A Beginners Guide to Tree Planting

Tree sapling planting in well drained fertile soil

Your tree is more likely to die if you don’t consider the factors that affect its development during their planting. Your trees’ health is directly correlated to the time, location, pre-planning, and species that you choose ever before planting.

72tree.com assembled the following guide with professional tips to help you properly plant and care for your tree.

Best Time to Plant Trees

There is much debate as to when the best tree planting time is. For more moderate climates such as the south, southeast, or southwest, either early fall or early spring are appropriate planting times.

For locations where there is winter snow cover or ground freeze, spring (after the ground thaws) is the best time to plant.

Tree Location

Now that you’ve decided to plant a tree and identified the best time, you’ll need to choose a suitable location. In doing so, take the following factors into consideration:

Sunlight – Does the planting location get full sun (all day), partial sun (morning or evening), or full shade (no sun)

Water – Most tree species require well-drained soil. If your chosen location is in a low-lying area or a depression, water may accumulate and stand, leading to root rot and other diseases.

Tip: Verify that your location is well-drained after a rainstorm or run a hose at the site to see how the water accumulates or runs off.

Soil – The soil where you plant your tree should be loose, mixed with organic material, and turned to avoid compaction.

Tip: Many tree species can thrive in a soil pH level between 5 (acidic) and 7(neutral). You can raise the soil pH by adding lime or limestone and reduce the pH by adding aluminum sulfate, sulfur, manure, or compost (pH levels above 7 are alkaline).

Tree planting spacing for growth and health by species

Spacing – When planting multiple trees, they can be spaced apart according to their mature canopy spread. Tree spacings from 20 to 60 feet apart are standard. This spacing allows the open-grown form of the tree canopy to develop naturally.

Conversely, when planted too close together, a tree may fail to reach its mature height and struggle to absorb enough sunlight and nutrients to remain healthy.

Tip: Follow spacing recommendations for your specific tree species.

Wind – The location you’ve selected should be observed over time to determine whether or not your tree will endure constant wind or violent wind gusts.

Tip: Stake young trees until they can support themselves without bending under pressure. Most trees will take one to two years before fully establishing their root systems.

Structures – A tree’s roots spread far from where it is planted. As roots spread, they thicken and may become invasive. When a tree is planted too close to a house, sidewalk, patio, or driveway, those roots can grow underneath the structure and break up or buckle the concrete.

Tip: Plant trees far from structures with concrete foundations or slabs, and install root barriers to protect building foundations, driveways, sidewalks, etc.

Protection – Weather and wildlife can stress or kill your tree as it matures. By planting shrubs near and around your tree, you can naturally lessen the impact of wind. Surrounding structures will also act in this capacity.

Tip: Discourage wildlife from grazing your tree’s foliage or damaging its bark by putting up chicken wire around the tree, using bark wraps, or by using chemical deterrents.

The USDA Plant Hardiness Zone Map defines planting zones from 1a to 13b. The zone in which you plan to plant a tree will determine which species you should select. You can determine your hardiness zone at planthardiness.ars.usda.gov/PHZMWeb/InteractiveMap.aspx

Tree Species

The species of tree you decide to plant can profoundly impact the surrounding landscape in various ways. Verify that the species you intend to plant is appropriate for the location in which you are planting and consider the following:

Deciduous or Evergreen Trees – If you want your tree to maintain a lush green appearance year-round, you are looking for an evergreen species which may include:

• Blue Spruce
• Scots Pine
• Green Giant Arborvitae
• Magnolia
• Holly
• Leyland Cypress

If you want to enjoy fall colors as your tree prepares to go dormant for the winter, you are looking for one of the many deciduous species which may include:

Tree planting quaking aspen species

• Oaks
• Maples
• Birch
• Sweetgum
• Tulip
• Quaking Aspen

Tip: Regarding quaking aspens, the species has an invasive root system and will produce suckers that are clones of the original tree. When planting this species, be sure that it has enough space to grow and spread without obstruction.

Understory or Overstory – An understory tree may be best if your planting location is restricted or you desire a mid-sized tree. The following species are considered understory, and are shade tolerant reaching mature heights of 20 to 40 feet:

• Flowering Dogwood
• Eastern Redbud
• White Fringetree
• Japanese Maple
• Black Aldar

If you are looking for a tree that makes a statement by its size and you have the landscape to accommodate its growth, the following overstory species reach mature heights of 60 to over 100 feet:

Planting white oak tree species

• Southern Magnolia
• Green Ash
• White Oak
• Southern Red Oak

Tip: When planting multiple trees, understory trees can be planted near overstory trees as protection from strong or persistent winds.

