When does clivia change soil in autumn?
As a popular indoor ornamental plant, the key to the maintenance of Clivia is root management. Regular soil changes every year can not only update soil nutrients, but also prevent yellow leaf problems caused by root aging. Mastering the correct time and method for soil replacement can keep the plant strong vitality and bloom in an elegant flower appearance. The best operation window for soil replacement for Clivia is selected for the best operation window in autumn. When the average daily temperature stabilizes at 18-25℃ from September to October in autumn, Clivia enters an active growth period. At this time, new roots germinate quickly after soil change, which can effectively absorb soil nutrients and store energy for winter. It is necessary to avoid high temperatures in early autumn (>28℃) and low temperatures in late autumn (<15℃) to prevent root dehydration or frostbite. If you miss the autumn soil replacement during the spring alternative operation period, supplementary operations can be carried out from April to May. At this time, special attention should be paid to avoid the plum rainy season. Excessive air humidity may lead to water accumulation in new soil and cause the risk of root rot. It is strictly prohibited to change pots during the high temperature period in summer, and the resistance to stress during the dormant period of plants is significantly reduced. Scientific operation steps for pot replacement root pretreatment skills, stop watering 7 days before soil change to make the pot soil slightly dry, and gently tap the pot wall to assist in removing the pot when inverted. Use disinfectant scissors to trim aging and rotten roots, and retain the strong main root. After pruning roots, place them in a cool place to dry for 2 hours to promote wound healing. The recommended formula for the matrix ratio plan is: 40% legus soil +20% pine needles +15% volcanic rock particles +15% wood chips +10% bone meal. A 3cm ceramsite drainage layer is laid on the bottom layer, a mixed substrate in the middle layer ensures breathability, and the surface layer is covered with fermented pine phosphorus to moisturize. The pH value is preferably controlled at pH 6.0 -6.5. Key points for pot maintenance: Place the plant in the center of the pot and fill the soil to 1 cm above the junction of the roots and roots. Gently lift the plant to stretch the root system and avoid excessive compaction of the soil. After changing the pot, place it in a scattered light environment. After 72 hours, slowly pour root-fixing water along the pot wall, and suspend fertilization within 15 days. After soil change, maintenance management observed the germination of new leaves, and gradually increased the light after about 2 weeks. Maintain the environmental humidity of 60%-70%, and cooperate with the basin method to keep warm in winter. Use bamboo sticks to detect soil hardening every quarter, and carry out surface loosening operations in a timely manner.
By accurately grasping the timing of soil change and standardizing operations, and cooperating with scientific post-maintenance, Clivia can not only safely pass the adaptation period of pot change, but also promote flower bud differentiation and achieve the ornamental effect of reblooming every year. Remember the maintenance formula of "changing soil to protect the foundation in autumn, and scientifically matching soil to promote flower bloom" to let your clivia show its best condition.
