Data quality

Medium profile, No pound-yield source

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.

Planting Strategy

• Planting depth: Set the crown at the same level it grew in the nursery pot.
• Container minimum: 2+ gal (good). Use 2+ gal per plant, or wider mixed containers with similar water needs.
• Start with one plant when testing fit in a new bed or container.
• Use the pairing map below to choose nearby companions or compatible varieties.

Risk Factors

• Match the site first: full light, loam, clay soil, and medium water.
• Use 1-3 ft in-row x 1-2 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
• Plan around mature size: 1-5 ft H x 1-3 ft W.
• Plan pollination or companion context before planting; nearby varieties can matter for fruit set.
• Local drainage, pests, chill hours, wildlife pressure, and microclimates can change the result.
