Hunker may earn compensation through affiliate links in this story. Since this photo was taken, the owner sold the palm and had it moved . Whether the palm is an inground or container plant, gently shake soil from its roots, and separate its root ball, identifying attachment points for each stem. Palms stressed by cold temperatures are very susceptible to secondary bud rot (Figure 5) and may later show signs of micronutrient deficiencies, such as Mn, due to lower root activity at cooler temperatures (Figure 6). Water stress occurs when water is limited or the root system is incapable of taking up sufficient water. Acanthophoenix crinita trunk and leaves Acrocomia aculeata trunk Astrocaryum standleyanum trunk. Always plant large palms such that the top of the root ball is about even with the soil line. 1968.

Electromagnetic fields within 5 feet of a high voltage power line appear to cause injury to palm foliage. Luckily the cracks don't face out so you only see them if you look around to the palm's backsides. If you overwater, the palm fronds can easily turn yellow or brown. Examples of clustering palms include the areca palm (Dypsis lutescens), everglades palm (Acoelorraphe wrightii), Senegal date palm (Phoenix reclinata), and Formosa palm (Arenga engleri). Boron toxicity is rare in areas that have high rainfall, but can occur in drier climates (e.g., central California). Deep planting is easily diagnosed by symptoms plus digging down into the soil to determine the depth of the root ball. Drill a 6-inch hole below the crotchs top, and be sure to attach large washers at the two ends of the bolt. If the branch is in good condition, you can reattach it to the tree.
