Does the gentleman orchid have any skills to change the basin?

Whether it is the seedlings that grow after sowing or those planted by the split method, the pots have to be changed when they grow up to one place. Generally, you have to change the basin for 2 years, and you have to change the basin for 2 years after growing up. This is because:

1. When the plant grows up, the original small pot can no longer meet the needs of further extension of its roots.

two。 It turns out that the nutrients in the potted soil have been almost absorbed, and some new soil with sufficient nutrients should be replaced to supply the need for the plant to continue to grow.

3. Take this opportunity to check to see if there are any infected roots caused by diseases and insect pests, and cut off them in time to avoid spreading the infection; if there are too many fibrous roots, take this opportunity to cut off some of them appropriately.

The time to change the basin is in spring and autumn, and the most suitable time is when the temperature is about 20 ℃. The new basin used to change the basin should be larger than the original basin body, so that the root system of the plant can be further extended, and some perphosphoric acid and soil should be mixed evenly in the culture soil as base fertilizer. When changing the basin, first use a knife to insert the soil along the inner wall of the basin for a week, so that the old basin soil is separated from the basin wall. Then, with the palm of the right hand facing down, put the fork of the middle finger and ring finger into the rhizome of the plant, open five fingers and press the basin soil; turn the basin over with the left hand just to hold the pot soil and flower seedlings on the palm of the hand. Then peel off most of the basin soil. Leave a small part of the root soil, spray with water, and immediately plant in a new pot.

When planting, the plant should be placed in the middle of the basin, so that the root can stretch freely in the basin, and part of the overlong root can be cut off, leaving part of the plate at the bottom of the basin. Then gradually add the soil and shake the basin body while adding, so that the cultivated soil can enrich the gap between the roots and come into full contact with the roots. Finally, raise the plant by 1-2 cm to straighten the root system, shake the basin, gently press the soil surface, pour water once, and place the pot in the shade.
