How to divide an orchid with too many roots, and can the excess roots be cut off?

When a cultivated plant has too many roots, you can cut them off and then divide the plant, replanting it anew. Take the plant out of its original pot, comb out the root system, and cut slowly. After that, wash the plant clean in water, then plant the divisions separately and carry out normal follow-up care. It is best to choose spring and autumn for this.
I. Method
1. When you find the roots have grown long and dense, you can take the plant out of its original pot; do not be too impatient, as it is easy to damage the roots.
2. Prepare the tools you will use next; sharp scissors or a blade will both do.
3. Pick up the plant, comb out the root system, and then look carefully; during this process you need to reduce root breakage.
4. Find a suitable spot and cut slowly. After making one cut, you need to see the plant completely separated before making the second cut, otherwise it is easy to leave the plant broken into pieces. After that, cut off some of the old roots at the sides.
5. Wash the plant clean in water, apply a medicinal powder that promotes recovery, and then plant the divisions separately.
6. After planting, carry out normal care; do not water within 3 days, as this helps healing.
II. Timing
When carrying out these operations, generally choose the spring and autumn period; this time is exactly when the plant is at its most mature, so damage can be reduced. Summer temperatures are very high, and if you choose that season, it is relatively easy to trigger pathogens.
