My tunnel is about 8 years old and firm and good but I have awful algy on the outside. I have tried washing up liquid and Domestos bleach but the green algae (and black on the top) remains. Jeyes is not to be used on it (so the tin says) . Can you please suggest something to wash the tunnel with? I use a window cleaning sponge on a long handle as my tunnel is tall and I cannot reach the top by hand

Dear GerryWe have a new property in South-West France (Biarritz) which has two large concrete Jardinieres on the balcony. they have already been lined and filled with compost by the development's landscapers. We expect to spend a week or so every couple of months there. Would you please have any suggestions how we could plant up and maintain these containers in a way that they will survive from visit to visit?
