Ensuring a moist, nutrient-dense environment is key to the plant’s success, and with attentive care post-harvest, many varieties will continue to produce secondary shoots.

However, attention must be paid to pests such as aphids and cabbage worms. Selecting compact varieties, like Small Miracles, can benefit those with limited space, yielding a substantial main head and additional shoots. Effective pest management, along with the right variety selection and attention to spacing and drainage, is critical for flourishing broccoli plants.

Cabbage

Cabbage

Cabbage, much like broccoli, favors cooler weather, and high temperatures can cause the heads to split. This vegetable demands a high nitrogen content in the soil to support its growth and maintain leaf moisture. Facing similar challenges as other members of the brassica family, cabbage is particularly prone to slug attacks, making effective pest control essential.

With a wide range of varieties including red, green, and different textures such as Savoy and Chinese cabbages, each requires specific attention to thrive. Adhering to planting guides, coupled with regular watering and diligent pest management, plays a critical role in nurturing robust cabbage plants, ensuring they grow healthily and produce abundantly.

Carrots

Carrots

Carrots demand specific soil conditions for optimal growth, with heavy soils necessitating the choice of shorter varieties and well-drained, deep soils—achievable through raised beds—being ideal for longer types. The success of growing carrots, from compact Chantenay to long Imperator varieties, hinges on selecting the right type for your soil condition and maintaining soil moisture, with options even for baby carrots in containers or poor soil, ensuring a fruitful harvest.

Beets

Beets

Beets flourish in our climate, showing great resilience against pests and diseases, and can be grown directly from seeds or as transplants, though early transplantation is key. They require consistent watering to develop strong roots and are valued both for their historical use as a natural dye and for their nutritional benefits, offering edible roots and leaves without major pest or disease concerns. While open-pollinated varieties introduce diversity, beets need soil with a pH above 6 and a careful addition of boron to compensate for natural deficiencies, emphasizing the balance required in its application to avoid toxicity.

Peas

Peas

Oregon State University has introduced varieties of shell, sugar pod, and snap peas that are well-suited to our region’s diverse climates, with the caveat that they need protection from wind. To ensure a steady supply of peas, staggered planting from late winter through midsummer is advised, alongside the construction of supports like strings and stakes to prevent issues related to pests, diseases, and soil contamination. While newer pea varieties show resistance to common problems like aphids and powdery mildew, ongoing vigilance for pests and ensuring good air circulation remain important for healthy crops.

Potatoes

Potatoes

Potatoes, favoring light, sandy soils, excel in both coastal and varied climates, needing only moderate fertilizer and water; they showcase a spectrum of skin and flesh hues, including butter-like yellows, with types ranging from fingerlings to larger varieties each tailored for specific culinary applications such as baking or mashing. To prevent scab disease, it’s recommended to keep the soil slightly acidic and avoid lime, although scab-affected potatoes remain consumable.

Despite their lack of frost resistance, potatoes can recover from frost damage, yet early planting followed by overwatering or overfertilization might cause hollow heart, a condition with a noticeable void inside the potato. Pest management is crucial, as flea beetles and wireworms pose significant threats, necessitating the use of insecticides for the former and diligent efforts to detect and address the latter to maintain potato quality.

Brussels Sprouts

Brussels Sprouts

The Pacific Northwest’s moist and mild climate provides the perfect setting for Brussels sprouts, a vegetable that flourishes in cooler conditions, allowing for a slow growth process that enhances their sweet and nutty flavor. As a member of the cabbage family, Brussels sprouts grow on a thick stalk with small, leafy green buds forming in a spiral, each resembling a miniature cabbage, benefiting from the region’s consistent moisture and cool temperatures for optimal development.

Cauliflower

Cauliflower

Cauliflower, known for its preference for cooler climates like those in the Pacific Northwest, is the most temperamental of the brassica family and prone to boron deficiency and “buttoning,” where abrupt temperature shifts lead to underdeveloped heads. While available in a variety of colors beyond the traditional white, including green, yellow, and purple, cauliflower attracts pests such as root maggots, cabbage worms, and slugs, necessitating careful monitoring and potential use of paper collars or insecticides for successful growth.

Spinach

Spinach

The Pacific Northwest’s cool, moist climate, complemented by well-draining, fertile soil, creates an optimal growing environment for spinach, a leafy green that matures in 4 to 6 weeks and is particularly well-suited to the region. Spinach, which comes in savoy, semi-savoy, and flat-leaf varieties, is rich in oxalates and antioxidants like lutein and zeaxanthin, offering significant health benefits despite the potential for reduced calcium absorption.

Onions

Onions

Onions, favoring full sunlight and light, organically rich soil, grow best from seeds due to less disease susceptibility and a wider variety choice, offering larger bulbs and simpler cultivation by sowing in deep pots for robust roots. In the Pacific Northwest, long-day onions are preferred, complemented by emerging day-neutral hybrids for their size and independence from day length; attention to weed and pest control, specifically onion maggots, and proper watering and curing techniques are vital for successful cultivation and storage.

Garlic

Garlic

Garlic cultivation is efficient due to its clonal propagation, with two primary types: soft neck, which is common in stores and has multiple layers of cloves, and hard neck, known for its large cloves and a central stalk that should be removed to boost bulb growth. Planting is best in October in well-drained, limed soil, spacing bulbs 5 inches apart for a summer harvest; after June, cease watering to prevent clove wrapper splitting, and harvest when leaves yellow. Curing involves hanging the garlic in a warm, dry place before storing in a cool, dark location, avoiding refrigeration to prevent sprouting.

Radishes

Radishes

The mild climate and consistent moisture of the region are ideal for radishes, enabling them to grow quickly while retaining their crispness and flavor, which is perfect for the local environment.
