Chrysanthemum, as one of the traditional Chinese flowers, is deeply loved by people because of its diverse flowers and tenacious spirit. However, in the process of chrysanthemum maintenance, watering is a seemingly simple but rich part of the work. This paper will discuss the negative effects of excessive irrigation, such as root rot and disease breeding, and put forward scientific and reasonable watering strategies.
Moderate water needsAlthough chrysanthemums like moist environments, they are not waterlogg-tolerant. Its well-developed root system is suitable for growing in well-drained soil, and too much water can lead to a lack of oxygen in the soil, affecting the normal respiration of the roots.
Seasonal differencesDuring the vigorous growth period (spring to autumn), chrysanthemums have a high water demand, and in the dormant period of winter, the amount of watering should be reduced to avoid frostbite or bacterial infection of roots caused by low temperature and high humidity.
Breed differencesDifferent species of chrysanthemums have slightly different water requirements, for example, dwarf varieties such as ground cover chrysanthemum and monophyllum chrysanthemum are relatively drought tolerant, while cut chrysanthemums and potted chrysanthemums need to keep the soil slightly moist.
Trigger rotten rootsLong-term overwatering will reduce the air content in the soil, and the root system will not be able to respirate normally due to lack of oxygen, which will lead to necrosis of root cells and root rot. In severe cases, the whole plant wilts or even dies.
Promote the breeding of pests and diseasesThe excessively humid soil environment is easy to induce the occurrence of various fungal and bacterial diseases, such as blight, root rot, etc. At the same time, the humid environment is also conducive to the reproduction of nematodes, snails and other pests, which further endangers the health of chrysanthemums.
Affects the quality of floweringExcessive water not only affects the normal development of chrysanthemum roots, but also may cause nutrient absorption to be blocked, resulting in thin plant growth and poor flower bud differentiation, thereby reducing the quality and quantity of flowering.
Observe soil moistureBefore watering, observe the dryness of the soil surface and touch the lower layer of the soil with your hands to see if it is wet, and follow the principle of "see dry and wet", that is, the surface of the soil is slightly dry before watering appropriately.
Adjust the watering frequency seasonallyIn spring and summer, the number of watering can be increased appropriately to keep the soil slightly moist; It is gradually reduced in autumn and winter to avoid low temperature and high humidity.
Use drip irrigation or sprayingTry to use drip irrigation or spray watering to keep the soil moist and reduce the problem of soil compaction caused by direct watering.
Pay attention to drainage facilitiesWhen planting chrysanthemums, make sure that the container or planting site has a good drainage system to avoid standing water. Potted chrysanthemums should pay special attention to the bottom of the pot with sufficient drainage holes, and lay a layer of ceramsite or stones to enhance the drainage capacity.
Combined with fertilization managementWatering should be combined with fertilization, as far as possible in the morning and evening on sunny days, in order to facilitate plant absorption, and at the same time prevent fertilizer loss with a large amount of water.
Chrysanthemum watering should be moderately regulated according to its growth characteristics and environmental conditions to avoid root rot and disease breeding caused by excessive irrigation. Only by mastering the scientific and reasonable watering method can we effectively ensure the healthy growth of chrysanthemums and the scene of blooming flowers. Through meticulous observation and practice, every person who loves chrysanthemums will be able to cultivate chrysanthemums with outstanding demeanor. Chrysanthemums
