How often should I water my orchids?
Depending upon the temperature, orchids potted in bark should be watered about once or twice a week. During the summer, the plants may need to be watered every 4 to 5 days. You should follow this rule of thumb for watering : More heat more water, less heat less water.
Plants potted in New Zealand sphagnum moss should be water less often. Water plants once every 7 to 10 days.
Some orchids prefer to be kept on the moist side. This does not mean that the orchid like to be left in standing water. Try to water the plants early in the day, so that the foliage will be dry by nightfall. To prevent bacterial and fungal disease, use Physan 20 once a month.
How often do I need to fertilize my orchids?
Orchids must be fertilized on a regular basis! For best results, use Norman~s Optimal Orchid Nutrients every other week. It is recommended to pre-water plants before applying the diluted nutrient solution if the potting media is dry.
What kind of soil do I need to grow orchids?
None. Orchids do not grow in soil. In the wild, most orchids are found high above the jungle floor, in the tree canopy. For best results, orchids should be grown either in New Zealand sphagnum moss, fine orchid bark mix or medium orchid bark Mix. Orchids must be grown in pots with good drainage. Soil is bad for the plants because it cuts off air circulation at the roots and blocks the drainage of water.
