When Orchids Blossom, Should They Be Fertilized?

Orchids are plants that thrive in low-nutrient potting media, making them ideal for regular fertilization. However, they are not heavy feeders and thrive on weak solutions applied regularly. Over-fertilizing orchids can lead to dry leaf tips and burned root tips. The growing season is the key period when it is essential to focus on fertilizing orchids. Starting fertilizing in early spring when new growth is noticed is recommended.

During the blooming period, orchids should be fertilized with a balanced fertilizer that provides the necessary nutrients to support flower production. It is best to use a balanced fertilizer that is dilute to half the recommended strength and watch for temperature changes. Orchids require specific nutrients, including nitrogen, phosphorus, potassium, and trace elements, for optimal health. A 20-20-20 NPK blend should be used “weekly, weakly” at a diluted solution.

Fertilizing orchids during their active growth phase is crucial for their proper development and blooming. It is recommended to stop fertilizing when the plant starts its blooming phase. Orchids need to be fertilized when they are in vegetative growth, which is crucial for their proper development and blooming. Watering orchids with pure water before fertilizing them is recommended, but not every fourth watering.

Experts recommend fertilizing Phalaenopsis orchids once every other week or at least once a month after the last bloom has fallen off. Fertilizing orchids while they are resting should be done at least once a month. A complete, inorganic fertilizer is a reliable way to feed orchids, with formulas varying depending on the purpose. As a general rule, fertilize orchids every 2 weeks during peak growth (spring and summer) and once a month during dormancy (fall and winter).
