Mache corn salad
Mache corn salad is an annual vegetable for USDA zones 3a-9a. It grows best in full sun, part sun and loam soil.
Is it right for your garden?
Mache corn salad is a space-and-pollination crop. Corn is wind-pollinated, so a few plants in one skinny row look good but often fill ears poorly; block planting and timing matter more than squeezing it into a small bed.
Best fit
- Full-sun garden blocks in its listed growing range with warm soil and steady water.
- Gardeners with enough space for a block of plants rather than a single row.
- Sites with good fertility because corn is a heavier feeder than most garden crops.
Use caution
- Plant in blocks, not one long row, for better pollination.
- Keep sweet corn and ornamental/flint/popcorn types isolated by distance or timing if seed quality matters.
- Drought during tasseling, silking, and ear fill can ruin the crop.
- Raccoons, birds, and earworms can take the harvest just as ears mature.
Regional notes
- In hot regions, early and staggered plantings help avoid peak pest and drought pressure.
- In short-season ZIPs, choose days-to-maturity carefully and plant once soil is warm.
- Small raised beds are usually better used for higher-value crops unless corn is a priority.
Comparison note: Compared with beans or tomatoes, Mache corn salad uses more space for less harvest per square foot. It earns the space when the gardener wants fresh-picked corn and can plant enough plants for pollination.
Planting and care
Getting started
- Planting depth: Sow 1-2 in deep
- Container minimum: 5+ gal (workable). Use 5+ gal for most single vegetable plants; smaller leafy/root crops can use less.
- Start with one plant when testing fit in a new bed or container.
- Plant more than one when harvest volume or pollination is the main goal.
What to watch
- Deer pressure: Not rated. No deer-resistance category is assigned yet; treat browsing risk as local and variable.
- Black walnut: Better near black walnut. Use as a black walnut / juglone planning cue; tolerance varies by cultivar, soil, and distance from the tree.
- Match the site first: full, partial light, loam soil, and medium water.
- Use 0.5-0.8 ft in-row x 2-3 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 5-8 ft H x 1-2 ft W.
- For harvest planning, treat "small rosettes in cool weather" and 1-2 ears/plant/season as planning ranges, not guarantees.
- Local drainage, pests, chill hours, wildlife pressure, and microclimates can change the result.

Spacing, yield, and timing
Spacing
Plant Mache corn salad at 0.5-0.8 ft in-row x 2-3 ft rows. Adjust this starting point for trellises, hedges, rootstock, containers, pruning style, or local extension guidance.
Expected harvest
Mache corn salad yield is modeled as 0.3-1 lb/plant/season. Treat that as a planning range, because weather, soil, watering, pruning, pests, and local pressure can change the real result.
Time to harvest
Mache corn salad usually reaches first useful harvest or display in 65-100 days under suitable conditions.
Growing conditions
Grow Mache corn salad in USDA zones 3a-9a with full, partial light, loam soil, and medium water. Use 0.5-0.8 ft in-row x 2-3 ft rows for layout planning. Match the plant to drainage, heat, chill, and pest pressure before scaling up.
Growing in a container
Mache corn salad can start with a container of about 5+ gal (workable). Larger containers usually buffer heat and moisture swings better than the minimum.

Method: ear-count range converted to pounds for stock-style return comparison. Annual crops assume one comparable planting per year; perennial crops ramp from first bearing to full production.

Companion plants and pairings
Plant Nearby
Corn, climbing beans, and squash can work as a warm-season guild when spacing, timing, and fertility are managed carefully.
Use it: Start corn first, add climbing beans after corn is sturdy, and give squash the outside edge so vines have room.

Sources and methodology
This guide combines hardiness range, light, soil, water, harvest timing, traits, supplier links, plant relationships, and quantitative planning metrics. Pairings are screened for practical garden fit.
Quantitative values use extension and botanical-reference ranges where available. For less-studied cultivars, similar crops fill gaps conservatively. Ranges are intentionally broad so the profile stays useful without pretending to be exact.
