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.

For soil forcing, choose a pot that holds bulbs close without touching and leaves room for roots below them. Bulb count determines diameter; the dense flower spikes should not be used to justify an oversized wet pot.

For soil forcing, choose a pot wide enough to place bulbs close together without touching and verify enough depth for roots below them. Leave the bulb noses above the mix; diameter depends on bulb count, not flower height.

Choose a draining pot about 1–2 inches wider than the crown and verify usable depth for the plant’s developing taproot. Parsley benefits more from adequate depth than from an unnecessarily broad wet container.
