Do It
Nature's Way
(The no
dig method of gardening.)
by Jim
Haworth
Do you enjoy pulling weeds? How about hoeing between the rows
every week in the hot summer sun? Does your garden get tilled every spring and
also in the fall? Do you use an expensive power tiller or old-fashioned shovel
and rake?
Is there a compost pile in the back yard? Do you turn it over
every few days and faithfully water it? Later, do you screen out the big lumps
and use a wheelbarrow to transport the brown gold to the garden and spread it
around?
Is all this work really necessary to have a great garden?
No, it's not! You don't have to do it the hard way. There's
another way.
Year
round mulch
Sure, you've
used mulch before. Perhaps you spread a thin layer of grass clippings or wood
chips around your shrubs and trees. Think about a layer at least 3 to 4 inches thick
and left on year round. Picture it covering your entire garden. Can you see the
blanket of leaves, wood chips or hay with your plants growing up through, tall
and vigorous?
What you won't see are weeds.
Down on the ground underneath everything, where the weed seeds germinate, it is
perpetual night. Even if they manage to sprout, very few will have the energy
to grow up through the mulch to get to the sunlight. Don't shed a tear for the
weeds. They grow just fine in other
people's gardens.
Have you ever
been in the woods and stopped to examine the soil? First you have to push aside
a layer of leaves or pine needles to get to the dirt beneath. It's moist,
black, fluffy, and smells good. Even non-gardeners somehow know it's an
excellent soil for growing things. Wouldn't it be great to have garden soil
like that? Mulch will do that for you.
Consider what
woodland soil is made of. First there's the mineral part, sand, clay, rocks
etc. Just like your garden is now. Forest dirt is almost always covered with a
layer of organic material that is continually decomposing and being worked into
the soil. Things like old leaves, twigs, rotting wood, and bodies of dead
insects. The soil also contains a large assortment of flora and fauna, much of
it is microscopic. These creatures break down organic material and work it
into the soil.
The richness of the soil comes
initially from plant residues. In the decomposition process organic material is
broken down into nutrients that are taken up by the plant roots. Dead plants
are recycled back into live plants. Mulching just duplicates this natural
process.
What
can I use for mulch?
What have you got? Leaves,
twigs, nut shells, pine needles, spoiled hay, wood chips, straw, chopped up
Christmas trees, ground corn cobs, peanut hulls, old flowers, weeds, shredded
newspapers-use your imagination.
Towns and cities often chip
tree trimmings and allow residents to pick them up for their home gardens. I
use my station wagon in the fall to pick up bags of leaves left out at the curb
by my neighbors. A foot thick layer of leaves becomes 4 to 6 inches by spring.
Some mulches are tidier looking
than others. One material that I advise against using is any plant residue that
you know is diseased. Putting it next to your healthy plants will spread the
disease to them.
If the mulch is organic,
chances are it can be turned into that rich, black earth we love so well.
Mother earth is a great recycler.
What about kitchen garbage?
Sure! But just as when you make compost, don't use meat products or bones that
will attract vermin. To keep things looking neat, simply tuck garbage items
under the mulch. Out of sight and no smell. In effect you are making compost
right on the site where it will be used by your plants.
It's hard to use too much
mulch. Given enough time, it decomposes completely. During the summer it breaks
down the fastest but the process continues well into the winter because a thick
blanket retards the penetration of the frost. As the cold continues, however, activity
of all types slows down and almost stops completely. You may find that the
ground doesn't freeze under the mulch because it is so thick that it insulates
the ground and keeps it from freezing.
Many people complain about the plants
they lose over the winter. Try mulching to keep the frost out of the ground or
at least reduce its penetration. Use hay or straw or something similar to
prevent compaction, which will reduce the insulation value.
Won't the weeds
grow through the mulch? Look at it this way, would you plant your carrot seeds
or squash seeds in the ground then cover them with several inches to a foot of
grass clippings or wood chips? No, because you know they can't grow through
that much darkness to reach the sunlight. There just isn't enough energy in the
seed to allow the plant to grow that far without getting energy from the sun.
Weed seeds are not able to do it either. If you do get weeds, you may have let
the mulch get too thin. If the weeds pop through you can either pull them up
then add more mulch, or just cover them with a big pile of mulch and maybe
you'll smother them. Weeds will pull up easily because the ground is moist.
Water
When you have nothing to cover
your garden soil, the sun bakes it. It becomes dry and hard. Weeds love it
because when you try to pull them out, they just break off, leaving the roots
to grow again. Hard soil protects weeds. Naked soil is unnatural. Can you think
where on earth bare soil is found naturally? How about the desert?
Well, we don't want a desert
garden so we have to add water. Often. The moisture is good for the plants, but
also germinates more weed seeds.
Remember the idea is to grow the plants we want and at the same
time discourage weeds. Because my garden is mulched, I seldom water even in dry
summers, unless I'm bored. As insurance against really dry times, I have soaker
hoses under the mulch, next to the soil. Soaker hoses are made from recycled
automobile tires and they are cheap.
The thick mulch allows rain to
penetrate to the ground, then it holds in the water where the sun can't reach
it, but the plant roots can. During heavy rains this covering slows down the
penetration of the water. This helps prevent soil erosion during gully washer
storms.
