Apricots?

We have an apricot tree we planted about five years ago. It is making slow progress and I think in that time we have had maybe two apricots in total. The problem is that apricots, like many stone fruit trees, flower early in the Spring. This leaves the flowers very vulnerable to frosts and they fail to set fruit. Or when matters look more promising the young fruit drops off. The flowers are, nevertheless, very attractive, enhanced by the reddish glow of the buds and the sepals. 

Our apricot tree is now in flower and this year I am going to see if we can enhance its fruiting prospects by flinging a sheet of horticultural fleece over it when overnight frost is forecast.
