Gardenia likes slightly acidic soil. Relatively speaking, the soil in the north is high in salt content and alkaline, which will make plants turn yellow and affect flowering.
Improvement measures: Before planting gardenia, treat the soil to be acidic. When maintaining, you can water plants with ferrous sulfate, or add a little vinegar when watering!
insufficient light
Gardenia likes sunshine, but it can't be illuminated by strong light. Improper illumination (too strong or too weak) will affect flowering.
Improvement measures: Gardenia can be placed on the balcony facing south at home, with at least four hours of light every day, and can be properly shaded when the light is strong in summer.
Insufficient fertilization
In the process of gardenia growth, too much water and fertilizer will make the plants grow in vain. If water and fertilizer are insufficient, plants will not get enough nutritional growth, and it is difficult to form flower buds, resulting in no or less flowering. Even if it blooms, it is easy to drop flowers and buds. In addition, insufficient phosphorus and potassium fertilizer and excessive nitrogen fertilizer will also affect the formation of flower buds.
Improvement measures: when gardenia is changed into pots, sufficient organic fertilizer can be added to the bottom of pots, dilute liquid fertilizer can be applied once a month during the growing period, and potassium dihydrogen phosphate can be sprayed once a week from April until it appears, which can promote flower bud differentiation.
I haven't trimmed it for a long time.
Gardenia branches are full of vitality. If you don't prune for a long time, the branches will be messy, the nutrition supply will be insufficient, and the flower buds will be difficult to differentiate. Therefore, plants lack nutrients and it is difficult to bloom.
Improvement measures: pruning in time during the growth period, cutting off long branches, overlapping branches and weak branches in time to promote flower bud differentiation.
Jasmine doesn't bloom, and the soil is alkaline.
Like gardenia, jasmine likes acidic soil. If the soil is alkaline, it will cause plants not to bloom.
Improvement measures: change the basin once a year or pour ferrous sulfate once every half a month. Apply more organic fertilizer and less chemical fertilizer.
insufficient light
Molly likes strong light. As the saying goes, "Jasmine won't die in the sun", when the light is insufficient, the leaves are small and thin, and it is difficult to form flower buds.
Improvement measures: put jasmine in sunny courtyard and balcony, let it see more sunshine, which is conducive to the germination of flower buds.
undernutrition
Jasmine is a flower with a strong preference for fertilizer, and it is difficult to bloom without fertilizer.
Improvement measures: summer comes into full bloom, and the decomposed dilute liquid fertilizer is topdressing once every 3 ~ 5 days; During the pregnancy and flowering period, phosphorus-based organic fertilizer solution, such as cake fertilizer, chicken pigeon manure, calcium superphosphate, bone meal, etc., should be applied once every three days. Or spraying 0.2% potassium dihydrogen phosphate 1 ~ 2 times will make the flowers colorful and fragrant.
