How to renew and rejuvenate the magnolia

After a long time of cultivation, the growth of the plant gradually slowed down, the pseudophosphate stem elongated and thinned, leaving only a few upper leaves, almost no new roots, and only a few old roots to maintain life and showed an "aging" state. At this time, the method of renewal and rejuvenation should be taken to bring it back to life.

In May of spring or September of autumn, the Magnolia plant was removed from the pot, the root soil was removed, the residual aging leaf base was removed, the pseudo-bulb part was washed and dried, and the lower part of the plant was cut off with a sharp knife at the lower part of the robust leaf base. The incision is required to be smooth and smooth to avoid crushing injury affecting the hair root. Immediately apply charcoal powder or sulfur powder to the incision to prevent bleeding and infection, and then place in a cool and ventilated place. When the surface of the incision is slightly dry, plant it in a new flowerpot with moist sandy soil, pour water once after 2 days, and then restrain water to keep moisture, careful care, and taboo fertilization; under the temperature of 20 ℃ and 25 min, new roots can be seen around the pseudobulb incision in 10 days; the roots can grow to about 5 cm in 30 days; and the root length can be more than 20 cm in 40 times. . at this time, the cultivated soil can be poured into the basin and maintained normally. Like the foot buds of ramets, the growth rate is faster and the growth potential is restored.

Cut off a section of false bulb and old root, as long as it is not rotten, can be buried in plain sand in a cool and ventilated place, proper care, new buds may sprout around the incision, but it will take 2 years to grow.
