In fact, these reasons are mainly caused by improper cultivation in peacetime. The following editor has sorted out some solutions, hoping to be helpful to you.

The cause of the long spot of Cymbidium and its solution

1. Unreasonable fertilization

When we are in the process of fertilizing the orchid, for example, the fertilizer needed by the orchid is mainly nitrogen, phosphorus and potassium fertilizer, but if there is too little fertilization, unreasonable fertilization, adding thick fertilizer or adding raw fertilizer, it will lead to the phenomenon of long spots in the orchid.

Solution: therefore, in order to prevent the phenomenon of magnolia spots, reasonable measures should be taken in fertilization. For example, rotten liquid fertilizer can be applied during the growth period, mainly nitrogen fertilizer and rotten cake fertilizer. Fertilizer based on phosphorus and potassium fertilizer can be applied before flowering. The foliar fertilizer is mainly potassium dihydrogen phosphate with low concentration, which can ensure the normal growth of Cymbidium.

2. Improper soil

A good soil environment can make the orchid grow more fully, if in the culture, there is no effective loosening of the soil for a long time, resulting in basin soil consolidation, the root system can not breathe effectively, and finally directly lead to the phenomenon of long spots. There is also a long-term failure to effectively change the basin, the final result will also lead to the phenomenon of gentleman orchid spots.

Solution: for the phenomenon caused by this reason, first of all, we should reasonably loosen the soil at regular intervals, so that keeping the basin soil loose is conducive to root respiration and growth, so that there will not be long spots. In addition, the orchid needs to change the basin almost every 1-2 years, so the new nutrient substrate is conducive to the root growth and promote the luxuriant green branches and leaves.

3. Caused by diseases and insect pests

One of the main reasons for the occurrence of long spots in Cymbidium is the occurrence of diseases. for example, some leaf spots often occur in Cymbidium. At the time of onset, there are oval, long, light reddish brown spots on the leaves and green circles around them. with the expansion of the disease showed irregular large patches, the disease spots produced black spots, and finally led to death and shedding.

Solution: first of all, in the early stage of the disease, we should remove the diseased leaves in time, and then put them in a ventilated environment to maintain appropriate light and temperature. If the condition is relatively large, you can spray medicine in time for treatment. For example, 50% topiramate can be used 1000 times and sprayed once a week.
