If you’re a broccoli lover living in Oregon, you’re in luck! The moderate climate and fertile soil in Oregon make it an ideal place to grow Calabrese broccoli. In this article, we will explore everything you need to know about when to plant and how to grow this delicious vegetable in the Beaver State.
Climate & Hardiness Zones in Oregon
Before we dive into the details of growing Calabrese broccoli, it’s essential to understand the climate and hardiness zones in Oregon. The state is known for its diverse climate, ranging from coastal regions with cool summers to the high desert with hot, dry summers.
Oregon is divided into USDA hardiness zones 4 to 9, with zone 4 being the coldest and zone 9 being the warmest. Coastal areas usually fall into zones 7 to 9, while the eastern part of the state falls into zones 4 to 7. Understanding your specific hardiness zone will help you determine the best time to plant Calabrese broccoli.
Zone 4 in Oregon covers the coldest regions of the state, such as the higher elevations of the Cascade Range and the Blue Mountains. These areas experience long, cold winters with temperatures dropping below freezing for extended periods. Gardeners in Zone 4 need to select cold-hardy vegetable varieties like kale, carrots, and Brussels sprouts to ensure a successful harvest.
On the other hand, Zone 9 in Oregon includes the warmest regions, such as the Rogue Valley and parts of the Willamette Valley. These areas enjoy mild winters and hot summers, creating ideal conditions for heat-loving crops like tomatoes, peppers, and eggplants. Gardeners in Zone 9 can take advantage of the long growing season to cultivate a wide range of vegetables and fruits.
When to Plant Calabrese Broccoli in Oregon
The timing of planting Calabrese broccoli largely depends on the average temperatures during different seasons in your specific location.
Generally, it is recommended to start seeds indoors about six to eight weeks before the last frost date. The last frost date varies across Oregon, but for most areas, it falls between late March and early May. You can check the specific date for your region on the Farmers’ Almanac website or consult your local nursery.
To ensure successful growth and productivity, transplant your broccoli seedlings outdoors when they have four to six true leaves and no longer than ten weeks after sowing seeds indoors. This will give them a head start before the warmer weather arrives.
If you prefer direct seeding, you can sow the seeds in early spring or late summer, depending on your location and the length of your growing season. Make sure to provide the plants with enough water and cover them with row covers to protect them from unexpected late frosts during spring planting.
Calabrese broccoli, also known simply as broccoli, is a cool-season vegetable that thrives in Oregon’s climate. Known for its large, green flowering heads and tender stalks, Calabrese broccoli is a popular choice for home gardeners and commercial growers alike.
When selecting a planting location for your Calabrese broccoli, choose a spot that receives full sun for at least 6-8 hours a day. The soil should be well-draining, rich in organic matter, and slightly acidic with a pH between 6.0 and 7.0. Consider amending the soil with compost or well-rotted manure before planting to provide essential nutrients for healthy growth.
Broccoli is a heavy feeder, so it’s important to fertilize the plants regularly with a balanced fertilizer high in nitrogen. Water consistently to keep the soil evenly moist, especially during dry spells. Mulching around the plants can help retain soil moisture and suppress weed growth.
When to Harvest or Pick Calabrese Broccoli in Oregon
Harvesting Calabrese broccoli at the right time ensures the best flavor and texture. The maturity of the broccoli heads largely depends on the variety and growing conditions.
As a general rule, the heads are ready to harvest when they reach a compact size, have a deep green color, and the buds are still closed. If the buds start to open or turn yellow, it means that the heads are overripe and may taste bitter.
Depending on when you plant, you can expect your broccoli to mature in 70 to 100 days. Regularly monitor your plants, and harvest the heads when they meet the desired criteria. To harvest, use a sharp knife or pruning shears to cut the stalk below the head, leaving a few inches of stem attached.
Broccoli is a cool-season crop that thrives in Oregon’s climate, particularly in the Willamette Valley and other regions with similar conditions. The state’s moderate temperatures and ample rainfall provide an ideal environment for growing this nutritious vegetable. When planting Calabrese broccoli in Oregon, it’s essential to consider the local frost dates to ensure a successful harvest.
In addition to monitoring the appearance of the broccoli heads, pay attention to the overall health of the plant. Look out for any signs of pests or diseases, such as aphids or powdery mildew, which can impact the quality of the harvest. Proper spacing between plants, adequate sunlight, and regular watering are key factors in cultivating robust broccoli plants in Oregon’s diverse microclimates.
Frequently Asked Questions
In this section, we will address some commonly asked questions about planting and growing Calabrese broccoli in Oregon.
Q: Can I grow Calabrese broccoli in containers?
A: Yes, you can grow Calabrese broccoli in containers as long as the containers are at least 12 inches deep and have drainage holes. Choose a compact or dwarf variety and provide adequate sunlight, water, and nutrients to support their growth.
Q: How often should I water my Calabrese broccoli plants?

Q: Are there any common pests or diseases that affect Calabrese broccoli?
A: Yes, Calabrese broccoli can be prone to pests such as aphids, cabbage worms, and cabbage loopers. It is also susceptible to diseases like clubroot and blackleg. To prevent infestations and diseases, practice crop rotation, use organic pest control methods, and provide adequate spacing between plants for good airflow.
Q: Can I save seeds from Calabrese broccoli for future planting?
A: Absolutely! Calabrese broccoli is an open-pollinated variety, which means you can save the seeds from mature heads for future planting. Allow some of your plants to bolt and produce flowers. Once the flowers fade, the seed pods will develop. Harvest the pods when they turn brown, dry them thoroughly, and store them in a cool, dry place for next year’s planting.
Q: Are there any companion plants that are beneficial for Calabrese broccoli?
A: Yes, planting certain companion plants can help deter pests and improve the overall health of your Calabrese broccoli. Some common companion plants include marigolds, dill, and chamomile. These plants attract beneficial insects and help repel pests that can damage your broccoli.
Now that you have all the information you need, it’s time to roll up your sleeves and start growing delicious Calabrese broccoli in your Oregon garden. Enjoy the satisfaction of harvesting your own homegrown, nutritious veggies, and share your success stories with fellow gardeners!
When it comes to harvesting Calabrese broccoli, timing is key. The best time to harvest is when the central head is firm and tight, but before the individual flower buds start to open. Use a sharp knife or garden shears to cut the head off, leaving a few inches of stem attached. This will encourage side shoots to develop, giving you a continuous harvest throughout the season.
Once you’ve harvested your Calabrese broccoli, it’s important to store it properly to maintain its freshness. Place the heads in a plastic bag and store them in the refrigerator’s crisper drawer. They should stay fresh for up to a week. If you have an abundance of broccoli, you can blanch and freeze it for longer storage. Simply blanch the florets in boiling water for a few minutes, then transfer them to an ice bath to stop the cooking process. Drain well, pack into freezer bags or containers, and freeze for up to a year.
