Escape of the invasives: Top six invasive plant species in the United States

Invasive species should be completely destroyed because they can replace useful native plant species and decrease crop productivity. Some of the invasive species can be poisonous to domestic and wild animals.

1. Purple Loosestrife (Lythrum salicaria)
2. 2. Japanese Honeysuckle (Lonicera japonica)
3. 3. Japanese Barberry (Berberis thunbergii)
4. Norway Maple (Acer platanoides)
5. English Ivy (Hedera helix)
6. Kudzu (Pueraria montana var.

You can kill vines by cutting them down and removing their root systems, or by smothering them with mulch. Vinegar and boiling water are also good, non-toxic options for getting rid of vines. For stubborn, persistent vines, use a systemic herbicide to attack the roots and destroy them for good!

Silver maple tree Silver maple trees have incredibly shallow, fast-growing roots. They might be prized for their vibrant colour in autumn, but their root systems are one of the most invasive of all. As the roots enlarge, silver maple trees have been known to crack driveways, pavements, foundations and pipes.

Worst Trees to Plant Near a House

• White ash (Zones 2-9): A fast-growing shade tree with invasive, lateral roots that’s also susceptible to emerald ash borer!
• Poplar (Zones 3-8): A tall tree with aggressive roots known for causing sewer and foundational damage.

Locating small trees Medium-sized trees can be planted 15 feet from the house and generally 35 or more feet apart. Small trees, such as the flowering dogwood, may be planted as close as 6 feet from the house and about 20 feet apart.

A maple or similarly large tree should not be planted 10 feet from a home. Even doing so for shade means the tree should be planted 20 or more feet from the structure. Planting 10 feet away means the limbs will most certainly be in a constant struggle with the house side.

Sugar maple and red maple—the most common large maples—are not considered to have invasive roots. They have moderate root growth and are safe as long as they’re planted thirty or more feet from any structures.

Red Maples are prized for their silvery bark, fast growth, and yellow-to-red fall foliage. Find your perfect Red Maple! Japanese Maples are a favorite choice for a specimen tree with their typically smaller size, unusual bark, leaf shapes and colors.

Red maple trees should be planted in a location in full sun and ample moisture in the soil. Putting organic mulch around the tree can also aid in holding in moisture. The red maple is best grown in soil that has a pH of neutral to acidic in the range of 3.7 to 7.0.

Some trees are slow growers (20-30 years to reach full size) and some are fast (10-15 years). The good news is that red maples grow at medium speed; in the tree world, this equals about 12-18 inches of height a year.

Red maple is one of the first trees to show off red flowers in the spring and displays a most magnificent scarlet fall color. Red maple is a fast grower without the bad habits of fast growers. It quickly makes shade without the compromise of becoming brittle and messy.

Thanks for your maple tree question. Unfortunately, you can’t control the root size by pruning the foliage. You are correct in saying that the root mass size and tree trunk/branch size are correlated. However, a better plan would be to plant a maple dwarf (Japanese maple, etc.)

Can I Stop My Tree From Growing Taller?

1. Sometimes keeping a tree at its current height is a must.
2. Guidelines.
3. Trim the top of the tree back to within 2 inches where many other limbs are growing from the trunk.
4. Prune back all the other branches in the same section so that the top stay like the rest of the tree.

Trim away the lower branches and shoots on young maples. This will help to shape the trunk to allow for walking clearance under the branches as the tree grows.

Pruning maple trees during the dormant season will help your trees with new growth in the spring when they bloom. You can also prune in the summer if you want to slow the growth of certain branches. This is done to shape the tree, and get rid of any defective or dead branches. Don’t prune your maple trees in the fall.

A shade tree that could be removed is Norway maple. Its seeds fall onto the forest floor and dominate. With that said, if a cultivated Norway maple is planted on your property and is doing well, don’t cut it down.

“Topping” a tree is more like decapitation than a cosmetic procedure, causing serious pruning wounds and destroying the maple’s natural shape. If you own a maple whose upper branches scrape an electric line, you can use crown reduction pruning to reduce the tree’s height.

Chemical Control

1. Purchase an herbicide that uses a concentrated form of the chemicals Dicamba, Glyphosate, Imazapyr or Triclopyr.
2. Plan on treating your maple tree during the early summer or late spring after your maple’s sap has stopped flowing upwards.
3. Spray the cut surface of the stump with the herbicide.