Planting Your Tree

When planting a seedling or sapling, the following should be considered in the preparation of the planting location:

Surrounding Soil – Organic material or pH stabilizing material should be mixed into the soil in no less than a 2-foot radius of where the tree will be planted.

Tip: When transplanting a more developed tree, treat the soil in a 3 to 4-foot radius of the planting location.

Dig the Hole – Measure the distance from the bottom of the trunk to the bottom of the roots or root ball; this is how deep your hole must be. The hole must also be wide enough for the entire root ball to fit without being cramped or bent.

Tip: To confirm the accuracy of the depth, allow the tree to rest in the hole paying particular attention to where the roots connect to the tree. Known as the root flare, it should remain just above the ground.

Water in the Hole – Before planting your tree, provide a deep watering for the hole, allowing water to soak deep into the earth below. This moisture will encourage roots to grow deep.

Plant the Tree – Now that your hole is dug, the soil enriched, and the ground watered, place your tree in the hole covering the roots with soil up to the root flare.

Tip: When covering the roots with soil, do not overly compact it. Water the newly planted tree and allow the soil to settle. As the soil settles, add more to the top, keeping the root flare just above ground level.

Watering – Your newly planted tree should receive a deep watering 2 to 3 times per week. Avoid shallow waterings as they encourage roots to grow to the surface.

Tip: Use a slow-release watering system which maintains constant moisture while allowing proper drainage for excess water.

Tree planting deep watering for root development

During rainy seasons, scale back the watering schedule and increase it during periods of drought. Don’t allow the soil to dry out for newly planted trees completely.

Fertilizer – If you have prepared the soil in and around the planting location, no fertilizing should be necessary for the first full year of growth.

Tip: Use organic mulch around the tree. As it decays, mulch releases nutrients into the soil. An added advantage is that mulch helps the soil retain moisture and warmth, both of which are fundamental for healthy root growth.

Tree Planting and Your Landscape

Your tree is likely to struggle and die without considering the factors that influence its growth when it is planted.

In this article, you discovered how to determine the correct tree species for your landscape, how to prepare the planting location, and pro tips to help you avoid common mistakes when planting a tree.

Your lack of knowledge about soil, sun, water, location, and species when planting a tree can result in its declining health and eventual death.

Tree Planting Guide

Tree planting and care by father and son

If you could make a significant contribution to the slowing of climate change and global warming, would you do it? With every tree you plant, you increase breathable air, reduce atmospheric CO2, and help the local ecosystem.

Planting a tree is the beginning of a journey with nature. The better the conditions are when planting a tree, the healthier it will be and faster it will grow.

72tree.com gathered the following hardiness zone, location, soil, watering, pruning, and care information to serve as a guide when planting a tree.

Tree Planting – Hardiness Zone

Tree species across the world have adapted to thrive in their respective environment. In the United States, the USDA has determined 11 hardiness zones by their average annual extreme low temperatures.

Before choosing a species to plant, you must first determine which hardiness zone the planting location is in. The following is the USDA’s Hardiness Zone Map.

2012 USDA hardiness zone map for tree planting

For an interactive version of the map, visit planthardiness.ars.usda.gov/phzmweb/interactivemap.aspx

As an example, the state of Georgia spans through hardiness zones 6b through 8b, making it suitable for maples, oaks, and poplars among others. For these and other shade trees suitable to plant in Alpharetta or Roswell Ga, visit 72tree.com/5-popular-alpharetta-ga-shade-trees/

Once you have determined the hardiness zone of the planting location, it’s time to consider the planting location and select a tree species.

Tree Planting – Location

While trees are impacted largely by climate, conditions within their immediate environment are equally as important. Take the following factors into consideration when choosing which species and where to plant:

Shade Tolerance – Each tree species may react differently to the amount of sunlight it is subjected to daily. Here are the shade tolerance categories:

• Shade Tolerant
• Intermediate Shade Tolerant
• Shade Intolerant

It is important to note that shade intolerant trees like poplars, eucalyptus, aspen, and pecan trees may self-prune (drop entire branches) if subject to partial or full shade environments.

