Mulch very well (old leaves are excellent) - this keeps the soil moist and friable but also keeps down weeds. Blueberries hate weeds and will sulk or die if one so much as looks at them. Soil should be slightly acid. Avoid lime and shelter from hot winds. Feed with old hen manure or Dynamic Lifter every autumn. I've made blueberries sound as fussy as three year olds, but once you give them what they like, they thrive.
Blueberries can be dried and used instead of currants; just leave them on a rack in the sun for two hot days, and take them in when it's damp. To freeze, wash, drain, and place about a cupful in each freezer bag. Freeze only a small lot at a time so they freeze swiftly; this way they retain their shape when they are thawed.
Figs need full sun and feed well for good crops but most fig trees forgive a little starvation. Mulch well in dry areas or on sandy soils.
Medlars are picked after the first frost, when the leaves have fallen, and the fruit is soft, brown and rotten looking.
The fruit can also be picked at leaf fall and ripened indoors. Eat with vintage port. If you're not a vintage port consumer, scoop out flesh and top with thick cream or yoghurt.
Eat fresh; if by any chance you have a hundred trees and excess fruit, slice it and dry it for winter chook and pig food.
I've seen recipes for persimmon beer, icecream, chutney, jam, sorbet, muffins and sauce. If you happen to like persimmons try standard recipes for any of those, adding persimmon instead of other flavourings. (The persimmon beer was made like ginger beer, but with persimmon instead. It sounded disgusting!)
