Fruit tree advice please

[purplekat]

Don't think my trees are going to fruit for a few years yet - I did them on a grafting course last year so they're only a year old.
After looking at your list I don't think they should be too prone to maggots

Pitmaston pineapple - small fruited, russetted and fairly late ripening

and two old yorkshire varieties
New Bess Pool red fruit but quite late ripening
Green Balsam green/flushed fruit, late ripening - can't find out much about this one, seen it described as a cooker and a dessert. I think I may have picked it because because it got described as similar to a granny smith for northern areas

I just picked those because they had good descriptions - I never thought about pollination but the gardens over the back have quite a few apple trees so I'm hoping I should be ok.

Your varieties don't sound like they're the typical maggot-magnet. You're probably less prone to maggots up North anyway, due to cooler and shorter summers than we get down South.
With three varieties and others in nearby gardens, I don't think that you'll have any problem with pollination either. Even two varieties that are supposed to flower together don't always manage it in every season, due to each variety having a slightly different response to each growing season and winter.
For example: normally, James Grieve is by far my first variety to flower, but this year (probably due to a cold, Scottish-like winter similar to its native environment), it will be somewhere in the middle-flowering group. My D'Arcy Spice are also later than their usual flowering companions this year.

You can try codling moth traps.
You can try planting a maggot-attracting apple as a decoy to protect your other varieties (that's what I do; I have Ellison's Orange and Scrumptious to draw attacks away from my other trees and it works well).
You can also try home-made traps, using sugared water with some crushed apple and a dash of cider. Put a little into an old plastic bottle, make a few holes in the bottle and see if the moths get trapped like a wasp in a jam jar of water.
You can also grow varieties that are less prone to pest problems.

I recommend cutting open all home grown apples, just to be safe.

You will also find occasional maggoty apples from the shops.

Hi Lavender i would suggest to check Blooming Direct they have gorgeous fruit trees, Last year i bought a Cranberry Pilgrim, it didn't cost much, it will be better if you used Blooming Direct voucher code. I hope this helps
