The freezing rain last week across the panhandle left icicles hanging from street signs, rooftops, trees, shrubs and palms. Many people now wonder if their palms will survive the assault of the hard freeze. The chance of survival depends on the following factors:
- the most important consideration is the species of palm; a few of the most cold tolerant that are more readily available are pindo palm, mule palm, European fan palm, Chinese fan palm, needle palm, cabbage palm, and dwarf palmetto
- whether the palm is in an area protected by other vegetation or buildings
- proper fertilization with 8-2-12-4 has been followed
- palms have been properly pruned, i.e. only dead fronds have been removed from the crown (overtrimming by removing green fronds is a stress to the palm)
The best approach is to leave the palm alone until all danger of frost or freeze is past. Avoid the temptation to remove any of the dead fronds; they will help insulate and protect the meristem, or bud, that will produce new shoots.
If the palm is not too tall, in the spring check to see if the spear leaf (the newest frond that usually stands straight up and has not opened) can be easily pulled out. If the spear leaf does not pull out, the likelihood that the palm has survived is good. Don’t despair if the spear leaf does pull out as the meristem below it may still survive. The best strategy in that event is to remove the dead spear leaf and treat the bud area below the spear leaf with a copper fungicide to reduce the chance of infection of the bud. Be sure to use a copper fungicide and not a copper fertilizer, like copper sulfate.
Once spring comes and you find that the palms have survived, don’t be alarmed if the first new frond is deformed or has dead tips. The fronds that follow will most likely be normal. The palm will be building its depleted food reserves with new leaves so do not remove any fronds that have any green on them whatsoever. All green tissue is making food for the palm and helping it to recover from the cold stress. Only remove fronds that have completely died and have no green tissue.
When temperatures warm and the palms are actively growing, apply a palm fertilizer with the formulation of 8-2-12-4 with micronutrients.

Thank you so much for your reply. I think I will leave them grow for now because I don’t have space in my garden.
August 15, 2019
Your description sounds like the plant is making 'pups'. This is normal. You can leave it be and you will have a multi-trunked sago or you can remove the pup and plant it elsewhere. To remove the pup, gently pull back the soil and cut off the pup vertically with a sharp shovel or blade in order to get as much of the pup as possible without harming the trunk of the original sago. Let it dry in a shady area for a day or so and then plant in a pot or directly into a planting bed. Keep moist but not too wet while it gets established.

Hi, i need help with my sago palm. Today i noticed new leaves coming out from under the ground very close to the trunk. Is it normal? or i did something wrong? thank you
June 25, 2018
The sago may be experiencing a boron deficiency. The heavy spring and summer rains could have leached the boron from the soil. Dissolve about 2 oz. of Borax in 5 gallons of water and drench the soil all under the canopy. The next set of leaves should be normal. It may be helpful to also apply a general purpose controlled release fertilizer at the same time.
June 23, 2018
Note: a smaller sago I transplanted a few feet away is growing back normally.
June 23, 2018
I have an older sago palm that I moved from one part of my garden to another last year. It did find through the year but ll the fronds got killed off in the harsh winter we had in Virginia Beach despite wrapping and covering in burlap. New fronds just started growing out, but many of the fronds are a slightly lighter shade of green and the needles on many are mutated. They are very wide and rectangular or growing forked. I've grown sagos for many years and have never seen this before. Has anybody experienced something like this?

Lubber grasshopper candy. Some years I couldn't get a bloom because the plant was eaten down to the ground.
August 22, 2016
Yes, please send some pictures to me at mderrick@ufl.edu. Include an overall photo of the landscape and then some closer shots of the plants. Also let me know what was done recently in the landscape, including fertilizing and any other products used in the vicinity.
August 22, 2016
Ms. Derrick, I had 3 beautiful Sagos that are over a decade. I had my front yard re done new soil new plants etc. They all look like they are dying all of a sudden. Would you mind if I sent you some pics? Thanks You Joanna
July 27, 2016
Mary - thank you - I have several Bromeliads and immediately went out to empty. Did not occur to me this would be a place for a mosquito. I, definitely, learned from reading your article! Jeanne Blage, M.G.

