Growing Guide

When to Grow

Start seeds in late spring, roughly 118 to 132 days before your first expected fall frost, and transplant when the seedlings are 4-6 weeks old so the plants still get their full 90 days in the garden. Red Rubine is particularly well-suited for fall harvests, as cooler weather intensifies the color and flavor. If you're not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds 1/4 inch deep in seed trays or pots filled with quality seed-starting mix. Maintain soil temperatures between 50-75 F for optimal germination, which takes 7-10 days. Transplant seedlings into the garden when they have two sets of true leaves, spacing them about 24 inches apart, with rows 24-36 inches apart.

How to Grow

Plant Red Rubine Brussels sprouts in full sun and well-drained soil with a pH of 6.5-7.5. Ensure regular watering and feed with a balanced fertilizer every few weeks. As plants mature, remove lower leaves to promote sprout development. Harvest sprouts when they reach 1-2 inches in diameter, starting from the bottom of the stalk.

How to Save Seeds

Red Rubine Brussels sprouts are biennials, meaning they flower in their second year. To save seeds, let some plants overwinter in the garden. In spring, they will produce flowers and seed pods. Once the pods dry, harvest and thresh the seeds. Store seeds in a cool, dry place.
