They are particulary comon where a palm is grown in a more spartan environment, i.e., one in which the palm has limited access to resources, particularly where a palm is kept in a pot long after it should have been planted in the ground.

Fertilize all palms separately from the lawn. Iron deficiency in palms is usually induced in palms growing on poorly aerated soils (compacted or over-watered) or in palms planted too deeply. Research has shown that cold hardiness in Cocos nucifera in the landscape or field nursery is enhanced by proper fertilization (see Fertilization of Field-grown and Landscape Palms in Florida). Outer trunk tissues may seem solid, but affected palms have a hollow sound when tapped. Potassium tends to leach rapidly from sandy soils, and it is in these soils that potassium deficiency is more apt to occur. If the leaflets are not green, that is an indication of a nutrient deficiency. Washingtonia robusta and Syagrus romanzoffiana appear to be the most susceptible species to trunk snapping or crown toppling. There is no point in treating root rot disease without first correcting the primary reason for root suffocation. If the phosphorus is lower, it helps the palm trees use their nutrients efficiently. Warm subtropical, with occasional frosts. Palms in general are fairly tolerant of drought once established in the landscape. 1981. Dig down to determine if the palm was planted too deeply.

More information on how to grow outdoor palms successfully is provided in HGIC 1019, Palms & Cycads. Nutrient deficiencies can be caused by insufficient nutrients in the soil, a nutrient imbalance, poor soil aeration, a high soil pH, and an excessive planting depth. I plan on growing some dense plants around the bottom, and maybe attaching some epiphytes further up. Palms are sensitive to nutritional deficiencies, and frond removal can worsen existing problems and weaken the tree. 1968. Grow only palms that are adapted to your climate. You can wrap the damaged area of the bark with a light-colored tree wrap to accelerate the healing. Sunburn can affect most species of palms.

Palms in poorly-drained landscape or field sites, or in poorly-drained container substrates often suffer from this problem. 2010. Msg frequency varies. Use a sharp knife or shears to cut downward between the stems, dividing the clump but preserving major roots feeding each stem and keeping as many small roots intact as possible. Apply Epsom salts at 2 to 4 pounds per tree during the in-between months of regular fertilization. Cocos nucifera, Phoenix dactylifera., Hyophorbe spp., Thrinax spp., Coccothrinax spp., Allagoptera arenaria, and Serenoa repens are highly tolerant of high soil soluble salts. Cutting those roots free from the main root ball requires the use of shears or a. 360:181-188. Most are about 6 inches long and 1/2 to 3/4 inch wide. On some feather palm species, you will occasionally observe long, narrow strips of green tissue hanging down like long shoe strings from the leaves (Figure 12).

Contrary to popular belief, clustering fishtail palm (Caryota mitis) stems all die within a period of a year or two after flowering. As the root initiation zone on older palms expands up above the soil line, these new root initials, which arise from tissue under the "bark" (cortex) of the palm trunk, eventually force the "bark" outward in a flared fashion (Figure 3). If you overwater, the palm fronds can easily turn yellow or brown. In landscape situations, preemergent herbicide toxicity arises when materials are applied at rates higher than specified on the label or if they are applied too frequently.
