Yes, the pollinators (bees, etc) should be able to do their job if the pollenizer (the other tree) is just 100' away.

might be helpful to know where you are ...

to find out if the crabs and apples actually bloom at the same time ...

and to find out if your particular specimen actually needs a pollinator

i have never planted a second apple ... and i have never had a failure of crop ... but then.. i dont live in the asphalt jungle ...

and finally .... there is a hardcore bunch of fruit experts.. in the fruit forum ... that i have never seen here ... they may know.. offhand.. about your specific tree ... and ask them about their thoughts.. on yoru particular seller.. orders are always cancel-able .... [in other words.. i wouldnt be using arbor day or michigan bulb.. lol]

good luck

ps: i would not expect a bloom nor fruit.. for a year or two.. well the recently transplanted tree gets a root mass down ... so dont worry yourself.. if nothing but leaves happens this year ... its doing its work underground ....

pps: if its ON ORDER .. and not yet sent.. most of us.. if we were really worried about it... would add a second diverse tree to the order ... if you ordered from a fruit seller ... CALL THEM.. and ask what they suggest as a pollinator ... you are already sending them money.. use their experience ...

ppps: see link on how to plant trees ...

Here is a link that might be useful: no winging it ... follow it ...

Here you go:
Apple 'Pixie Crunch' TM aka 'Orange Pippen'

It's a mid-season apple. As you will see it's parents are:
Golden Delicoius (Miseason to late)
Red Rome/Rome Beauty (same, 2 different names) (Late midseason)

You really cannot go wrong with a 'Golden Delicious'. It's my favorite apple.

The webpage says your Pixie Crunch is self-fertile, however, (2) varieties will always provide for more production.

Other Midseason apples are:
'Red Delicious'
'Jonathan'
'McIntosh' ('Red McIntosh')
'Spartan'

All apple trees need a pollinator. Some need a pollenizer, and most will benefit from one even if they are called "self-fertile".

Thanks everyone for your help. I live in the suburbs of Cincinnati (zone 6), and there are plenty of trees around (just not many fruit trees). I just didn't have a sense of pollinator distance. I have room next to where this tree will be planted, but may want to use the space for a different fruit-bearing tree sometime in future, but will consider golden delicious.

Thanks!
