Crystal White Wax Onion
✓ In your garden
Crystal White Wax is a white short day onion, ready in about 70 days. It’s a short-day onion — for the South (roughly below 35°N), where it bulbs on shorter days. Day length is the make-or-break for onions — pick the wrong type for your latitude and the bulbs stay small. Start from seed or sets in early spring.

Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around early May, well before your typical frost (~late Oct).

-
BeansTraditional
The most consistent 'no' in companion planting. Unproven, unanimous.

PeasTraditional
Same flag as beans — every chart agrees.
The badge is the honesty. Trialed = a published field trial · Practical = a real mechanism · Traditional = companion-chart lore. These pairings hold for every onion.

Growing Crystal White Wax — the things that trip people up
- Match the type to your latitude: long-day onions for the North, short-day for the South, intermediate in between — this is the single biggest factor in whether you get big bulbs.
- Onions are shallow-rooted and weak against weeds. Keep them weeded and evenly watered, ease off water as the tops fall over, then cure the bulbs in a dry, airy spot before storing.
