Lightning is a threat to tall palms. Symptoms are usually dramatic. Within a day or two all fronds noticeably droop and the foliage becomes a gray-green, later turning brown and eventually dying. Palms struck by lightning seldom recover. Even the shock of a nearby bolt can be a damaging setback.
Weeds always become a problem following the rains, and expect some to be pollen producers.
If you allow them to go to seed, expect more weeds in future years by a hundredfold. Hoe them out before they bloom, and preferably while they are young. Moisten the soil subsequent to the sweaty exercise, and they will come out easier. Weeds like purslane reroot easily if left lying on the moist ground, so put them in the garbage. Many of you want to use chemicals.
