1、 Rejuvenation method

1. Off pot pruning: if you want the weak seedlings of orchids to grow strong, first take them off the pot and cut off the unnecessary parts with scissors. The so-called unnecessary part is the rotten roots and dead leaves on it. These parts will consume the nutrients in the plant, resulting in its failure to grow smoothly. If the root system is cut more, additional leaves need to be cut to reduce the speed of water evaporation and reduce the burden on the root system. After cutting, put it in a ventilated place and dry the cut

2. After pruning, the weak seedlings need to be planted again. The plant material should contain orchid bacteria, have high permeability and have certain moisturizing ability. This is more conducive to its growth. After planting, it should be placed in a warm position of about 20 ℃ for curing. During the period, keep ventilation, proper shade and suspend fertilization. After a period of time, when its root system is slightly developed, apply fertilizer appropriately

2、 Watering method

During the rejuvenation of orchids, the frequency and amount of watering should be strictly controlled. It's best to water after the plant material is dry. The plant material shall be thoroughly watered every time, but there shall be no ponding in the plant material. When watering, use clean water. It's best to use purified water. If not, you can use tap water that has been dried for 1-2 days
