What is the old rotten root of Eupatorium adenophorum? When watering orchids at ordinary times, water accumulates in the buds of orchids for too long, which makes the buds rot, or when taking orchids in the sun at ordinary times, it rains carelessly and forgets to take them back, which leads to rotten roots of orchids. Moreover, if the orchid doesn't absorb enough sunlight on weekdays, or the temperature is too low, there will be water in the basin, which the orchid can't absorb.
How to deal with root rot of Euonymus japonicus? Check the roots. Buxus macrophylla likes humid growing environment, so it needs to keep enough moisture during the curing period. However, if excessive watering causes water accumulation, Buxus macrophylla will rot. At this time, it is necessary to take it out of the soil, wash the soil at the roots and check the rotten roots.
Pruning rotten roots If the rotten roots of Eupatorium adenophorum are not particularly serious, then we just need to cut off all the rotten roots.

Soil replacement and replanting. After the root wound of Eupatorium adenophorum is dry, we can replant it. When planting, we'd better replace the original soil, because there are already rotten roots in the original soil, and a lot of bacteria will remain in the soil. If we continue to use it, it will easily lead to root rot of Eupatorium adenophorum again.
After planting Eupatorium adenophorum, it is necessary to control the water quantity, because Eupatorium adenophorum has just trimmed its roots and its water absorption capacity has not recovered. If it is watered in large quantities, it will easily lead to water accumulation and root rot of Eupatorium adenophorum.
In the cultivation method of Eupatorium odoratum 1, the roots of Eupatorium odoratum are thick and long, and the roots need to be fully loose and breathable, so potted Eupatorium odoratum with few leaves should use medium-sized flowerpots, which can provide suitable growth space for the roots.

Gently scrape off the topsoil, you can see the semi-dry soil, which is the most suitable humidity for orchid growth.
4. Fertilizing hardwood is a kind of plant that likes fertilizer and can be planted on humus-rich flower soil. When planting, it is best to prepare a layer of base fertilizer in advance to ensure adequate growth environment. During cultivation, some liquid fertilizers can be sprayed on the leaves of Eupatorium odoratum to promote its growth and development.
5. Soft and fertile soil is the best way to cultivate hard-leaved orchids. Hard orchids have long roots and are very strong. Therefore, the looseness and permeability of soil become necessary living conditions. In order to ensure the normal growth of roots, try to choose a bigger pot to grow. Can provide enough growth space for the root system.
