Q. Whte Powder On Palms And Other Trees

I just bought a house with a beautiful garden, but neglected. I see the palm fronds and some other trees have what looks like dry, white powdery areas on the leaves. The camellias have gray or black spots and the leaves are discolored. The garden has been abandoned for several months. I’d love to make it beautiful again!

This is powdery mildew. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/problems/get-the-cure-for-powdery-mildew.htm

You can also try using neem oil to treat the plants.

Q. Grub Worms

I am in Mexico and having a awful time with grub worms in my plant beds and palm trees. What would you recommend to use in these areas?

A child and a bucket, works wonders. Do not use any of the commercial poisons for grub worms, since it will also kill off all your grass, plants, and more than likely any trees that you have growing in that area. The poison can last up to five years, leaving you with an area that if virtually empty, and useless as far as planting anything there.

Q. protecting cold hardy palms

I have several windmill, European fan and needle palms, all of which are rated cold hardy and are in pots. We have been hit by unusually severe cold weather (10-15 F), so my question is, will it do more damage to bring them indoors to a 60-65 degree environment or should I just wrap and cover, leaving them outside?

It sounds like they are in containers, so I am providing advice based on that.

The windmill and needle palms should be fine outside. I would recommend finding a sheltered location for them outdoors or wrapping them in burlap, just to keep them from possible windburn damage.

The European Fan palm's hardiness though falls right at the edge of your zone, and because it is in a container, that actually moves it out of being hardy in your zone. So I would recommend either moving it to an attached but unheated part of your home, like a garage or basement, or just bringing it indoors.

Q. Bent over top of indoor palm

I have had an indoor palm for 25 years, and the top has bent over. About two feet of the tree is bent over and weak. What can I do to help it? I have moved it for more light and fertilized. It was repotted about a year ago.  The top looks healthy except the fronds are small.  I have tried bracing the top and now the lower fronds have bent where they meet the trunk of the tree. It’s looking very sad.

Does the top look "frazzled"? I suspect that your plant may be suffering from a condition called frizzle top. It is cause by a manganese deficiency. Here is more information:

Q. Transplanting Palm Trees

I have transplanted 4 palm trees. They are about 4 ft. tall. I live in the Palm Springs, CA area. The trees looked fine for about a week or so. They all look like they are dead or dying now. I have watered them extensivley since transplanting them. What can I do to help them survive? I also wanted to know about citrus trees. I have purchased 5 trees and transplanted one tree. They seem to be doing okay, but I was wondering if I should be fertilizing (and what type) them now.

It sounds like the palm tree may be in transplant shock. This article will help: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm As for the citrus, since they are newly transplanted, I would recommend using a fertilizer that is higher in phosphorous. This will help them grow strong roots and get established better. Fertilize at half strength though, so that the fertilizer does not burn the roots while they are adjusting.

Q. Palm Trees

All the leaves have fell off the palm trees (6 to be precise – 3 have begun to wither at the top of the trunk that’s left). Will they grow back or should we cut them down? If so, to what level? The winter just gone has had a devastating effect on them? Is this what has caused them to shed all their leaves or is it something else?

If you had a colder than normal winter, then yes, the cold did this to them. Most palms do regrow their fronds, but not all palms do. If you let us know what kind of palm you have, we can let you know if it a kind that does regrow and where it will regrow at.
