Last year I planted two types of sunflower - traditional yellow sunflower seeds which I picked out of the hamster food and red sunflower seeds which I bought from a seed supplier on ebay. I planted some more of the same this year but I noticed that there were more sunflowers growing in the garden than the ones I planted. The ones which had self-seeded seem to have grown faster than the ones I started off in the propagator.
There were sunflowers sprouting in the courgette tubs and in several of the plant pots where I put tomatoes and peppers. Most of these had to be uprooted but I left some of those in the larger tubs. One of these is pictured above.
While I was in the garden to photograph the sunflower I noticed that the tomato plants were wilting slightly and the compost in the pots was dry. Now I thought this was slightly odd because there was a lot of rain during the day. I even commented to someone in the office that the rain would be good for the tomatoes. I don't think I am growing a special type of waterproof tomato. I expect it might be the tall fence blocking the rain. Something similar happens with the strawberries, which are on a set of metal shelves which means the lower trough gets less rain than the one on top. This means I sometimes have to go out and water them even if it has been raining.
