Brown spots on small Trachies
Brown spots on small Trachies
I have a couple of in the ground Trachies. They are small, only a couple of years old but both are covered in small brown spots. I presume its a fungus or something similar. How can I treat it?

Re: Brown spots on small Trachies
Cut the worst leaves off and spray with a fungicide in autumn and spring. Also don't over water and crowd out with competing plants.
Re: Brown spots on small Trachies
Thanks Kris. Most leaves are badly affected so ill cut them off. What make of fungicide shall i get?

Re: Brown spots on small Trachies
I think it's a plant rescue one that I've got I've lost a few Trachycarpus seedlings to fungus spotting Not so bad on larger palms that can recover. Some palms are worse than others. I have a butia that gets spotting every spring.
Re: Brown spots on small Trachies
Mine are brown Tom, I think mine dried out over winter or got caught with frost,

All of my butias get spotting every year now.Yorkshire Kris wrote: I have a butia that gets spotting every spring.
Re: Brown spots on small Trachies
Thanks, I will have a look for some. Its just my two smallest which are east facing so I'm guessing the very long cold winter has taken its toll on them for some reason. My west facing and three potted are so far looking good.Yorkshire Kris wrote:I think it's a plant rescue one that I've got I've lost a few Trachycarpus seedlings to fungus spotting Not so bad on larger palms that can recover.

Re: Brown spots on small Trachies
You should probably be sure it's not a deficiency (could be caused by soil conditions, too wet, too cold, or too much of a particular kind of nutrient) before you go removing all the damaged leaves as in this case you'd only make the problem worse.

Re: Brown spots on small Trachies
Thanks very much for the link
I think you may be right about soil, mine are brown along the spear..neglected and too much wet for yunguns does'nt help in my case.
Odd one is ok.
Both been out all winter.

Re: Brown spots on small Trachies
I might pot them up and see if I can improve them, what do you reckon?Vagetarian wrote:You should probably be sure it's not a deficiency (could be caused by soil conditions, too wet, too cold, or too much of a particular kind of nutrient) before you go removing all the damaged leaves as in this case you'd only make the problem worse.

Re: Brown spots on small Trachies
Exactly the same thing with my Trachycarpus seedlings.
Think the mould / markings are just a result of cold and damp, but they're now recovering in the sunshine / warmth and sending up healthy looking new leaves (can't really call the emerging leaves spears at that size).

Re: Brown spots on small Trachies
Kata, I would guess that your diagnosis is fairly correct there. It doesn't look like any pathogen to me because the pattern of the damage is far from random, it's concentrated towards the middle/end of the leaflets.
Tom, I'm certainly no palm disease expert, in fact, the only palm I have outside is 1 Butia and my only Trachycarpus is a little seedling. Even if I were and I had the palm in front of me and went through the excellent symptom checker that I linked, I'd probably still be left scratching my head.
Is the spotting concentrated in any particular areas on the whole plant and on the affected leaves?
All I can really say is don't rush into anything you're unsure of. I tried battling a pathogen once and eventually I realised that it was a nutrient problem caused by too much insanely hard tap water. It's really hard to tell and all plants show symptoms in quite different ways, even different palm species have wildly varying deficiency symptoms.

Re: Brown spots on small Trachies
I have decrative stones in the marked spear one, no stones in the clear one,
The lime in the stones could be another reason I guess.
Too wet, too cold, neglect in winter and possible lime damage..

Re: Brown spots on small Trachies
I don't know if it's particularly sensitive to alkaline soils, it's probably just the cold and wet. I was just pointing out how you can get things wrong easily (or maybe it's just me ).
Re: Brown spots on small Trachies
I don't know what soil Trachis like either...
Lets agree its the soil and wet
