These catleyas grow on an Australian tree fern tree in front of my home on the Big Island, Hawaii. This year they bloomed with 6 blossoms without ever having been fertilized. So I am beginning to be convinced that orchids do not need all that fertilizer we generally give them in the greenhouse from 1/2 to 1 teaspoon per gallon of water. Maybe that is necessary for commercial growers to get their crops growing faster. Observing them grow on trees for years, my experience has been that they bloom very well without fertilizing them. Of course, if there is heavy rain it can destroy the blossoms. |

Growing cattleyas on an Avocado tree My interest in orchids is more as a photographer than a grower however I do grow a few of my own orchids as an ongoing display out in the back of my house. I prefer to photograph orchids in a rather natural as possible setting hence growing them on trees and not in a greenhouse environment. I have chosen to grow orchids partly because I consider them to be one of the most photogenic of all plants and also here in Hilo,Hawaii they are very easy to grow and require very little maintenance. The featured orchids are growing on an Avocado tree in my back yard. Essentially what I did with them is mounting them on the tree and let them grow freely. Dry spells are rare here in Hilo, Hawaii where the average rainfall is about ten feet a year however they do happen ever so often and then I do water them accordingly. My house sits 280 ft. above sea level. This altitude and the amount of sun, heat , humidity and rain seems to be just about right for all of the Cattleya alliance. |
Chris lives in Tampa, Florida actually outside of the city in the county so the setting is relatively rural. He has no shelter or greenhouse for his orchids. Almost all of them are hanging and swinging in the breeze under a huge 45+ year old oak tree in the back yard. Florida is a good climate for growing so many species of orchid due to the very warm and very humid atmosphere. On average they have one freeze a year always in January. On those nights, he moves all of the orchids and some other plants into protected places such as the tool shed, utility room and/or into his house. Because almost all of his orchids hang suspended from the oak tree, close attention to watering is more important than one may think considering the annual rainfall. They get a lot of rain in Florida since he is in a sub tropical zone however Florida does have its dry months both in summer and winter. Summer dry months are the most critical for watering, making sure the plants do not go into distress due to dehydration. Hanging orchids will dry out faster than orchids on the ground in pots such as the Nuns Orchid. Watering is easy enough, he just turn the garden hose on the plants, watering done. As for feeding orchids, frankly he rarely feeds them . In spite of that they flourish. HIS collection is relatively small comprising Phalaenopsis', Laelia anceps and purparata, Encyclias, Oncidiums, Nunns, Dendrobiums, Cattleyas, Paphiopedilums, Cymbidiums including a cool growing one brought from Oakland, California, one Bulboyphyllum, and one Dgmra.