Organic mulches reduce soil
splashing during heavy rains. This keeps vegetables cleaner. It also reduces
puddling and its aftermath, a hard crust on the soil surface. Some areas have
watering bans during summer droughts, but this usually doesn't bother gardens with
thick mulch. Mulching actually conserves water when it matters most.
If you don't
want to commit to a whole garden under a year round mulch, please try it on a
small portion, then expand your mulching area as you see its benefits.
Planting
Are you wondering how your
plants are going to grow through all that mulch covering your garden? They
can't.
When you plant
seeds, you just pull back the mulch until you have exposed the soil, perhaps in
a row. You just need a narrow ribbon of soil, only wide enough for the seeds.
Sprinkle the seeds as usual and cover with a little soil, tamping lightly. As
the plants sprout, gradually bring the mulch up to them, a very thin layer at
first then thicker as they get taller.
Plant sets,
such as peppers or tomatoes, can be put in the ground but don't immediately
bring the mulch up to the plants. They are of tropical origin and need warm
soil. Pull back the mulch in the early spring. Give the ground a few weeks to
warm up, put in the plants, then push a thin layer of mulch up to the stems.
Again, increase the depth as the plants get taller. If you let the tomatoes
sprawl without using cages, the mulch will keep the fruit cleaner than if they
were left lying in the dirt. I should also mention that tomatoes that lie on
the ground or the mulch may invite mice to sample your fruit. If you have the
tomato plants in cages or stake them, the mice won't climb the plants to get to
the tomatoes.
A few weeks before putting in
seeds for plants that need warm soil, pull the mulch aside just enough to
expose soil to the sun and warming temperatures. Only pull it back for the row
or hill where the seeds go, don't take the mulch off the whole garden. As the
seedlings begin to grow pull the mulch up to the new plants.
Potato sets are placed on top
of the ground and covered right away with a few inches of mulch and as they get
taller the mulch is piled to at least a foot in height. Many of the new
potatoes will form inside the mulch instead of in the ground. No hilling is needed.
There may be a few formed in the ground. They can be dug up to eat or left for
next year's crop. At no time let the tubers grow in sunlight, it’s been said
this makes them poisonous when they turn green. It’s not something I care to
test.
Let me insert a note of caution
regarding newly cut green mulches. This would include things like green grass
clippings and chipped tree trimmings. They both have leaves or stems that
decompose rapidly producing a lot of heat. By that I mean heat so intense that
if you made a large pile of them, in a few days you could put your hand deep
into the pile, but you couldn't hold it there for more than a few seconds.
Don't put large quantities of this mulch right up against your plants. Keep it
several inches away. Perhaps you could scatter it on top of the mulch that's
already there. In a short time the heat will dissipate from the material and it
will be safe to use anywhere.
You know better than to use
grass clippings that have been sprayed with weed killer, don't you? Thought so.
Expanding
your garden
If you begin to use these
methods, you will see that the garden requires much less work, the temptation
will be to expand it. Leave the tiller in the garden shed. You can prepare the
soil without it. Quickly, easily and without pulverizing the earth.
During the summer or fall, just
mow the grass as usual, cutting it as low as the mower will allow. If you're
really ambitious, use a weed whacker to scalp the ground. Then place a good
thickness of mulch over the spot you will be using next year. The grass and
weeds will exhaust themselves trying to grow and by spring there will be bare
soil under the mulch. Their dead roots will help loosen the soil and allow
water to penetrate.
This would be a good place to
use the green mulches mentioned earlier. The heat will kill the vegetation even
quicker than the lack of sunlight, at least the part that is above ground.
Insects
Will insects be
a problem? They will be there for sure, but a problem? -Probably not.
You will notice the mulch is
alive with bugs. Never fear, this is natural, they are playing the part they
are supposed to. They are breaking down
the mulch into smaller particles and then the microscopic critters are
completing the job. If they are not bothering your garden plants, by all means
leave them alone.
You will find that your garden plants may show a nibble here and
there, but it may be less than you've seen before without mulch. This is
because the mulch also provides living quarters for insect predators. Their job
is to keep the bad guys in check. Leave them alone also.
During wet
summers slugs can be a problem. They eat your plants and leave slime trails
everywhere. Some books advise you to pick them up and drop them into a can half
full of kerosene or detergent and water to kill them. Yuck!
I put a couple of saucers near
my plants in the evening and pour in some beer. No, I don't tell my wife when
I'm using the family dinnerware for this, but it's for a good cause
anyway. At night, the slugs smell the
hops in the beer and crawl in and drown themselves. The next day I dump them
out and add more beer. The only thing wrong with this method is that it seems
like a waste of good beer, but we all have to make sacrifices.
No one has to
tell you that earthworms will be present in abundance. They eat dead plant
material and mix it into the soil. They constantly aerate the soil, make it
fluffy, and bring nutrients to the plant roots. There's no need to dig, just
let the worms do all the work!
Avoid artificial insecticides
whenever possible. There are many books written about safe alternatives to
insecticides. There just isn't room enough in this article to cover all the
information available in these volumes. Please read them. Dumping pesticides on
your plants will kill vast numbers of beneficial insects and worms that are
working so hard to make your gardening successful.
So try this natural method of
gardening, its advantages and rewards are many.
Read
the book!
There are a few
books on this subject and they will give you a more in depth look at year round
mulching techniques.
About forty years ago Ruth Stout wrote a few books on the
subject. They are out of print now but may still be found at some libraries and
used bookstores.