Mary, My sago does not look as bad as your picture. My leaves look as if there is rust on them. Could this also be manganese deficiency? Thank You for your time. Oscie Smith
May 3, 2016
The problem does not sound like a manganese deficiency. The yellowing bottom leaves could be from overwatering. Sagos need to dry out a bit between thorough waterings. When you transplanted the sago, is it sitting at the same soil level as before? Planting at a deeper level can be damaging to the plant. Many commercial potting mixes already have a 3 or 6 month controlled-release fertilizer incorporated into the mix and no further fertilizer should be used until after that time frame is passed. Remember that sagos can take full sun; I don't know how much sun it was getting before purchase but you may gradually want to move it to more sun if it is in a shaded location. Sagos are tough plants and will survive the loss of some leaves.

my bottom leaves turned yellow only 2 days after a trasnplant and not are at the point of Frizzle bottom? every artice i see mentions the top leaves tunring yellow not the bottom but then some have pictures saying both are examples of manganese defincienty. just to be clear if my bottom leaves are turning yellow just like the frizzletop symptoms Is that a sign of mangenese defiencienty?? i need to treat it but i want too be sure i do the right thing. i just applied about 2 tablespoons of mangenese sulfate and appied some direcetly on the leaves as well. will this treat the problem? i ony got it 4 weeks ago it was in perfect condition until 2 to 3 days after i transpanted into a bigger pot because the roots where growing out of the old pots drainage holes. I used all purpose potting soil and organic fertalizer until i realized it didnt have the required nutriets. now i switched to palm gain a 8-2-12 fertalizer made for cycads and palms and i also added the magenese sulfate

Some of my sasanquas had leaf gall as you have described. My friend Jim told me about your recommended cure and following his recommendations seems to have cured my problem. Thanks for your view.
April 30, 2016
Hi Mary I have emailed you a photo of my plant and am hoping you can help. It was beautiful before I botched it! Allison
April 21, 2016
It's hard to tell from your description what is going on with your sago. Sometimes when lower leaves of a plant have a black coating it is sooty mold that grows on honeydew excreted by insect pests feeding on the undersides of leaves higher up in the canopy. Treating the insects will eventually eliminate the sooty mold. Inspect your sago carefully and email photos to me at mderrick@ufl.edu.
April 12, 2016
I have a sago palm that the lower palms are turning black. Can you tell me what I can do? It is in a container and I need to transplant it. Is it still OK. Thanks Miriam

There's nothing like relaxing in my garden after a tough day at work. I have a couple of night blooming flowers like four-o-clocks, evening primrose and moonflowers that instantly brighten up my mood when I sit in the garden after dinner. I'm just mesmerised by the lovely blooms that open up at night. Thanks for sharing ideas that can help me enhance my night garden. Will definitely try planting some of the plants you suggest. Desiree

The yellow-brown sponge material is a natural feature of the plant, most likely yours is a female sago. Yes, sagos are either male or female plants. The leaves may be yellowing from lack of light - they like full sun so place it in a very sunny part of your home. Maybe it can stay outside unless it is freezing. You can send photos to me at mderrick@ufl.edu
December 30, 2015
Some fruit trees/bushes that do well in our area with minimal maintenance are fig, Satsuma tangerine, kumquat, persimmon, blueberry, blackberry, muscadine grape. Low-chill varieties of apple, pear, peach, nectarine can be grown but require regular specialized pruning and spraying. Go to gardeningsolutions.ifas.ufl.edu and look under the 'edible fruit' tab. Lots of great info there!

Can you please help me!! i have 2 Sago palms and both of them have yellow-brown sponge like material in the crown of the plant and the leaves are starting to turn yellow. I live in VA and moved the plants indoors for the season about a month back. Is it from overwatering leading to crowm rot? Pl help and how can i attach a picture?
November 10, 2015
Thanks for your response and the tips! Yes, it looks very much like the one in the picture above. I can take some pics tomorrow to send. Ours doesn't have any older fronds on the bottom because we trimmed them all off when the new leaves came out... They looked bad too, but we didn't realize it would be a continuing problem at the time.
November 9, 2015
It sounds like it may well be a manganese deficiency - does it look like my photo in the article? You can send a photo or two to me at mderrick@ufl.edu to confirm. If it is confirmed, for a sago of that size I would spread about 3 pounds of the product evenly under the canopy of the sago and water in well. I would also do a light application of a good quality palm fertilizer like I describe in the article.
November 9, 2015
Hi! We moved into our house this past summer and the sago palm was already established and has probably been here for several years. It's between the front of the house (north facing) and our sidewalk. It finally sprouted some beautiful green fronds this August and within a few weeks they started turning yellow and now brown in the center. I haven't noticed any pests and we haven't treated it or fertilized it yet. I bought some manganese sulfate today to try treating it. I'm in Jacksonville, FL. Is it likely a manganese deficiency? If so, how much should I use? Should I spray it on the plant or put it in the ground around it, or both? The palm is about 4 ft tall and 3-4 ft wide including fronds, the stem/trunk is about 8in in diameter. Thank you for your time and any advice you have!
October 23, 2015
Most refer to it as Cogongrass but some other common names are Japanese bloodgrass, japgrass, and Red Baron grass.
October 17, 2015
Mary, would I know this by another name?
September 26, 2015
Excellent article! I really enjoyed reading it and the content was very informative. The link to more info was also very good. Thanks!
September 23, 2015
Start with clean, sharp pruners or loppers (depends on the size of the fronds) and make cuts close to the trunk. Pruning tools should be cleaned with alcohol or a 10% bleach solution before using to prevent the introduction of disease into the pruning cuts. How many fronds to remove depends on your personal preference. However, remember that the green plant tissue is making food for the plant through photosynthesis and you want to keep the healthy green fronds.

