White Pine Tree Information – Learn How To Plant A White Pine Tree


By: Teo Spengler

It’s easy to identify a white pine (Pinus strobus), but don’t look for white needles. You’ll be able to pick out these native trees because their bluish-green needles are attached to the branches in bundles of five. Gardeners living in USDA zones 5 through 7 are planting white pines as ornamental trees. Read on to learn how to plant a white pine tree.

White Pine Tree Information

White pines are lovely evergreens with graceful habits. The lush, 3- to 5-inch (7.5-12.5 cm.) needles make the tree look soft and attractive. White pine makes a fine specimen tree, but can also serve as a background plant, given its evergreen foliage.

These trees grow in a pyramidal Christmas tree shape, with the tiered branches emerging at right angles from the central trunk.

How to Plant a White Pine Tree

Before you start planting white pines in the backyard, make sure you can offer the optimal growing conditions for this pine tree. The trees will not thrive in a poor location.

You will need to give your white pines rich, moist, well-drained soil that is slightly acidic. Ideally, the site you choose for white pines should get full sun, but the species tolerates some shade. If you plant in an appropriate site, white pine tree care is not difficult.

The size of the tree is an important piece of white pine tree information. Gardeners with small backyards should avoid planting white pines. The tree can grow to 80 feet (24 m.) tall with a 40 foot (12 m.) spread. Occasionally, white pines grow to 150 feet (45.5 m.) or more.

If the sheer size of white pine trees is a problem, consider one of the smaller cultivars available in commerce. Both ‘Compacta’ and ‘Nana’ offer much smaller trees than the species tree.

Care of White Pine Trees

White pine tree care includes protecting the tree from conditions that will damage it. The species can be injured by road salt, winter wind, air pollution, and ice and snow. It is very susceptible to white pine blister rust, a disease that can kill the tree.

Both gooseberry and wild currant bushes harbor rust. If you are planting white pines, eradicate these shrubs from the planting area.

Eastern White Pine Plant Profile

The Spruce / Adrienne Legault

While the West Coast has taller trees, the eastern white pine is the biggest conifer native to eastern North America. This fast-growing evergreen with long, soft, blue-green needles is commonly found as far north as Newfoundland and as far south as northern Georgia, a span covering growing zones 3 to 8. This behemoth can grow to be as tall as 80 feet and as wide as 40 feet. Eastern white pine is the only pine tree in the East that bears five needles to a bundle. These bundles form clusters that look like little brushes.

Like other pines, this is a gymnosperm—a tree that bears seeds that are exposed in a cone structure rather than enclosed in a nut The tree's cones are cylindrical and are the largest pine cones found in many areas of the tree's range, reaching as much as 6 inches long. By comparison, the pine cones of a pitch pine (​Pinus rigida) measure only about 3 1/2 inches long.

Things to Consider Before Planting Anything Under Your Pine

Firstly, contrary to the general belief, fresh pine needles do not drastically change the acidity of the ground. As the falling needles are only slightly acidic, possessing a pH of 3.2 to 3.8, they change the soil, pH only slightly, without proving to be harmful to any surrounding plants. So, it is better to test the soil acidity levels first. Then you may need to consider the following:

  • Adding limestone powder to the soil if you still believe the soil is too acidic for other plants. Apply at a ratio of 25lbs of lime per 1,000 sq ft area, starting about a year before you plant anything in the area.
  • Digging out the acidic soil replacing it with clean surface soil. Make sure not to damage the roots of the pine in any way.

As pine’s thick foliage covers the entire area below, it is often quite shaded and damp under pines. Cutting the lower branches of the pine tree allows sunlight to filter down to the adjacent soil, making it more suitable for plant growth. Once you do start growing other plants, it helps them to get enough light.

Being evergreen, pine trees absorb a lot of water. It can pose a problem for plants, ferns, and grasses growing beneath, as there is often not enough water left for them to absorb and sustain themselves. Here’s what may be done:

  • Provide extra water for the surrounding plants growing in the same soil for at least the initial years. Once established, they will be able to survive on less water, provided you choose the right plants.
  • Remove any dried up branches, pebbles, and weeds to help the adjoining plants to get their essential moisture from the soil.
  • Prune the pine tree regularly so rainwater may reach down to the very base. It will allow the neighboring plants to take in the excess moisture.

Always keep an eye out for any sign of distress on the plants, even after they get well-established. You may also choose to grow some container plants under the pine tree, so it becomes relatively more comfortable for you to take proper care of them while maintaining an aesthetic landscape instead of leaving the area bare.


Potential Threats

Most white pines don’t perform well in soils that are too wet. In addition to dry soils, they prefer more acidic soils, so a thick bed of pine needle mulch over the root zone will both cool the soil and lower its pH. One inch of water weekly keeps these trees happy.

Eastern white pines are susceptible to some pests and diseases. Rust and root rot can impact the tree’s appearance and health. Bigger problems include white pine weevils and white pine blister rust. Mitigate these potential threats with an appropriate plant health care program.

Pruning:

The Japanese White Pine root system should be pruned gradually in the course of repotting, to ensure always leaving a strong root system. Branch pruning and wiring should be done in late autumn, and the wire left on the tree for 6-8 months at most. Pinch new shoots in spring to 1/3 of their length. This will result in buds forming in the fall at the sites where the shoots were removed. The reason this might be done is to form very short internodes on the branches.


