How to save orchid roots that are completely rotten and how to grow new roots?

Article Catalog

First of all, the rotten parts need to be removed, leaving about 3-5cm of root core, soaked in potassium permanganate solution for about 15 minutes and then dried. Prepare suitable flower pots and planting materials such as soft river sand or sphagnum moss, and sterilize them by scalding them in boiling water. Then plant the sun-dried orchid into a flower pot filled with river sand, cover it with plant material and compact it, and lay a layer of moss on the surface to moisturize it. After planting, do not water the plant, just place it in a cool place and let it resume growth.

1. How to save

1. Remove all the outer skin of the rotten roots of the orchid, leaving a root core of about 3-5cm in length. Then cut the leaves in half, soak the plants in potassium permanganate solution for about 15 minutes, and then place them in a cool and ventilated place to dry for about half a day. If there is sunshine, you can roll the leaves with newspapers, expose the reed heads, and place them on a shelf. It takes about 10 minutes to bask in the sun in summer and 1 hour in winter.

2. Prepare clean soft river sand or sphagnum moss as planting material for planting orchids. It is best to use relatively moist river sand for planting, and it must be disinfected before use. When planting, you need to cover the orchid reed heads with planting material by about 2-3cm.

3. The flowerpot needs to be soaked in boiling water before use. Disinfect it. Then put a layer of leaves or moss on the bottom, which can effectively prevent sand from losing while also moisturizing.

4. Plant the sun-dried orchid into a flower pot filled with river sand, then cover it with plant material and compact it, and spread a layer of moss on the surface to moisturize it. There is no need to water the plant after planting, just place the plant in a cool place and let it resume growth. When new buds appear on the orchid, it means that the plant is alive.

2. How to send new roots

1. Suitable temperature: Suitable temperature allows orchids to quickly grow new roots. If the temperature can be maintained at around 28 degrees, orchids can quickly sprout new roots. In addition, the suitable temperature for the growth of orchids is between 20 and 30 degrees. Within this temperature range, the roots of the plants can also sprout and grow quickly.

2. Appropriate humidity: There needs to be good humidity inside and outside the pot so that the plant can send new roots. It is best to keep the ambient humidity at about 70%, and the pot needs to be kept wet but not dry, so that the orchid's crystal head can grow quickly.