My sago palm is all yellow-brown in middle it is 2ft high in middle of yard in Florida. Is the low magnisium the problem?the outside is green I notice spiders in there could they cause the browning?
July 16, 2015
I live in coastal NC (Wilmington) and my sago palm, which has been doing well for years, has taken a turn for the worse. We had two severe winters, which killed the palm to the east side of the sago, but not the palm on the west side. I do not note any sign of scale on the fronds, The older fronds are turning yellow and becoming crispy. The new fronds are (so far) fine. Frost damage? Low manganese? Too much sun? It is in a moist part of the yard, but the drainage is okay, and, like I said, it has done well for years. Thanks. I can send a photo if that helps. Thanks so much for any help!
June 26, 2015
Ill be sending a few shots of my sago with up close of core which newly sprouted but seems to have scale. Thanks for any advise on how to treat it. In sending them tomderrick@ufl.edu Thanks! Doris

Thank you for your comments about scent in the evening garden. They do add to the experience. The datura are showy and fragrant at night but be cautioned; datura is toxic when ingested and can be irritating to some when handled.
June 24, 2015
An excellent article on what and how to plant for a visually appealing evening garden; the mention of sound was nice, as well. But what about fragrance? You can smell flowers you can't see at night, as well as some you can. Some four o'clocks are fragrant, but apparently some are not. One cultivar of Datura inoxia (Datura meteloides) 'Evening Fragrance' has an intoxicating fragrance; moreover it's flower is white and showy. Nicotianas are fragrant at night, too, and some have white flowers. Certain ginger lilies will also perfume the evening garden. And, of course, roses, though some of those are more fragrant than others.
June 19, 2015
Yes, please send me some good photos and let's work on determining the cause and remedy for the problem.
June 19, 2015
I've read through the info and all the comments and think my sad looking Ssgo which had been doing wonderfully in a pot a short while ago has been over watered which has made it susceptiple to pests or disease. I would like to send you a photo if that's ok. I would like to be able to treat the plant and restore it to its original beauty if possible. Any help you could provide would be appreciated. Thank you!

Sharpened really refers to a older blade, when dull "sharpened" to as near new condition as possible or replaced.

What is a sharp mower blade? When I buy a new one it should be correct, but I certainly wouldn\'t call it sharp.

Not sure how to add a photo but my Sago Palms have all dried on the tips of the leaves. And a few leaves dried and died completely. The Candle Pine alongside has died suddenly too. It appears poisoning has occurred. Will the Manganese Sulfate help at all. There is a little life left in them so need help and any advice please to try nurture them back. Thank you.

