Southern Willamette Valley Seeding Calendar

• January seeding in the greenhouse is for the pros, with two possible exceptions: Alliums and salad greens. Asian greens, mustards, arugula, bok choi, especially, are strong germinators in cool soils, with no supplemental heat required. Plant out by early March, harvest by early April. The fast, early crop. Wherever possible, use freshly-saved seed – freshness lends significant impetus to seedling vigor at this time of year.
• February is the month in which inexperienced gardeners tend to sow too early. You will lose little and gain greatly by waiting. However, with appropriate resources, commitment and incentive, February is the month advanced gardeners get serious about season-extension in the greenhouse.
• For direct seeding without the assistance of a propagation greenhouse, the spring seeding schedule takes the following course: there is pea and fava bean planting time in the weeks around Valentine’s Day. Then it’s time to direct-seed cool-weather spring greens. Then corn, then squash, then beans. The pea/fava planting time still has hard freezes and is mostly cold weather, but with occasional cool periods. Peas and favas can grow when the temperature is not much above freezing. The cool-weather greens can tolerate freezes, grow well in cool weather, and have photo-period requirements that fit this schedule. The early corn-planting time can still have occasional light freezes – but the weather then is still considerably warmer than earlier in the season. Corn needs warmer weather to make good growth than peas or favas do, so there is little point trying to get it in earlier than this. Squash and beans are normally killed by frost, and thus are put in after most danger of frost is past. Timings suggested in the seeding calendar below, include the earlier sowing times for transplants afforded by ‘indoor’ propagation aids, such as greenhouses or, for home gardeners, hotframes or basements with supplemental light and heat.
