Getting Rid of a Sago Palm Tree
A Sago palm tree is a type of evergreen that can quickly spread and take over a garden bed or yard. The palm tree is popular for its pinnate fronds and large ornamental seed head. Yet, the palm tree is actually considered an invasive species in some areas. As such, many homeowners are compelled to take action to eradicate their presence.
Getting rid of a sago palm tree can be difficult, as they are fast-growing and have deep, established roots. The following provides information on how to most effectively and safely handle such a situation.
1. Cut the Frond
The best way to start is by cutting off the frond. This will help prevent the tree from creating more seeds, preventing further spread. Using a chainsaw, the fronds should be cut off at the base of the stem. Make sure to use protective clothing and safety goggles when doing this portion and always follow the manufacturer’s instructions.
2. Dig Up the Roots
After all of the fronds have been removed, you will want to dig up the roots. Sago palms can have roots that go as deep as 12 feet and spread out up to 8 feet. For this reason, it is important to dig up as much of the root as possible. You can use a shovel or an axe to get beneath the root system, while trying to not cut any of the roots. Once the majority of the root system has been uncovered, you can then use a chainsaw to cut up the large sections of root.
3. Kill the Tree
After the roots have been removed, pour a herbicide near the center of the trunk. Use a petroleum-based herbicide that confirms it is a Sago-palm, such as glyphosate. This will prevent the tree from re-sprouting. Make sure to wear protective gloves, as the herbicide is strong and could cause skin irritation.
4. Dispose of Debris
Once the tree has been killed, you’ll need to dispose of the debris. All of the fronds, roots, and trunk of the tree should be bagged up and disposed of properly. Do not put it in your compost, as that will only spread the seeds further. You may want to avoid burning it, as that could potentially spread the herbicide that is on the tree.
Surrounding Landscape
It is also important to consider the surrounding landscape and what impact this tree-removal project may have. Depending on the size of the tree, there could be a lot of soil displacement where the tree was. This could lead to erosion and other unwanted outcomes, so you should plan ahead and contain the debris in an area to prevent it from spreading further.
You may also want to consider putting something in place that will help prevent the Sago palm from returning. Some options for this could include planting a different type of ground cover or laying down somenew mulch. In addition to preventing regrowth, it can also make the affected area more attractive. You should choose something that is heat and drought tolerant, as well as easy to maintain.
Extra Considerations
Depending on the size of the tree, you may need to enlist the help of professional tree removal specialists. They have the right equipment and necessary experience to remove the tree and any accompanying roots safely and effectively. This option may be more expensive, but in the long-run, it can save you time and energy.
In addition to correctly disposing of the debris, you should also take the time to monitor the area for any offshoots that may occur. New shoots may appear where the tree was originally, and you will need to treat them like any other invasive plant. Make sure to pull out any shoots that are spotted and dispose of them.
Environmental Effect of Removing Sago Palms
Removing a Sago palm tree from your yard has both positive and negative environmental effects. On the one hand, removing the tree will help stop it from spreading and reduce the number of Sago palms in your area. On the other hand, it can cause soil erosion and displacement, as well as the potential spread of any herbicides that may have been used.
As much as possible, try to take preventative measures to reduce the impact of the tree-removal process. This includes using a biodegradable herbicide or opting for a chemical-free removal option. Additionally, cover the affected area with some type of ground-covering or mulch, to prevent any invasive species from taking root.
Local Project Management
Before taking on the tree-removal project by yourself, you may want to consider joining a local action group. These organizations typically take on larger invasive-species-removal projects and can provide valuable resources and guidance. In addition to helping you with your Sago palm tree, they also work to educate citizens about different invasive species and their effects on native ecosystems.
Another benefit of joining such a group is being connected with other volunteers. They can provide physical help to the job at hand, as well as additional frame of reference for the situation. This is especially beneficial to those who may not have the right tools or experience to take on the job themselves.
Use of Herbicides
Herbicides are commonly used to kill Sago palms, though many have voiced concerns about their effects. Glyphosate, in particular, has been linked to various health issues, and its use is prohibited in some areas. The environmental risks as well as the potential damage to people and pets must be considered before opting for this removal method.
In lieu of herbicides, some have found success with soiling solarization. This requires the use of black plastic to create a solar-heated environment that kills vegetation and inhibits the spread of invasive species. It is an effective and chemical-free method, and may be the best way to go for those who are more averse to using herbicides.
Spreading Seeds
One of the main reasons why Sago palms should be removed is their propensity to spread seeds. Seeds can go unnoticed in the soil or accidentally be transported somewhere else by wildlife. The presence of seeds can cause a rapid increase in the number of Sago palms in an area and must be taken into consideration during the removal process.
When disposing of the debris, be sure to check for any potential seeds and dispose of them. Be vigilant and monitor the area for new shoots, as these are often the first sign of new trees being formed. Address them promptly and behave as you would with any other invasive species.
Preserve Properties
Sago palms can quickly dominate an area and significantly reduce the number of native plants. Not only does this limit the types of plants that can grow in that area, but it can also degrade the overall property value. It is important to take action when dealing with Sago palms so as to not let their presence spread any further.
You may want to consider using a pesticide to help keep the Sago palm population under control. However, opt for one that is pet-friendly and has minimal environmental impact. Additionally, you can introduce plants that can compete with the Sago palm, such as the Brazilian pepper or thimbleweed, which have been found to be effective in certain areas.
