I want to plant hostas around a tree, but when I start digging there are so many
I'm assuming there are to many tree roots? You might want to consider planting them in containers and putting them around your tree. Or you can add a raised bed type arrangement that can be filled with soil so your tree roots are not affected, but you have enough soil to add your hostas.
I have recently found groupings of very small blackish either bugs or eggs on the leaves and/or in the lower curl of the leaves as the leaves come out of the ground. Also, the flower portion that was just coming up is covered in them. I have cut the affected pieces off the plants. What are these and how do I get rid of them? Please help. I live in Calgary, Alberta, Canada.
My first thought was that was you are seeing is slug poo. Have you seen any there? Slugs love hostas and there are various treatments for them. Here is a good link.
I understand and believe I have identified the cause to the browning of my hosta leaves. I didn't know if I should cut them. It seems they would be susceptible to pathogens. Any words of advice?
If they are fully brown, then they are dead and it is safe to remove them from the plant.
I have many (50+) hostas and the deer have eaten more than half down to the ground. I would like some ideas on how to keep them out of my yard. I live on a one acre lot on a golf course, and the deer are not afraid of anything or anyone. Any help would be appreciated.

After the small purple flower falls off of the tall stalks that grow from within the hosta, should I cut them down? What purpose is that stalk?
Yes, you can cut the stalk--other than holding the blooms, it really has no purpose. Many people actually cut the stalks prior to flowering to allow more energy to go into the foliage growth.
How do I divide a hosta plant?
You can normally divide these plants anytime from spring through fall. Simply dig up the clumps you want to divide and split them with a spade shovel, getting anywhere from 2-4 (or more) smaller clumps, depending on the overall size. Make sure each new clump has some roots with it and replant elsewhere. This article should help you as well: https://www.gardeningknowhow.com/garden-how-to/propagation/propgen/dividing-plants.htm
I live in Arkansas and have a variety of plants in pots on a covered patio with morning sun. Most obviously affected is the hosta. Due to the extreme heat, I water every day and the pot is plenty big. The leaves fade yellow and then dry from the tip in a very slow process.
This is indicating that they are still not getting enough water. Even though they are in a big pot, in high heat, they need to be watered 2 times a day, due to the fact that water will evaporate very quickly (especially if they are clay pots).
You also need to make sure that the soil is thoroughly wet, especially if it has been allowed to dry out completely. Soiless potting mix can actually repel water if the mix is allowed to dry out and needs to be submerged in water for a few minutes to rehydrate it.
