Palms are monocotyledonous plants, which means they do not possess the ability to regenerate from the top portion of the tree if it’s cut off. Unlike many other types of trees, palms do not have branches or secondary growth points (meristems) that can develop into new trunks or stems.
However, some palm species may be able to produce new growth from the lower part of the trunk or the base of the tree if the growing point (known as the apical meristem) is still intact. This new growth is known as “suckers” or “offshoots.” Whether a palm tree will produce suckers and survive after being cut in half depends on the specific palm species, the health of the tree, and the severity of the cut.
In many cases, severe cutting or damage to a palm tree can be detrimental to its overall health and survival. It’s generally advisable to avoid cutting palm trees unless it is necessary for safety reasons or as part of a planned pruning process. If you need to trim or remove a palm tree, it’s best to consult with a professional arborist or a tree care specialist who can assess the tree’s condition and provide guidance on the appropriate course of action.
When it comes to severing off the growing tip or better know as the ‘crownshaft’ of any Single-Truck palm species, will in short effectively terminates the life of the palm tree. The trunk will not be able to sprout a new growing tip in place of the old missing crownshaft, and without the extra foliage to synthesize the incoming light, the palm soon grows weak and the entire trunk system starts to rot. If you do end up having to cut off the top of any single-trunked palms or if any sort of damage happens to it, the next initial move would be to remove the remainder of the palm tree trunk and root system and completely restart with a brand new tree.
Some examples of single-trunk palms include the Mexican fan Palm, Royal palm, Christmas Palm, and the Cabbage palm. These are all great options to choose from when choosing which Single-Trunk palm to birth.
Clustering palms are incredibly unique and grow multiple trunk stems, this means you can shave away some trunks without ending the plants’ life. In any case if the individual palm trunk is removed solely, it will not be able to heal itself. Even if you where to make the decision to cut off the trunks on the palm near the root level, suckering explodes from this root level and will eventually sprout and develop into new healthy palm tree trunks. The suckering process and rejuvenation will only happen in the case of a healthy clustering palm. On the other hand, diseased on distressed palms may not create new suckers and may eventually end up dying.
Palm trees are iconic symbols of tropical landscapes, known for their tall, slender trunks and crown of feather-like fronds. While most palm species grow as solitary trunks, some varieties produce new shoots or suckers from the base or trunk. These offshoots allow the palm to propagate naturally, but could also indicate underlying health issues. This article provides a complete overview on palm tree shoots emerging from the trunk, including why it happens, which species are prone to suckering, and how to manage extra growth.
What Causes Shoots on Palm Trunks?
There are a few key reasons why a palm tree might send up new shoots from the trunk:
-
Natural growth habit Certain palm species, like sago palms (Cycas revoluta) and European fan palms (Chamaerops humilis), naturally produce basal suckers as part of their growth cycle This allows them to expand via asexual reproduction
-
Injury response Palms may generate new shoots in response to damage, whether from pruning, storms, pests, or disease The sucker growth helps the plant recover vigor after trauma
-
Cultural problems: Issues like overwatering, poor drainage, compacted roots, or mineral deficiencies can all spur excess shoot growth from the trunk. This is the palm’s attempt to gain more resources.
-
Genetic predisposition: Some individual palms are genetically prone to developing more basal suckers than others of the same species. This tendency gets passed down.
Palm Species that Commonly Sucker
While any palm can send up shoots when stressed, certain varieties are more genetically predisposed to sucker growth whether conditions are ideal or not. Some palms known to frequently produce basal shoots include:
- Sago palm (Cycas revoluta)
- European fan palm (Chamaerops humilis)
- Chinese fan palm (Livistona chinensis)
- Fishtail palm (Caryota mitis)
- Spindle palm (Hyophorbe verschaffeltii)
- Triangle palm (Dypsis decaryi)
- Christmas palm (Adonidia merrillii)
- Manaca palm (Euterpe edulis)
Managing Palm Suckers
If your palm starts sending up shoots from the trunk, you have a couple options on how to manage the growth:
-
Remove suckers – Cut or pull shoots as soon as they emerge to maintain a single trunk. Use sterilized pruners and seal wounds.
-
Leave suckers – Allow shoots to develop into new palms if desired. Space at least 3 feet apart once established.
-
Address underlying causes – Determine if growing conditions like irrigation, drainage or fertilization need adjustment to discourage excess sucker growth.
