How to raise asparagus and how to make its leaves yellow?

How to raise asparagus likes to be warm, and it should be sunny in winter. If you put it in a place where no light can be seen for a long time in winter, poor ventilation or cold will easily lead to withered and yellow branches and leaves. At this time, it can be transferred to a warm place with sunshine, and the room temperature can be maintained between 12 ℃ and 18 ℃. Proper control of watering can gradually return to normal.

Asparagus is afraid of smoke and dust, and if it encounters poisonous gases, its branches and leaves are prone to yellowing. For this reason, attention should be paid to putting it in a clean environment during maintenance. Asparagus should be fertile soil, if there is no soil change for a long time, nutrients are in short supply, there will be branches and leaves yellowing phenomenon. At this time, it is necessary to pour mature thin liquid fertilizer or compound chemical fertilizer once a week, and water and loosen the soil in time, so that it can change from yellow to green soon. If the fertilizer is too thick or unmature fertilizer is applied, it is easy to cause "watering the root", resulting in the drying and shedding of the leaves. At this time, it is necessary to pour the pot to remove the fertilizer, irrigate the soil block with clean water, and then change it into the new culture soil.

Asparagus likes semi-shade and avoids strong light. If it is maintained in direct sunlight in summer, it is very easy to cause withered and yellow branches and leaves. At this time, the flowerpot should be moved to a cool place, often spray water to the branches and leaves, increase air humidity, when the injury is light, most can be restored as before.

How to raise asparagus like wet, afraid of drought, avoid too wet and waterlogging, and have strict requirements on soil and moisture. Mastering appropriate basin soil moisture is a key to the daily maintenance of asparagus. Usually, such as too much watering, resulting in long-term wet or stagnant water on the basin, will cause poor root growth, and then cause rotten roots. The results showed that the branches and leaves grew at first, then the yellow branches and leaves gradually withered and fallen leaves, the new buds withered in the middle, and the vines for more than three years showed a large amount of falling flowers and seeds, which could lead to the death of the whole plant. If you water too little, the pot will be too dry, resulting in yellow leaves and withered shoots, shedding twigs, withered bodies, buds and flowers at the same time. If it is found that the basin is too wet, do not continue watering. By loosening the soil, changing the basin and dredging the bottom hole, the excess water should be dispersed quickly.
