Gardenia breeding methods and matters needing attention
The white and fragrant gardenia are the main characters in summer courtyards, but many flower lovers often encounter problems such as yellow leaves and no flowering during the maintenance process. If you master the correct maintenance methods, you can make gardenia bloom and fragrant every year. Cultivation substrate preparation techniques for the five core elements of gardenia maintenance Acidic soil is the key to the growth of gardenia. It is recommended to use a mixed substrate of humus soil + peat soil + perlite (3:3:1), and add pine needle soil every quarter to adjust the pH value. It is recommended to replenish ferrous sulfate solution every year to keep the pH between 5.5 and 6.5. Light and temperature control Keep scattered light for 6 hours a day in spring and autumn. Sunshade nets are needed to filter strong light in summer, and full sunshine in winter. The suitable temperature for growth is 18-25℃, and needs to be kept above 10℃ in winter. It is recommended to winter indoors in northern regions. The secret of water management follows the principle of "seeing dry, seeing wet". Pour water thoroughly when 2cm of topsoil is dry. Spray on leaves in the morning and evening in summer, and control water to soil micro-tide in winter. Use rainwater or tap water to rest for 3 days. Scientific fertilization plan Apply diluted soybean cake fertilizer every half a month during the growth period, and use potassium dihydrogen phosphate solution (1:1000) during the budding period. Pay attention to stopping fertilization for one month after flowering and avoid using undecomposed organic fertilizers. Key points for pot change and pruning: Change the pot every two years in the spring, and cooperate with root pruning and disinfection. Cut off cross branches and sick branches in time every day, and prune residual flowers after flowering to retain 2 pairs of leaves. Re-cutting should be completed before early spring sprouts.

The water transplanting method has the highest success rate: select semi-lignified branches, retain 3 leaves, soak in rooting powder, hydroponic, and transplant 2 weeks later. The high-altitude layering method is suitable for shaping old piles, and the girdling area is wrapped with moss to promote rooting. Solutions to common problems Yellow leaf treatment takes three steps: check the humidity of the basin soil → test the soil pH value → observe the light intensity. If you don't bloom, you can replenish bone meal and adjust the placement.
