Trees & Landscaping

I'm a big fan of edible landscaping so I set out picking out fruit trees for my yard. My mom and I both like saving seeds from fruits from the grocery and seeing if we can get them to germinate. She gave me a Meyer lemon tree she had bought as a house (yard?) warming present and a nectarine tree, both of which landed in the front yard. She also gave 3 young  pomegranate bushes she had started from seed. I added an olive tree and pear tree and 2 kiwi bushes, all bought during late season 50% markdown from Wally World. I've raised many a tree from avocado seed but heard recently that trees from seed don't bear fruit, only them from grafted. Until I hear different I won't bother w/ avocado trees as a food source.
My house faces east and the southeast side of the yard is rather a bowl which quickly becomes a swamp after even a light rain. Any time I see a sack of leaves or grass clippings on the roadside I fetch them home to try to mulch, compost and fill this sucker up. A couple of months ago I heard a racket on the next street over and saw a tree cut down and the stump being ground. I went and talked to the fella in charge and got a pickup bed full of pine stump grindings free of charge. As I dig around the yard I find rocks, bricks, stumps, etc. all of which go into the swamp.
The back yard already had a mulberry and 2 catalpa trees and I have added  kumquat, lime and satsuma trees close to one corner and fig tree and 2 blueberry bushes towards another. Muscadine vines creep over the new 6' cypress privacy fence. A boardwalk made of some 90% salvaged wood leads from the deck to the 12' x 14' storage building w/ an arbor of new muscadine vines on it.
When moving in I found a couple of bird feeders, filled them up but didn't get many visitors. I actually got more corn and sunflower plants from seed being kicked out than birds at the feeders. I'm letting the stuff grow as hopeful free food for my quack pack, 3 geese and 8 ducks I bought as 1 day old hatchlings. The original plan was for me to eat them but after raising them up from wee bairns I can't see that happening unless the choice is eat them or my 2 dogs. Vlad is a Jack Russell and Bella is a Dachshund, both near 7 years old.
