Planting Calendar for Seattle, WA

Enter your zip code or postal code above.

The planting calendar below tells you when to plant in the SPRING and also plant in the FALL, based on your zip code or postal code.

Spring Planting Calendar

Our spring planting calendar starts with the very first dates that you can plant (based on the last spring frost). But if you've missed these dates, no worries! This is why we've added "last planting dates" to our spring calendar; this is meant to help new gardeners understand that if they missed the first spring planting window, they could still get crops in the ground.

In fact, many crops with short maturity times (such as radishes) can be succession planted all the way through the summer in northern areas. However, note that some cool-season crops, such as kale and lettuce, do not grow well in hot temperatures, which can cause bolting issues.  For some gardeners, especially in the South, a break to avoid summer heat is needed, but they can start once the heat has passed. 

The dates provided are based on the number of weeks before or after frost, so we can provide a unique calendar to every user in the country. Thus, several crops (especially similar crops) may appear to have the same date. Kale and lettuce, for example, or dates for starting seeds, like broccoli and cabbage. 

Fall Planting Calendar

When we say "fall," we really mean planting in summer in time for a fall harvest. Think of this as a second summer! It's easy to keep the crops going if you've already prepared the soil! 

Many crops that would be started indoors for a spring crop can just be plunked into the soil directly for a fall crop. Not only is the soil already warm but also there are less pests and it tends to be rainier so you don't need to water as often. Some fall vegetables need to be harvested by the first frost, but many are frost-tolerant and even taste better after a kiss of fall frost!

See each plant's individual Growing Guide for more specific planting, plant care, and harvesting information.

Specifically, on the charts, there are different columns labeled as follows:

  1. Start Seeds Indoors: When to sow seeds indoors to get an early start on the season.
  2. Plant Seedlings Outdoors: When to put small seedlings that you grew indoors (OR starter plants that you bought at a garden nursery) in the outdoor soil.
  3. Start Seeds Outdoors: When to plant seeds directly into the outdoor soil.
  4. Last Date to Plant: You may plant any time from the "start seeds" dates until this "last date." Don't wait any longer, or the crop won't have time to get to harvest before fall/winter frosts.

The "Moon Dates" indicate the best planting dates based on Moon phases. You can learn more about this age-old technique below.

When N/A appears in the chart, that starting method is typically not recommended, although it is likely still possible.