-
Consider trunk barriers – Wrapping palm trunks with aluminum sheeting, landscape fabric or other material can physically block new shoots. Monitor for pests.
How to Remove Palm Shoots
If choosing to eliminate emerging palm suckers, follow these tips for safe, effective removal:
-
Time it right – Prune offshoots when small, before they lignify and attach to the trunk. Remove at soil level.
-
Use proper tools – Sharp sterilized pruners or saws reduce damage versus tearing shoots off by hand.
-
Cut carefully – Make clean cuts without leaving stubs to prevent disease infection. Avoid harming the trunk.
-
Apply wound sealant – Coat cut areas with tree paint or sealant to protect from borers and pathogens.
-
Remove growth rings – Eliminate rings of shoot bases circling trunks, which can girdle palms.
-
Check for pest damage – Inspect carefully for signs of rot or insect borers when removing suckers.
-
Monitor progress – Continue checking for and removing new shoots as they emerge to control growth.
Can You Replant Palm Suckers?
Mature, lignified palm shoots with their own root initials can potentially be separated and replanted. However, the sucker size, health, and root development must be adequate for it to survive transplanting. Requirements vary by species, but sago palm shoots often need a 1-2 inch diameter trunk and established roots for the best replanting success. Always use clean, sharp tools to remove suckers to avoid harming the parent palm. Monitor for signs of distress, and have a backup plan if the sucker fails to establish on its own roots.
When to Worry About Palm Trunk Shoots
Occasional sucker growth is normal, but excessive or rapid shoot development could indicate an underlying issue. Contact an arborist if your palm displays these warning signs:
- Numerous new shoots emerging suddenly
- Shoots surrounded by soft, wet spots on trunk
- Shoots with foul odor, gum or oozing
- Presence of pests like palm weevils or borers
- Wilting, off-color or dying fronds
These symptoms suggest problems like anaerobic root rot, lethal bronzing disease, or red palm mite damage. Proper diagnosis and treatment is key to saving the palm. Desperate sucker growth is the tree’s last attempt to stay alive.
While palm trunk shoots are not necessarily detrimental, keeping growth under control enhances the ornamental appearance and health of palms on the landscape. Monitor for new suckers, determine if removal is preferred, and be ready to address any underlying cultural issues contributing to excessive production. With some vigilance and prompt pruning, you can guide your palm trees to grow strong and tall as stunning solo specimens.
Palm Tree Trunk Wounds
Naturally Palm trees lack cambium – which is a layer of tissue behind the tree bark that creates the growth rings in the tree. Any wounds inflicted to the trunk of a palm tree cannot repair itself meaning these wounds will remain with the palm for the rest of its life. The wounds can and most likely will become dry and brittle unless weather conditions are full of rain or high humidity which can prevent the wounds from drying out. If it is not obvious enough, Insects and fungal infections can penetrate the palm and cause massive damage to the plant’s articular system.
When it comes to the pruning aspect of the palm tree there are crucial factors that come into play during this process. One being that it is important to never sever the downshaft on a palm. Another tip is to remove just the right amount of fronds, or you may just stunt your palms growth, and an obvious one– never introduce any sort of diseases to the plants. In short palm pruning can be hard to manage and is better left to the professionals. If you do decide to proceed with pruning the palm yourself, go ahead and remove only the broken fronds that are entirely dead with no color left to them. Also removing flowers and/or fruit is acceptable and gives the palm more energy to spend time creating new leaves.

FAQ
How to get rid of palm tree shoots?
To kill seedlings that are already growing, use an herbicide that works on woody plants, with active ingredients such as triclopyr or picloram. Roundup (i.e., glyphosate) will NOT be effective on palm seedlings. Be sure to read any herbicide label in its entirety prior to applying the product. It’s the law!
Why is my tree sprouting from the trunk?
Trees grow water sprouts from the trunk when the tree is under stress. Dormant buds under the bark start growing when the tree has lost its top, if the roots are constricted, or during times when other stressors threaten its life.
How to tell if a palm tree has died?
Signs of a Dead Palm Tree
No new growth: A healthy palm tree will have new fronds emerging from the crown. If you notice that no new fronds are growing, it could signify that the tree is dead. Brown or yellow fronds: Palm fronds that are brown or yellow are usually a sign of a dead or dying palm tree.
