spider mites on Calathea Corona
Quick answer
If your Calathea Corona has spider mites, the most likely cause is: Spider mites are listed as the most common pest on calathea (prayer plant) foliage, including calathea varieties grown as houseplants; they take hold on the patterned leaves of this tropical, humidity-loving genus that the book explicitly recommends keeping warm and humid.
Start here:
- 1. Wash all the leaves and stems of the calathea corona with a gentle stream of water, then wipe with a mixture of castile soap and water, and finally rinse again with water.
- 2. Make your own insecticidal soap spray by combining 1 Tbsp. (15ml) of castile soap with 3 oz. (1 L) of water; shake well and use immediately, and avoid neem oil because neem oil does not agree with calatheas and will cause the leaves to turn yellow and fall off.
