Exactly this statement is incorrect (in the context of the small yard with neighbours that spread chemicals around).Crocodile wrote:(чего им там отнимать..ствол один, а под кроной можно бегать).
You can NOT play baseball or soccer or croquet or run through the sprinkles or sled downhill or..... (etc, etc, etc) when you already have apple-trees growing in the middle of your yard (you don't want them right next to the chemical lawn next door). In fact, please visit a fruit farm and see how *low* the branches on the dwarf apple trees should really hang. All you can do around dwarf trees is play hide-and-seek maybe. And NON-dwarf varieties are not good for the back yard anyway. Too big.
This is to make a point that a green lawn and back-yard orchard are NOT the same in usage.
If you are to choose a variety patch (tomato/carrot/raspberry/etc) vs. 2-3 apple/pear trees, the patch is much more efficient vs. 2-3 trees on the same exact area. The patch also introduces redundancy (you have pretty good chance of NOT having any apples, but you *always* will have something in your variety patch).
So as I said:
Фруктовых деревьев не держу.
Места мало. Надо где-то и колхозятам бегать.
Только огород и ягодные кусты.
