How to Plan Your Entire PNW Garden Season in 5 Minutes

If you are standing in your garden in April trying to remember whether it is too late for peas, you already missed the window. Not because you did anything wrong but because you made that decision in the moment instead of in February when you had time to think.

This is the most common pattern I see in PNW kitchen gardens. The garden itself is fine. The beds are in, the soil is decent, someone bought seeds. What is missing is the plan that connects all of it: what goes in the ground when, what follows it, and whether the space actually works for the crops the household wants to eat.

That gap is not a motivation problem. It is a structure problem. And it is exactly why PNW garden planning needs to happen before you are standing in the garden wondering what to do next.

Why PNW Garden Planning Is Different

My Seattle garden in April. Cool-season crops are in and going strong: lettuce, brassicas, onions all sharing the same bed. The summer beds are still waiting. Knowing which window belongs to which crop is the whole game.

Most gardening guides are written for climates that do not look like Seattle. Seed packets assume a last frost date and a growing season that lines up with the Midwest or the Northeast. They are not wrong for those places. They are just useless here.

Zone 8 through 9a in the Pacific Northwest has a cool, wet spring that lasts longer than most people expect, a dry summer with very little rain from July through September, and a fall window that is genuinely productive if you plan for it. Cool-season crops like kale, chard, lettuce, peas, or brassicas have a long runway if you start at the right time. Warm-season crops need to go in after conditions actually stabilize, which in Seattle is later than people new to this region often assume.

The result is that generic planting calendars send people in the wrong direction. They plant tomatoes too early, get surprised by the June gloom, and then wonder why everything feels behind. Or they miss the fall planting window entirely because they were not thinking that far ahead in August.

The planning question nobody answers

This is how I actually plan a new children's kitchen garden: crops, spacing, and what fits before a single seed goes in the ground.

Here is the thing that most kitchen garden content does not address: how many plants do you actually need?

You can know exactly when to plant and still end up with either too much of the wrong thing or not enough of what you actually eat. I see this constantly. Someone plants three zucchini because they had the space. By August, they are leaving bags on neighbors' doorsteps. Someone else plants two tomato plants and wonders why they still buy most of their tomatoes at the store in September.

The yield question - how many plants you need to produce a specific amount of food for your household - is the piece that requires its own calculation. It depends on your family size, how often you want to eat a specific crop, how many growing cycles that crop gets in one season, and whether your available bed space can actually support it.

Figuring this out by hand is not complicated, but it requires sitting down and doing the math before you order seeds or start your seedlings.

What planning ahead actually changes

This is what a planned bed looks like in late April. Kale, radishes, onions, and carrots all timed to be in the ground together - not because it happened accidentally, but because the season was mapped out before the first seed went in.

When you plan in February instead of April, you stop making reactive decisions. You know what is going in the ground this week because you worked it out when you had time to think. You know whether your four-by-eight bed can realistically support your lettuce habit or whether you need to add another row. You know when the garlic comes out so you can put the summer squash in that spot.

That is it. There is no magic. Just a clear picture of your zone, your crops, and your season... worked out before the season gets busy.

How I built the PNW Harvest Yield Planner

I built the PNW Harvest Yield Planner because this calculation "...how many plants for how much food?" was the one thing I could not find a clean answer to when I was setting up my own beds. It covers 59 PNW-friendly crops, sorted by family, with difficulty ratings, seasonal timing, and yield data based on actual Pacific Northwest growing conditions. You put in your household size and how often you want to eat a crop, and it tells you how many plants you need and whether your available space can support it.

If your spring planting still feels reactive, this is where I would start:
