Weeds That Look Like Small Trees are a common problem in many gardens, and it is not always easy to identify them. Weeds can be difficult to control, as they spread quickly and can take over an area if left unchecked. In this article, we will look at some of the most common weeds that resemble small trees and provide practical advice on how to tackle them. We will also answer some frequently asked questions about these weeds and provide useful tips on how to prevent their growth in the future.
Creeping thistle
Creeping thistle is a perennial weed that can reach up to two metres in height. It has long, spiny stems and usually grows in patches or clumps of several plants. The leaves are deeply divided into lobed segments and have white-tipped spines along their edges. This weed spreads by seed and root, so it’s important to remove the whole patch to prevent it from coming back. To do this, dig out the entire root system and dispose of it in an appropriate manner.[1]
White mulberry
White mulberry is a common weed in gardens and landscapes, and it can quickly take over an area if left unchecked. It grows from underground roots that spread out rapidly, producing multiple trunks and branches that resemble small trees.
The leaves of white mulberry are broad and heart-shaped, with serrated edges. The bark is smooth and greyish-brown in color. White mulberry has small, greenish-white flowers in the spring and red fruits that are edible but not very tasty.
To control white mulberry, you should dig up as much of the root system as possible. It is also important to remove any seedlings before they have a chance to mature. If this proves difficult, you can use an herbicide to kill the weeds.

Make sure to wear gloves and protective eyewear when handling them as their sap can be quite irritating.[2]
Elm trees
Elm trees are another type of weed that look like small trees.
They tend to grow in wet, marshy areas and can become invasive if left unchecked. The best way to get rid of elm trees is by using an herbicide or by cutting them down with a chainsaw. Make sure to wear protective gear such as long pants, boots, and gloves when handling these trees as their sap can be irritating to the skin.[2]
Southern magnolia
The Southern magnolia is a popular ornamental tree that originated in the South and has become widely naturalized across North America. It looks like a small tree with its broad, leathery leaves, but it is actually an evergreen shrub. The Southern magnolia can be tricky to distinguish from other weeds that look similar, so make sure to examine the flower buds, which are white and cup-shaped. It also produces a red cone-like fruit that ripens in the fall.
Sumac (Rhus spp.)

To control Tree-of-Heaven, you can hand-pull young plants and shallowly dig up larger ones. It is also important to remove the seedpods from mature plants to prevent them from spreading. Herbicides such as glyphosate can also be used, but careful application is essential as it can damage other plants.
Golden Rain Tree (Koelreuteria paniculata)
The Golden Rain Tree is a common weed that looks like a small tree. It has multiple trunks, with yellow flowers blooming in the summer and red seedpods appearing later in the season. The leaves are pinnate, meaning they have several leaflets growing from one single stem. This weed is often found growing along roadsides and near buildings, where it can quickly take over an area. It is important to keep it under control, as it can become a nuisance if left unchecked.[1]
Siberian Elm (Ulmus pumila)
One of the most common weeds that looks like a small tree is the Siberian Elm (Ulmus pumila). This weed is native to Asia and has now spread across many parts of North America. It grows in clumps, with its branches spreading up to 20 feet long. Its leaves are usually oval-shaped and have serrated margins. The bark is rough and gray in color.
The Siberian Elm can spread by seed, so it is important to remove the seedlings as soon as they appear. The best way to control this weed is through mechanical removal of its roots or using herbicides. Hand-pulling or digging up the plant can be effective, but it may take several attempts to completely get rid of the plant.
Groundsel (Senecio vulgaris)
Another weed that looks like a small tree is the Groundsel (Senecio vulgaris). This weed is native to Europe and can be found in many parts of North America. It grows in clumps, with its branches spreading up to 6 feet long. Its leaves are usually rounded or oval-shaped and they have a scalloped edge. The bark is light gray in color and has a rough texture.
To prevent the spread of groundsel, it is crucial to eliminate any emerging seedlings. The most effective methods for weed control involve mechanical removal of the roots or the application of herbicides. While hand-pulling or digging up the plant can be effective, it may require multiple attempts to completely eradicate it.[1]
Japanese Knotweed (Fallopia japonica)
This invasive weed is one of the most difficult to eradicate, and it can easily overpower other plants. It has bamboo-like stems with leaves up to 15 cm long. Japanese knotweed can grow up to 3 m tall if left unchecked. The roots can reach down several metres deep and are very hardy, meaning they are difficult to remove fully from the soil.
Buckthorn (Rhamnus cathartica)
Buckthorn is a shrub-like weed found in many gardens. It has dark green leaves and small, black berries that are toxic if eaten. The leaves can be up to 4 inches long and have sawtooth edges. Although it resembles a small tree, buckthorn will not get taller than 10 feet in height.[2]
Privet (Ligustrum spp.)
Privet is a broadleaf, evergreen weed that often looks like a small tree. It grows in dense clusters and can reach heights of up to 12 feet tall. Privet has dark green leaves with white flowers in the summertime. It spreads quickly and can take over an area if not managed properly.
One of the most effective ways to control the spread of Privet is to cut it down. This should be done in the late winter or early spring, when the plant has gone dormant. It is important to remove all of the roots and stems, as this will prevent them from sprouting again.[2]
Japanese Honeysuckle (Lonicera japonica)
Japanese Honeysuckle is a woody, vining weed that can reach heights of up to 10 feet tall. It has dark green leaves with fragrant white flowers in the summertime. Japanese Honeysuckle spreads quickly and can be very difficult to control because it produces large amounts of berries which contain viable seeds.
The best way to control the spread of Japanese Honeysuckle is to cut it down and remove as much of the root system as possible. This should be done in the late winter or early spring, when the plant has gone dormant. It is important to remove all of the berries on the vine before disposing of it, as this will help stop new plants from sprouting up.[2]
Russian Olive (Elaeagnus angustifolia)
Russian Olive is a shrubby, deciduous tree that can grow up to 25 feet tall. It has small silvery leaves with silvery undersides and yellow flowers in spring.
The leaves turn yellow in autumn before falling off. Russian Olive is an invasive species that can spread quickly and take over an area; it often appears near roadsides or areas of disturbed soil. It can be controlled by cutting it back and removing the roots, but it is best to do this before the tree flowers or you risk spreading more seeds.
