Girdled Apple trees

The rabbits girdled 100% circumference of all my 2 year Apple trees about a foot above ground. Is there any grafting of any kind that can be done to save them? A couple of websites said you can cut young trees off at 45% angle and they will regrow and train one to be main.

Any advice beyond wrapping better??

Honeycrisp leaf mottling

Hi- I have 5 Honeycrisp trees. All planted in the same area. All are about 6 years old. One is vibrant and has produced a good crop for the last two years. The other four all show leaf mottling and are not really growing well. The four stragglers have trunks about that are two inches in diameter and the healthy one has about a 4 inch diameter trunk. The four start out with new leaf growth looking good and then mottle throughout the season. I also have 5 Zestars that are three years old, planted in the same area, are very healthy and four of them produced last year. I have not tested the soil. The UMinnesota did not have any real answers when I sent leaves in to them to review, more water and nitrogen. How do I know if they are in need of calcium or other nutrients other than the normal 10-10-10 for example. Thanks

White 'Things' on Indoor Plants

I have been getting these white 'things' on my indoor plants. Is this a fungus or a pest? Any recommendations on getting rid of these as it appears to be spreading to other plants in the house?

pods on honey locust trees

I have 2 honey locust trees that produce large pods that fall early winter through early spring (female?, thornless). I also have one tree that bears no pods (male?). Is there a way to stop seed pod production to these trees?

I've heard to spray the entire tree with Ortho Sevin during budding time. Don't want to do this due to very tall (maybe 45-55 ft )and possible harmful drift. Maybe a heavy concentration of Sevin/H20 watering to the tree's base during the spring sap run?--the 2 female trees, not the male? Or any other ideas? Thx.

Planting a bur oak I started

I picked up these acorns at Sullies Hill at Fort Totten. I have noticed we do not have oak trees on our property which is only miles away, along the lake. Unfortunately I had not read your answer to the fellow from Cass County till today. I have started these acorns in regular potting soil. Will i have trouble replanting them this fall? I also will have to repot to larger pots, should our soil be used to repot?

Bark problem on the base of a Hot Wing Maple tree

The bark at the base of my 3 year old Hot Wing Maple has vertical brakes. In one place the bark has pulled back and caused an opening that is 3 x 2 inches. See attached photograph.

I have mushrooms growing in my back yard. I'm not sure how to identify them but I would like to know if they are poisonous or maybe even edible. We have dogs so I definitely would like to know if they are dangerous.

The first two pictures are of the same mushroom. One was taken while the mushroom was still in the ground and the other is after I dug it up so you can see the underside.
