Improper palm Mulching
Mulch is a great way to help palms retain moisture and add color to the landscape, but too much of a good is well, bad. Improperly placed mulch can lead to trunk rot.
It can also cause improper root and palm development.
Do not allow mulch touch trunk
Do not allow mulch to build up more than 3 to 4 inches
Replace mulch twice a year removing old mulch and placing new mulch
Improper palm pruning
Palm trimming is required for some species that are not self-cleaning palms such as Christmas palms where the palm fronds fall off. Palms like Coconut or Date palms require trimming or the removing of dead fronds to be aesthetically pleasing.
The most common mistake made is over pruning of palm trees (Hurricane trimming palm trees) or pencil topping, this is detrimental to palms, this is also known making a palm tree hurricane ready, palm trees by nature are hurricane ready.
Over trimming cause the trunk to thin out over time making the palm weak in a hurricane or in hi winds causing it to break. Palms are not like trees palms take nutrients from the lower fronds when those nutrients are not available in the soil and translocate it to new growing fronds, this is why the lower fronds die. By removing lower fronds that are still alive you force the Palm to take it from the next lower healthy green frond creating a cycle and eventually the Palm will not have much to take from.
By allowing the lower fronds to remain until they are dead you allow the Palm to take up those nutrients.
Not sterilizing pruning equipment between palms can transmit a disease to palms.
Improper palm watering
Most palms I south Florida once established do not need frequent irrigation, avoid sprinkler heads to directly spray palm or trunks as this can course trunk rot. Nozzles next to palms or frequent irrigation to palms cause root rot that unless corrected and treated with a fungicide can lead to the death of the palm.
Improper palm fertilizing
Since most of the palms planted in Florida landscapes are not native but exotic meaning they are from another part of the world palms may not have any of the nutrients they need in our calcareous soils which tend to bind all the available nutrients to that sandy high ph soil because of the high calcium carbonate content in our limestone sediment layer.
Excessive use of nitrogen commonly found in lawn fertilizers such as 16-4-11 or 24-0-11 should not be used on palm trees as this can cause a nitrogen poisoning in palms neither should you use landscape fertilizers such as 6-6-6 which do not have complete or too low in micro nutrients like manganese, magnesium, iron, boron.
Improper plant placement around palms
Placing plants around the palm tree especially close to the root zone and trunk presents several problems, palm trees require Fertilizing at high rates to as much as 5 pounds of fertilizer per palm every 3 to 4 months which can cause damage to plants around it and or prevent palms from being fertilized properly.
Shrubs that grow up and around trunk can pose a lethal problem for palms by landscaper trimming equipment wounding the trunck causing damage to the bark which never will heal allowing or introducing a disease pathogen into the palm through the open wound.
Placing palm tree between two concrete paved or hard surfaces and placing rock around it increases temperatures killing or damaging new roots, the white rock makes it impossible to fertilizer palm without staining the rock.
