Using the WaterWick Water Wick Step 1: Fill the reservoir with water, making sure the water is not too high and does not touch the orchid's roots. Step 2: Push the watering wick(s) into the bottom of the orchid's plastic growing pot until the wick is completely gone. Step 3: Place the wicks securely in the water reservoir, allowing the orchid to absorb water itself when thirsty and dry. Step 4: Check weekly if there is still enough water in the water tank. Step 5: Fill the bowl or pot with water approximately every fortnight. Tip: When watering, check if the orchid needs water. If the orchid is dry, it needs water. If the roots are green, you can wait a little longer before watering.
