Glad to hear your husband is doing well after such a terrible accident. Lovely house.

Have you though about whether you need any large trees for shade for the front of the house or to “settle” the house into the landscape? I would start by looking at photos of country homes that have landscaping that appeals to you. I’m seeing a very relaxed, old fashioned garden that says “farmhouse”, rather than anything modern or like anything you’d see in a new development. You have an opportunity to create something really special here.

I don’t know if this style would appeal to you but i I had as much space as you have, I would be looking at Piet Oudolf’s garden designs for inspiration. It would be like living in a dream world.

Not all of them would suit your space, but some of his more meadow-like designs could be awesome as elements on part of your property. Piet designed many famous gardens all over the world. He’s written a number of books on his designs and on the plants he uses to create them.

Here’s a link.
Piet Oudolf Gardens

I like a meadow. A lot.

Prairie setting

Or if you like something more traditional. Farmhouse-y

Very simple low maintenance

I second the concept of a "relaxed, old fashioned garden that says “farmhouse” - yes with grass meadows. With 140 acres you will have plenty chores. There is no need to make the grounds around the house into another constant chore, unless one of you is an avid gardener, well then we can't stop you.

Some ideas to ponder:

A farm house landscape needs a legacy tree, that single, large, perfectly shaped, mature, deciduous tree. You have only shown us one view of the land. That tree might belong on a different side of the house. Someone has to plant that tree first. What is the state tree of Missouri? What is your favorite big tree? Give it the room to live to be hundreds of years old. Be the people who planted that tree.

Piet Oudolf is a great source for inspiration. His work is based on very intentional layout of plants. I think you could go with a more specific to your place, natural grassland meadow and still mimic Oudolf very well. A grass meadow is probably the best way to live with deer. Plenty forage and color for everybody.

Paths are most important in this kind of landscape to give it intention. Mowing would be easiest it seems and just done regularly with the areas kept as lawn.

You can add a touch of modern or formal

with sculpture placed in a meadow. Could even be done in plants. Picture this off in the distance from a primary view from the house, rising from the meadow, a row of columnar evergreens standing alone, closely planted to make a green wall or hedge shape with a single Lime Light kind hydrangea given the room to grow to its massive self when left alone.

First thing I would think about in laying out your landscape is the traffic patterns of people and the machines you will be using. If you do any regrading or bring in top soil think about grading the paths first and making them rideable in ATV's. That will help tell you where the gardens go.

There is joy to be found out there.

I can see there's slope near the entrance but can't tell details from the photograph provided. I suspect you may need to extend grade outward around the porch area. You'd need to show a transverse view, where the camera would be squarely in line with the porch and positioned over near the trampoline. A big part of the home landscaping is also going to be whatever foundation planting you do and the single photo (above) is not enough to see the subject. While you're near the trampoline, pan the camera while taking slightly overlapping photos that show the whole house with extra land at each, right and left, ends. (Don't move camera position between photos; just pivot. Don't substitute a computer generated panorama.) We should be seeing that view anyway since that's the side one would see when they finally arrive at the house.

The picture is a starting point to consider...

what a beautiful home! no suggestions from me, but I'm going to follow yours bc we are looking to achieve the same things as you it sounds like in many ways, and I got very little response

Thank you to everyone who responded! I've been out of town and couldn't properly respond from my phone. I'm on my computer now.

Saypoint - Thank you for being the first to comment! One of the things I've been trying to decide is whether to go for more "modern" landscaping or aim for traditional farmhouse-vibe, because I think our house is both. Your comments went right to that issue, which is wonderful. I love all the inspiration pics you attached, especially the one you labeled "more traditional" so I think I'm likely to go that direction. I just don't feel as happy when I look at pics I find when I search "modern landscaping." I'm eager to learn more about Piet Oudolf. Thank you for the recommendation!

Dig Doug's Designs - wow! thank you for the ideas. I showed this thread to my kids and they voted for your pic hands down. Very lovely.

Christopher C Nc - you give great advice. I especially love your comment about the legacy tree! We actually have one, an oak, on the east side of the house. We sited our house around it. Here are pics of the tree from our deck and a view of the house while standing under the tree. I think this is actually the prettier side of our house, but we're working on the south side first because that's what you see on the approach. And I agree, there is so much joy to be found!

Yardvaark - thank you for the advice about how to take the pics when asking for advice. Sorry I didn't include more pics initially. I appreciate the pic you put together. It really helps me to see how adding some plants and trees will really soften up the front of our house.
