Last week I sprayed my indoor plants (Clivia, Aloe, Walking stick succulent) with the combination treatment of water, dishwashing liquid and oil in order to get rid of the few aphids I found (brought in by a gift of an African violet).
There has been no trace of aphids since, but the liquid formula is still on the leaves of the Clivia, a very large plant by now. Should I do anything — such as washing the formula off the leaves or leaving the oil and liquid on the plants?
