Begonia pot changing time
As a perennial woody flower, the root maintenance of crabapple directly affects the flowering quality. The operation of changing pots may seem simple, but in fact it hides tricks. Choosing the wrong time may cause leaves to dry out or even plant death. Mastering the time nodes and countermeasures of the three key stages can allow your crabapple flowers to smoothly pass the adaptation period. The golden rule for changing crabapple pots is to control the season. Before new buds sprout in early spring from March to April, and around the autumnal equinox from September to October. The temperature in these two periods is stable between 15-25 ° C, and the air humidity is maintained at around 60%., is the best window period for root recovery. Changing pots at this time can minimize root damage and avoid the dual risks of excessive transpiration at high temperatures in summer or low temperatures in winter. Before changing pots, the key is to stop watering 3 days in advance to allow the pot soil to slightly damp, and choose a breathable pottery pot with a diameter 5 cm larger than the original pot. The mixed soil is prepared at the ratio of humus soil: perlite: vermiculite =5:3:2 to ensure that the new soil is rich in organic matter and has good drainage. Retaining 1/3 of the original soil for root mulch when changing pots can significantly improve the survival rate. First aid plan for dry leaves. Environmental regulation and control were carried out in three steps. When the leaves were found to be curled and dry, the plants were immediately moved to a scattered light ventilation place, and the temperature was maintained at 18-22℃. Use the dipping basin method to replenish water, control the water level at 1/3 of the height of the basin, soak for 20 minutes and drain. Use a transparent plastic bag to cover the plants, open and ventilate for 2 hours a day to create a small environment with 85% humidity. If root diagnosis and treatment do not improve after 7 days of maintenance, re-inspection is needed. Cut off the black and rotten capillary roots and keep the main root length of 8-10cm. Soak it in potassium permanganate solution (concentration 0.1%) for 30 minutes to sterilize, and replace it with a new disinfection substrate and put it on the basin again. Focus on retaining the top 2-3 healthy leaves to reduce water evaporation pressure. Key points for continuous maintenance Avoid fertilization within 15 days after changing pots. Organic liquid fertilizer diluted 2000 times can be applied after 20 days. Gradually increase the light after the new leaves are unfolded, and adopt the "morning light and afternoon shade" mode, that is, receive 3 hours of direct light in the morning and shade protection at noon. Regularly rotate the flowerpot to ensure uniform light reception and prevent off-crown growth.
By accurately grasping the time window for basin replacement and scientific postoperative maintenance, even if the leaves are dry, they can be effectively saved. It is recommended to take photos of the root state for comparison when changing pots every year and establish exclusive maintenance files. When the plants regain their growth vitality, you can try high-pressure propagation to cultivate new seedlings so that the crabapple flowers can continue to bloom and be beautiful.
