10 Tips for fertilizing orchids with coffee grounds

Here are the ten best tips for fertilizing orchids with coffee grounds:

1. Mix equal parts of ground coffee and water before adding to the orchid pot.

2. Wait 10 minutes after adding wet ingredients before watering plants; this will help the coffee grounds settle to the bottom of the pot.

3. Pour off any surplus liquid after watering; this will help retain nutrients in the soil.

4. Allow plants to dry out between waterings; this will help reduce fungal problems caused by over-watering.

5. Avoid using too much fertilizer; too much nitrogen can cause leaves to turn yellow, distorted, or die off altogether.

6. Keep an eye on your plants during hot weather; over-fertilization in the summer months can lead to wilting and leaf drops.

7. Fertilize orchids every 3 to 4 months in the Spring and Fall; during the hotter months of the year, bi-monthly fertilization may be necessary.

8. Do not use nitrogen-based fertilizer on plants growing in water; this will cause them to take up too much water and become rootbound.

9. Dispose of coffee grounds properly after using; do not pour them down the drain.

10. Always read product labels before using any fertilizer; you should only use orchid fertilizer under expert supervision.
