Symptom Diagnosis For Common Palm Tree Problems

Using visible symptoms to diagnose palm tree problems you see is not always reliable. Multiple possibilities cause similar symptoms. Yet it's the quickest, cheapest way to try figuring out a common problem.

Look at the first symptom. See which palm species typically have that problem. Getting help from Palm Books is quite helpful.

Common Palm Tree Pests & Palm Disease Problems

Nothing throws a skip into your palmy heart like finding that first symptom on your palm tree. Teeny bugs crawling around, or leaf spots with different coloring. Or something oozing out from a palm trunk. Reminding you of some horror end-of-the-world film!

Let's see the wide range of diseases & insect attacks that are common palm tree problems.

Common Tiny Insect Palm Tree Pests Signs & Symptoms

These pests damage palms in various ways.

  • They chew into fronds.
  • They feed on palm sap.
  • And Tunnel into essential Palm Parts.
  • They carry palm disease that causes bacterial infection.

How Tiny Insect Pests Harm the Health of Palm Trees

Two Scientific classes attack palms. As arthropods, Insecta & Acari have exoskeletons made of chitin.

  • Scales: Tiny squooshy bugs that cover themselves in dull color disguises. Three scale insect species harm palm species by sucking out sap juices.
  1. One attacks landscape palms: Eucalymnatus tessellatus. The main problem is leaving behind honeydew waste secretions.

  • Mealybugs - Very small, with oblong shape. And a white waxy covering with wax projections all over. Usually found hidden near leaf bases & other unnoticeable spots. They choose a feeding place & stay for life.
  1. Problematic is sooty mold growth encouraged by mealybugs' abundant honeydew excrement.
  2. A natural predator is the Mealybug Destroyer, a ladybird beetle.

  • Weevils - Small snout beetles. Along with other palm weevils, often the prime targets are stressed palms. Their harmful stage is larval, drilling holes, tunneling throughout the lower trunk.
  1. The Red Palm Weevil or Palmetto Weevil is native to Florida. They can be solid black to almost all red, with patterns. In recent years it's become more widespread. Attacking Canary Island Date Palms (Phoenix canariensis), Bismarck (Bismarckia nobilis) & Latania species of palms. AKA Palmetto Weevil. As 
  2. One species carries nematodes that cause red ring disease. Attacking Date & Royal Palms, but primarily Coconut & Oil Palms. It's a deadly disease.
  3. The red ring is internal. Outer signs are misshapen fronds yellowing then turning reddish-brown. Then wilting & dying.

  • Nematodes - Wormy looking parasites, in the scientific Phylum Nematoda. Most commonly carried by Palm Weevils, especially Rhynchophorus palmarum.

  • Thrips - Teeniest narrow winged pest. Nymphs & adults do the damage. Roughing up frond undersides to feed on cell innards.
  1. Symptomatic fronds look silver, with tiny scatted black spots.

  • Spider Mites - Another tiny insect that sucks out palm sap. White webbing hints that they're attacking. Injured fronds have scattered spots. Primarily a problem for Potted Palm Plants. Inspect indoor palms regularly & prevent with regular Rinsing With a Syringe.

Common Palm Tree Disease Problems - Signs & Symptoms

Palm Tree Landscape Problems With Freezing Weather

With Hard Freezes, there's the danger of bacteria or fungal disease attacking the weakened apical meristem. Commonly, Lethal Bud Rot. Use copper fungicides asap, then again in a week.

Different Types Of Fungal Disease Palm Tree Problems

Multiple species can be affected by a fungal illness. Palm Tree Fungus Spray is a treatment.

  • Root & Pink Rot - Fungal disease attacks numerous Palm Tree Parts. Often Container Palms without good drainage and/or from Overwatering Palms. Tons of pink fungal spores are symptoms. Causing discoloring.

Allowing No Soil Drainage, Giving Rise to Rot Fungus
  • Trunk Rot - Two pathogen species cause fatal disease in landscape palms. Fungal spores can contaminate nearby palms. An infected tree becomes a hazard & needs removal.
  • The fungus Ganoderma zonatum causes Ganoderma Butt Rot. Typically in the Southeastern U.S.
  1. Oldest leaves dying early is a first symptom. Along with white bumps (conks) on the trunk bottom. They enlarge & turn brownish. Brown tips on fronds throughout the infected tree, wilting follows.
  2. "Guts" in the lower trunk degrade, leading to the palm falling over.
  • Thielaviopsis paradoxa attacks mature palms worldwide. Fungal spores invade from a wound or cut in the upper palm trunk (think unnecessary pruning!).
  1. Inner tissues spoil, causing trunk weakness. Meanwhile fronds die progressively, beginning with leaf tips.
  2. Sometimes, brown ooze leakage is seen. Eventually the palm bends at the upper trunk, under the crown. Then breaks off.

Other Common Diseases That Are Palm Tree Problems

  • Leaf Spots - Multiple species cause these palm tree problems. Watch for yellow (chlorotic) areas. Then turning brown & developing a dark ring around the edge.

  • Blights - Affect Specific Parts of Fronds, especially the rachis or petiole. Normally not deadly, but doesn't look very nice! Because blight turns leaflets, segments & stems brownish.

  • Fusarium Wilt - Block water flow within a palm. A fatal disease, as you can imagine. Primarily attacking the Queen Palm, Mexican Fan Palm & also Canary Island Date Palms.
  1. Usually begins with lower leaves. Turning yellow (chlorotic) & dying.
  2. It moves upward, gradually killing all fronds.
  3. Distinctively on feather fronds, because it begins on one side of the stem (rachis).
  • Phytoplasma Disease - Problematic bacteria. Carried mostly by Hemiptera insects: leafhoppers, planthoppers or psyllids.
  1. Primarily causes Phytophthora Bud Rot. The spear & new growth fronds affected first. With wilting & discoloration. Affects about 30 species, but especially Coconut Palms.
  2. In the Southeastern US & Caribbean causes Lethal Bronzing Disease. First symptom is early drop of the fruiting body, or flower stalk rotting. Preventative antibiotics may obstruct spread to healthy palms.

Nutritional Palm Tree Problems That Harm Your Plant

When growing palms recognizing nutritional problems is important. But better to have needed information to prevent these problems!

For instance, lack of the right nitrogen percentage in fertilizer can cause yellowing leaves or excessive growth. A lack of potassium can cause leaf tips to die.

Also deficiencies in magnesium & manganese can lead to palm fronds losing their green color. Often turning yellow (chlorosis).

The essential basic is knowing your palm soil's pH. With alkaline soils, needed elements won't be absorbed. That's why A Soil Test is the starting point.

Sylvester Palm Trees common annoying Problems

Phoenix sylvestris is a nice durable palm. So what could be wrong? False smut symptoms can occur. Teeny, tiny black, brown or yellow spots on frond surfaces. That become leaf indentations.

  • Yes, False Smut Disease is possible! Yikes, what is that? A kind of fungus most often harming Phoenix palms in humid areas. Yet not usually deadly - just doesn't look pretty.
  1. There's skimpy management & containment research. Trying Fungicide is fine. Follow product directions. Catch it early, then treat by trimming off affected fronds.
  • Beware of spiny spikes on the leaflets!
