When it comes to gardening in the Pacific Northwest, timing is everything. You want to make sure your plants have the best chance of thriving, and that means planting during the optimal times. Here's a month-by-month planting calendar for Washington State:

A Month-by-Month Planting Calendar for Washington State

January: While the weather may be a bit chilly, there are still plenty of cold-hardy vegetables and flowers that you can plant. Think kale, winter cabbage, and pansies to add a pop of color to your winter garden.

February: Ah, February—the month of love and the perfect time to start sowing seeds indoors. Get a head start on your summer crops by planting tomatoes, peppers, and eggplants in pots or trays. This is also a great time to start planning your garden layout for the upcoming season. Consider the amount of sunlight each area of your garden receives and the type of soil you have. These factors will play a crucial role in determining which plants will thrive in different areas of your garden.

March: Spring has sprung in Washington State, and it's time to get your hands dirty. This is the month when gardening truly comes alive, so here's what you need to know:

March is the perfect time to start planting cool-season vegetables like lettuce, spinach, and radishes. These crops thrive in the cooler temperatures and can tolerate a light frost. It's also a good time to plant perennial flowers such as daffodils, tulips, and crocuses. These early bloomers will add a burst of color to your garden and signal the arrival of spring.

April: As the days grow longer and the temperatures rise, April is a busy month for gardeners in Washington State. This is the time to plant warm-season vegetables like tomatoes, peppers, cucumbers, and squash. It's also a great time to start planting annual flowers such as marigolds, petunias, and zinnias. These plants will thrive in the warmer weather and add beauty to your garden throughout the summer months.

May: By May, the threat of frost has passed, and it's safe to plant tender annuals and vegetables outdoors. This is the month to plant heat-loving crops like beans, corn, melons, and pumpkins. It's also a good time to start planting herbs such as basil, cilantro, and dill. These herbs will not only add flavor to your meals but also attract beneficial insects to your garden.

June: With the arrival of summer, June is a time of abundant growth in Washington State gardens. This is the month to focus on maintaining your garden by watering regularly, mulching to conserve moisture, and keeping an eye out for pests and diseases. It's also a good time to start harvesting early crops like lettuce, peas, and strawberries. Enjoy the fruits of your labor and savor the taste of freshly picked produce.

July: As the temperatures soar, July can be a challenging month for gardeners in Washington State. It's important to provide your plants with adequate water and shade to help them beat the heat. This is also a good time to plant fall crops such as broccoli, cauliflower, and carrots. These cool-season vegetables will mature in the cooler temperatures of autumn and provide you with a bountiful harvest.

August: August is a transitional month in Washington State gardens. While the summer crops are still producing, it's time to start thinking about the fall garden. This is the month to plant cool-season greens like lettuce, kale, and Swiss chard. These leafy greens will thrive in the cooler temperatures of fall and provide you with fresh, nutritious salads.

September: As summer comes to an end, September is a time of harvest and preparation for the winter months. This is the month to harvest your remaining summer crops and start planting cover crops like clover and rye. These cover crops will help improve the soil fertility and prevent erosion during the winter months. It's also a good time to start cleaning up your garden and preparing it for the next growing season.

October: With the arrival of fall, October is a beautiful time to be in the garden. This is the month to plant spring-blooming bulbs like tulips, daffodils, and hyacinths. These bulbs will lie dormant throughout the winter months and burst into colorful blooms in the spring. It's also a good time to start planting garlic, which will overwinter and be ready for harvest in the following summer.

November: As the days grow shorter and the temperatures drop, November is a quieter month in Washington State gardens. This is the time to focus on garden cleanup, removing dead plants, and adding compost to the soil. It's also a good time to start planning for next year's garden. Take note of what worked well this year and what didn't, and make adjustments to your garden plan accordingly.

December: As the year comes to a close, December is a time of rest and reflection in the garden. This is the month to enjoy the beauty of your winter garden, with evergreen trees and shrubs providing structure and color. It's also a good time to start dreaming and planning for the next gardening season. Browse seed catalogs, research new varieties, and envision the possibilities for your garden in the coming year.
