Scott's Nature Scapes:


Hi everyone I'm Amanda with northern yards and gardens, and this evening I'm going to be working in my east facing flowerbed.

This is right outside the door that I use every day and night as I come and go from my house, so I just wanted to get cleaned up and looking a little bit better.

I'll show you what's going on with it.

So here's a look at the flowerbed from back far and as I come in closer I can point out some things to you.

So that's the door I go in and out all everyday.

So when I see this bed, it just doesn't really make me happy right now, even outside of the flower bed, I have weeds very large weeds I have sprayed some roundup on them I'm, but they're not dying very quickly and then I have new generational weeds growing already so I'm gonna do a little bit to take care of that and then, when I actually get into the flowerbed, you see a lot of green.

Most of that is weeds and all of my mulch that I had in here last year, I just use grass clippings.

As mulch um, that has like all degraded and like broken down so I have no mulch in here right now.

Nothing to keep these weeds down um, so I do need to get to the weeds, killed and then keep the next generation of weeds from coming.

I do have some very nice gold mouse pireas back there that you're, seeing and acclimated the clematis is already making a good goal of it.

Climbing that trellis I have some uh nice plants in here too, but you just can't even hardly pick them out from amongst the weeds, so I'm going to just get in here do some weeding do some spraying and some other things to make.

This just look a whole lot better and make me happier when I go in and out the door every day, so that I'm only left with small weeds that can be more easily sprayed and covered up.

My next step in this project is to suppress some of the future weeds and the way I'm gonna do, that is to use a pre-emergent herbicide.

So this right here is preen.

It's a product.

At a lot of, you probably recognize the name, you've been doing any gardening and it's a pre-emergent herbicide.

So that means it kills the weeds before the seed starts to grow, or it stops your seed from growing that way, whenever seed blows in on a windy day or if there's any seed, that's still in the bed that maybe gets stirred up for some reason, it won't grow so that way, I just have to get rid of the generation of weeds and they're currently, and then is a perennial weeds will still have to be taken care of, but this will stop those seeds from drawing from any annual weeds and the way I'm gonna put that on there you're just gonna use like this hand, spreader here and they're, pretty simple to use you just kind of have this hopper here where you fill with your products.

This one is adjustable like how much comes out at once and then a little hand crank here, and so that's how I'm gonna get my cream down quickly and over a large area.

This isn't very large, but I do have other parts, my garden that are really big.

So that's why I like to do something that fish, otherwise you could even grab like a handful and just sprinkle.

You can also buy preen in shaker bottle to have like little holes in them, and then you can just shake the product out.

So that's maybe a little bit more user friendly than like, but with this size of the gardens that I have I just go for the the largest possible.

So this right here, that's a 16 pound tub which I'm gonna be putting down, not all in this garden but out throughout the yard, and they would have suppressed all these other weeds from growing.

So it's too late now much to take care of these other weeds, a different way, but it'll stop the next generation of weeds.

The reason I waited, though, is because of this little guy right here.

This is a Morning, Glory, seedling and so Morning Glory vines are an annual, but they do sell seed very quickly very easily in a garden and I wanted to have a couple of lines.

This year, if I put down my preen before that plant had started to grow, it would have stopped any of my Morning Glory seeds from growing.

So I have one seedling right there and another one right here right there you can tell by the heart-shaped, leaves I think there might be just a couple more coming in other parts of the garden too, and that's going to be plenty because it only takes one or two plants to really cover this back wall.

Add a layer of mulch about two or three inches thick and that's not going to kill the weeds over there currently, but it is gonna, slow them down and then once they pop up above the level of the mulch, then that's what I'm gonna come in and spray them with.

Like a round I put down five bags of malts, there were two cubic feet each so ten cubic feet went into this bed and actually I'm a little kinds of left side and I need to do a little bit more because, if I pan to the right, this sort of starts coming around the corner into this next bed.

And you can see what a difference it is from where than my mulch is and chill where it ends, and so what I started doing this next bed, then I'll put down even more mulch, but just what a difference that makes it look so neat and clean now, and the plants really pop against this dark background.

Mulch hi, I'm gonna have to keep a close eye on this bed because, like I, said, there's a lot of weeds under there.

They're gonna come pop through this mulch, probably within the next week, and at that time, I'm gonna come out and I'm gonna spray them or pull them to keep this looking neat and clean all summer long.

So now that I have it to this point, I'll just be a lot easier to maintain.

Remember I have that preen under there that's gonna, kill the next generation of weeds and then I have the mulch to suppress the weeds and then I'm gonna keep an eye out for any of that come along, so I can get them sprayed before they get very large.

Thanks for joining me tonight on this quick redo of my front bed that I get to see every day as I come and go to work.

So now it's just a much nicer, looking cleaner bed that I have and it'll be easier for me to maintain.
