Sunbathing Ramshorn snails?

I don't know why all the ramshorn snails were sitting on top of the water lily leaves but they were, lots of them, looking as though they were basking in the sun. I wouldn't have thought it was something snails do. It wasn't just the ones in the photo - this was a close-up so you could see them clearly. The whole pond was covered in them. Very strange.

They are all the progeny of ten that I paid for in the garden centre years ago, when I bought the plants to stock the pond. Imagine a gardener paying for snails! They've done their job very well though. What with the rampant water lily (triffid) and a few oxygenating weeds, our pond doesn't suffer from that annoying filamental algae or blanket weed that spoils the appearance of so many ponds at this time of year.

We're having a busy week at the allotment. Last night I tucked a bed of straw all round the strawberries to help keep the ripening berries away from slugs and damp earth and then J and I started netting them, but the net has turned into a tangled muddle so we were only able to do a small strip. I need to sort out the netting soon though. We found a big bit and draped it across the jostaberries. I'll shut the fruit cage door soon too. I only close it when the fruit is ripening because the birds do quite a lot of good picking insects off the bushes, so I don't mind them in there most of the year.

There's always such a lot to do in May, planting out, watering, weeding, feeding the growing plants and continuing to sow as much as I can fit in so that we have a succession of harvests. I put in another six runner bean plants today, sown in pots seven weeks after the first batch. the theory is that we have runners over a longer period - however, I've done this before and what actually happens is that they all catch up! A second row of courgettes also went in today. I planted far too many seeds this year and I'm left with more plants than I can use. I'll hang onto them until I'm sure the ones I've planted out are established and then I'll give them away.
Courgettes anyone?

Happy gardening
