With a new batch of hostas just planted, I had a neighbor tell me "if I put blood meal on the flowerbed it would keep the rabbits away." After I read your info, it didn't state rabbits. How often and when/where is the best way to apply the blood meal? How long does it last and is it still effective after it rains? The rabbits did not just devour my garden after the new growth was looking great, they enjoyed the feast of roses and any new bud, lilies and their new buds, hosta leaves, marigolds, tulips and their leaves, and any new young flowering or green plant I've tried to plant this year. I did get the container of urine from menards this spring which worked great and I didn't see rabbits for about 5 days but I finished that after I planted the hostas last week. But what else can I do?
Blood Meal can work against Rabbits also.

Something is eating holes in a lot of plants around our yard. Hostas, lilies, peppers, even rhubarb are getting devoured. I wondered about slugs but it has been very dry here, so I wouldn't expect there would be THAT many slugs out at night. There are a lot of small butterflies around, and a lot of webs. Could these all be related??
Don't be fooled, those slugs can be out there!
This is the time of year where are gardens are under attack by lots of insects.
I would address the possible slugs but also use Neem Oil as a treatment. It works as both an insecticide and fungicide and won't harm bees.

Our hosta leaves have all turned brown and look like they are rotting away. Is this the black weevil? Is it crown rot? What can we do? We have had very little rain and our summer has been very hot. Could it be that they are just dry?
It may have crown rot. Here is more information on this: https://www.extension.iastate.edu/publications/sul8.pdf
Should I cut back the spent flower stalks of the hostas at my new home?
If you do not like the flowers, yes you can cut them down when they appear.
After they are done blooming you also can cut the spent flowers down.

Some of my hosta leaves are turning tan to yellow in blotchy patches. I have cut those off and bagged them. What can I do to treat this?
Here is an extension article that discusses spots on hosta leaves.

Based on your description, it sounds like maybe you have sunscald? If so, then this article will help you:

Happy gardening!
My hostas have been in place for many years. Until recently, the ones with green leaves and white stripes were looking great and producing blooms. Then they began to experience a yellowing of the outer leaves. Now many of the leaves have yellow and surrounded by leaves that are a light brown. The summer has been relatively dry; a few inches down the soil often appears dry. Recently, we have been experiencing hot weather. When I have watered them, the leaves closest to the main body of the plant and the flower stems stand up looking straight and tall. What can I do to prevent this from happening? This also happened last year to the ones that have the out white stripe. The ones that no stripe appear to not have this problem but are in a different location and receive afternoon soon.
Yellowing leaves generally indicate watering issues. It does sound like they need more water.
I would trim up the plants and give them some water to help sustain them through the hot summer days.

Something has eaten holes along the center of every stem on some of my hosta plants. Never saw that before, and I have had hostas for over 20 years, and have about 200 plants. The plants affected are only in the front yard. I know slugs and snails can be a problem eating holes in leaves, which I treat with Sluggo or Bug Etta.
Difficult to identify the culprit, but late summer can bring a host of pest issues to the garden.
Gardening is aways keeping us on our toes!
I would treat with Neem Oil and do so weekly as a preventative throughout the remainder of the growing season.
