Whether you’re a seasoned gardener or just starting out, this guide will help you decide what to plant now to make the most of Portland’s unique growing conditions.
Portland’s USDA Hardiness Zone is 8b, which means you can grow a diverse range of plants, from cool-season vegetables to heat-loving perennials. The key to successful gardening in Portland is understanding the city’s microclimates and choosing plants that thrive in your specific area. Let’s dive into the best plants to plant now in Portland, Oregon.
Cool-Season Crops
Portland’s cool, wet spring is perfect for growing cool-season crops. These plants prefer temperatures between 40-65°F (4-18°C) and can tolerate light frosts. Plant them now for a bountiful harvest in late spring and early summer.
Cool-season crops are also great for improving soil health and preventing weeds. They help to break up compacted soil, add organic matter, and suppress weed growth. Here are some cool-season crops to consider planting now:
Vegetables
Vegetables like lettuce, spinach, kale, and Swiss chard are excellent choices for Portland’s cool spring. They grow quickly and can be harvested in as little as 45 days. Plant them in full sun to partial shade, and keep the soil consistently moist but not waterlogged.
Other cool-season vegetables to consider include radishes, turnips, beets, and peas. These crops are relatively easy to grow and can be harvested within a few weeks of planting. To extend your harvest, consider succession planting, where you plant a new crop every two weeks to ensure a continuous supply of fresh produce.
Flowers
Cool-season flowers can add a pop of color to your garden and attract beneficial pollinators. Consider planting flowers like pansies, violas, primroses, and calendulas. These flowers are tough and can tolerate cooler temperatures, making them perfect for Portland’s spring weather.
For a continuous bloom, consider planting a mix of early and late-blooming flowers. This will ensure that your garden is in full color from early spring until the first frost. Additionally, many cool-season flowers are edible, making them a great choice for gardeners who want to incorporate flowers into their meals.
Warm-Season Crops
While Portland’s cool spring is perfect for growing cool-season crops, the city’s mild summers are ideal for warm-season crops. These plants prefer temperatures between 65-85°F (18-29°C) and can be planted once the danger of frost has passed, typically in late April or early May.
Warm-season crops are great for adding structure and height to your garden. They also provide habitat and food for beneficial insects and wildlife. Here are some warm-season crops to consider planting now:
Vegetables
Warm-season vegetables like tomatoes, peppers, eggplant, and cucumbers are staples in Portland gardens. These plants require full sun and well-draining soil to thrive. Consider planting them in raised beds or containers to improve drainage and prevent rot.
Other warm-season vegetables to consider include beans, squash, and corn. These crops are relatively easy to grow and can be harvested in late summer and early fall. To extend your harvest, consider succession planting, where you plant a new crop every two weeks to ensure a continuous supply of fresh produce.
Flowers
Warm-season flowers can add a vibrant pop of color to your garden and attract beneficial pollinators. Consider planting flowers like marigolds, zinnia, cosmos, and black-eyed Susans. These flowers are tough and can tolerate warmer temperatures, making them perfect for Portland’s summer weather.
For a continuous bloom, consider planting a mix of early and late-blooming flowers. This will ensure that your garden is in full color from early summer until the first frost.
