Q.Wrinkle Leaf
Two years ago I had one peach tree. The leaves started to wrinkle up and fall off, and this was the first year we had fruit on the tree. Then last year the tree seemed to be ok, no fruit because of hard freeze. This year the wrinkle leaf is back and fruit is starting to form, but the condition is worse than the first year. What can I do to get rid of this problem? Will it spread to my nectarine tree?

In peaches, this indicates a nitrogen deficiency. Have the soil tested to better indicate how much of a deficiency and add a nitrogen heavy fertilizer to the soil.
