when to unwrap my peach trees?

Hi all
I have a couple of dwarf peach trees, a blueberry and a pieris, all in large pots on my terrace, and all wrapped up in fleece bags (which I made myself - proud!) When can I unwrap them? Both peaches, and the blueberry are showing signs of budding, and the peaches even have flower buds starting! I'm hoping to avoid peach leaf curl, hence the fleece.
What do you reckon, chaps? leave them tucked up a bit longer?

thanks!

 

Peaches, blueberries and pieris are all hardy. The usual reason for fleecing peach trees is to protect the flower buds from frost and wind as they tend to flower early in the year. If you keep the fleece in place you will need to pollinate them by hand as insects will not be able to gain access. One method is to remove the fleece on mild days to allow any insects around to do it for you. I have no idea if the fleece protects against leaf curl but maybe someone else can advise on this.

 

I was advised that keeping the leaves dry reduces the risk of leaf curl, hence them being covered up during the wet weather. As for pollination I was also advised to hand pollinate them with a fine brush for the best results.
Even more confused now!

 

The curly leaf on peaches is a virus. I have found that it appears on young trees, our older one does not get it any more. The two middling ones got it less the past two years. The thing to do is to pick off and/or up any such leaves and remove them from the garden. Do NOT put them on the compost heap! The peaches can still be eaten even when the tree is affected.

 

Is this really Peach leaf curl lynne?
Peaches also get affected by a leaf curling aphid, it makes the leaves roll up, its only when you unroll them that the aphids can be seen on the undersides of the leaf.
True Peach leaf curl is usually easily spotted, as the leaf becomes almost like a succulent leaf, thick and brittle with often pink or white markings.
They do say the fungus is spread by the rain but I wouldn't think fleece would protect it from rain, the whole idea of fleece is that it lets rain through.
Hand pollenation with a small soft brush is a good idea, when the flowers are fully open on warmish sunny days, if we get any.
I think I'd uncover all three and only recover if a hard frost is forecast

 

thankfully neither tree has shown any sign of leaf curl, it was a precautionary measure!
I'll unwrap them tomorrow, and then rush out and cover them up if it gets a bit chilly.
I'm just a big softie at heart!
