Converting a lawn into a garden

Most American lawns produce no food, support little wildlife, demand consistent water and mowing, and exist mainly because of mid-20th-century suburban convention. There's no inherent reason a yard needs to be lawn. The first step in converting it is granting yourself the permission to do so.

The instinct is to strip the sod. Don't. Sheet-mulching is dramatically easier and works better. Cardboard directly on the lawn, compost on the cardboard, mulch on the compost. The grass dies under the cardboard; its roots decompose and feed the new bed; the cardboard breaks down within a season. You go from lawn to productive bed in a few hours of work and 3–6 weeks of wait.

Patricia Lanza's *Lasagna Gardening* (1998) is sheet mulching under a friendlier name. Same technique; better marketing. If 'sheet mulching' sounds technical, 'lasagna gardening' may not. Either way: layers of organic matter on top of the lawn, broken down by biology, ready to plant into.

The sheet-mulched bed needs compost as its top fertile layer. Start a compost system before you start the conversion. Household kitchen scraps + lawn clippings (one last use of the mower) + fall leaves = enough compost within months for a small bed. The transition from lawn to garden runs on what was previously waste.

An alternative to sheet mulching: build raised beds directly on the lawn. The same lawn-killing principle — block light, build above — but with defined frames and imported soil. Faster to plant into; more expensive than sheet mulching. Either approach works; many converters do some of each.

The bed nearest the kitchen door gets used most. Convert that lawn area first. Salad greens, herbs, daily-pick crops. The lawn closer to the road and farther from the house can wait; the lawn that becomes Zone 1 first is the lawn that pays back fastest.

↓ leads to

A newly sheet-mulched bed in its first year is fertile but biology is still establishing. Choose forgiving crops: bush beans, lettuce, summer squash, chard, kale. These produce abundantly in fresh organic material. Save tomatoes and brassicas for year two when the bed has more equilibrium.

↓ leads to

Lawn at least kept the surface covered. The converted bed needs continuity of cover too — cover crops in fall, mulch in summer, succession-plantings keeping beds occupied. A converted lawn left bare grows weeds; a converted lawn kept covered keeps building soil.

Yard-to-garden conversion is a quiet form of bioregional repair. Lawn-to-pollinator-habitat. Lawn-to-rain-garden. Lawn-to-vegetable-bed. Lawn-to-native-plant-meadow. The aggregate effect, across a neighborhood or a city, is substantial — for water management, for biodiversity, for food, for what kind of place the place becomes. Your converted yard is one node in something larger.
