Love orchids? Indeed, there are few things more satisfying for you than seeing them in full bloom indoors.
But if the roots don’t get the proper nourishment, they can lose their charm over time and may even start wilting. In such cases, you must not delay stimulating new root growth. And to help you with that, I’ve put together this guide based on “How to stimulate root growth in orchids.” Come, check it out!
Note that orchids grow in their natural environment by obtaining the required nutrients and moisture solely through their aerial roots. So, maintaining the health of these roots is key to ensuring the orchids are in good shape.
That said, the ideal approach to follow for stimulating root growth will depend on the condition of the roots. And to figure that out, you’ll have to examine the plant first and then proceed accordingly.
A. Examining The Orchids
Remove the orchid from its original potting mix and mist it slightly to see which of the roots are plumping up and changing color. Note that both these signs indicate that the roots are healthy and should be kept intact, while the rest have died out.
Naturally, you should proceed to prune the dead roots and re-pot the plant. But in case the plant is bereft of any healthy roots, you’ll have to condition them to induce root growth, which I’ll discuss later in this guide.
B. Pruning The Plant
Once you’ve identified the dead roots, cut them away using sterilized scissors. You can also separate the dead leaves and spikes of old flowers at this stage. After all, such roots might cause further decay if you let them remain in the plant body.
Now, check for the presence of cut tissues on the root. If you find any, disinfect them using a 3% hydrogen peroxide solution to prevent bacteria from spreading and killing any fungus.
C. Repotting
Since the roots remaining on the plant are healthy and unspotted, they’ll help nourish the orchids by supplying the essential nutrients and hydration. Hence, you can re-pot the orchids after lining the pot with fresh soil.
To promote the growth of new roots in a plant with no visibly healthy roots, you’ll need to recreate its natural habitat, characterized by high humid conditions. Fortunately, there’s an easy technique you can use to create such an environment — by using a plastic bag or Ziploc.
This technique involves placing the pruned orchid in a partially-open plastic bag, followed by adding some well-hydrated sphagnum moss and keeping it in a shaded area. After that, you should monitor the orchid to determine how long it requires to stay in those conditions. And if the plant has a chance at growing new roots, it should happen in a month.
