Spring Onion problems

Keep mix evenly moist for shallow roots, like a wrung-out sponge, without leaving the base soggy. Water when the top 2–3 cm feels dry, then soak until excess drains. Steady moisture keeps leaves tender; long dry spells make growth tough and can push plants toward bolting. In practice, water check containers daily in warm weather; shallow pots may need water every one to two days, while larger troughs often need about 3–5 cm of water per week. Press a finger into the top 2–3 cm of mix; water when it feels dry and the pot feels light, then irrigate until drainage runs clear. Containers dry faster than in-ground beds in summer; cut back only when growth slows in cool weather or after a heavy harvest cycle.

Spring Onion needs bright, indirect light for steady indoor growth.

Spring Onion is toxic to cats, dogs, and horses. Keep out of reach of curious pets and choose pet-safe alternatives for accessible spots.

Propagate Spring Onion from healthy stem or root divisions during active growth.

Use loose, fertile, well-drained loam or sandy loam with moderate compost; pH about 6.0–7.0. Avoid heavy clay and constantly waterlogged media. A good mix includes 40% quality vegetable potting mix or screened loam, 30% mature compost, 30% perlite, coarse sand, or fine grit. Excellent drainage is essential; bunching onions rot quickly in soggy, poorly aerated mix.

Repot Spring Onion no routine repotting — sow seed or plant divisions in the final container or bed for the season; perennial clumps can be lifted and divided every few years in mild climates, ideally in cool-season sowing in local spring or autumn where winters are mild enough for overwintering clumps outdoors. Signs it needs a bigger pot: clumps are crowded with less than about 2–3 cm between plants, the planter is shallower than about 15 cm, drainage holes are blocked or the pot sits in standing water.
