Planting Site

Where are you planting your tree(s)?

Landscape Ontario Recommended

Hardiness Zone

Your hardiness zone is determined by the coldest temperature your area experiences. Choosing a tree that's suited to your zone means it's more likely to make it through the winter and thrive.

Do you know your hardiness zone?

Soil Quantity

Soil quantity is the amount of soil around your tree that is available forits roots to grow into. Assuming a 1 meter soil depth, how much space is available around your tree?

Sunlight

Different tree types have varying sunlight requirements during the growing season.

Thinking about how much sunlight your planting site receives. Is it:

Height

Clear

How tall do you envision your tree once its fully grown?

Remember, how close your tree is planted to other objects will affect its height. Here's a guide:

Taller trees (over 8 meters) should be planted at least 8 meters away from powerlines.

Medium-height trees (between 6 to 8 meters) should be planted 3 meters away.

Smaller trees (under 3 meters) can be planted safely under powerlines.

Clear

Canopy

The tree canopy is like a leafy umbrella formed by the branches and leaves at the top of a tree. It's the upper layer of branches and foliage that creates shade and shelters everything beneath it. Think of it as the "roof" of the tree.

How wide do you want the canopy of your has fully grown?

Drainage

One way to tell how much drainage a site has is to see whether water pools after a heavy rain.

Does water tend to pool at your site after a heavy rain?

Still not sure?

If it hasn’t rained recently in your area, you can determine the drainage of your site yourself:

1. Dig a hole 30cm wide and 30cm deep.

2. Fill the hole completely with water and let it drain completely.

3. Fill the hole again and measure the water depth every 2 hours. A medium-draining soil will drop at least 5cm every 2 hours, any slower and you have a poor draining soil, any faster and you have a high draining soil.

Salt Tolerance

Will this tree be planted close (less than 5 meters) to a road/sidewalk that is salted in the winter?

Growth Rate

Clear

Trees grow at different speeds, some trees grow quickly, while others grow more slowly.

How fast do you want your tree to grow?

Native Species

A native species is a type of plant that naturally occurs in a specific region and has adapted to the local climate, soil and other factors. Depending on the availability of native species, it may be more feasible to choose non-native species that serve a similar function to native ones, for example by providing a habitat for local wildlife or preventing erosion.

I am looking for a species:

Deciduous or Evergreen

There are two main types of trees: Evergreen and Deciduous. Evergreen trees have leaves year round. Pine trees are an example of evergreen trees. Deciduous trees lose their leaves in the fall. Maple trees are an example of deciduous trees.

Do you want your tree to have leaves year-round?

Watering

Will the tree be watered regularly after planting (at least once per week for the first year)?

Soil Quality

Soil quality testing is useful for understanding the growing conditions at your site and selecting a tree that’s likely to do well there.

Have you had your soil quality tested?

European Beech
Fagus sylvatica
Fagus sylvatica, or European beech, is a non-native tree that thrives in alkaline pH soils compared to its native counterpart the American beech. It is native to large parts of Europe. Although tolerant to alkaline pH soil, it struggles in wet, compacted soils and urban environments with heavy foot traffic. It�s best suited for large spaces like parks or open fields, and are generally considered resistant to deer and rabbits. Beech nuts are toxic if consumed raw or unripe, but otherwise are edible. This tree requires continual watering during dry periods and benefits from mulch to retain moisture. This species is very common in the nursery and has high availability.

Washington Hawthorn
Crataegus phaenopyrum
Crataegus phaenopyrum or Washington hawthorn, is non-native to Ontario with a range that encompasses the eastern half of the United States, from southeastern Pennsylvania and New Jersey to Florida, and westward to southeastern Missouri. It thrives in well-drained soils, adapts to various pH levels, and tolerates urban pollution. While it supports pollinators with its spring blooms, its thorns make it unsuitable for recreational areas. This hawthorn drops small red fruits in fall and sheds leaves in autumn, creating moderate levels of litter. Transplanting is easiest in spring.

American Beech
Fagus grandifolia
Fagus grandifolia, or American beech, is an native tree to Ontario, with a range spanning the east coast of US and Canada that provides vital wildlife habitat and food source. It prefers moist, well-drained, acidic soil and doesn�t tolerate wet or compacted soil. Known for its long lifespan, 200 to 300 years, it produces edible triangular nuts in spiny bracts, ripening in the fall. While American beech is a great addition to woodlands and naturalized areas, it requires careful consideration due to its shallow root system, which makes it susceptible to drought, wet sites, and salt. This species can consume vast quantities of water and with its surface roots may reduce water availability for surrounding plants and garden areas. Beech trees can be moderately messy in autumn due to falling seed husks and leaves, but their ecological benefits make them a wonderful addition to your landscape.

