Cold Injury to Palms
Cold Injury to Palms
Mississippi State University Extension
To understand cold injury in palms and how best to protect these treasures in our landscape, we must understand how they grow. Unlike hardwood trees, palms have one central growing point, the point from which the fronds (leaves) grow. This part is called the palm heart or palm bud. Located at the top of the trunk, the palm heart is in an exposed location. The primary protectors of the palm heart are the fronds, which shield it from blowing objects, hot sun, and wind and cold. 

After a frost or cold injury, you may notice that the lower, older fronds are more damaged by cold than the younger, upper fronds. Regardless of how they appear, it is important to keep the fronds on as long as possible, at the least until there is no longer any green left in them and all chance of further cold is gone. Remember that the fronds also shelter the palm heart from direct sun, so retaining old fronds until new fronds have grown in is beneficial.

A number of weeks after the cold event, if you can pull the spear leaf (the newly emerging frond that is still tightly rolled and sticks up straight) from the top of the palm, then cold damage has injured it. The dead plant material and wounds caused by the cold may leave the plant open to secondary decay organisms that will soften the palm and may produce an offensive smell. The base of the spear leaf is especially sensitive to cold injury and secondary infection. Since copper-based fungicides are the only ones that can fend off both bacteria and fungi, the University of Florida recommends treatment with a copper fungicide drench to the palm heart area.

Care of Citrus Trees
Freeze damage symptoms and
recovery for citrus
Care of citrus trees that have been freeze-injured must be dependent on factors such as the time of year at which the freeze occurs, the condition of the trees at the time of injury, and weather conditions immediately following injury. These factors will influence the type of approach to use for the recovery of freeze-damaged trees. The natural reaction after a freeze is to do something right away, although there is very little that can be done at that time, as it is impossible to determine the full extent of the injury. Twigs and branches may continue to die for a period of several months to a couple of years following a severe freeze.

Pruning No attempt should be made to prune or even assess freeze damage until the new spring flush gets fully expanded and mature. Therefore, no pruning should be done until late in the spring or the summer after a freeze. This delay is desirable since it is difficult to determine the actual extent of freeze injury until new growth commences and fully develops. In early spring, freeze-damaged trees often produce new growth that soon dies back. Sufficient time should be given for the dying back to cease and for the new healthy growth to take place and fully expand. Experience has shown that early pruning does not promote recovery and that delaying pruning to the proper time will save money. Pruning cuts should be made into living wood and, where possible, at crotches, leaving no stubs or uneven surfaces. It is advisable to remove heavy brush from the grove immediately following the pruning operation.

Organic Fertilizers for Cold-damaged Plants
What can you do to help the cold-damaged plants in your garden? Apply Microlife Ocean Harvest or MicroLife 6.2.4 granular organic fertilizer to offer food your plant can take up as needed.

Do not apply synthetics that can further stress plants.

Medina Soil Activator, Superthrive, and Root & Grow are also recommended.

Succulents : Freeze damaged plants
Succulents and cacti have different tissue than woody or most perennial types. The thick pads and leaves store a great deal of water, as do the bodies and stems. Freezing causes massive cellular damage both inside and outside of the plant.
However, many of these plants are remarkably hardy. Don’t cut off the foliage or stems on damaged succulents. Instead, watch them for a period of weeks. Pull gently on interior leaves to see if the core is damaged on plants like aloe and agave.
If interior leaves pull out easily and are mushy and black at the base, the plant has succumbed and should be removed. If you see signs of new leaves and growth, the plant is salvageable.
