Orchard apricot trees in Spring 2015

I've planted three apricot trees in the orchard, a Royal Rosa, a Moorpark and a Cluthagold.

The Royal Rosal flowered first, at the same time as the older apricot tree.  Unfortunately, while I covered it along with the later flowering trees with frost cloth, a heavy frost occurred on a night when no-one was here to cover it and none of the flowers survived.  Last year one apricot ripened on this tree.

The Moorpark is the next oldest orchard planting.  Flowering later than the Royal Rosa the nightly coverings of frost cloth started in time, and it has the most young green apricots on it.

Lastly, is the Cluthagold tree which was planted within the last year.  It also has a decent number of young green apricots on it, considering.

All the grass has been cleared from around the apricot trees and a layer of mulch put down.  People say (like robots) that the reason for any problem is the grass is not having been cleared from around the trees, but lets look at the facts.

1. If the grass is cleared from around the trees, the lack of rain dries out the soil and cracks the ground.
2. When the long grass is cleared from around the trees, the trunk is often wet despite lack of watering or rain.  Likely from the dew.

To me, the belief that the grass is bad seems to be a religious one.  I think it does more help than harm.  I'd put a photo of some of the cracked ground here, but it just rained this morning for the first time in ages and it won't look as convincing as it would if I had taken a picture yesterday or a day from now.
