Orchids have a definite mystique that not all other flowering plants can offer. They have that special sort of elegance and wonderful appeal about their well-known floral displays. Generally speaking, most orchids can be grown easily with a little understanding of what they require to thrive. If we imitate a orchids natural habitat, you are on the way to keeping them happy for a long time. With regard to the more popular varieties that are easier to care for, once you know how to grow orchids, they can grow bigger and show more flowers to love.
Orchids grow in almost every continent in the world including here in Australia. Our own Queensland floral emblem is the Cooktown Orchid, spectacular mauve coloured flowering spikes last for months. Maintaining orchids is quite simple, here are some basics. These tips can also be useful with other varieties of orchids like the popular Phalaenopsis or moth orchid, which share similar care. As well, the fabulous ground orchidspathoglottis plicata, although this plant can be grown out in our gardens it really has a special place in our homes to enjoy in a pot, to show off to your visitors.
The right amount of light is very important to all of these orchids, commonly shaded windows or well-lit rooms will provide the right amount of light for growth. Your orchid will react to the location you provide by displaying greener leaves if light is too low. Though if too bright than leaves will appear yellow. In the worst case, sunburned leaves show brown spots, if this happens find a less bright location for your orchid. Keep experimenting till you can see their tolerances. Though, too little is normally a common mistake.
Orchids appreciate daytime temperatures of 21’C to 30’c. This range will induce flowering period. Night time temperatures of 6’c to 10’ range are acceptable, but don't let them freeze. If kept warm they will bloom year-round, if the temperatures are comfortable for you an orchid will be the same.
Leave finished flower spikes on the plant well after flowers has finished, this may encourage a second bloom later in the year on the older stems. Or cut 2 to 3 cm off the tip of the stem to a node, ‘scale type leaf look’. Be patient it will be worth the wait.
It’s best to water an orchid as it approaches dryness, usually twice a week in the warmer months. Take your plant to the sink, allow water to run freely through the bottom of the pot, check to see that all parts of the potting mix have been wet. Once a week I dilute an orchid fertilizer and apply to roots for better growth and the plant will bloom more consistently. All three varieties this season are blooming well and are available now in our nursery. Hope that these simple steps can help with your plants and remember once we have great success with growing orchids, they are addictive.
Keep Growing
