I have a pear(var. Comice) tree in my garden that was here when i got here so i can’t give any planting advice, but can very much recommend having one. I did end up cutting the top to restrict its height, probably a bit later than would have been preferable, but most of the fruit can be picked from a step ladder.
Some years it is massively productive, last year i had more fruit than i knew what to do with, this year i had i think five fruits off of it – mad really. Some trees, and i think Pear trees are particularly so, will take a number of years before they start to produce in a prodigious manner so it’s worth doing a bit of homework.
One thing i would definitely recommend, if you don’t already possess, is some cane fruit. I have just one blackberry(var. Loch Ness) cane that i did plant that has been incredibly generous every year for the last decade. Zero maintenance beyond generous watering whilst it fruits, it delivers staggered waves of wonderful berries so you end up with a constant ready supply rather than a glut. I keep meaning to put another one next to it because it is by far the best thing i have ever done to my garden.
My Mum has about five raspberry(var. ?) canes that give and give, but they do tend to come almost all together so she freezes most of them.
