Portland Vegetable Sowing Planner

I've put together a sowing planner for 2026 based on the seed catalog at East PDX Plant Club. You can download a copy to modify and save for your use.

Spring Sowing and Fall & Overwinter Sowing tabs. Each crop has: what to sow and when, best sow time (spring vs. fall vs. both, and which is primary), sowing rationale, succession interval and notes, weeks to transplant, and date columns where you enter your sow date and the transplant and expected harvest dates calculate automatically. You can also note whether you're planting in ground, in a grow bag, or a pot.

A few things that shaped the variety selection and timing:

The PNW climate has more in common with Japan, Korea, and northern China than with the Midwest or the Mediterranean. That shows up in the catalog: a lot of the varieties are Asian types specifically because they're adapted to cool, wet springs and mild winters. Kuroda carrots because they develop lateral roots in clay. Tatsoi because it overwinters and makes a great cover crop here. Kyoto Kujo Negi because it's a perennial bunching onion that comes back every year.

Fall sowing is underused by most home gardeners. The fall tab covers what to sow in July–August for fall harvest, what to start indoors in June–July for fall transplant, and what to sow in August–October for overwintering.
