The red palm weevil, Rhynchophorus ferrugineus, is a species of snout Beetle also known as the Asian palm weevil or sago palm weevil. The adult beetles are relatively large, ranging between two and five centimeters long, and are usually a rusty red colour - but many colour variants exist and have often been misidentified as different species (e.g., Rhynchophorus vulneratus; ). Weevil larvae can excavate holes in the trunk of a palm tree up to a metre long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm

Usually once every year or two, Sago Palms bottom frond will die off in order to produce new ones that shoot out the top. Once they die you can pull them out with your hand because the fibers that attach them are also dead.

check you soil ph sometimes the soil Ph can change. and can cause this. also try some plant food in water. out side plants sometimes need some food over the cold months. also if it gets to cold for to long it can kill the plant off.

Yes you can, just don't pull them out of the ground, dig around them and deep enough to keep most of the roots intact. Dig the holes where you want to replant them first before digging the yuccas out!!! Once you have your plant dug out replant it in the new hole as soon as possible, use some good potting soil to fill around it and water it.. Yuccas are very tough plants so you should be OK.

Hello Eileen, W/D here.
Palms will reabsorb some of their nutrients when fronds are shed, even over winter. If possible, you should let the ugly fronds go, and allow the trunk to take back what's stored in the frond stems. When they become brown, or less green, or droop, they can be pruned. This is usually found with the lower fronds. If upper fronds exhibit these symptoms, it is usually from the effects of winter, but the same rules apply, except that you can trim partial fronds to get rid of the brown leaves.
The acid test for a palm is, if there are shoots in the middle of the canopy protruding, to pull on them firmly, but not aggressively. If the shoots pull out easily, the palm is probably dead. Some winters are more brutal than others, and palms take the worst of them. We double-cover our palms, and place lights inside of the covering that we make, and the larger ones have made it over winter now for about 5 years. I have used incandescent Christmas lights wrapped around the trunk and hung in the canopies, then covered and it worked well too. One friend slaved his Christmas lights to his pool pump control panel, only to lose his palms. Seems that he was using LED lights, which put out no heat. Queen palms have died in droves this, and last year, as have unprotected Robellinis. Washingtonians and Pindos have fared better. If you live in a coastal zone, you still need to cover and keep your palms warm through the worst of winter. We have used fitted sheets on the smaller canopies to contain the fronds, then covered that with plastic tarps, weighted down on the sides to form a mini greenhouse, and it works pretty well, but it's inconvenient. With spring here, there will be a lot of new outdoor umbrellas purchased, and the old ones will be pitched. We already have picked one up from a neighbor, and will erect it over one of the palms, then cover it as described. The thinking here that it should be much easier (and quicker) to protect the palms via this method.
As for the fungus noted, try light applications of a fungicide, but check first with a local nurseryman to see what works best in your area.
Hope that this is of some help.
Best regards, (and please rate this solution), --W/D--
