You introduce a good point, in your post, about "some" foreign plants/trees being invasive, Jack. To be honest, there are many-many plant imported into this country that are invasive. The Asian Lady Beetles are another story too. Still would like to know why one doesn't see June Apple Trees anymore (?)
OK, I'm paying attention now.
I had to do a little research just to feel I had a grip on what it is, a june apple tree. Never heard that terminology before.
homeguides.sfgate.com/carolina-red-june-apple-tree-plants-54756.htmlI have asked around from old people and a few orchard owners about different varieties of apple trees. Mainly because like you "I remember..." and apple trees I see and buy today just don't seem the same any more.
Short answer, they AREN'T THE SAME ANY MORE.
I had a green apple tree at one of my old houses that bore apples it seemed all summer long. It was about half shaded by the house and half shade the rest of the day by the rest of the trees lining the street and then there was the neighbor house 20 feet away from MY HOUSE. Yet that apple tree had great big giant, sweet, bug free awesome green apples it seemed all summer. We never bought apples. We cut and peeled and froze and dried and gave away apples all summer like there was no end to them on top of eating as many as anyone wanted or walked by and wanted.
From ONE TREE.
NEVER trimmed it, sprayed it, fertilize it, nothing. Just pick 'em and eat em.
When I moved the new owner cut that down with in a year.
That's where all your old genetic stock apple trees went. I've bought a dozen different kinds of apple trees since all of them added together don't hold a candle to that ONE APPLE tree.
Go ask an orchard owner. They know the low down but you can plant seeds from an apple you buy at the grocery and that thing will never grow an apple in our lifetime. They are genetic freaks grafted together, cloned and what ever hokey pokey they do to manipulate produce now.
You have to go out specifically looking for the old species trees or find a nursery specializing in it. There are a few. There are a couple trees resistant to cedar rust, I think they produce a green apple if I remember right.
Property today can go through 10 owners over 20 -30 years now adays and all it take is one dumb ass kid who don't want to pick up apples, or cherries, or rake a leaf or "read on the internet these chinese asia grass harp trees are really great..." and the genetics created by surviving in this environment for 10,000 years is ashes out by the curb.
Now everyone who lives in that house from now until for ever is enslaved to Kroger foods to buy apples at 3 dollars a pound. $5 a pound for cherries.... raspberries, grapes... all were right there waiting to be picked on less than a 1/4 acre lot in the middle of downtown Rushville.
Nope, cut that down.
