I have a skunk that has dug under the foundation of my front porch. What is the best way to get rid of it? It just appeared overnight, so I hope it has not had babies yet. This has been a recurring problem over the past 10 years or so.

I performed a soil test, and the results from MSU indicate a Potassium deficiency (92 ppm). I am going to convert this area of the yard into a flower bed with shrubs and perennials. I also want to plant more trees. Can you make any recommendations for fixing my potassium deficient soil? I assume that I should make soil improvements prior to installing my new beds...

What tree is this? I'm thinking pignut hickory, but I’m only familiar with Shagbarks. I've not seen hickories in the general area at all. As you can see in the picture the bark is heavy, deep, and impressively criss-crossed - on the side that hadn't lost the bark. That’s a grocery bag in the pic to help with size. There are only two trees with this bark in the entire area. The fallen one (all but one root rotted) was about 100' tall and had a 22" diameter trunk. The trunks on both trees are impressively straight with no branches until over half way up the tree.i cut dead trees for the farmer, and he says this one burns very well. The split pieces show the heart wood to have a good looking reddish hue. When splitting there always seems to be "stringy" pieces attached between pieces that break or pull apart fairly easily. The center seemed to be an inch or so of darkish wood that almost separates from the rest. Striking the center 3 inches was softer (mushier) than further out. It rarely cracked at all if I hit dead center. The rings seem hard to count - see pics. Im guessing the tree is 200 years, but you can probably tell from the pic. I remember the leaves from last year when the tree had fallen. They were shaped like an elm or beach. However, I don't remember if they were toothed or not. They weren’t glossy or deeply toothed. It seems there were at least 5 leaves on the "leaf" - maybe 2 sets of opposite and 1 at the end, but my memory isn't...Sorry. I do have some twigs from the downed tree. They are round. The ones that give the most detail however, may be from another tree's branch. If from the same tree, they would have opposite leaves at the base of the "leaf".

My garden space has become too shady and is not useful for growing vegetables. My plan is to convert a portion of my back yard that does not have any shade issues into garden space. The issue is I need to kill the grass and then till it. I have read of some health implications of using Roundup particularily on a space for growing things to eat. So, the question is; how do I safely kill the grass to create the garden space for approximately 20' x 80'?

Are FireMaster Black Gums more tolerant of alkaline soils than Nyssa Sylvatica in general?

One nursery website lists the pH needs of the Fire Master as 4 to 8. Will the Fire Master truly tolerate soil with a pH of 8? I see that Black Gums generally require lower pH, not alkaline. My soil is alkaline and I am hoping that this particular black gum, the Fire Master, will tolerate my alkaline soil. Can I safely plant it? If so, can you also please tell me if this tree is too dense to easily grow a ground cover beneath it?
