer can be applied 1 time a month. When modeling plants, fertilization should be properly controlled to avoid growing too fast and affecting the appearance of plants.

illuminate

Asparagus cultivation should not be exposed to the hot sun, and should be placed in a cool and ventilated place in hot summer and autumn. I am afraid of both wind and rain during flowering. At this time, we should pay attention to good ventilation, otherwise it will lead to falling flowers and no results. When potted, it is suitable to put potted plants outdoors to receive sunlight on sunny days, which is beneficial to their photosynthesis.

temperature

The environmental temperature of potted asparagus in winter should be kept above 5℃ to avoid freezing.

breeding method

Asparagus is generally propagated by sowing or dividing plants. Spring should be sown in March-April, and it can germinate 30-40 days after sowing. It can blossom and bear fruit after 4 years of normal growth. 35-year-old asparagus can be propagated by plants, but it is necessary to cut off the joint of roots with a sharp knife when propagating by plants, otherwise the damaged implants will recover slowly and the shape will be uneven, which will affect the ornamental effect.

The moral of asparagus

Asparagus is a symbol of eternity, a friend's childlike heart, and will never change. If it is really a wedding flower, it is a symbol of wedding smoke and everlasting love happiness and sweetness. Asparagus can be a symbol of eternal love and a symbol of long-term pure friendship. Putting asparagus bonsai at home is also a symbol of a beautiful family, harmonious and beautiful.
