When will the dragon fruit be changed?
As a tropical cactus plant, the timing and operating techniques of dragon fruit change directly affect its root development. Mastering the correct pot changing skills can allow the plants to better adapt to the new environment and lay a solid foundation for flowering and fruit. The best time to change pots of dragon fruit The seedling stage is the key stage of pot change. The first pot change is carried out when the plant height reaches 25-30cm. It is recommended to carry out basin replacement operations from September to October, when the average daily temperature is stable between 20-28℃. Special attention should be paid: Changing pots during high temperature periods in summer (>35℃) can easily cause root rot, while low temperature in winter (<10℃) can cause root damage during dormant period. Operation specifications for pot changing of dragon fruit The technical points of root protection adopt the "three knocks and one dump" method: tap the outer wall of the flowerpot three times, tilt it 45° and slowly pour out the plant. Reserve 1/3 of the original soil for root protection, and use a soft brush to clean the hardened soil. If you find damage to the root system, you need to immediately apply plant ash to the wound and avoid the use of irritating chemicals. The substrate configuration standard is used to prepare planting soil (garden soil + coarse river sand + leguminous leaf soil) in a ratio of 4:3:3, and add 100g of sulfur powder per cubic meter to adjust the pH to 6.0-6.5. The new basin needs to be scalded and disinfected with boiling water. It is recommended to use a breathable pottery basin with a diameter of more than 30cm. Slow seedling maintenance management After changing pots, implement the "three-control maintenance method": control water (no watering for 5-7 days), control light (place in a scattered light environment), and control temperature (maintain 18-25℃). On the seventh day, watering the rooting agent solution (diluted 1000 times) was started, and spraying 0.1% potassium dihydrogen phosphate solution on the leaves to enhance stress resistance.
Through scientific pot change, the root growth of dragon fruit can be increased by 40%, and the fruit setting rate can be increased by 25%. It is recommended to replace the pot soil every two years, combined with root trimming (retaining 15cm of main root), which can effectively stimulate the germination of new roots. Regularly check the drainage holes on the bottom of the basin to prevent root rot caused by stagnant water.
