Encyclia culture: Mounting on wood. After a decade and two hurricanes, Encyclia Borincana

Encyclia Borincana

New growths and aerial root skirt

The spot where the orchid was originally attached.  

I like growing Encyclias attached to pieces of wood or to tree fern pieces because the plants can grow in them for a very long time with no need to repot.   This Encyclia Borincana (alata x bractecens) has been in this piece of teak for more than eight years.   The wood is teak, which is a very tough wood and it is still in good shape.  Many other woods would have been turned to slush a long time ago by insects, bacteria and fungi.   I attached this Encyclia to the wood piece some time in 2014 or 2015.   When mounting orchids, it is very, very important to make sure the plant is firmly attached to the mount, if it can wiggle it will die because the roots will never be able to achieve a firm hold.   

                I hung this plant inside an ornamental croton bush whose leaves provided light shade from the sun and a cooler, moister microclimate for the plant.  The bush was about five feet tall, the plant was four feet from the ground.   In September 7 a category 5 hurricane Irma passed very close to the island of Puerto Rico, in September 20 Maria a high end category 4 hurricane did a direct hit on the island of Puerto Rico. 

                The Encyclia, as well as other plants that were in the bush spent the hurricane outside since I was away from my garden and could not move them to a sheltered spot.   The hurricane ripped the leaves of the bush and when the skies cleared after the hurricane all the plants that were in the bush were exposed to full sun.  They burned and died.  Fortuitously, the Encyclia was covered by some fallen brush and survived.   Weeks later, when I finally was able to get back home, I rescued it and moved it to a shade house that had survived the hurricanes (the shade house was designed to do so, I will write about that in another post).

                The Encyclia has been slowly recuperating and growing larger after the damage it suffered in the hurricane.  It has developed a skirt of aerial roots.    Most of the year I don’t fertilize this plant.   Local rainfall is enough to cover its needs outside its growing season.  When it is growing I fertilize it weekly and water it several times a week, always making sure that the mount is dry before watering it again.

                As you can see in the photo, the pseudobulbs that were in the original attachment site have long ago decayed completely, but there is still an untidy mass of the remains of its dead roots.   I don’t remove them as they retain water and that makes the mount dry slower, allowing more time for the living roots to absorb the water.  I expect in the future that this plant will grow even larger and will start producing branching inflorescences.
