Thanks.  We had an extraordinarily cool wet spring, so I might gamble on the same cultivar (Puget Gold).  It had the virtue of setting fruit in New England, which I gather most apricots don't.  What would you spray with, and when, to protect against gummosis?

If you peeled the bark off near that gummy spot, you'd likely find the cambium dead all the way   around the trunk.  That kind of gummosis is common in the NW.  It grows during the cool, wet weather of spring, then dries up in the summer.  If can girdle limbs and trunks 3 inches or so in  diameter or less, and makes oozing cankers on larger diameter wood of susceptible trees.  The old treatment was to cut out the canker and paint the wound.  
The disease is most common on apricots, peaches, European plums, and some American and hybrids.  Also on Prunus tomentosa (bush cherry) and P. besseyi, the Sand Cherry of the plains.
You can replant in the same hole.  The disease is spread through the air. Serious spraying and resistant varieties are your best bets.

I planted an apricot tree a few years ago.  It's looked healthy until  
a couple of weeks ago, when quite suddenly the leaves all wilted and  
turned brown.  It is now covered with dead leaves.  (Not dropping  
yellow leaves, as the healthy tree did in the fall.)  Any ideas what  
happened to it?

I saw a little bit of gum on the bark, but nothing that looked  
terrible.  I did not see any other damage. We had a very cool wet  
summer until shortly before it died, when suddenly the weather turned  
hot and dry.  But the apricot started to look dead before the  
raspberries looked even a little wilted.  (They are within a few feet  
of each other, on similar soil.)  It had a decent crop this year, but  
I thinned it pretty heavily, and I don't think the crop should have  
stressed the tree.

I suppose I'll leave it in the ground until next spring - weirder  
miracles have happened than it coming back into leaf.  But it  
certainly looks dead.  I'm debating buying another and replanting in  
the same spot.  Any reason not to?

Thanks.
