On January 23, 2014, Western Broward and Palm Beach Counties experienced temperatures in the upper 30s!\u00a0\u00a0 Certain palm species, particularly coconut palms, are not able to tolerate the cold temperatures well.\u00a0 The cold induces a severe manganese deficiency as the palm\u2019s canopy changes from green to mostly brown within a few weeks.\u00a0 The cold weather causes the palm to process its stored nutrition (the green in each frond) very rapidly.\u00a0 It is not unusual for over 50 per cent of the canopy to suddenly turn brown.\u00a0 If there is fruit on the palm, it will likely drop off suddenly as well.\u00a0 Palms use existing green fronds to generate new growth and when many fronds turn brown rapidly, a nutrient-deficient state is induced.\u00a0 Severe manganese deficiency is lethal to palms, and when left untreated the palm my die from lack of manganese.<\/p>\n
In addition, the cold temperature and the manganese deficiency cause tremendous stress on palms and present a breach for secondary problems such as insect and fungi that normally would not affect the palms.\u00a0 Beetles and other insects find stressed palms and lay eggs that hatch into larvae.\u00a0 The larvae, also know as borers, feed on the inside of the palm and can be fatal.\u00a0 There are several species of fungi that also attack stressed palms.<\/p>\n
\u00a0Proper treatment of your palms will give them their best chance for full recovery.\u00a0 Here is what needs to be done:<\/p>\n
The palms need to be treated with the proper fertilizer as soon as possible.\u00a0 Supplemental manganese should also be applied.\u00a0 Palms are very sensitive to the nutrient content of fertilizer applied.\u00a0 A fertilizer that is not specifically for palms can actually do more damage than good.<\/em><\/p>\n \u00a0A systemic fungicide and insecticide, both labeled as appropriate for palms, should be applied.\u00a0 This will protect the palms from insect pests and fungi that normally would not be present.<\/em><\/p>\n \u00a0It is very important not to remove any fronds.\u00a0 Palms need their green fronds to create new growth. \u00a0It is possible to kill an otherwise viable palm by over-pruning.<\/em><\/p>\n \u00a0In conclusion, palms that have been damaged by the cold need a little extra attention to facilitate recovery.\u00a0 Once the palm is recovering, proper maintenance fertilization will keep all your palms healthy and will provides a number of benefits, including a larger, denser canopy, increased cold hardiness and accelerated recovery from storm damage.<\/p>\n","protected":false},"excerpt":{"rendered":" On January 23, 2014, Western Broward and Palm Beach Counties experienced temperatures in the upper 30s!
