Arboricola – Leaking Gum

Anonymous added on January 21, 2014 | Answered

My Arboricola is large and old but over the past year it has been leaking 'gum' from its bottom leaves, which then drops onto the table leaving a very tacky mess. My husband wants me to dispose of it, but I thought you might have and answer before we do.

    That is the number one problem with this plant species. If scale is not the problem, you may have spider mites feeding on the leaf undersides. Look for little webbing on the leaf edges. Mist the foliage with distilled water at least three or four times a week. Treating the plant with neem oil should help as well. If this doesn't stop the sticky dripping, you may need to consider getting rid of it. In the meantime, an old sheet or tablecloth under the leaves to protect your table. For help in dealing with these pests, here are some articles that you may find helpful:,,
