Thanks! The four flats of impatiens planted this spring all died! They were infected by fungus and never stood a chance. But the mums are up and running and still in the pots. I'll pull them out later thios autumn and plant some tulip bulbs.
Thanks Spoonman. I am actually replacing my original system which after 26 years has given up the ghost. I could never full power my place as I have too much heavy machinery but with the water wheel to help we do OK!
