Thanks for your query Lisa.

If you no longer want your Canary Island Date Palm, removal rather than killing the plant and leaving in situ is generally the safer option. Killing a palm will lead to its structural deterioration; falling fronds or the collapse of the entire head from an established palm can be dangerous. I suggest you contact a local arborist to arrange its removal.
Regards,
James

How do I kill/ poison one of these plants quickly?

Hello Clare. Solitary palms have only one apical meristem (bud) generally located in the center of the crown immediately below the emerging central leaf spears (young leaves). If this bud is killed or severely damaged, the palm will die. Damage to the bud may not become apparent for up to 18 months following injury.

Hope this helps

Hi,

I’ve successfully had a rant at a neighbor in the process of cutting down a CIDP, the palm still stands.

Just curious how one would date (no pun intended) the tree. Its about 9m tall and trunk is >1m diameter half way up – very majestic.

Thanks

Clare

Thanks Penny for the comment.

All palms that develop a trunk regardless of species will not do so until the root initiation zone and apical bud are fully developed. This process can span a number of years depending on local environmental conditions and climate.

When pruning palms, only remove dead, dying, yellow, brown or broken fronds; flower and fruit stalks. Remove loose petioles or boots by hand. If they don’t pull off, leave them on. Palms must never be topped. Solitary palms have only one apical bud. Once the bud is damaged or killed so is the entire palm. The buds of CIDP are between 40 to 60 centimeters from the emergent point of the central leaf spears at the top of the trunk.

Moving palms requires a certain level of expertise and heavy machinery as even small palms like the one you have identified can weigh as much as 3 tonnes. You are best getting an expert (such as Tree Logic) to assist.

I have a 22 – 25 year old ? canary date palm that has not grown a trunk. The base of the palm is approx 800mm in diameter and the top of the central fronds are approx 8 metres from the ground. Is this a certain species that doesn’t go up? Or is it because I’ve only started pruning it regularly in the last few years? Also I am interested in moving it in the garden approximately 6 metres from it’s current position. How is the best way of going about this? I am on the mornington peninsula – westernport bay side.

Hi Randy,

Without seeing the palms, your description ‘whitish powdery tufts on the older fronds’ does sound insect in nature, possibly a mealybug.

The symptoms observed in older fronds including staining of the frond stem (rachis) and one-sided death of the leaf blade are symptoms common to the diseases Fusarium Wilt and Rachis Blight, both of which affect Canary Island Date Palms. For accurate diagnosis and guidance on appropriate control measures, I suggest you engage the service of a local and suitably experienced arborist.

Best wishes,

James

Hi. Great site.
I have several dozen CDIP’s that I grew from seed. The largest is over 3 meters tall. It has whitish powdery tufts on the older fronds. They don’t look like any scale or mealy bug pics I’ve ever seen. Additionally, several older fronds on one side develop dark line running down length of frond, dry out and die within days. Still has new growth from crown but it has slowed and looks smaller than usual. Is this Fusarium wilt? Any advice is appreciated.

Thanks for your query Emma,

The seedlings you are observing can indeed develop into mature palms. Although the CIDP is a slow growing species, for ease of removal it is prudent to remove unwanted seedlings as they appear.

Quite a number of the seeds fallen from my CIDP are starting to sprout shoots. What is the likelihood that these could grow into mature trees? I have just been pulling them as I don’t want them to grow.
