Instead of pesticides, I’d like to try using a physical barrier or trap around the trunk of my apple tree to reduce Codling Moth. When/how should I do this and what are good materials to use?

Azaleas with yellow leaves #775710

Asked October 18, 2021, 1:45 PM EDT

Hello, I know that the problem is either the wrong pH or not enough iron. I'm waiting for my pH test kit to make sure that my pH is not too high as this can affect iron uptake. My question is can I give the azaleas iron this time of the year? Or, do I need to wait until March or April? If I can apply iron, at what rate? Regards, Gary Upchurch

Dying 30 Foot Tree #775707

Asked October 18, 2021, 1:36 PM EDT

Hello. I have a 30 foot magnolia tree that we just noticed has rapidly lost most of its leaves. It has never done this before. It has always appeared to be conjoined below ground with another tree, although the leaves on each one are different colors. One of them appears healthy. I have attached photos. I have many more photos but I was limited in this request to just 3.

Black knot resistant plum #775704

Asked October 18, 2021, 1:01 PM EDT

I was wondering if there is a black knot resistant ornamental plum tree. I am also looking for an ornamental cherry tree that is resistant to the fungal disease that causes the leaves to turn brown and drop early that so many of cherries seem to have in my area.

Mushrooms? #775703

Asked October 18, 2021, 1:00 PM EDT

Hi! We have some sort of mushroom/fungus that grows in our backyard under the grass. Our dog digs them out of the ground and eats them if we can't catch him. Do you have any idea what that might be? It's a white color and they just smell like a white mushroom you'd get from the grocery store.

Siberian Iris Dividing/Relocating #775701

Asked October 18, 2021, 12:46 PM EDT

Hi! I am dividing siberian iris to share with someone in North Carolina. They will not be able to be planted right away after digging them up. I know that this is a very hardy plant, but want to know if they should survive up to a week until they can be replanted if they are kept moist. Plan to put each clump into a plastic grocery bag. I appreciate your expert advice!

Canna Lilies on Septic Tank #775698

Asked October 18, 2021, 12:43 PM EDT

I have a few Canna Lilies planted on top of my septic tanks. They are new this year, were planted in the spring, and flourished. General advice seems to be to dig up the bulb once the plant starts to die (hasn't happened yet). However, I was told that because of the septic tank and corresponding heat that generates, that the bulbs could be left in the ground. What would you recommend? We live in Wright County.

Asked October 18, 2021, 12:39 PM EDT

I have forest land that was timbered a few years ago. There is now a low prickly plant that is growing in some areas that never existed before under the canopy. It is about the height of the ferns. It makes passage over the land very difficult. I would like to know what it is and the best options to remove it.
