How To Grow Broccoli Raab from Seed

Understanding Broccoli Raab

Broccoli Raab Basics

Broccoli raab, also known as rapini, is a leafy green vegetable that is a member of the Brassica family. While it is often referred to as broccoli, it is actually more closely related to turnips. Broccoli raab has a slightly bitter taste and is commonly used in Italian and Chinese cuisine. It is a cool-season crop that can be grown in both the spring and fall.

Broccoli raab is a fast-growing plant that can reach maturity in as little as 40 days. It is a hardy plant that can grow in a variety of soil types, but it prefers well-draining soil that is rich in organic matter. Broccoli raab also requires full sun and regular watering to thrive.

Seed Selection

When selecting broccoli raab seeds, it is important to choose a variety that is suited to your growing conditions. Some popular varieties of broccoli raab include:

  • Super Rapini: This early Italian heirloom matures in just 60 days and produces a large amount of leaves all at once.
  • Spring Raab: This variety is a good choice for spring planting and produces tender, sweet leaves.
  • Cima di Rapa: This variety is popular in Italy and produces large, tender leaves and small broccoli-like heads.

When planting broccoli raab seeds, it is important to follow the instructions on the seed packet. Broccoli raab can be direct-seeded or transplanted, depending on your preference. Direct-seeding is typically done in early spring or late summer, while transplanting is done in the early spring. Broccoli raab seeds should be planted in rows that are 18 inches apart, and the plants should be thinned to 6 inches apart once they have sprouted.

In summary, broccoli raab is a fast-growing leafy green vegetable that is a member of the Brassica family. It is a cool-season crop that can be grown in both the spring and fall. When selecting broccoli raab seeds, it is important to choose a variety that is suited to your growing conditions. Direct-seeding and transplanting are both viable options for planting broccoli raab seeds.

Preparing the Soil

Before planting broccoli raab, it is important to prepare the soil properly. Here are some steps to follow:

  1. Choose a sunny spot: Broccoli raab needs at least 6 hours of direct sunlight per day to grow properly. Choose a spot in your garden that gets plenty of sun.

  2. Test the soil: Broccoli raab prefers a slightly acidic soil with a pH between 6.0 and 7.0. You can test your soil using a soil testing kit, which you can buy at a garden center or online.

  3. Amend the soil: If your soil is too acidic, you can add lime to raise the pH. If it is too alkaline, you can add sulfur to lower the pH. You can also add compost or well-rotted manure to improve the soil’s fertility and texture.

  4. Remove weeds and debris: Clear the area of any weeds, rocks, or debris that could interfere with the growth of your broccoli raab.

  5. Loosen the soil: Use a garden fork or tiller to loosen the soil to a depth of at least 6 inches. This will help the roots of your broccoli raab to grow deep and strong.

  6. Add fertilizer: Before planting, you can add a balanced fertilizer to the soil to provide your broccoli raab with the nutrients it needs to grow. Follow the instructions on the fertilizer package for the amount to use.

By following these steps, you can prepare your soil for planting broccoli raab from seed.

Planting the Seeds

When it comes to planting broccoli raab from seed, there are a few key factors to keep in mind. In this section, we’ll cover the sowing technique and optimal conditions for planting your seeds.

Sowing Technique

Broccoli raab can be sown directly into the ground or started indoors and transplanted outside. If you choose to sow directly, make sure the soil is well-draining and has a pH between 6.0 and 7.0. Sow the seeds about 1/4 inch deep and 1 inch apart, then cover with soil and water gently.

If you prefer to start your seeds indoors, sow them in a seed-starting mix about 6-8 weeks before the last expected frost in your area. Once the seedlings have grown to about 2-3 inches tall, they can be transplanted outside. Make sure to harden off the seedlings by gradually exposing them to outdoor conditions over the course of a week before transplanting.

Optimal Conditions

Broccoli raab grows best in cool weather, so it’s important to plant your seeds at the right time. In most areas, you can plant broccoli raab in the spring or fall. If planting in the spring, wait until the soil has warmed up to at least 50°F before sowing your seeds. In the fall, sow your seeds about 6-8 weeks before the first expected frost in your area.

Broccoli raab also prefers full sun but can tolerate some shade. Make sure to keep the soil consistently moist but not waterlogged. Adding a layer of mulch around your plants can help retain moisture and regulate soil temperature.

Overall, broccoli raab is a relatively easy vegetable to grow from seed as long as you provide the right conditions. By following these tips for sowing and optimal conditions, you’ll be on your way to a successful broccoli raab harvest.

Broccoli Raab Care

Growing broccoli raab from seed is relatively easy, but proper care is essential to ensure a healthy and productive harvest. Here are some tips for caring for your broccoli raab plants:

Watering Requirements

Broccoli raab plants need consistent moisture to thrive. Water your plants deeply once or twice a week, depending on weather conditions and soil type. Be sure to water at the base of the plant to avoid getting the leaves wet, which can lead to disease. Mulching around the base of the plant can help retain moisture and regulate soil temperature.

Fertilizing Needs

Broccoli raab plants are heavy feeders and require regular fertilization to produce a healthy crop. Before planting, amend the soil with compost or well-rotted manure to provide essential nutrients. Once the plants have established, fertilize every two weeks with a balanced fertilizer, such as a 10-10-10 or 20-20-20 blend. Be sure to follow the manufacturer’s instructions for application rates and methods.

By following these simple care tips, you can enjoy a bountiful harvest of delicious broccoli raab.

Harvesting and Storage

When your broccoli raab plants are about 6-15 inches tall and the flower buds are still unopened, it is time to start harvesting. Cut the raab near the soil level or at the lowest point that the stem is still tender. Usually, the top 6-8 inches of stem is cut.

It is important to harvest the raab promptly because the flowers will open quickly and the leaves will become bitter. You can harvest the plants multiple times, cutting the stems at different heights to allow for regrowth.

After harvesting, it is best to use the raab immediately, but it can be stored in the refrigerator for up to a week. To store, wrap the raab in a damp paper towel and place it in a plastic bag.

If you want to save seeds from your broccoli raab plants, let the flowers bloom and then dry out on the plant. The seed pods will turn brown and can be harvested by cutting the stem below the pods. Store the pods in a paper bag until they are completely dry, then remove the seeds and store them in a cool, dry place.

Remember to always wash your hands and tools before and after harvesting to prevent the spread of disease.
