Unknown Shamrock problem - Knowledgebase Question

Question by mreza

Hi there,
I have a Shamrock plant in my home and recently noticed it is not fresh. As I was checking the leaves I saw some small white creatures on the back of the leaves. I took a couple photos for better understanding.
So, I need some info about this problem and the solution.
Thanks in advance.

It's hard to tell from the photos. Underneath they look like white fly nymphs, but the top side damage looks more like thrips or possibly spider mites.

In any case, I suggest that you fill your sink with soapy water, invert the Oxalis while holding the soil in place, and swirl all the leaves and stems around in the soapy water for a minute or so. You may want to repeat this treatment again in a week.

If that does not work, then consider cutting off all of the leaf stems. As long as the roots are healthy, your Oxalis will produce lots of healthy new growth within a month or so.
