Re-potting Orchids

Re-potting Orchids

Spring is the right time to do your re-potting. Repotting orchids prevent their roots from getting overcrowded so they\'ll continue producing gorgeous blooms for years to come.

When to repot?

-       When the plant and roots are overgrowing the pot.

-       When the potting medium is decomposed, powdery and drains poorly.

-       The ideal time to repot most orchids is when the plant starts new growth, usually right after it finishes flowering.

 

What potting medium?

Choose a potting material which will not decompose quickly. Mixtures of Pine bark and Moss material have great results. This mixture allows two-three years to lapse between re-potting efforts. Coconut Husk or mix of coconut husk and charcoal also works. But coconut husk decomposes quickly, especially at the bottom of the pot, which increases the chances of root rot and fungal/bacterial infections. 

Also, see the benefits of Pine bark over Coconut Husk:

 

 

What pots to use?

When re-potting, use one size larger pot, using a very large pot will slow down the growth and reduce flowering significantly. Repot every two to three years. Orchids like to be a little tight in their pots. Orchids transferred to overly large pots tend to concentrate their energy on root growth and may not show new growth / foliage or  flowering  for several months.  Also, Media in the center of larger pots may remain wet for long periods and become an unhealthy environment for roots. If possible always use new pots, or if you cannot, wash the old one out very thoroughly and rinse with boiling water to kill any pathogens.

 Orchids love to be hung in the greenhouses and windows. Clay pots with slits or extra holes are preferred in humid environments while plastic pots with extra holes are adequate for drier climates.  Plants in clay pots will need more frequent watering as they will dry out a little faster. Some orchids, such as Phalaenopsis, have roots capable of photosynthesis. For these plants, clear pots are preferred as they allow light to get to the roots.

 

How to repot?

Let the potting medium soak in water overnight before re-potting. Soaking with BlackGold and little of HighBloom has given us good results. Use Styrofoam or charcoal at the bottom of the pots for good drainage.When re-potting, avoid planting the growths too deep  in the mix since the “eyes,” from which new growths emerge, will rot easily if covered with mix.

Cut off the old dried roots with sterilized cutting tool. This will help instigate the new root growth.  Keep the repotted plants in slightly shadier and humid place and slowly move to more light as and when they produce new roots.

 The repotted plants should be fertilized once signs of new root growth are visible. HighBloom (High Phosphorus) and BlackGold application help the plants to produce new roots.


Mounting Orchids

You can mount any epiphytic orchid on a wood piece or tree. Use sphagnum moss at the roots for retaining moisture. Since mounted orchids dry up quickly, frequent watering is required for mounted orchids.
