What's up world? Welcome back to another episode of Just Grow at the podcast.
0:11
I'm your host, Big City Gardner. And today we're talking cover crops.
0:16
Let's get to it. Are you looking for a way to improve your soil quality,
0:21
improve the nutrients in your soil,
0:23
improve the water retention of your soil all while making sure that the soil microorganisms are happy and thriving.
0:31
Well, if you're looking to do that, then look no further than cover crops.
0:36
So what are cover crops? Cover crops are completely different than any other type of crops.
0:42
Other crops are either cash crops or crops that you grow with the intention of eating.
0:48
That is not what cover crops are. Cover crops are grown for the health and benefit of our soil.
0:55
Cover crops are something that we plant in our garden to make sure that we do not have any bare soil.
1:01
Because if you leave soil, bare and exposed to the elements,
1:05
what ends up happening is you wash away a majority of your nutrients and kill a lot of the soil microbiology.
1:12
The main benefits of cover crops are to help prevent erosion and nutrient loss from the soil think of cover crops as a form of living mulch.
1:22
Now, we all know that mulch helps regulate the temperature of the soil.
1:27
It helps feed the soil as it breaks down.
1:31
It helps feed the microorganisms within the soil.
1:36
It also helps keep the soil from being exposed to the elements.
1:40
Well cover crops, do the exact same things and more cover crops also help smother weeds,
1:47
control pest control disease and help your soil retain moisture.
1:53
Not to mention that cover crops will also help increase the biodiversity within your garden or farm.
2:00
So how do cover crops work every time we plant something in our garden,
2:06
whether it be tomatoes, radishes,
2:08
beets, carrots, lettuce,
2:10
it doesn't matter. It is drawing nutrients from the soil.
2:15
Each crop will draw a different nutrient from the soil.
2:18
After we harvest our crops, we need to make sure that we are returning the nutrients back to the soil.
2:24
And that's something that you get from cover crops.
2:27
Now, there are many different type of cover crops that you can plant in your garden.
2:32
How do you know which ones to plant? Well,
2:34
it depends on what time of year you're planting these cover crops and it depends on what you grew in the bed right before you plant these crops.
2:42
Each cover crop can help revitalize a specific type of nutrient within the soil.
2:48
So when people use the term cover crop,
2:51
they're talking about more than one type of crop.
2:54
Now the cover crop you decide to plant also is determined by how long you plan on leaving it in your garden.
3:01
If you plan on leaving this cover crop for a long period,
3:04
then you should be planting a small cereal grad.
3:08
I'm talking oats rice barley or other grains like that.
3:12
If you plan on cover cropping for a short period of time,
3:15
then we need a fast maturing green cover crop.
3:19
These quick growing cover crops will help out compete the weeds in your garden.
3:23
Example of quick growing cover crops are things like buckwheat and peas.
3:28
Now, one of the secrets when it comes to cover cropping is to make sure you allow the plant to mature as long as possible,
3:36
but you wanna make sure you get to it and cut it down before it creates its seeds.
3:42
Because if we allow the seeds to form those seeds will fall,
3:46
plant will self seed and then you end up in a cycle that you definitely don't wanna be in.
3:51
So since cover crop is the equivalent of a living mulch at some point in time,
3:56
we're gonna have to kill this cover crop.
3:58
This is part of how we help reinvigorate our soil.
4:02
Now, here are the three main ways that gardeners kill their cover crop.
4:06
And when I say kill, I mean, purposely kill,
4:10
you can mow it down, you can grab your weed eater and just chop it down or you can grab a big pair of loppers and cut it all down after we plant the cover crop.
4:21
At some point in time, we're going to have to kill it.
4:24
Now, I know that may sound bad, but hear me out,
4:28
our goal is to plant these oats or grains and allow them to grow in our soil.
4:34
But the magic of the cover crop really happens when we work this green material back into our beds.
4:41
So at some point in time,
4:43
we're gonna have to cut it down. Now,
4:47
three of the easiest ways to cut your cover crop down are one by mowing it.
4:52
Two, grabbing your weed eater and chopping it down or three,
4:57
grabbing your favorite pair of loppers or pruners and cutting it down.
5:01
Now, after we cut the cover crop down,
5:04
our work is not done, we now need to turn over the soil and work this cover crop into our garden.
5:12
Now, I know I always talk about no till gardening and I am still a big fan of no till gardening.
5:19
But this method of tilling the fresh cut greens back into our garden does more good than it does bad as this cover crop breaks down in our soil.
5:30
It helps to strengthen and feed the soil food web.
5:33
Now, I personally have some friends who are so no till that they won't even till their cover crop into their garden.
5:41
As a matter of fact, on their farm, what they do is they grow the cover crop,
5:45
they mow it down and then they allow it to break down naturally into the garden.
5:51
They use the clippings as sort of a mulch.
5:54
But one reason why I don't like this is because it prevents them from being able to work and grow in that garden bed.
6:02
Or really, they're on a farm, it prevents them from being able to work or grow in that row for the next season while the greens break down.
6:12
So even though I am a big fan of no till gardening every now and then it's ok to till the cover crop into the garden.
6:22
The main thing about no till gardening is you don't want to work the soil deeply.
6:28
Now, if you're a backyard gardener cover cropping may seem a little bit excessive.
6:35
But if you live in an area that has harsh winters or you don't plan on gardening in the winter or summer because you don't like the temperature extremes,
6:44
then cover cropping is a great way to make sure that your garden is still being nourished even though you're not using it now cover cropping isn't for everybody.
6:55
I just wanted to tell you what it was in the event you decide to give it a try.
7:01
So now that we know what cover cropping is,
7:03
let's talk about a few different cover crops that you can grow in your garden first,
7:08
let's list off the summer. Cover crops.
7:11
One buckwheat, two cow peas,
7:16
three sorghum grass,
7:19
four wheat, five Austrian peas.
7:24
Now, for a winter cover crop,
7:26
you're gonna be looking to plant one of these,
7:29
one crimson Clover,
7:31
two annual rye,
7:34
three hairy vetch,
7:37
four wheat, five Austrian peas.
7:42
You'll notice that wheat and Austrian peas can be planted in both the winter or the summer.
7:49
Now, remember cover crops are often used during time periods when the temperatures don't really allow us to be out in the garden when it's extremely hot in the summer,
7:58
or it's extremely cold in the winter, rather than leaving your soil exposed to the elements,
8:05
you should just cover crop it or mulch it.
8:09
If you don't know all the benefits of mulch,
