Orchid Fertiliser Basics: Why Orchids Need Special Attention

Orchids Fertiliser differ from typical houseplants in that they are epiphytes, meaning they often grow on trees and rocks in their natural habitat. This means that in the wild, they get nutrients from decaying organic material rather than from soil. As a result, their roots are more sensitive, and their feeding schedule needs to be adjusted compared to other plants.

Proper fertilisation is key to giving your orchid Fertiliser the nutrients it needs to grow leaves, roots, and flowers. But too much or the wrong type of orchid fertiliser can harm the plant. Let’s dive into the dos and don’ts of orchid fertilising to ensure your plants thrive.

20 Orchid Fertiliser Do’s


1. Do use balanced fertiliser.

A balanced orchid fertiliser with equal amounts of nitrogen (N), phosphorus (P), and potassium (K), such as a 20-20-20 mix, is ideal. This ensures your orchid receives all the necessary nutrients.

2. Do fertilise your orchid during its active growing season.

Orchids typically grow new leaves and roots during spring and summer, which is the best time to fertilize. During this time, they need extra nutrients to support their growth.

3. Do dilute your fertiliser.

Always dilute orchid fertiliser to half or quarter strength to prevent burning the sensitive roots. A common recommendation is to mix 1/4 teaspoon of fertiliser per gallon of water.

4. Do fertilise weekly, weakly.

Follow the “weekly, weakly” rule, which means fertilising once a week with a diluted solution. This prevents overfeeding and keeps the orchid well-nourished.

5. Do flush your orchid’s pot.

Once a month, flush the pot with plain water to prevent salt buildup from fertilisers, which can damage the roots.

6. Do use a slow-release fertiliser for convenience.

Fertilisers with slow release offer a consistent supply of nutrients gradually. If you lack the time to fertilise frequently, they might be a fantastic alternative.

7. Do adjust fertilising during bloom periods.

Orchids fertiliser need less fertiliser while blooming. Reduce the amount and frequency of fertilisation when your orchid is in bloom.

8. Do use fertiliser specifically formulated for orchids.

Orchid fertilisers are designed with the right balance of nutrients for these unique plants. Look for a product labelled as an orchid fertiliser.

9. Do use rainwater or distilled water when fertilising.

Tap water can contain minerals that may build up in the potting medium. Rainwater or distilled water is gentler on your orchid’s roots.

10. Do monitor your orchid’s growth.

Adjust your fertilising routine if your orchid’s growth slows or if leaves begin to yellow. This could be a sign of over-fertilisation or nutrient deficiency.

11. Do fertilise after watering.

Always water your orchid before applying fertiliser to prevent the fertiliser from burning the dry roots.

12. Do consider foliar feeding.

Spraying a diluted Orchids fertiliser solution on the leaves can give your orchid an extra boost. This works especially well if your orchid has aerial roots.

13. Do use organic fertilisers if preferred.

Organic fertilisers such as fish emulsion or compost tea can provide a gentler, more natural nutrient supply for your orchid.

14. Do ensure proper light and temperature conditions when fertilising.

Fertilising will only work well if your orchid fertiliser is getting the right amount of light and is kept in a suitable temperature range.

15. Do fertilise newly repotted orchids sparingly.

Give a newly repotted orchid fertiliser time to adjust before introducing Orchid fertilizer. Wait for new growth to start before fertilising.

16. Do alternate between high-nitrogen and balanced fertilisers.

Use a high-nitrogen orchid fertiliser during the growing season and switch to a balanced one when your orchid fertiliser prepares to bloom.

17. Do apply orchids fertiliser to both the roots and the potting medium.

Orchids Fertiliser absorb nutrients through their roots and medium. Make sure both receive the fertiliser.

18. Do take note of your orchid’s species-specific needs.

Different species of orchids fertilizer, such as Phalaenopsis or Dendrobium, may have slightly different nutrient needs. Research your specific orchid for best results.

19. Do fertilise consistently.

When it comes to caring for orchids Fertiliser , consistency is essential. Maintain a consistent fertilisation plan to ensure the health of your orchid.

20. Do use phosphorus-rich fertiliser before blooming.

Before blooming, a Orchid fertiliser with more phosphorus can promote flower spike formation.

20 Organic Fertiliser Don’ts


1. Don’t overfertilise.

Overfertilising can burn the roots and leave behind harmful salt deposits. Always stick to a diluted solution.

2. Don’t use regular houseplant fertiliser.

Regular fertilisers are too strong for orchids and may cause nutrient imbalances. Whenever possible, choose fertilisers made especially for orchids.

3. Don’t fertilise dry roots.

Applying fertiliser to dry roots can burn them. Always water your orchid first, then apply the fertiliser.

4. Don’t fertilise an orchid that’s not actively growing.

If your orchid is dormant or not showing new growth, it doesn’t need fertiliser.

5. Don’t forget to flush the potting mix.

Without regular flushing, salt buildup from fertilisers can damage the roots.

6. Don’t use too much fertiliser before the blooming period.

Excessive fertilisation before blooming can reduce flower production and focus the orchid’s energy on leaf growth.

7. Don’t ignore the signs of overfertilising.

If your orchid’s leaves turn yellow or its roots appear damaged, it may be a sign of overfertilization. Adjust your routine accordingly.

8. Don’t fertilise immediately after repotting.

Wait for the orchid to stabilise and begin growing again before fertilising.

9. Don’t use hard water with fertiliser.

Hard water can contribute to mineral buildup in the potting medium. Use rainwater or distilled water for better results.

10. Don’t fertilise sick or stressed orchids.

If your orchid is dealing with pests, diseases, or other stress factors, hold off on fertilising until it recovers.

11. Don’t fertilise during the orchid’s rest period.

Many orchids enter a dormant phase after blooming, and they need little to no fertiliser during this time.

12. Don’t forget to adjust fertilisation based on the season.

Fertilise more in spring and summer, and reduce fertilisation in fall and winter when your orchid’s growth slows.

13. Don’t use fertiliser on orchids with damaged roots.

If your orchid’s roots are damaged, they won’t be able to absorb nutrients properly. Focus on root health before fertilising.

14. Don’t let fertiliser touch the leaves or flowers.

If fertiliser gets on the leaves or flowers, it can cause burning. Wipe any spills immediately.

15. Don’t use leftover fertiliser solutions.

Freshly mixed solutions work best. Leftover fertilisers can lose potency or cause salt buildup.

16. Don’t store fertiliser in extreme temperatures.

Store your orchid fertiliser in a cool, dry place to preserve its effectiveness.

17. Don’t apply fertiliser directly to the roots.

Instead of pouring the solution straight onto the orchid’s roots, pour it into the potting material.

18. Don’t use urea-based fertilisers too often.

While nitrogen is essential, urea-based fertilisers can accumulate salts and harm your orchid if used too frequently.

19. Don’t rely on just fertiliser for healthy blooms.

Light, humidity, and watering play an equally important role in your orchid’s overall health.

20. Don’t fertilise orchids exposed to extreme heat or cold.

If your orchid is stressed by temperature extremes, wait until it stabilises before applying fertiliser.