Types of Pine Trees

1. Jack Pine

Scientific Name: Pinus banksiana

Mature Size: Up to 70 feet tall

USDA Hardiness Zone: 3-8

Light: Full sun

Water: Average moisture needs

Soil: Well-draining

This pine tree, also known as scrub pine and gray pine, is native to North America. It grows naturally across the eastern portion of Canada, as well as some of the eastern United States and is known for being very hardy. It is an evergreen conifer that is typically a small to medium-sized tree, but sometimes takes the form of a shrub in poor growing conditions. The tree has an irregular shape, with a crooked and bent trunk and asymmetrical crown. The foliage of the tree is needle-like and has an evergreen color. Cones are pale brown or gray when mature, with a curved tip. The tree has evolved to become adapted to fires, and its cones will remain closed for many years until they are exposed to extreme heat, such as in a forest fire. The cones will then disperse seed to self-sow on the burnt ground.

This is an easy tree to grow that is tolerant of a wide range of soil types, including clay soil and sandy soil. It can also tolerate dry conditions, though it performs best in well-draining, moderately moist soils.

2. Shore Pine

Scientific Name: Pinus contorta

Mature Size: Up to 160 feet tall

USDA Hardiness Zone: 6-8

Light: Full sun

Water: Average moisture needs

Soil: Well-draining, acidic

Cultivars and Varieties: Pinus contorta ‘Chief Joseph’, Bolander’s Beach Pine-Pinus contorta subsp. Bolanderi, Tamarack Pine-Pinus contorta subsp. Murrayana, Lodgepole Pine-Pinus contorta subsp. latifolia

This pine tree is native to North America, where it commonly grows in dry mountain regions or along the coastline, hence the common name of ‘shore pine.’ This tree is also known as ‘twisted pine,’ owing to its trunk and branches that take an unusual, contorted shape. This is often a result of ocean winds that sculpt the tree in a particular way. The tree’s foliage is needle-like and glossy and can vary in color between varieties, from yellow-green to deep, dark green. The cones of the tree have a copper tint and remain sealed tightly shut until exposed to high temperatures.

This tree is predominantly cultivated for its ornamental beauty, and it is the provincial tree of Alberta in Canada. It is tolerant of salt and high winds and thrives in well-draining soils that are slightly acidic.

3. Whitebark Pine

Scientific Name: Pinus albicaulis

Mature Size: Up to 90 feet tall

USDA Hardiness Zone: 2-8

Light: Full sun

Water: Average moisture needs

Soil: Well-draining, acidic

This tree is native to mountain ranges in the western United States and Canada and is known as the whitebark pine because of its bark that is a gray-white color. This bark is smooth when the tree is young, but it becomes scaly as it matures. The trunk of the tree can be straight, but can also become twisted and misshapen as a result of strong winds and other harsh climate conditions. The foliage of this tree is needle-like, with each needle measuring up to three inches long. They can vary in color from gray-green to yellow-green. The cones of this pine tree are oval and are red or purple. They remain closed for long periods of time and only open to disperse seeds when disturbed by animals. A bird called Clark’s nutcracker routinely breaks open the cones to harvest the seeds, and this is the main way the cones are opened. They also provide an important source of food for mountain wildlife, such as grizzly bears.

This is an especially hardy tree that is known to thrive in harsh climates where few other plant species will survive. It is tolerant of drought, snow, wind, and extreme cold. These trees can become dwarfed in unfavorable conditions, and perform best in well-draining soils that are acidic. This is an endangered species, and efforts are being made to conserve the existing whitebark pine population.

This beautiful annual of the Fabaceae family is the most recognized Texas Native Wildflower.

There are about 120 species of Pines that are native to most of the Northern Hemisphere, ranging from just south of the tundra down into the tropics. They are evergreen conifers of the Gymnosperms that usually are trees, but some are shrubs. There are two major groups of Pines: the Soft (White) Pines that bear soft needles in clusters of 5 and bear cylindrical female cones with papery cone scales, and the Hard (Black) Pines that bear hard to semi-soft needles in clusters of 2 or 3 and bear conical female cones with woody cone scales. One feature that separates Pines from other conifers is that they have a paper sheath that surrounds the base of the needles. Pines bear soft, yellow pollinate (male) cones that expand in the spring and release yellow pollen. The seed (female) cones are the brown papery or woody structures that bear the seed. Both male and female cones are on the same tree or shrub, so they are monoecious. The first fossils of Pine show up during the Cretaceous Era of over 63 million years ago during the time of the Dinosaurs. Many pines are used as a source of "softwood" lumber, and there are a number of pine plantations planted around the world, even in the tropics of the Southern Hemisphere with Caribbean and Monterey Pines. Pine trees make lovely landscape trees and a few shrubs. Pines like other evergreens drop some needles all year long, but especially so in autumn in the temperate regions to prepare for winter. Most pines prefer sandy, acid soils, often poor in nutrients, but can grow well in silt and/or clay soils that are acid, and a few also in slightly alkaline soils as the Black Pine of Europe. There are a few Pines, like Loblolly & Longleaf of the southern US, that can grow in draining or aeriated wet soils though generally Pines like well-drained. A good number of Pines sent out a lot of seed after forest fires to colonize the newly open ground.

We have begun to collect the nuts from our pine tree. We salt and roast them, or we grind them into a seasoning. You can grind them into seasoning either after roasting them, or just grinding them fresh off the tree.
