My canary island plans are looking bad. Even new fronds are losing color or yellowing. Coastal Mississippi. Any suggestions or ideas please.

Looks like just some cold damage. Nothing to worry about. New fronds should start popping out nice and green. Most people would tell you not to trim the old fronds until they are totally brown. I say trim away until you think it looks ok.

My neighbor way over trims his canary every year,and surprisingly,it does not seem to have any effect on it.

There is a pair of two Canariensises down the road from me. They cut them like that constantly. Every time a frond goes outside the trunk slightly they trim them back. Oh and also they cut the fronds in half as well making them really short. Surprised they are still alive.

Why even keep the palm? Thats a ridiculous pruning schedule lol

@MSGulfcoastI'd guess a combination of cold damage, a magnesium deficiency, and maybe the last couple of months of hot/dry drought.  I'd add some "palm special" type fertilizer, common recommendations on here are PalmGain and Florikan, though I use the generic Vigoro, Lesco and Sunniland palm and ixora fertilizers.  I'd add about 2 handfuls of Magnesium Sulfate (I use Rite-Green brand) to help with the yellowing ends of older leaflets.  Here's my cheat sheet on deficiencies to help diagnose your palm:

• Nitrogen - Older fronds turn light green uniformly, new fronds remain dark green until deficiency is really severe
• Potassium - Older fronds get translucent yellow/orange or dead spots on leaves, especially at the tips. Caryota and Arenga get random splotched dead spots in leaves. Sometimes tips are curled or frizzled. Always starts at tips of oldest leaves, moving inwards
• Magnesium - Yellow ends on oldest leaves first, transitions to solid green at the base of each leaf. Never causes leaf tip necrosis
• Iron - Many times caused by overly mucky soil and root rot. Starts with new spear leaves with yellow-green or even white, possibly with spots of green.
• Manganese - Lengthwise necrotic streaks in leaves with dead and curled leaf tips. Similar to bands showing Magnesium deficiency
• Boron - Bent or necrotic or distorted leaf tips, distorted or bent spear, bands of dead spots on new fans, spears that won't fully open
• Water - Underwatering brown at the edges first, later followed by yellowing of the whole leaf. Overwatering can be drooping fronds turning yellowish and losing color
• Dolomitic Lime or Azomite - Magnesium Carbonate – reduces acidity/raises pH – slower release and adds Magnesium, helps avoid Potassium deficiencies in Cuban Copernicias. 5Lb per palm on full-size Copernicias and a bit less on Kentiopsis Oliviformis
• Garden Lime - Calcium Carbonate – fast release but works well. 5Lb per palm on full-size Copernicias and a bit less on Kentiopsis Oliviformis
• Sunburn - Orange/Red/Brown streaks on surfaces facing the point of hottest sun, typically the worst case is around 1-4pm. Sun tolerant species will adapt and grow out of it. Shade loving species may never adapt.

Thanks for the reply’s.  The one I sent pics of is the smallest of the 5 in the yard so I would hate to lose them. 
planning to start using Jobe’s palm tree fertilizer stakes and see if they improve over summer. 
thanks again 🙂

@MSGulfcoastJobe's spikes are generally not recommended by people on the forum.  It isn't that they are bad, just that they are very expensive for the amount of fertilizer you get.  A 1lb bag of spikes is the same price as a 2lb bag of Palmgain from Amazon.  As a ballpark estimate on fertilizer, the general recommendation is 1.5lb of 8-2-12 for every 100sqft of palm canopy.  A big CIDP like yours is easily 15 feet in canopy diameter = 175sqft of canopy.  That means typically 1.5lb * 175 / 100 = 2.65lb of 8-2-12 fertilizer per palm...4x per year.  That gets expensive fast, especially with Jobe's ($50 per palm per dose) or with small bags of Palmgain ($25 per palm per dose).  It's a main reason I prefer Lesco 13-3-13 palm at 1/10th the price.

[MSGulfcoast]

Thank you. I will see if I can find Palmgain locally before making an Amazon order.

Found a few fronds just folded over near the base. Fronds didn’t look too bad on the outside but inside was brown and rotten. 
what do you all think ?  What could I do to help these palms??

Looks like it is getting to much water. I use soil probiotics consist of seven live bacterias,helps a lot. I’m

Use 100% neem oil, it will take care of the fungus infection

It’s also available at Home Depot online.

@MSGulfcoastthat looks *possibly* a bit more serious than just fertilizer & water.  I say possibly because it could be anything from old hurricane damage, a fungal infection, cold damage, to an infection of LB (Lethal Bronzing aka TPPD - Texas Phoenix Palm Decline)...to the palm "eating" old fronds at the end of winter.  I have seen centers of fronds look like that after cold damage, but that's usually on ones where the leaflets were completely torched and dead. 

What kind of low temperatures did you have over the winter?  I checked the Wunderground history for Gulfport and it shows 23F as a low but highs of only 39-46F for 3 days over the Christmas freeze.  If that's accurate for your house that could explain a lot of the leaf damage...and *maybe* the rachis damage.

If it is a fungal or rachis blight, a systemic like Banrot or Fosetyl-Al may be a good treatment option.

[MSGulfcoast]

Those temps are accurate for this area last winter. I will look for the systemic you mentioned. Thanks.
