I raised asparagus at home, and I don't know what to do when the leaves turn yellow, nor do I know what caused this situation. So complaints and helplessness came unexpectedly. What should we do if the leaves of asparagus turn yellow? Today, the editor will introduce to you the reasons for the yellowing of asparagus leaves, prescribe the right medicine to the case, and see how we should deal with it.

1. The light is too strong

Asparagus likes semi-shade, avoid strong light, especially in summer to avoid direct sunlight, otherwise it will cause branches and leaves withered and yellow. The flowerpot should be moved to a cool place and water is often sprayed on the branches and leaves to increase air humidity.

2. Long-term shade

If asparagus is placed in a shady environment for a long time, the plant will grow weak and turn yellow. If the indoor light is weak, asparagus can be taken to a place with strong light every few days to increase photosynthesis.

3. Improper watering

Asparagus likes to be moist but afraid of waterlogging, so it should keep the basin soil dry and wet, and generally water the topsoil to make it moist. More water is easy to rot roots, less water is easy to dry tip, in the dry season should be more to spray water to the leaves.

4. Improper fertilization

If the application of topdressing is too thick or immature fertilizer is applied, it is easy to cause "root burning", resulting in leaf drying and shedding. On the contrary, if the potted soil is barren, the leaves will turn yellow due to lack of nutrients.

5. Poor winter management

Asparagus likes to be warm and sunny in winter. In winter, if you put it in a place where no light can be seen for a long time, poor ventilation or cold, it is easy to cause withered and yellow leaves. Generally, the room temperature should be no less than 12 ℃, and it should be placed near the south window, and watering should be controlled properly.

6. The position is not suitable.

If asparagus is placed next to heating and air conditioning for a long time, not only the leaves of the whole branch will turn yellow and fall off, but also the stem will dry up. Asparagus placed next to the computer TV for a long time will also cause the leaf tip to dry up, so it should be kept away from the air conditioning, heating, TV and computer during the maintenance of asparagus.

7. Harmful gas infection

Asparagus is afraid of smoke and dust, and if it encounters poisonous gases, its branches and leaves are prone to yellowing. In addition, if the plant is too large, the flowerpot is too small or damaged by insect pests such as shell insects, it will also cause branches and leaves to turn yellow, so the pot should be changed and controlled in time.

8. Infect diseases and insect pests

Once asparagus is infected with shell insects and other pests, it will also cause withered and yellow branches and leaves, so it should be controlled in time.

The above eight reasons will lead to the yellowing of asparagus leaves, we can according to their own breeding situation, and then prescribe the right medicine, presumably soon, your family's asparagus will also be able to restore vitality.