Unfortunately there is not a silver bullet option as far as disease control goes for fruit trees. A good place to start would be with copper, chlorothalonil (such as Daconil), and Captan. And remember many of the diseases begin when the buds begin to swell so sprays must be applied at bud swell and during flowering.
April 19, 2015
Is there one spray that will work on apples, pears, peaches, plums, nectarines, pecans? I have a small orchard and would like to know when, and what I need to spray on my fruit trees. Also, is there a more natural way to counter pests, diseases, fungus?
March 27, 2015
Doug, Hope things are going well for you. I will keep in mind your farm. Occasionally people ask me about farm land. Where are you moving?
March 27, 2015
Hi Blake. Thanks for the article. My lawn is the pits. One big sand pit. this past early summer i removed our above ground pool that we put in some 20+ years ago. All that has grown is plants with leaves. nothing with a blade. This past fall I broad cast rye grass that has come up. but not seeded as yet. I have a long tradition of not mowing the lawn before Easter so I have places to hide Easter Eggs for the kids. Will get soil samples to the Ext. Office today. Incidentally. I have approx 3 acres fenced and cross fence on the front of my place which I have one acre that I will be planting Sun Hemp the end of April. It was a beautiful yellow this past fall and my goats loved it. Will try to set up to see if it will product a honey crop as claimed by some. Currently I do not make any honey crop even for winter surplus here at my place. After the Spring Titi bloom goes to seed that is it for the bee's. Know anyone looking to buy a farm. We are zoned Agricultural, 3 acres fenced, 7 miles from a grocery store.

February 28, 2015
We are in Bay County, Panama City Beach, FL. So, now is a good time to do any trimming/cutting back on the knock out roses?
February 27, 2015
For trimming Knockout roses, there are several schools to thought. I would first remove any dead wood or crossing canes, and cut the remainder back by 1/2. Some people allow their Knockout roses to grow without any pruning and some prune them directly with hedge trimmers. They will do well under several different care regimes and are quite accustomed to minimal care. This is the dormant period, roses are not expected to be green all year. If it does not green up, contact your local extension office with a sample or contact your agent. What county are you in?
February 27, 2015
It's best to apply the preemergence herbicide now and then fertilize AFTER April 15. The turfgrass should be fully out of winter dormancy and growing before fertilizing. Also, I recommend a lawn fertilizer that is a 15-0-15 or 15-2-15. The nitrogen (first number) and potassium (third number) should be balanced for best results.
February 26, 2015
Thanks for the response. So I should apply a preemergence herbicide now and then fertilize by mid April, correct? Do I need to wait a certain time after the herbicide to fertilize? A week?
February 26, 2015
In North Florida, your lawn should be fertilized no sooner than mid-April. The lawn should be already actively growing and mowed at least once before fertilizing. Fertilizer applied too early can run off or leach down through our sandy soils before the grass has a chance to use it. Please see http://gardeningsolutions.ifas.ufl.edu/lawns/ for more information on fertilizing your particular turfgrass.
February 26, 2015
After you apply a preemergence herbicide, when should you apply a fertilizer for the lawn?
February 24, 2015
When should I trim back my knock out roses? Do I also cut down to the ground the new growth of cranes that have reached the same height as the original height of the rose bush? What makes one rose bush have very few leaves?

The green sprouts are pups that can be removed to form a new plant or they can be left in place to form a clump of sagos. I have some questions about the yellowing of the leaves before I can determine the cause and, thus, the action you should take. Did the sago leaf out normally this spring and have normal green leaves until recently? Have you closely inspected the leaves to search for any pests? Where is the sago in your landscape - in a landscape bed, surrounded by turf, next to a building, etc? How do the other surrounding plants look? Have you applied any fertilizer, insecticide or herbicide in the area? Generally, sagos do not need supplemental fertilization. I see them quite often in unattended landscapes looking quite healthy. You can send a photo to me at mderrick@ufl.edu and that may be helpful.
September 5, 2014
I have a sago palm and all the leaves turned yellow. There are green sprouts coming out at bottom of sago. I live in North Carolina and have only had the tree two years. Should I cut off the yellow leaves to allow the green leaves to grow? Should I fertilize? We had two rough snows this year and lately alot of rain. I have read mixed reviews on whether to cut the yellowed leaves but I dont want to inhibit the new green growth with the dying yellow leaves.

September 25, 2013
Thank you, Vic, for sharing your experiences with using manganese sulfate! You don't mention how your sago palm responded to the treatment but I infer that it responded well to the manganese sulfate application. You are correct in saying that the rain helped wash some of the excess manganese from the soil; sandy soils will allow much of it to leach although rich, organic soils will hold onto it more tightly. This is a good reminder to all to use manganese sulfate and all other fertilizers according to professional recommendations and according to label directions. If you have not done it lately, I would encourage you to have a soil test for pH and nutrient levels through the University of Florida soils lab in Gainesville. Your local extension agent can give you the kit for sending in your soil. Different plants have varying responses to high levels of nutrients in fertilizers. Some can tolerate it well and others are very sensitive. It seems you learned that first hand. One of the major symptoms of manganese toxicity is the chlorosis (yellowing) of leaves starting with the new leaves. This happens because excess manganese interferes with the absorption of iron and the plant will develop an induced iron deficiency. Other symptoms are dead brown spots on older leaves with yellowing areas around them, delayed fruit ripening, and distortion of new leaves. For more information please see: Touria El‐Jaoual & Douglas A. Cox (1998) Manganese toxicity in plants, Journal of Plant Nutrition, 21:2, 353-386.
September 25, 2013
Good atricle. I think they nailed it. Manganese toxicity. I am thinking the excess rain has helped as much as anything to leech out the overdose and I may add some dolomitic lime to a few of the plants.