Russian Olive - NOT RECOMMENDED TO PLANT
Elaeagnus angustifolia
Elaeagnus angustifolia, or Russian olive, is not recommended for planting, due to invasive tendencies. This species is non-native to Ontario with a natural range in Asia and limited areas of eastern Europe. It can thrive under a wide range of soil textures including sand and heavy clay, and can withstand flooding and silting, however, it grows best in deep sandy or loamy soils with only slight salt and alkali content. The tree has an aggressive root system and fast growth rate, and it spreads via birds which allows it to outcompete native species. The Auditor General of Ontario has specifically flagged this tree species as a concern in the nursery trades ("Value-for-Money Audit � Management of Invasive Species," 2022), and as such should not be recommended for planting. For an alternative native to North America, consider Amelanchier spp.

One-Seeded Hawthorn, Common Hawthorn - NOT RECOMMENDED TO PLANT
Crataegus monogyna
Crataegus monogyna, or one-seeded hawthorn, is not recommended to plant, due to its invasive tendencies. Native to Europe and Asia, it aggressively spreads by seed, forming dense, thorny thickets in woodlands and fields. It prefers well-drained soils, but is tolerant of a wide variety of soil conditions and nutrition levels, however, it will not tolerate wet or waterlogged soils. While it faces few pests, it is susceptible to fire blight and should be avoided near orchards. Its seeds are dispersed by birds, further contributing to the suppression of native vegetation. This species is expected to continue spreading across North America, and its introduction should be prevented. Additionally, it can be moderately messy with falling fruits, leaves, and spring flowers. Consider planting thornless cockspur hawthorns (Crataegus crus-galli var. inermis) or other Crataegus species as an alternative.

American Smoketree
Cotinus obovatus
Cotinus obovatus, or the American smoketree, is a stunning species that thrives in a variety of soil conditions and is ideal for urban landscapes and woodlots as shrubbery. Native to the southern United States, it is drought and heat tolerant, low-maintenance, and resistant to deer. It grows well in high pH, alkaline soils, and should be located in full sun or partial shade. While its resinous sap has a strong odour, it generally faces minimal insect or disease issues. To maintain optimal health, avoid over-watering, over-fertilizing, and planting in wet, low-lying areas. The smoketree's shallow root system makes it easy to transplant. The American smoketree is native to rocky, usually mountain soils from Kentucky, Tennessee, and northern Alabama west to Oklahoma For a native alternative in Ontario, consider the eastern redbud. Currently not available in the tree nursery, due to its aesthetic beauty and adaptable nature, nurseries are trying to cultivate this species.

Turkish Hazel, Turkish Filbert
Corylus colurna
Corlus colurna, or Turkish hazel, a resilient non-native species from Europe and Asia, thrives in various pH levels and tolerates heat, cold, and drought once established. It faces few pests or diseases, though eastern filbert blight can be a concern. This tree may sucker at the base, requiring regular management. It is ideal for challenging sites, including those with alkaline soil and drought conditions, but has a poor transplant survival rate and is best planted using balled and burlapped or container methods. While it can be moderately messy with fallen nuts, leaves, and catkins, it is well-suited for urban and naturalized landscapes.

American Hazel
Corylus americana
Corylus americana or American hazel is native to Ontario, and ranges from southern Manitoba to southwest Quebec and throughout most of the eastern U.S. It prefers well-drained, moist soils that are high in organic matter, but is tolerant to a wide variety of soil types and pH ranges. It is a versatile plant that can be pruned year-round and tends to sucker from the roots, requiring regular thinning. It produces edible nuts that mature in September to October and attract seed-eating birds. The tree can be moderately messy with fallen nuts, catkins, and leaves, which may require occasional clean-up. Although availability is limited in the tree nursery, this species is becoming more popular and should become more available in the future.

Kousa Dogwood
Cornus kousa
Cornus kousa, or kousa dogwood, a non-native species from Asia, is drought-tolerant, cold-hardy, potentially self-sowing, and disease-resistant. It prefers well-drained soil rich in organic matter with a slightly acidic to neutral pH (5.5-7.0). However, it is still vulnerable to borers and leaf spot, and it doesn�t do well in waterlogged soils due to its shallow root system. It prefers acidic soil and may show chlorosis in high pH soils. Mulching helps keep roots cool, and pruning should be done right after flowering as it blooms on old wood.
