Plans for the 2015 garden
are proceeding.
More focus
One model for
rapid-but-incremental development is to have periods of expansion followed by
periods of contraction. The periods of
expansion are periods of experimentation.
The periods of contraction are times of focus; focus on the varieties
that work, focus on the plots that perform well, focus on more precise
execution of planting and harvesting.
I expect to buy far less
garden seed this year than any year in recent memory. And I expect to plant a far greater
percentage of that seed. More doing and
less dreaming.
I will grow two varieties
of potatoes this year instead of the four I grew last year. I will not grow zucchini. When I want zucchini we will leave the doors
of the minivan unlocked when we go to church.
The plan is to grow one variety of broccoli, two types of cabbage, three
tomatoes and so on. I don’t try to grow
carrots anymore as I cannot stay ahead of the weeds. I will not buy melon seeds this year. They grow well for me but I do not stay on top
of harvesting them unless they are right in front of my eyes.
Crop rotation
One of the challenges of
growing a garden is to rotate crops to avoid disease and insect populations
building up. This may be partially an old-wives’
tale. Individual trees seem quite
capable of staying in the same place for extended periods of time and still
thriving. At least, I have never seen a
tree move very far of its own volition.
Rotating crops may be
prudent but it can be hard to pull off in practice. Conceptually, one must avoid planting cabbage
(for instance) in the same plot for three years before planting it there again.
The plants to avoid are cabbage and her
sisters: broccoli, Brussel sprouts, Chinese cabbage, collards, horseradish,
kale, kohlrabi, most oriental greens, mustard, pac choi, radishes, rutabagas,
turnips, and a few I probably missed.
Even if one moves the plots with religious devotion the bugs have little
difficulty finding their favorite meal in the new digs even if it is a couple
of hundred feet away.
Families of vegetables
The big groups are the
cabbage family (aka, cole crops or brassicas), the nightshades (tomatoes,
peppers, potatoes, eggplant et al), legumes (beans of all types, peas, clovers,
lentils, etc.), maize (sweet corn, popcorn and field corn) and the vining
vegetables (pumpkins, squash of all types, cucumbers, melons, etc.). These families of vegetables share common diseases and insect pests within the family.
Strategies
One could go bat-dip crazy
and simply grow all one family in any given year. One year might be the year of the beans. The next the year could be the cabbage and so
on in a vegetarian version of the Chinese calendar. Even that can fail. Clover, nightshade and brassica species are endemic
in-the-wild. And then there is the issue
of controlling your neighbor. They might
grow vegetables willy-nilly. I do not advise bombing his garden with
herbicide even if you see him as Typhoid Mary.
It is not very neighborly.
My current plan is to grow
the vining vegetables next to the road.
It is a plot that is approximately 110 feet long by 25 feet across (33m
x 8m). That plot has gotten narrower because
I have been planting Illini Hardy Blackberrys along the road to feed the
natives and to act as poor-man’s barbed wire.
There are also some climbing roses sprinkled into the blackberries, some
Dortmund, Laguna and R. canina. Most of
the vining vegetable area will be dedicated to winter squash, C. maxima (Golden
Hubbard), C. pepo (Winter Luxury) and C. moschata (Dickinson).
Sometime in July I will
broadcast a brassica wildlife foodplot seed mix into the patch. The seeds will germinate in the shade of the
squash/pumpkin leaves. The little turnip
and kale plants will sulk until powdery mildew starts killing off the squash
leaves and more sun hits the little seedlings.
The most efficient way to
add organic material to soil is to grow it in place. It is way easier to sprinkle two pounds of
seed than to spread 12 bales of hay. It is pretty easy to tell if you are adding organic matter (i.e., sequestering carbon in liberal-speak), a patch of ground is adding organic matter if it is green.
The fact that the turnip and kale plants are "cabbage" complicates crop rotation. Everything comes at a price.

The nightshade species will be in
the plot a bit north of the house. That
plot is about 100 feet long by 60 feet wide (30m x 17m). The picture in my head is to plant mostly
potatoes (2/3 Missaukee, 1/3 Spartan Splash) with one row of tomatoes and a
half row of peppers.
The “big” garden is
southwest of the house. It is 90 feet
long by 75 feet wide (27m x 22m). This
was in potatoes last year. The east end somehow
morphed into a tree nursery after a bunch of acorns were planted there.
This year the big garden
will be “everything not vining or nightshade”.
The green beans (Provider for the first planting, Jade or Derby for
subsequent plantings) will be planted in increments of 20’ double-rows planted
every two weeks. A double row attempts
to increase plant density while retaining a rototiller-friendly between-row
distance by having two, closely spaced rows and then the normal
rototiller-friendly distance. The ground
between the two closely spaced rows quickly becomes shaded and the weeds are
puny and easy to pull. The bean seeds
will start going into the ground June 1.
The green beans will be
followed by turnips and kale. Green beans are
sprinters. They cannot go the
distance. So the canny gardener develops a relay-race strategy. The bean
plants will be pulled after two weeks of intensive picking (and as the next
planting comes on-line) and cold, short-day loving plants will be planted in
their place. If I am really “good” I
will seed the turnips and kale into the strip between the double rows of beans several weeks before I cut the bean plants down.
One of the things that
tears at a gardener’s heart is the management of his main season cabbage,
Brussel sprouts, beets and rutabagas patch.
These plants/seeds want to go into the ground on July 4th
weekend. They are biologically wired to
be the industrious ants of the plant kingdom, storing up carbohydrates and
protein in the shortening days of late summer and autumn so they can get the
jump on those slackers, the annuals. What
does one do with the plot of ground that will not receive their main crop until
half way through summer? Letting weeds
grow is not a good option and there are very few crops (how many green onions
can a person eat?) that will be done by then.

The very earliest lettuces
can absorb some of the ground.
Micro-greens are for sissies. I
refuse to grow anything so small that it is harvested with scissors the size of
my wife’s tweezers. So far, my best
solution is to put in a “green manure” crop of red clover or fava beans. An additional benefit of fava beans is that they "extrafloral nectaries", that is, nectar glands that are not in the flower. Those nectar glands can feed predatory wasps and keep them on the job hunting and killing garden pests. Peas are
also an option, but most modern pea varieties are tiny plants so you have to
plant many pounds of peas to ensure a good canopy of leaves to suppress weeds. If you are Biblically oriented, the legumes
will be my John the Baptist crop. They
must diminish so the one(s) who come after can increase.
Miscellaneous
A couple of other changes
will be to plant pole beans next to every bit of garden fencing. I let the Captain graze his cattle on my
pasture to keep it from turning to brush.
The cattle will probably eat all of the bean vines, but it is worth a
try. I also need to figure out how to
add a booster pump into my line out to the big garden. It is far enough from the house that I lose
too much head to run two impulse sprinklers at a time. I also need to refine my grass lanes to
facilitate moving about the garden.
Hey ERJ,
ReplyDeleteIf you put a dark tarp down and anchor it very well, it will kill the weeds. Do this after rototilling, and give it about six weeks to "cook off" the weeds and their seeds. It keeps new weed seeds out, and moisture in. Use twice as many anchors as you think you will need, like a brick every two feet- you don't want the tarp moving in strong winds.
