2, too much watering, pot soil is too wet, easy to cause root rot, too little watering, it will lead to dead leaves and yellow leaves. Therefore, in the process of watering, it is necessary to look at the weather, growth and the dryness and wetness of the basin soil, so as not to water it, but to water it thoroughly.
Asparagus is not fat, but it can't be short of fat. Due to the limitation of potted soil, asparagus cultivation must be supplemented with nutrients in time to meet the growth requirements. In the process of asparagus fertilization, it is necessary to make more fertilizer and less fertilizer, and not to apply thick fertilizer, otherwise it will cause yellow leaves.
4. Asparagus planting should not be exposed in the hot sun. In hot season, it should be placed in a cool and ventilated place. In winter, potted asparagus is moved to a sunny place indoors to prevent freezing injury.
5. When the growth position of small leaflike branches on the main branch is not ideal or missing for some reason, short cutting can be carried out at the appropriate position of the main branch to force the hidden buds to germinate.
note:
1. The shaping of asparagus must be combined with fertilizer control and water control. That is, at room temperature 15- 18℃, water once a week to keep the soil moist. Not fertilized or less fertilized.
2. Change the pot once a year, increasing year by year. If you don't change the big pot, you can turn it over and remove some small roots, put in new soil, plant the original pot, pay attention to updating the stems and branches at ordinary times, and remove the old and sick stems and branches at any time.
3. Asparagus is afraid of smoke, indoor smoke will cause its yellow leaves to fall off. For example, indoor smoking will have an impact on asparagus leaves.