Tree planting in location with full sun exposure

Wind Resistance – High winds and severe weather will test a tree’s foothold and its elasticity. Planting trees around the following wind-blocking features may help them survive the strongest of winds:

• Fences
• Shrubs
• Raised Garden Beds
• Hills
• Sheds
• Buildings

A tree’s resistance to severe weather is also determined by its overall health and seasonal pruning practices. Crown thinning is the perfect example of a pruning technique that allows wind to blow more freely through the crown, significantly reducing the potential for severe damage.

Understory Trees – These trees grow from 20 to 25ft tall and are shade tolerant. These trees are well suited for “plaza” settings or environments in which they are surrounded by buildings and a mostly shaded setting. In a forest, these are the trees that grow between the forest floor and the bottom of the overstory canopy.

Overstory Trees – These trees grow from 40ft and beyond. Overstory trees are shade intolerant and require wide open space to reach their maximum height potential. In a forest, these are the trees that make up the uppermost part of the canopy.

Root Growth – In nearly all tree species, some roots grow deep into the ground to stabilize the tree, and the vast majority of roots spread out around the tree within the top 2 to 3ft of soil in search of water and nutrients.

It is essential that your planting location be far enough away from sidewalks, pathways, driveways, and building foundations to avoid buckling and structural damage.

Tree Planting – Soil

Since soil contains the organic matter and water a tree needs, it is obvious that the growth and health of your new tree depend heavily on the soil it is planted in. The following guidelines will help you prepare the soil for planting:

Soil Type – There are four basic types of soil:

• Sand – Sandy soil has difficulty retaining water and roots are often unable to establish themselves firmly.
• Silt – Silt is a granular quartz or feldspar material sized between sand and clay.
• Clay – Clay soil is the denser of the soil types, has poor drainage, and compacts very easily.
• Loam – Loam is a combination of the other three soil types and is widely considered to be the best soil for planting.

The majority of tree species flourish in well-drained silt or loam soil, while few are adapted to sand or clay soils.

Tree planting soil composition and pH level

Soil pH Level – Neutral soils have a pH level of 6.5 to 7.5, acidic soils have a pH level below 6.5, and basic soils have a pH level higher than 7.5.

Depending on the species of your tree, it may grow better in acidic soil like pine trees, while most hardwoods do better in slightly acidic to neutral soil.

The pH level of the soil can be lowered by mixing in sulfur, and most fertilizers, while lime or organic mulch, can be added to raise the pH level.

When planting a tree, the soil within a 4 to 5ft radius around the trunk should have its pH adjusted to meet the needs of the tree species, and the soil mixed to a loam consistency to offer the best root development environment.

Tree Planting – Watering

For the first few years of growth, newly planted trees (in well-drained soil) require a deep watering every two weeks or so. Deep watering is when you allow a slow but steady stream of water to penetrate 10in or more into the soil.

Tree planting slow watering system for deep and healthy roots

The benefit of deep watering is that roots will grow deeper into the soil, discouraging surface roots. Surface roots are easily damaged, allowing for either infection or infestation which weaken the tree’s health and could lead to its early death.

During rainy seasons, deep waterings should be spread further apart, every 3 to 4 weeks, and during dry seasons or times of drought, weekly deep waterings may be necessary.

Tree Care After Planting

After a full year of growth, it’s time to start applying routine tree care practices. In late fall, you can prune your tree to encourage spring growth, maintain its shape, or remove diseased or damaged limbs. Learn the various tree pruning techniques and their purpose so you avoid making an irreparable mistake.

Fertilizing should only occur between the beginning of spring and the beginning of summer. Fertilizing in mid or late summer will encourage new growth which will not have sufficient time to harden and will likely die in the winter months.

Tree planting granular fertilizer to enrich the soil

Set up an annual inspection with an ISA certified arborist. An arborist can give you valuable insight as to the influence your landscape has on your tree and vice-versa. He or she can also help in the early detection of disease, infestations, and other potential threats to your tree.

Tree Planting for a Better World

You can help slow the effects of climate change and global warming by planting a tree. With a world population of nearly 8 billion people, research shows that the 3 trillion trees currently occupying the planet with us just won’t be enough for human life to flourish in the coming centuries.

In this article, you discovered the USDA’s Hardiness Zone Map, tree planting guidelines for location selection, soil composition, watering frequencies, pruning, and care.

By neglecting the world’s diminishing tree population, we as a people are potentially condemning future generations to an inhospitable planet in which little – if any – life will be able to survive. When you plant and care for a tree, you are truly helping to save the planet and the future of mankind.
