Tips for Easy Orchid Care
Filed Under News And Articles · Tagged:
Orchids truly are a very adaptable to their environment and much easier to grow than their reputation has afforded them. There are certainly easier varieties to grow than others, and you will need to provide the orchid of your choosing with the right conditions of light, temperature, and humidity if you are going to be successful.
Light is the key ingredient to successful orchid growing. The best rule of thumb is to give your orchids as much light as they can tolerate without burning their leaves. It is often difficult to really measure light without a light meter, but on an average light coming through a sunny window can register up to 4 to 5 thousand foot-candles, where the window view on the shaded side of the house would be only 600 fc. or less.
Two varieties that can be grown in lower light, which would be below 1000 fc are Miltonias and Phaleonopsis.
Cymbidium, Dendrobium and Vanda orchids need more medium light which is between 1500 to 3000 fc.
Orchid Light tips
- Watch new plants in the area you bought them for to make sure they are not burning as they adapt to the new environment.
- If you suspect your orchid is getting too much light, touch the leaves and if they feel warmer than the surrounding air, move them to an area with lower light intensity.
- Keep your plants and windows clean, as this gives them more available light.
- Once the orchid blooms, move the plant out of direct light, as the flowers will last longer.
- Turn plant occasionally (but not when they are in bud) to keep them from getting lopsided.
- If you need to move an orchid into brighter light do so on stages over a period of several weeks so the plant can acclimate itself to the stronger light without burning.
Orchids are used to a temperature fluctuation. Cooler temperatures at night allow them to store the sugars made in photosynthesis which is what they need to make flowers.
Most orchids prefer temperature ranges that people prefer, with an average night temperature between 55-65 degrees.
Orchid Temperature Tips
- Place orchids with lower temperature needs closer to the floor and those with higher temperature needs on shelves.
- Don’t let your orchids touch the windows.
- A fan can be used to circulate warm air or bring cool air from another part of the house.
Orchids thrive best in a relative humidity of 40-70 percent. This is not normally the range inside, as humidity refers to the moisture in the air, not in the soil or on the plants. Gentle movement of air can be helpful to your orchids. It cools down the leaves and allows your plants to tolerate higher light intensities with out burning.
Orchid Humidity tips
- Placing orchids on top of an inch or so of gravel with water surrounding them will help with humidity. (Just do not let the plants sit in water). You will want to clean the stones with a mild solution of bleach about every three months, just make sure they are well rinsed before you place them back in the saucer as bleach is toxic to plants.
- Misting can help but do so only when you know the plants can dry off before nightfall. You want to mist around the plants, not directly spray the flowers and leaves.
- Grouping orchids together will create a more humid environment, just makes sure there is still room between them for air to circulate.
- Adjust air vents so air does not blow directly onto plants.
The care of your orchids once you find the environment in your home that best suits the variety you have chosen to grow, is also a key factor in your overall success.
Over-watering the major cause of death to orchids (and most interior plants).
Orchid roots enable them to capture and retain water, but these roots also need air so keeping the orchids too wet, or sitting in water can be very detrimental.
Orchid Watering tips
- It is best to let your orchids reach a point of getting almost dry and then when you do water to water thoroughly, ideally by taking to a sink or bath tub and watering deeply, and then drain but not letting them sit in any water. This will flush out any salts that may have accumulated.
- Use room temperature water if possible as cold water shocks the roots, and preferable water in the earlier part of the day.
- If your water is hard, or has a lot of dissolved minerals, flush with distilled water (or rainwater) every so often to keep the minerals from building up.
- NEVER let your orchids sit in water.
Remember that in the wild orchids receive their nutrients from the decaying organic debris that collects around their roots. They do not get nutrients directly from the organic material but from the bacteria that created through the breakdown. Orchids will grow best if you can mimic this process by fertilizing them frequently but weakly. A good term to remember is fed them weekly but weakly. What type of fertilizer you use depends on the growing medium the orchid is in.
Orchid Fertilizing tips
- Orchids grown in bark need a fertilizer that has more nitrogen because the bark decays so rapidly. A good formula would be 30-10-10, or 15-5-5.
- Plants grown in tree fern fiber do better in a balanced formula like 20-20-20, as this material breaks down slowly and you do not need as much nitrogen.
- Orchids in lava rock do well in a balanced fertilizer as the lava rock does not break down at all, but you need to watch out for an accumulation of salts.
- Do not fertilize your orchid if the plant is dry or under any stress.
- Resist the urge to force your orchids. Adding extra fertilizer actually stunts the growth.
- Fertilize only when the plants are actively growing, and let them rest from the time the new growth has matured until it starts to produce new growth or spikes.
