We've got maybe 300 feet of graded slope that has been just a blank slate for a few years now. I'd love to cover it in azaleas or something, but the cost would be astronomical. I'm just guesstimating, but it has to be 9,000sf or more.

I am tempted to just plant monkey grass and some crepe myrtles and let it be. The cost to put down pine straw has been $1200, and I noticed the per bale price has gone up again.

Someone around the corner just landscaped a similar slope. They added stone wall accents, trees, azaleas, etc. Had to cost $25k for it, all in.

Anyone landscaped this much space without breaking the bank?

If you want to stay cheap just plant ground cover and some trees or bushes spaced out. I've seen some enormous azaleas is south LA, but they take years to get that big and I've never seen the large ones in full sun. Buy the right type of azaleas and space them out 12-18 ft apart. Plant them yourself and that's less than $1000 for one row of azaleas. If you're willing to spend more, you could plant two rows of Azaleas in a zig zag pattern. Jasmine ground cover would look beautiful to fill in the gaps, but it also takes time to grow and is somewhat expensive.

Is this slope mowable? If so, forget the pine straw. You will have to keep buying that every year. The trees/bushes you plant will be enough landscaping and you can mow the rest. Over time, the azaleas will get bigger and you will have to mow less.

A picture of this slope would be helpful

The slope is not mowable, I have to weed eat it and it is precarious.

I can take a photo but I tend to try to avoid doxxing myself here…

If you’re spending this much, just put in a retaining wall and have two levels of semi-level surfaces. $1200 of pine straw at $4/bail (last years price, now is $6/bail) is 300 bails of pine straw. Is that you spreading the pine straw or the guys driving thru the neighborhood telling you how many bails they laid down (they tend to tell you 1.5x plus number of bails actually used).

I would either let it go natural and weed eat or plant some creeping junipers or another plant that will spread. Maybe a clover or monkey grass or something as an alternative.

That's not what we are spending, I haven't even budgeted for this. We had some emergency work done a while back to fix a sinkhole, and (converse to what you might think) removed a ton of dirt and trees.

Plus side, our yard got bigger. Downside, this sloped area has to be maintained. Prior to this, it was wooded. There's no point in terracing this with a wall, it has significant height, it is easily 20 feet tall at the highest point.

We let it go au naturale for a bit, with some wildflowers and whatnot, but it ended up looking like shiat, and I have to weed eat the whole thing down. It's steep enough that it's not an easy task. Volunteer pine trees come up like crazy if we don't have a thick cover.

We have used the same guy for pinestraw for years, there's no monkey business. Price installed is probably more like $6.75 now, but I haven't even called him up yet.

Thanks for the suggestions.

When we lived in Georgia, we had a large wooded sloped backyard. I would blow and rake up all of the leaves and put out about 90 bales of pine straw. It looked good but was expensive and I dreaded the work every February.

Then I planted about 1000 monkey grass small pint sized plants at about $3 each. At first I still raked the leaves and added the pine straw but I realized that the pine straw was stunting the monkey grass. Then I just let the leaves cover the ground and monkey grass completely and the monkey grass took off and would still grow through the leaves. My work went to almost zero afterwards. Where the monkey grass grew to tall I would cut it down with my lawn mower and not bag or remove anything. Eventually the monkey grass spread together and did not get too tall and made a great maintenance free ground cover. It took maybe 6 or so years to fill in, but it still performed well before then to hold in the leaves.

You could hydroseed it with wildflower and ornamental grass seed

I'd plant it with native wildflowers. They will change with the season and never need to be mowed. Since you are not having to walk on it this is a perfect place to do this. Also it will be great for native bee's which we really need to look out for.

Depending on where you are, it may be worth getting a trailer or a uhaul and going to forest hill. Azaleas go for about 1/3rd retail prices so you could load up if that was a solid preference. Last I looked they were like $7 for a three gallon.

I agree with natives and just let it go.
