I bought a dwarf bing cherry tree. Why do they say to pull any flowers/cherries for 2 years at the nursery?

Question

I bought 2 earlier this year (Bing and Black Tartarian) and my dog dug up the Bing twice. It died so I bought another today. I am leaving the dead one for now because it took 2 months to die so I want to give it a chance to come back next year although I highly doubt it will. When I picked up the new one at the nursery today they told me to pull off flowers and fruit for 2 years. Why do I do this? Will it produce bad fruit or is it bad for the tree?

Also how often should I water it? When I got the first 2 trees the lady at the nursery said I should try to water it daily but then I was told to leave it and only water it once a week. If that is the case maybe I drowned the first Bing and it wasn't the dog. I watered the old Bing daily after it was dug up.

The Black Tartarian is actually looking just fine and is hasn't been touched by the dog. I did make sure I put a fence around the area where the trees will be so the dog can't get to them anymore.

Answer 1

The fruit and/or blossoms are not bad.

The nursery will tell you this because fruiting trees tend to bloom A LOT even when young.  Young trees can't support the amount of fruit they produce and will sometimes bend and break.  

ALSO, the other poster is correct.  A tree has only so much energy it can produce at one time.  If its in "fruiting" mode, it will not extend its rooting system and not grow thicker, longer branches as it should.  When you prune the blooms/fruit, it keeps the tree out of this production mode and into "growing" mode.  

Watering:  Thoroughly** water your tree directly after transplanting  and the LEAVE IT ALONE.  Water once per week unless it is extremely hot and dry, then only UP TO  times per week.  The #1 reason for new trees dying is over-watering.

Answer 2

they tell you to do that because you want to get the tree established and growing focusing on the leaves and such before you let them fruit because if they fruit they tend to put all their energy into the fruit instead of a health tree. I know when most people buy fruit tree they want the fruit of course but you will be better off waiting.

as for the watering I would water once a day for the first two weeks after you plant them defentaly if it is really hot out with no rain because the replanting stresses them out but of course I would keep an eye out and if they are getting too wet just then cut back to every other day or so. hope this helps
