If gardenia flowers want to bloom quickly, we should pay attention to reasonable fertilization and water conservation, reasonable coring, and control bud shedding and pruning. After doing this, it is not a problem for gardenias to bloom quickly. Fertilize to keep water. Gardenia is suitable for acidic soil, and the cultivated soil should be composed of 70% slightly acidic sandy loam and 30% humus soil, and the soil PH should be controlled between 4.0 and 6.5. Gardenia is not a flower that loves fertilization very much, but it needs reasonable fertilization because of its long flowering period and vigorous growth. Generally, it is necessary to apply 1 time decomposed organic fertilizer every 1 day, stop watering every 1 day before fertilization, and water every1time after fertilization. In the dry season of summer and autumn, it can be combined with watering and topdressing available phosphorus and nitrogen fertilizer to make the leaves evergreen and beautiful. There is little or no fertilization after autumn, so there is a saying that fertilization cannot last until autumn. When the leaves turn Huang Shi, 1% ferrous sulfate can be used to pour the basin to make the leaves turn bright green. Gardenia likes humid air, so it should be watered properly during the growing period. When the soil turns white, you can water it. In midsummer and early autumn, water can be sprayed 2-3 times a day, but it is not advisable to water too much after germination to prevent root rot. A reasonable heart. After the new branches grow for three days, the core is removed to promote the germination of the branches. In order to prevent the lateral buds on these three nodes from sprouting and causing the crown to be too dense, 1-2 lateral buds at the base should be erased, leaving 1-2 secondary branches. In August, the secondary branches were cored again to prevent them from growing. After this enucleation, don't wipe the buds again, so that the axillary buds can fully develop. These lateral buds can branch and blossom next spring. Control the buds. During the bud incubation period from March to April, it is required that the air humidity is high, the soil is moist and there is no water accumulation, and the air circulation is maintained to prevent the buds from falling off. In the cold spring, measures should be taken to prevent the cold wind from blowing, otherwise the development of buds will be interrupted. At this time, the soil should be kept in an acidic state to prevent physiological yellowing and bud shedding. Plastic decoration. Gardenia likes plenty of sunshine, especially in spring and autumn, which requires more than 8 hours of sunshine every day. However, strong light is forbidden at noon in summer, and it is best to put the flowerpot in a place with astigmatism (light transmittance of 40%-50%). Gardenia has a strong germination ability. When shaping, 3-5 main branches can be left, and all sprouted lateral branches are cut off at the base of the main branch 20 cm, so that the lateral branches germinate from the middle of the main branch, and the roots sprouted from tillers can be cut off at any time. Starting from mid-June, cut the flowering branches in time, and then cut the flowering branches after keeping the base for 2-3 days to promote the lateral buds at the base to sprout new branches.
