Pound return is the stock-style yield metric. These are planning ranges for comparing plants, not guarantees. Cultivar, rootstock, climate, soil, pruning, pest pressure, and wildlife can move actual results.

Right-size container with drainage
Containers / Before plantingUse a container large enough for mature roots, with open drainage holes to prevent root rot.
- View
Expanding container potting mix
Containers / Before plantingUse a lighter container medium instead of dense garden soil in pots and grow bags.
- View
Seed-starting trays
Propagation / Pre-seasonStart annual vegetables, herbs, and flowers ahead of transplant season.
- View
Floating row cover
Protection / At plantingProtect young crops from wind, light frost, and early pest pressure while still letting light and water through.
- View
Shade cloth
Protection / Heat wavesReduce heat stress for cool-season greens, tender transplants, and containers in hot sun.
- View
Low tunnel hoops
Protection / At plantingHold frost cloth or insect netting above seedlings so covers protect plants without rubbing leaves.

Seedling grow light
Propagation / Pre-seasonKeep indoor seedlings compact and sturdy before they move outside.

Nutrition / During growthFeed annual vegetables, herbs, flowers, and hungry container crops according to soil or label guidance.
Yield curve
Estimated Pound Return
Projected annual yield ramp from establishment to full production, using the current sourced range for Yukina Savoy.
- Year 1
- 0.5-1.5 lb First-year estimate from the sourced curve.
- Year 5
- 0.5-1.5 lb
- Year 10
- 0.5-1.5 lb
- 10-year total
- 5-15 lb/10 yrs
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: Sow 0.1-0.3 in deep
- Container minimum: 1+ gal (good). Small herbs, leafy crops, and radishes work in 1+ gal pots or wider shallow planters.
- 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.
Risk Factors
- Match the site first: full, partial light, loam, clay soil, and medium water.
- Use 0.5-1.5 ft in-row x 1-3 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 0.8-3 ft H x 0.8-2 ft W.
- For harvest planning, treat "glossy leaves in cool seasons" and 0.5-1.5 lb/plant/season as planning ranges, not guarantees.
- Local drainage, pests, chill hours, wildlife pressure, and microclimates can change the result.

Sources & 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.
