Operation 'Lemon Plant'

We've got a little lemon plant in our house. Since we bought it last summer it has been 'invaded' by some kind of parasite that attacks the leaves, flowers and the fruits causing them to dry. It makes some white foam-like sticky thing on the leaves and stem. It was sad to watch the beautiful plant die slowly in front of our eyes so I decided to take action this morning. I made a dish of soapy water, put on my gloves and got to work. I wiped clean each and every leaf, flower and branch. I hope, if I repeat this process once or twice, the plant will be saved. Nowadays when you enter our house you get this strong smell of lemon flowers. I intend to keep this smell and won't give in to a little bug! :-)
