## Description

Walla Walla Sweet Spanish Onion Seeds (Allium cepa) – 300+ Non-GMO Heirloom Seeds by Isla’s Garden Seeds, Extra Sweet & Mild Flavor, Large Bulbs Ideal for Slicing & Cooking, Cold Hardy & Reliable

## Features

- This sweet variety is an overwintering type that's good for fall or early spring sowing in the north! Plant the seeds 1/2" deep in a flat 2-3 months before the last frost date; keep the soil moist and at room temperature. When the tops begin to flop over, cut them off to 3" to focus the growing on the roots. Four weeks before the last frost or when the soil reaches at least 50 degrees F, transplant the seedlings 6" apart in rows 12" apart.
- Seeds are great for Planting in Garden or for storing in a seed safe for an emergency. Onions need moisture especially in their first several weeks of growth, and they cannot fight against weeds; mulching onions can help with both moisture and weed control. Walla Walla onions are not attractive to deer; they also tolerate cold well.
- Biennial. 115 days. 12-18" height. 4-6" spacing. Produces sweet brown skinned, white onions of a large size. Long day variety.
- Latin Name: Allium cepa Type: Open Pollinated, Heirloom, Cool Season|Warm Season
- Hardiness Zones: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
