powdery mildew on asters and bee balm

I started gardening in Rapid City 2 years ago. My asters and bee balm developed powdery mildew last summer, worse on the asters. A picture is below. I probably didn't remove enough of the diseased plants last fall. The asters already have small amounts of powdery mildew on the leaves now in early spring. I tried spraying with milk and water last summer, but not sure it helped. I am considering trying sulfur. Is there a safe fungicide that you would recommend? Thanks.

Flowering vine for hot area, red clay soil

The previous owners of our house put up a large post and lattice structure on our hot dry hillside -- maybe to grow grapes? We don't know. It's probably 6' high and 12' wide. We refer to it as the giraffe hitching post, because it has a high rail you could tie your giraffe to. If you had one. I can get water to that spot, and would like to plant something - maybe a vine with flowers. Red clay soil and gets A LOT of sun. Hillside faces west. Any suggestions welcome!

Lime for my lawn

General recommendations tell us to put lime in our lawn if I have a dog. I live in the Black Hills, on a mountain of limestone. Should I lime my yard, it sounds like pellets work better to apply, and take 2 years to work into the ground. Also, instructions say it's not good for dogs, my dog is outside a lot.

Pruning Cotoneaster

I have several bushes of cotoneaster. They need pruning (too tall). Can I still prune them now? They appear to be putting on buds. Also, should I cut all of the fire blight branches out of the plant, or just prune them?

Local Plant Recommendations?A

My husband and I recently relocated to Rapid City and have no idea what to plant. We are looking for some recommendations and any help is appreciated. We moved from Oregon and LOVE berries, but we don't know if berries do well in the black hills. Thank you for connecting us with a master gardener or giving us some tips. Our front yard is directly north facing and our back yard is south facing with most of it receiving full sun. The eastern area is down hill and can/does receive much runoff. We prefer to connect with a gardener who could assist in our selection of native plants.

I had a question this morning from a person who has a Cortland apple tree on his property. He said when he first picks the apples they are crisp and tasty but after a few days they turn mealy. He is wondering why this is happening.
