How to make the little hibiscus bloom more
Known as the "flowering machine", the little hibiscus is deeply loved by gardening enthusiasts for its fresh and elegant flower appearance. In order to achieve the continuous blooming of hibiscus hibiscus, it is necessary to master systematic maintenance methods such as light regulation, water and fertilizer management, and pruning techniques. Especially special care during the flowering period is the key to determining the amount of flowers. Three elements for cultivating small hibiscus blooms 1. All-day light management Small hibiscus is a typical positive plant. Direct light for 6 hours per day can increase the flowering yield by 40%. Full sunshine should be maintained in spring and autumn, and 30% shade should be covered at noon in summer to prevent petals from burning. In winter, indoor maintenance is recommended to place it on the south-facing window sill, and use it with a fill light to extend the light for 2 hours per day to promote flower bud differentiation. 2. The precise fertilization plan alternately uses nitrogen, phosphorus and potassium balanced fertilizers (20-20-20) and potassium dihydrogen phosphate (1:1000) every 10 days during the growth period, and applies special slow-release fertilizers for flowers during the bud stage. Special attention should be paid to adding bone meal (50g/pot) in late March can promote the development of flower buds, but it is necessary to avoid fertilizer solution contacting the root system and causing seedling burning. 3. Scientific pruning system Carry out retraction pruning immediately after flowering, retaining 2/3 of the length of the branch. Cut dense branches and cross branches regularly every month to keep the crown transparent. Heavy cutting in winter retains 15cm of the trunk, and combined with applying healing agents to the wound can stimulate explosive growth in spring. Four key points for fine maintenance during flowering period Temperature and humidity control The optimal temperature for flowering period is 18-25℃, and the temperature difference between day and night is controlled within 8℃. The air humidity is maintained at around 60%, which can be achieved by laying wet gravel on trays. When the high temperature exceeds 32℃ in summer, ventilation needs to be strengthened to prevent flower buds from falling off. Water management techniques use the "see dry, see wet" watering method, and water 2cm of topsoil immediately after drying. It is better to replenish water in the early morning during the flowering period to avoid excessive humidity at night due to watering in the evening. The bamboo stick method can be inserted to monitor the humidity of the basin soil to ensure that the root system is in a micro-tidal state. Pest and insect pest prevention Spray imidacloprid in advance to control aphids during the budding period, and use carbendazim every half month for disease prevention. When powdery mildew is discovered, the diseased leaves should be removed immediately and treated with Lunason 2000 times solution. Flowering period extension measures to remove residual flowers in time can save nutrient consumption, and combined with spraying flower vitality once a week can extend the flowering period of a single flower by 3-5 days. Avoid moving the position of the flower pot to prevent sudden changes in the environment causing flower drops.
Through systematic maintenance strategies, the little hibiscus can achieve ornamental effects of blooming for more than 200 days a year. The key is to grasp the six-character trick of "bare feet, fat, diligent pruning and skillful" and cooperate with the environmental control of the flowering period to allow this "flowering machine" to continue to bloom and create an amazing balcony flower waterfall landscape.
