Shade cloth is usually supported by a frame to provide shading for orchids from above. It is made in different grades which allows for optimal shading for different orchid species. The presence of trees or buildings on one or more sides of the growing house would dictate that those sides affected may need less shading. With the options provided above for shading, you can prevent your orchids from being destroyed by the sun and rain if you:.
One mistake that beginner orchid growers often make is excessive watering. Beginners can be over enthusiastic in terms of overwatering their plants. For instance, phalaenopsis orchids only require a limited amount of water to survive and grow, and they are more than likely to experience problems such as root rot when overwatered. Humidity is determined by how much moisture is put into the structure versus how quickly it dissipates from it.
It is a consequence of frequency and volume of watering or misting as well as air flow between the inside and outside. Humidity is also the most under estimated variable for a successful culture. The vast majority of orchid species derive from the temperate belt around the equator where humidity is highest.
Species which derive from higher altitudes can be sufficiently tolerant of cold and able to be grown outside their native zone but for best success, humidity of the ambient air needs to be addressed. The ambient conditions such as temperature and dryness of the air outside the growing structure are important.
If the humidity is high and temperatures are dropping, condensation will result. Condensation on flowers may cause damage so it is essential that misting be done early in the day rather than late. Plants such as the Oncidiinae, the Vandaceous group and Paphiopedilums often are cold tolerant but can languish if the humidity is not improved.
Humidity is controlled by air-flow and watering. The simple expedient of blocking off some of the air flow, even if on one side of the growing structure, will instantly result in higher humidity. Ambient humidity is generally below the ideal for orchids in most areas of Australia except for the far North.
The higher humidity of enclosed or partially enclosed structures means there is fewer requirements for watering and that watering or misting results in a more persistent elevation of ambient humidity around the plants. If you are living in an area that has low humidity, providing artificial humidity for your orchid is one of the most important methods to keep them healthy.
Adjusting humidity could be accomplished by misting your plant from time to time, by placing a humidity tray underneath its pot and controlling the air flow into the orchid growing structure.
A balance between light, heat and humidity has to be achieved for optimal culture. When it is imbalanced, the growing environment for orchids needs some improvement. Heat and Humidity : Closing up the growing space restricts airflow and increases humidity and temperature. Humidity can be increased with frequency of watering or misting but unless some containment of the humidity is provided, it is lost quickly if the outside air is hot and dry.
Temperatures can rise quickly in a glasshouse when in full sunlight if no cool air replaces the heated air within. For this reason, most hobby growers ventilate their glasshouses during daylight and close them up at sunset, in all but the coldest climates. Move it outside in the summer, and water copiously. These fast-growing, fanciful flowers appear in every size, shape, and color that you can imagine. It needs filtered light 5 to 8 hours a day.
Feed it well. Cymbidiums are often fragrant, especially those with green flowers. Slipper orchids have long-lasting blooms, flaunting outlandish flowers in sensational and mysterious hues.
They also have a patterned foliage that is attractive even when not in bloom. The flowers are most often white or purple and white. Use a small pot and repot it only every few years. You may occasionally see Phalaenopsis orchids with neon blue or bright orange flowers for sale in stores.
Unfortunately, these flowers have been dyed, which means that the flower will not be the same bright color if the plant blooms again. Many orchids produce babies! See how to pot an orchid keiki. Orchids cleverly produce flowers resembling the pollinator that they want to attract. Ophrys apifera below has the appearance of a female bee visiting a pink flower.
Thus, it attracts the attention of male bees. The bottom leaf of my orchid is turning yellow. What should I do? Let it dry up or remove it from the plant. While it is normal for the oldest leaves of moth orchids Phalaenopsis to turn yellow and dry up as they age, when there is uniform yellowing and shriveling of newer leaves, it is a sign of distress.
The shriveling suggests there is a lack of water reaching the leaves. Check the root system of your plant. If the roots are in poor condition, they cannot take up water. Overwatering can cause roots to rot. Bacterial rot also can occur if water is allowed to sit around the center shoot or in the leaf sheaths for a long period of time.
Water only in the morning so that your plants can dry out by nightfall. Never let them stand in water and keep the plants in a location where they can get good air circulation, indirect light, and a warm daytime temperature above 75F. I am a new orchid grower; I was given a phalaenopsis as a gift and it is so beautiful. I was thrilled to coax more flowers from its buds. I am not clear on what to do when it stops blooming.
Do I trim the whole stem back? Do I leave the stem but just remove any dead flowers? And is any time without flowers a 'dormant' time when I don't want to feed or water it quite as much? Thanks - your information is so helpful! Can an Orchid survive in just a bowl of water and thrive? I have a baby Orchid that has been in water only for a year now.
The roots are exactly was you stated to be considered healthy but will it ever grow any further? I also thank you. I have 4 plants and 2 are just sending out their bloom shoots right now. I can see which are struggling and which need to be repotted, which I haven't done. This is tremendous advice. I have been given an orchid that doesn't look healthy, so it will be a challenge to get it back "on its feet" again. Thanks for all the advice. Thank you! Skip to main content.

By The Editors. Repotting Orchids General Potting Tips Do not repot while a plant is flowering, as the blooms may suffer. Enjoy the flowers, then cut off the spent flower spike with sterile snippers and repot the orchid. Repot at the beginning of the next growth cycle typically in the spring. Orchids should be so snug in their pots that you can pick up the plant by its leaves and not shake out the roots.
How to Repot an Orchid Carefully remove the orchid from its existing pot. New orchids are typically sold in thin plastic containers, which can be cut away. Healthy roots look white or green. Hold the plant upright in the new pot and fill in around it with new potting media, tamping down gently, to about an inch from the top of the pot.
Water the orchid well to settle the media around its roots. Add more media if necessary. Green bamboo and curly willow make for attractive stakes. Orchid Growing Medium Never plant an orchid in standard potting soil. All orchids—especially epiphytic species—need a lot of air around their roots. Mostly, though, it helps anchor plants in pots so they can grow upward. There are specific pots on the market created just for orchids. They're full of holes to expose the roots to more air.
However, no special pot is needed; a terra-cotta or plastic pot will work just fine for most orchids. Choose a pot that's 1 inch at the most 2 inches larger in diameter across the top than your present pot.
The time to transplant orchids is just after they bloom, when new roots have appeared but haven't grown longer than a half-inch, or when the roots start to crawl out of the pot.
Before transferring your orchid, make sure to water it well to help it tolerate any stress from the move. Then follow these steps:. Once your orchid is settled in its new pot, you can keep caring for it like you normally did before. Make sure you have it in a spot that gets bright, indirect light, and water when the potting mix is just about to go dry.
Some orchids can grow for one or two years before they need repotting again, so you can sit back and enjoy its beautiful blooms for a while before needing to repeat this process.
