Lizzie27 If you look on the bag it should have a use by date also don't let it get wet or damp if you do it wont be any good it'll go hard. We have just laid a base for a small shed and used some from early last year it was fine. Hope this is some help.
Lizzie27, It's raining here at the moment otherwise I'd go and look for the name but I think it might be Blue Circle, it a blue and yellow plastic bag. I always leave it in the bag and then put the whole bag in another plastic bag just to ensure it stays dry even in a garage. The concrete shouldn't take to long to get a skin on it if it's not raining but if it should rain cover it with plastic. Where laying a 7 ft x 11 ft base for the green house but have already laid a base for the small shed as I said before. I've laid paths and built walls and covered then due to rain and they were fine. Good luck hard work mixing cement.
Went to lidl and got a good plastic raised bed and a parasol. Sorted out a few plants in the garden but very wet here. Rain has made things grow like mad.
@GWRS , just in case Hazel's not around, Snow in Summer is a name for Cerastium tomentosum, a low growing summer flowering plant with white flowers, hence the name.
@Hazel-1 I Don't know where you are, but ther are 23 suppliers listed on the RHS plant finder list. 16 of those do mail order if you get desperate. It's one of those things you look for while out and about expecting it to be easy to find. I have not seen it for a long time but a big supermarket had a few in a mixed alpine tray last year.
I decided the half dozen Cotoneaster "seedlings" I have kept for years in case I needed them, should go. Some in quite big pots and they are like C. watereri X that grow huge and put on long shoots every year. We have some smaller less vigorous ones that are more suitable and have berries for the birds.
All removed from pots and chopped small to go in the compost heap.
This morning we dodged the showers to do the usual opening GH, feeding birds/tortoises and then once the rain had passed we decided to pick a bowl full of strawberries for our regular customers with some left over for us of course. This afternoon I planted out an edelweiss which was in flower. There will be more to do this evening if the rain holds off, but one thing we won't have to do is watering.
