|Help! My umbrella plant has a sticky substance on the lower leaves and these little brown insects. Can anyone advise on what they are and how best to remove it? It seems happy otherwise so really hoping to save it!

|Your Schefflera has a scale insect infestation. Mix a solution of 5 parts water, 1-part alcohol, and a squirt of liquid dish soap. Then, spray all leaf and stem surfaces until they are dripping wet. It is a very messy task, but unless you get complete coverage and make direct contact even with the ones you cannot see, the survivors will reproduce, and the infestation will return. Be sure the solution runs into the crevices where leaf stems attach to the main stems.
