Keep a flowering primrose close to its nursery root-ball size, moving only about 1 inch wider when repotting is necessary. The flower display spreads beyond the small fibrous roots and should not determine diameter.

Choose a stable pot about 1–2 inches wider than a young root ball. Eucalyptus grows rapidly and eventually becomes a tree or large shrub, so confirmed indoor sizes are temporary stages—not a way to keep a mature plant small.

Choose a draining pot about 1–2 inches wider than the woody root ball. Rosemary needs room for roots but suffers in a large volume of slow-drying mix; strong light and airflow matter more than generous diameter.

Choose a pot about 1 inch wider than the measured root mass. This plant spreads by short underground rhizomes, so a modest width increase is more useful than a deep reservoir of unused, wet mix.

Choose a container 1–2 inches wider than the measured root ball for a compact Camellia japonica. Mature shrubs can outgrow the available range, so indoor display works best for young plants in a cool, bright place.
