How many years have gardenia been bought back and never blossom? Come and find out the cause and the solution.

Gardenia flowers are white and fragrant, so they are deeply loved by the flower-growing public. Gardenia has big leaf gardenia, lobular leaf gardenia, yellow gardenia, spotted leaf gardenia, water gardenia, four seasons gardenia and other varieties, among which four seasons gardenia can reproduce all year round, blossom more frequently, the temperature is suitable, can bloom all the year round. Our most common big-leaf gardenia can blossom in spring and autumn if properly maintained every year. If gardenia does not blossom after buying home for several years, it must be a problem with which link in breeding. There are many reasons why gardenia does not blossom. Let's analyze specifically what causes gardenia not to blossom.

1. There is not enough light. Gardenia likes light, in addition to avoid the summer high temperature period of strong direct light, other seasons should be given sufficient light. If you have a small courtyard at home, you'd better put it in a place with plenty of light. If it is balcony farming, it should also be placed outside the window where ventilation and light are better.

two。 The soil is not suitable. Gardenia jasminoides is a southern flower, which likes a slightly acidic soil with loose air permeability and good drainage. The configuration of rotten leaf soil, pine needle soil plus a small amount of garden soil and coarse sand can meet its growth needs. If the gardenia cultivated for several years do not blossom, it is necessary to check whether it is the cause of the soil, if the basin soil solidifies and change the soil in time. The northern flower friends can irrigate the roots of the plants with ferrous sulfate solution of 1RU 2000 every month to promote the synthesis of chlorophyll and prevent iron deficiency yellowing of leaves.

3. Fertilization is unreasonable. Long-term application of more nitrogen fertilizer and less phosphorus and potassium fertilizer will cause gardenia to grow leaves but not blossom. Some flower friends breed gardenia, only watering but not fertilizing, which is also the main reason for not blooming. During the budding period of Gardenia jasminoides in early spring, compound fertilizer with comprehensive nutrition of nitrogen, phosphorus and potassium was applied once, and then nitrogen fertilizer was applied twice to promote luxuriant branches and leaves, with an interval of about 10 days each time. The annual spring and summer season is the flowering period of Gardenia jasminoides. Apply more phosphorus and potassium fertilizer to reduce nitrogen intake. The application of rotten alum fertilizer and water once a week can not only keep the soil slightly acidic, but also conducive to flower bud differentiation. The root of the plant can also be irrigated with potassium dihydrogen phosphate solution every 10 days, combined with foliar spraying to promote bud formation. In order to prevent fertilizer from burning root in high temperature season in midsummer, thin organic liquid fertilizer can be applied.

4. It was not trimmed in time. The pruning of gardenia is actually very simple. If it is not blooming for a long time, the long branches, diseased branches and weak branches, including overdense branches, can be cut off together to promote the germination of more new branches and full plant shape. At the same time, the compound fertilizer with comprehensive nutrition of nitrogen, phosphorus and potassium is applied at the same time. After the new branches grow, they should be fertilized mainly with phosphorus and potassium fertilizer, combined with sufficient light to promote bud blooming.
