I can confidently forecast the complete lack of rain over the next few
weeks. Oh, how so, you ask. Well, I went to the garden centre this
afternoon, and came back with a new water butt, to replace the one that
split in the freezing weather of December. I also bought two new
concrete pots and four new miniature fir trees, to replace the 5 I lost
due to the cold winter and dry spring. Those trees are going to need
watering on a regular basis, so the water in the water butt will
hopefully do that job. Unfortunately, for water to reach the butt,
water needs to run off the four roofs that serve the downpipe on the
back of my house. For water to run off the roof, short of running a
hose from the water mains up there, rain is needed.

I find putting washing on the clothes line often does the trick...