Thanks for the sago nutrient tips. I read this after the fact but it is essentially what I did. I saw the commercial manganese sulphate bags at the store and got one (has a sago or palm on the bag). Here is my question. I had a fair amount of manganese sulphate left over and so I just dosed a little at other plants around the house. Probably a bad idea. MOST of the plants handled it fine. But a few took a sudden shock hit body blow. YEllowed up and knocked back a gardenia. Of three near each ohter only one was hit hard and it yellowed bad and browned and lost leaves. It might yet survive but the other two ether side will eventually fill in anyway. The other plant that took it poorly was a very nice Jasmine (larger leaf kind) that I'd transplanted about three years ago. It was doing well but after this it began to turn red leaved and the leaves died off. AS they died off, new leaf buds were and continue to push out from the branches and the ends of the crawling vines maintained greed and grew. I don't think I killed it but it was close. It is slowly recovering. I had some yellow splotches of grass that had not responded to ammonium nitrate so I threw some manganese sulphate on those areas too. Just about killed it out - was brown in a week. But it is greening up again and will be ok in a few more weeks. I had used Aluminum Sulphate (I think) a couple of years ago to "acidify" some soil I had erroniously applied lime to and it worked great to save my centipede grass - which I now know liles acid soil. Anyway - the Aluminum Sulphate did the trick that time (made it more acid). But the manganese sulphate was did not play well with the grass. There was PLENTY Of rain after this application. And for weeks afterward. I think the rain allowed the sudden hit of acidic soil which shocked the sensitive plants but after more time -- the added rain has at last diluted some of the effect and the plants are in recovery. So that is my story. Mr. "Never leave a partial bag when you can throw it all out and be done with it".

Mr. Gold, There should be little concern as long as the harvest aid materials are applied to the target site according to label directions. Most labels give specific directions for the applicator to follow regarding equipment use, weather considerations, and other factors to prevent drift. However, since cotton harvest aids work by either herbicidal or plant hormonal activity there is the potential for injury to non-target plants and other organisms if drift does occur. Most of the products used are not persistent in the environment and other crops can be planted in treated areas within a specified re-crop interval listed on the label.

Hello Mr. Donahoe: Thank you for your very informative article on 2013 Cotton Harvest Timing and Defoliation. I currently lease a portion of my property to farmers in Okaloosa County. They normally rotate their crop annually between cotton and peanuts. This year they are cultivating cotton. In the past, I have been concerned about the defoliation phase of the crop cycle on my property since I attempt to maintain the non-cultivated acreage in a more natural state conducive for indigenous fauna and floral. Specifically, I would like to know if any of the defoliants used are harmful to the natural non-cultivated acreage, and to the ecosystem of a surface pond on my property that acts as a watershed for the surrounding area? Thank you in advance for your time and consideration to my question. Best regards, Allan J. Gold

Thank you for the comments! That gives me an idea to do a future article on what other edible flowers we can include in our gardens. As for recipes, I will leave that to the chefs of the world. Please post a good recipe for nasturtium if you develop or find one!

The only way I have seen nasturtium served is in a salad or as a cake decoration where the beauty of the delicate blossom can be enjoyed. The nasturtium in my garden do adorn my salads from time to time, but most are eaten on the spot as they are picked! You could consult some of the cooking websites for more creative uses. I am more of a gardener than cook (as my family will attest to!).

The title of the article really caught my interest. I followed some of the links to other articles on edible flowers, but nothing substantive was readily available, just more "teaser" info. I will seek out more info containing uses and recipes. However, if you have knowledge of other good sites, please share them in your article. Bon appetit!

when you talk about them being edible ,are thinking of them just being used for salad and as garnish on a plate, or are you thinking of some recipes ? If you do have some recipes, please share with readers.
