to allow air to circulate (the air factor sounds a bit like voodoo witch-doctor nonsense to me, but who am I to argue with the experts).
I'd guess that it encourages plenty of movement of air for wind-pollinated species, or easily-navigable routes for flying insects for insect-pollinated types...?
Fruit trees are odd beasties - even beyond the male/female trees thing, some need to have other varieties to pollinate them, rather than self-pollinating, so if yours has stopped fruiting, it could in fact just mean that one of your neighbours has chopped down THEIR fruit tree!
I think that only applies to the pear trees, and believe that's why we have two right next to each other.
In fact thinking about it I'm almost 100% sure of that, because although we got a really crappy crop last year, ISTR we did get some fruit from all four trees.
Think you're probably right about insects - also the air thing may have something to do with tree diseases, though again it all sounds a bit voodoo for my liking.
Some of the leaves were sort of curled up, and inside were loads of black flying things, but I think they only become obvious in certain months (only mature into winged mini-daemons in late summer). Probably depends on the bug.
It's worth pruning buddleia back to the stump every year, even if it's not engulfing anything. Otherwise you get this tall bush with all the flowers and butterflies at the top where you can't see them, and a load of messy brown stalks at eye level.
Definitely - just what I was going to say... my green-fingered mum came round last weekend and commanded me to chop my buddleia to my hearts content - BUT NEVER PRUNE TILL THE FROSTS ARE PAST!! (too late....)
Also, is "going biannual" the plant equivalent to "going postal"?
