Fertilization techniques and methods for edible mushrooms, and the reasons why Clivia (Clivia miniata) does not bloom or blooms sparsely

Why does Clivia not bloom? Many orchid enthusiasts, including some non-professional orchid-growing neighbors and classmates around me, often encounter a problem in the process of growing orchids: Clivia that has been grown for many years does not bloom or blooms very rarely! Why is that?? Recently I have learned some knowledge about this from various sources! Let me share it with you here: A normally growing Clivia, when it grows to about 3 years and its leaves reach a dozen or so, can shoot up a scape and bloom. Well-grown ones can even bloom in less than two years, yet many Clivia still do not bloom even after more than 4 years. The main reasons are: 1. Poor soil. Clivia likes acidic soil, with a pH between 6 and 7. Above 7 it becomes alkaline, and both its growth and flowering will be affected, so when growing Clivia you must use fertile, acidic, loose, breathable, slightly acidic culture soil! For situations where the soil is weakly alkaline or alkaline fertilizer has been applied, you can water it with ferrous sulfate or edible rice vinegar diluted in water, but it must not be too concentrated! (It must be rice vinegar, and not blended white vinegar or vinegar essence.) 2. Unsuitable nutrition. Clivia has different requirements for various nutrients at different growth stages. During the growth period it mainly needs nitrogen fertilizer and potassium fertilizer. Once it enters the reproductive period, if there is too much nitrogen fertilizer and a lack of phosphorus fertilizer, it will cause the plant to grow excessively and the flower buds will be unable to differentiate! This is also a main reason why many Clivia look very vigorous but do not bloom! 3. Water imbalance. The cells inside Clivia must contain a certain amount of water to carry out normal life activities, and at the same time the nutrients in the soil must be dissolved by water before they can be absorbed by Clivia's root hairs. Therefore, watering must be reasonable; too much or too little will directly affect the growth and development of Clivia, hinder flower bud differentiation, and make it difficult for the plant to bloom! 4. Temperature and light. Clivia generally stops growing when the temperature is below 10°C or above 30°C, so if the winter temperature is too low, it is not easy for it to bloom. If the sunshine duration in summer is too long, first it is easy to sunburn, and second it is easy to cause the leaves to grow excessively, that is, "legging out", which also affects scape formation and flowering. In fact, growing Clivia is not difficult. As long as you follow Clivia's growth patterns and care for it carefully, it can bloom at least once a year, and many can shoot two scapes and bloom twice! Some varieties of Clivia can even shoot more than 5 to 6 scapes in a year.
