I have discovered scale on my staghorn, what can I do to get rid of it ?

Thank you

Marylin hi;

I would suggest spraying all affected areas with a solution of 1 part dish detergent to 4 parts water.  

The dead scale are not expected to fall off, but after a couple of days you may wipe them off  with a wet rag or even peel them with your fingernail.

This will not prevent future infestations but you would probably not need to repeat for another year or so.

If your problem is not solved,I may be able to recommend some over-the-counter insecticides but these should only be used as a last resort.

Thanks for your question!

I can answer all types of questions regarding ferns: their physiology, life cycle, taxonomy, culture (for both the professional and hobbyist), home and garden application and care, site suitability, and more. I can also answer questions in the fields of greenhouse production, foliage plants, and houseplant care, along with questions in the general field of ornamental horticulture. I may be able to identify fern and foliage plants by photo, but I am unlikely to be able to do it by description (though I will never turn down a challenge). I am not an expert in crop, field, and agronomic production. I am not an expert on annuals, perennials, tree & shrub crops.
