Shaded band shows the sourced low-to-high pound-yield range. The line tracks the midpoint for quick comparison.
Method: direct pound yield from crop metric source. Annual crops assume one comparable planting per year; perennial crops ramp from first bearing to full production.
Planting Strategy
- Planting depth: Transplant deep, burying the stem up to the lowest healthy leaves.
- Container minimum: 5+ gal (good). 5+ gal per plant; 10+ gal is better for full-size indeterminate varieties.
- 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.
- Use the pairing map below to choose nearby companions or compatible varieties.
Risk Factors
- Match the site first: full light, loam soil, and medium water.
- Use 1.5-2 ft in-row x 4 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 3-8 ft H x 2-3 ft W.
- For harvest planning, treat "large slicing tomatoes in summer" and 8-20 lb/plant/season as planning ranges, not guarantees.
- Local drainage, pests, chill hours, wildlife pressure, and microclimates can change the result.

Plant Nearby
Classic kitchen-garden pairing: marigolds add season-long flowers near tomatoes and help draw beneficial insects into the bed.
Use it: Use marigolds as edge plants or small pockets near the tomato row so they do not crowd airflow around the tomato stems.
Basil fits the same sunny, warm, regularly watered bed as tomatoes and keeps harvest tasks clustered together.
Use it: Tuck basil at the front or aisle side of tomato beds where regular picking is easy and tomato shade is limited.
Warm-season vegetables benefit from nearby flower strips that keep bloom and insect activity close to the crop bed.
Use it: Use a narrow flower strip along the vegetable bed edge so beneficial insects are nearby without reducing crop spacing.
Sources & Methodology
This guide combines hardiness range, light, soil, water, harvest timing, traits, source listings, 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.
