To the ancient Greeks, orchids were a symbol of beauty, virility, love and wealth. Today, the orchid is still one of the most popular indoor houseplants, even though it has a reputation for being notoriously difficult to take care of. Fertiliser type is an important aspect of orchid care. Orchids flourish when provided with nitrogen, potassium and iron, all of which are available in commercial fertilisers. A less expensive alternative is to create your own fertiliser that will keep your orchid regal and beautiful.
- Skill level:
- Moderately Easy
Things you need
- 5 large eggs
- Plastic bucket
- 1/2 cup apple cider vinegar
- 1 cup whole milk
- 4 cups water
- Large glass jar with lid
Crush the shells of five large eggs, and place them into a plastic bucket. These shells are an excellent source of potassium.
Add 1/2 cup apple cider vinegar and 1 cup whole milk to the bucket as well. This will provide the orchid with nitrogen and iron, both of which it requires.
Pour 4 cups water into the bucket and stir. The water will dilute the other ingredients, making them safer for the orchid.
Allow the fertiliser to remain inside of the bucket for eight hours. Apply 1/8 cup of the solution to each orchid plant.
Place the remaining fertiliser into a large glass jar with a lid, and store it in the refrigerator for up to two weeks. Fertilise your orchids once a week.
Tips and warnings
- Use dirty fish water in place of the milk, if it is available. Used fish water is an excellent source of nitrogen, which orchids require to flourish.
- Water the orchid before feeding it with the fertiliser.
- Reduce the mixture to one egg shell, 1/8 cup apple cider vinegar, 1/4 cup milk and 1 cup of water if you have a only a small number of orchids that require fertilising.
