Bedding plants

What with one thing and another we have sadly neglected our garden this spring. Mr H hasn't done his veg patch and I've done nothing about my container garden. Until today.

With our National Care Homes Open Day happening next Friday we have been feverishly planting and hanging so that the Home is abundant with colourful flowers. Mr H picked up a few extra for our own garden today so I duly planted them, this is despite me saying don't buy any as we are going away on Sunday for a week. We'll buy them on our return I said. However younger son has come home while we are away to do some jobs and look after the cat/house so he can water the fragile new plants.

What could possibly go wrong ?
