How to Grow Romaine Lettuce from Seed
Sowing and Germination
Direct sow or transplant in early spring, and again in late summer for a fall crop, avoiding peak summer heat. Thin seedlings early.
Care and Harvest
Keep moisture consistent, as uneven watering plus heat causes bolting and bitterness, and mulch to hold moisture. Feed with a balanced organic fertilizer every 2-3 weeks. Cut outer leaves as needed or cut the whole head at soil level, ideally in the morning. Sow new seeds every 2-3 weeks for a continuous harvest.

Standard paper seed packets are permeable to oxygen and moisture -- the two primary causes of seed degradation. Most paper-packaged seeds begin losing germination viability after approximately one year, contributing to significant garden-industry waste: packets purchased, not planted, expired, discarded. Shido Seeds are hermetically vacuum-sealed. The packet does not expire quietly in a drawer. It waits.
Every Shido seed packet is illustrated in the style of Japanese 1910s woodblock printing -- designed and drawn in-house by Chive, the Toronto ceramics studio that has been exhibiting at the Chelsea Flower Show in London every year and does not, as a matter of principle, sell to big-box retailers. Customers collect the packets as a series. This was not the original plan.
