Trees. Apple, pear, cherry, zone7a I believe, Full sun.
Toronto. I have good topsoil about 24” to 6-12” of a light clay then loose rock and gravel.
Mostly trying to find more information on self pollinating vs pollinator partners.
How much space each tree should have?
A good place to purchase the trees that’s not a big box store.
Thank you for contacting the Toronto Master Gardeners.
