The garden plan is the means by which, over time, the gardener maintains (and in some cases improves) the fertility of the soil while living on the produce. Tumbledown agrees with Gene Logsdon that "Rotation
of crops is important [for restoring nitrogen to the soil, for double cropping, and for insect and disease control], whether you are planning a few rows of corn in the garden or several acres on your homestead or several fields of a farm." (Small-Scale
Grain Raising)
Our rotation has been simplified (from six smaller fields in the vegetable garden to four larger ones) and has also become more complex (with more different crops grown in each field). Our rotation has also been evolving to fit our needs as a family (what the kids will eat and the cook will cook), while continuing to try to optimize space, maintain plant health (rotations to avoid plant diseases and pests), and retain or even build soil fertility. The simplified charts provided in this first section are explained in greater detail and rationales given for them in the description of the 2007 rotation (below) and in the chapters of this book that pertain to each of the individual crops.
| Spring | Fall | |
| Year 1 | Plow rye (or mulch) under. (See fall of Year 6.) Amend soil with peat, manure, compost, greensand and bone meal. Plant strawberries. Pinch all blooms, cut runners. Mulch with straw following light cultivation after two-four weeks. | Cover with pine straw when ground freezes. |
| Year 2 | Pick berries during June; continue to cut runners. | Pick fall berries on everbearing plants. Cover with pine straw when ground freezes. |
| Year 3 | Pick berries during June. Mow the row and plow under after crop dwindles. Amend soil. (See above.) Plant green beans (legume). | Plant winter wheat. |
| Year 4 | Sow alfalfa (legume; interseeded into the wheat) during last spring frosts. Harvest wheat in late June or early July. | Cut alfalfa once. |
| Year 5 | Cut alfalfa once. | Cut alfalfa once. |
| Year 6 | Plow alfalfa; plant broccoli; double crop to beans or a second crop of broccoli. (Incorporate the broccoli plant residues into the soil to inhibit verticillium. Whatever you do, don't plant members of the Cucurbitaceae or Solanaceae families before strawberries; that will only increase the chances that your strawberry plants will catch the Verticillium wilt!) | Plow beans (or harvest fall broccoli and plow in the chopped up plant residues) and plant rye cover crop (or cover with a light mulch). |
| Field 1 | Field 2 |
| Field 3 | Field 4 |
Each field has a number of rows, so the rotation is somewhat complicated. Again, the explainations and rationale for the rotations either follow below or in the individual chapters for each vegetable or grain crop. Since the complexity is hard to capture without multiple tables, I'll add tables each year so that a historical picture (a record of the rotations) emerges over time.

Tumbledown's
suburban
garden is small and the available ground presents significant
challenges, but (to paraphrase a regrettable public persona-non-grata)
"you garden with the ground you've got, not the ground you might wish
you had," until you can afford to move to better ground.
Tumbledown's garden consists of two distinct areas:
1) One area is low and soggy
much of the year.
(It is an easement which would require mowing if it were not a
garden.) This section is some 60' long and 10'
wide. The
rows run the length (East-West) at the bottom of a North facing
slope. Any gardener with experience will tell you that this
arrangement is less than optimal.
[Photo:
Easement; low area at bottom of North-facing slope with poor drainage.]
2) The other section is the
North-facing
slope. Tumbledown does not know the exact degree of slope,
but
the angle is too great to allow ordinary cultivation.
[Photo:
Slope in
winter with wheat and cover crops in place. The permanent row
in
the center is a combination of blackberry and raspberry.
Strawberries are currently in the two rows immediately in front of the
trellis.]
Without
terracing the
first hard rain would wash the whole hill down into the easement and
what little topsoil there is over the suburban construction-fill would
erode. Tumbledown cannot afford to install a real terrace, so
he
gardens in 20' garden strips (parallel to each other and perpendicular
to the direction of the slope) between equally large strips of sod.
[Photo:
Looking down the slope toward the easement, which is beyond the fence.]
Again, any gardener worth his salt would never stoop to such measures
(which any gardener can tell you will not work, since the sod will
always be competing for food and nutrients with the garden plants, and
the grass will harbor the pests that destroy a garden). But
this
is the land Tumbledown has and so this is the land he gardens.
There
is still debate about the effectiveness of crop
rotation
(for reducing pests and diseases and increasing soil fertility and
texture) in areas as small as most gardens. Tumbledown's limited
experience in this new location (since the 2004 garden season) suggests
that garden crop rotation, combined with mulching and cover crops, is
effective for adding humus, breaking up heavy clay, and improving the
texture of poor soil. If two or three years of such a
practice
can produce such noticeable results, it is a practice worth continuing
with hopeful expectation of even greater improvement.
1) The Strawberry -
Grain
Rotation. This rotation, entirely on the North-facing slope,
was
suggested by Gene Logsdon's book, Small-Scale
Grain Raising,
and has been adapted to Tumbledown's particular needs and
space.
For a full description of the process, see Tumbledown's Strawberry
page. This a six-year rotation, practiced at Tumbledown Farm
in
six, 20' rows as follows:
Year 1 Plant
Strawberries (blooms
pinched off, no berries harvested during the first year after planting)
Year 2 Strawberries
continue (harvest
begins in spring and, depending on the variety, may continue through
fall)
Year 3 Strawberries
continue (harvested
in spring); berries tilled under and row planted with green beans later
in the summer, after the berries have slowed; bean plants cut for
rabbit hay after two pickings and row planted in fall with winter wheat)
Year 4 Alfalfa sown
into wheat during
last spring freeze; wheat harvested in mid-summer; depending on
weather, may cut alfalfa once for rabbit hay during late summer.
Year 5 Alfalfa, cut
once for rabbit hay.
Year 6 Alfalfa is
tilled under; row is
planted with a deep-rooted, heavy feeding crop in the
spring. (Logsdon recommends corn, but because Tumbledown's
space
is limited and corn requires a four-row stand for adequate polination,
we must substitute other crops. We are still experimenting
with
several options to see which one best meets our needs:
Sunflowers, Sorghum, Millet and the like.) In the fall, the
row
is planted to Rye as a ground cover until the following spring.
2) The Vegetable - Grain Rotation. This rotation
includes
both the North-facing slope and the low-lying easement, and is again an
adaptation from Gene Logsdon's book, Small-Scale
Grain Raising.
This is also a six-year rotation, practiced at Tumbledown Farm as
follows: a) four sections of 15' rows (low ground on the
easement), with three rows per section; and b) two sections of 20' rows
(on the slope), with five rows per section.
Year 1 Corn (spring)
interplanted with
beans, followed by rye cover crop + some onions and garlic mulched
(fall)
Year 2 Peas (or,
more likely, salad
crops; spring), followed by cauliflower, brocolli, turnips, and kale
(summer-fall, whole area mulched with fallen leaves as winter
approaches)
Year 3 Tomatoes and
Peppers (spring), Rye cover (fall)
Year 4 Green Beans
(spring/summer), Winter Wheat (fall)
Year 5 Red Clover
(scatter sowed into
the wheat at the last spring freeze), wheat harvested in mid-summer;
may get one cutting of clover for rabbit hay in late summer or early
fall, depending on weather)
Year 6 Clover
continues (2 cuttings), tilled under in fall, covered with straw to
slow erosion.

Le Jardin Potager, Chapter 2, "Plan Du Jardin Potager" (Vegetable Garden Plan), by H. Spruyt, 1875. This is quickly becoming one of my favorite little garden books. Full of common sense. Chapter two is a general garden plan and chapter three discusses rotations, etc.
