How does fertilization apply? What are the fertilization methods and precautions for Gardenia? In the process of curing, gardenia flowers grow slowly, the branches are thin, and when frequent topdressing is needed, it indicates that the base fertilizer is insufficient during planting. Before planting gardenia, add organic fertilizer (soiled animal manure, cake fertilizer) to the soil and mix it evenly with the soil. In fact, most families raise flowers, the number of fertilization is small, and they are not often taken care of. In order to save trouble, agricultural scientists have developed lazy fertilizers - slow release fertilizers.
When the fertilizer is applied to the pot, the fertility in the fertilizer will be slowly released, there is no need to worry, and the fertilization excessively damages the plant. However, fertilization was stopped after October and during flowering.
top dressing
From April to October, except for the flowering period, the fertilizer is applied once a month. Potassium dihydrogen phosphate was sprayed once a week starting in April, until the buds appeared on most of the branches of gardenia.
After buds, it can be used to enhance the plant's resistance to stress by planting twice with potassium dihydrogen phosphate, and promote plant flowers and flowers. But as long as the flower buds are cracked and white, stop fertilizing.
Pot fertilization
If the basin is changed, the plant should be placed in a cool place to cool the pot, and then fertilize after the slow pot period.
Precautions
It is necessary to loosen the soil one day before fertilization, which is beneficial to the nutrient absorption of the plant and achieve the best fertilizer efficiency; watering the next day after fertilization, avoiding the accumulation of fertilizer in the soil and causing fertilizer damage.
Fertilization needs to keep in mind these time points: fertilization after spring, no application after autumn; flower buds are currently fertilized, buds are not applied when they are cracked; fertilization is applied on sunny days before rain, no application after rain; fertilization when soil is dry, not applied when wet; Fertilizer application, concentrated fertilizer do not apply; apply flowers before flowering, do not apply when flowering; apply fertilizer in the morning and evening, no application at noon; strong seedlings, weak seedlings.
In the culture soil, 3% decomposed cake fertilizer can be added as the base fertilizer. During the growing season, the eucalyptus oil made from cake sulphate and ferrous sulphate is poured once a week, and the 0.1% potassium dihydrogen phosphate aqueous solution is poured once in the bud period, and the fertilizer is stopped when the temperature is above 35 ° C in the summer and 15 ° C in the autumn. .
In the flowers, Gardenia is undoubtedly a flower that is familiar to everyone. People like to farm at home, but many people do not know much about the fertilization method of gardenia, which causes many problems in the breeding process. Here is a brief introduction to how to apply fertilization and what fertilizer to apply.
Gardenia fertilization method
- 1, gardenia should be cooked with bean cake, sesame sauce, peanut bran and other fertilizers, fermented and fermented can be acidic, but must be applied more than thin fertilizer, avoid heavy fertilizer, fat, do not fertilize during hibernation.
- 2, gardenia should stop watering before fertilization, watering should be poured when fertilizing.
- 3, scorpion peanuts for a long time, the appropriate amount of fertilizer when flowering, add a fertilizer after the flower.
- 4, gardenia planting less than three years, should not be applied to manure. Excessive application of nitrogen fertilizer will result in thick branches, large leaves, and thick green, but not flowering. In the absence of phosphorus and potassium fertilizer, there will also be no flowering or buds withered and shedding.
Gardenia fertilization time
Gardenia needs a reasonable supplement of fertilizer during the growth period. Apply a decomposed human excrement or cake fertilizer every 10 days or so, stop watering one day before fertilization, and pour one water at the same time. Fertilization stopped in mid-September. In adult plants, hemp slag is added once in mid-June and mid-August, 0.5-1 for each time. After crushing, it is thoroughly mixed with topsoil.
Gardenia fertilization considerations
Gardenia flowers are fat, but you can't add too much fertilizer at one time. You must use thin fertilizers and do not greedy things. Otherwise, it will cause thick branches, big leaves and thick green, and you will lose its own appreciation. .
The reason why gardenia flowers do not bloom
- 1. Improper water and fertilizer. Once the water and fertilizer are excessive, it will cause the plants to grow up. If there is not enough nutrients in reproductive growth, it will affect the formation of flower buds, resulting in no flowering or flowering, and some will open and even fall off immediately. Pay special attention to the combination of phosphorus and potassium fertilizer during flower bud differentiation, such as 0.2% potassium dihydrogen phosphate solution, which is conducive to the formation of flower buds and pregnant buds; seedling.
- 2, the light is not suitable, the gardenia flowers are yin, pay special attention to the summer too strong and the winter too weak light, too strong and too weak will affect the flowering of Gardenia.
- 3, the soil contains high alkali, gardenia likes acidic soil, cultivated gardenia soil with high salt and alkali, will cause yellowing of the plant, and ultimately affect flowering.
- 4, no pruning and shaping, gardenia branches are messy, a large number of miscellaneous branches consume a lot of nutrients and branches are too dense, affecting photosynthesis, are important reasons for not blooming.
- 5, the pests and diseases are serious, I believe that everyone can understand that the serious pests and diseases will inevitably lead to falling flowers.
