When they are actively growing
People also ask
How often do you fertilize orchids?
Orchids will do far better with too little fertilizer than with too much. Many growers recommend the weakly, weekly approach, applying a dilute (1/4 strength) fertilizer each time they water, rather than applying a full dose once a month. Also, it is best not to fertilize a completely dry plant as the fertilizer can burn the dry roots.
How do you take care of an orchid plant?
Water the orchid with the fertilizer like normal watering, taking care not to get any on the leaves. Flush the plant with clean water at least once a month to remove any unused fertilizer.
Do Orchids need potassium fertilizer?
Once the orchid is prepared to bloom, you see flower spikes appearing, return to a balanced fertilizer. Potassium is the third number on the label and is important for developing a strong root system, including the overall well-being of your orchids.
Should you use slow-release fertilizers to grow orchids?
Furthermore, slow-release fertilizers can burn sensitive orchid roots. While some growers successfully use slow-release fertilizers to grow orchids, the odds are greater that you, and me, will have better success with regular applications of fertilizer that give you more control.
