Planting Cherry Trees

I live in St Mary's county. I want to plant a couple sour cherry trees. I have been given two recommendations, Montmorency and Dwarf North Star. Do you agree with those recommendations or do you have a better recommendation. I'm looking for something easy to grow. I have very little experience with fruit trees. I have mostly clay soil. What would I need to do to the soil to give the cherry tree's a good chance of surviving and thriving? Finally, do you know of any nursery's in Maryland that sell these tree's? Thank you and have a wonderful Thanksgiving.

How Big

How tall do arborvitaes grow? How big around? I have two that have been growing for about 20 years. I prune them every 3-4 years but they now are 10 - 20 feet tall and about 4 feet in diameter. How much taller will they get? How much larger in diameter?

Rodents or What?

Hi, I am a resident of Montgomery County and have noticed a fairly significant hole not of my doing that is adjacent to the foundation wall of my house. I called Washington Gas (someone suggested that gas lines could result in a sinkhole) but they the hole said \was not due to the gas lines. I then feared that it could it be (or have been) rodents and that is what directed me to the UMD Extension Services. Attached are a few photos. I dumped a bag of rocks (which can be seen in one of the photos) and was surprised to see how little it filled the hole. I then measured the length of the hole and it was about 3 feet. Can you advise on a possible cause and plan of action to fill it. Is this something I as a homeowner can do (more rocks?) or do I need a contractor? If the latter, what kind of contractor does this type of work? Thanks.

Fig Tree Wintering

We planted a fig tree, Chicago Hardy, 2 years ago. It is doing well. It is around 3 feet high and wide. We are wondering what we need to do to have it survive a cold winter. It has been recommended that we encase it in leaves, so we put our ground up leaves around the tree just before the first frost, intending to remove the dried leaves in the spring and use them for compost. However, others have suggested this might not be good for the tree because it might lead to mold and insect damage. What do you think? Will this be harmful? Is there a better way to protect the tree from a long cold spell?

Knock out rose pruning

I have a knock out rose bush that has done amazingly well, but it's getting much bigger than I anticipated and I'm wondering if, when, and how I should prune it back, beyond the normal trim back (about 25%) I do in very early spring.

pruning back

I'm never sure whether my plants are best pruned back in late fall/early winter after the first frost, or late winter/early spring before everything starts growing/blooming again. In particular, I have a couple of shrubs (butterfly bush and St. Johns Wort) that are prolific and tend to get leggy, some vines like clematis and honeysuckle, a couple of ornamental grasses, and a bunch of perennial flowers. Can you give me some guidance?
