Check percentage hard/soft surface, confined space, conflicts with other trees, overhead wires, underground utilities, drainage, exposure to prevailing winds, etc.
Remember the tree species' particular requirements i.e. light, water, soil type, space requirements, etc.
What is your main objective in planting a tree?
shade
privacy
habitat creation
aesthetics
fruit production
Are you planting for energy conservation?
plant deciduous trees in south and west to provide shade in the summer but allow sunlight to penetrate house in winter (when the leaves drop)
plant coniferous trees in north and north-west to provide winter windbreak
Check for conflicts and plan ahead for long-term tree survival
look for overhead wires, sheds, pools, patios, decks, clothes lines, children's playground equipment, fences, other trees, pet areas, etc.
consult with neighbours that may be affected
encourage collective neighbour interaction i.e. knocking down fences to allow for wildlife passage, air circulation, enhanced views. Barrier plants or fishing line will keep out dogs, etc.
Minimum tree to structure distances
3 m from building foundations
2 m from hard or paved surfaces or buildings without foundations i.e. garages
deciduous trees at least 0.7 m and conifers at least 1.5 m from fences or property lines (underground utilities often run along property lines in the backyard)
* ensure the tree's main leader is not directly under overhead wires
3 m from hydrant, 1.2 m from driveway edge, 4 m from light poles, 1.5 m from hydro boxes, 18 m from stop signs (boulevard)
Minimum tree to tree distances
Large trees (> 13m tall) 8 - 12 m apart (includes tulip tree, red oak, bur oak, ect.)
Medium trees (7 to 13m tall) 5 - 7 m apart (includes basswood, hackberry, ironwood)
Small trees (< 7m tall) 2 - 4 m apart (includes most fruit trees, most conifers, red bud, nannyberry, serviceberry)
