What is Tenderstem Broccoli?
Tenderstem broccoli, also known as broccolini or asparabroc, is a hybrid vegetable that is a cross between Chinese broccoli and conventional broccoli. It is characterized by its long, slender stems and small, tender florets. Tenderstem is prized not only for its unique taste but also for its nutritional benefits, including vitamins C and K, as well as fiber and antioxidants.
Selecting the Right Variety
While the most commonly known variety is just “tenderstem,” there are other hybrids worth exploring. Some may have minor differences in flavor or crop time. Be sure to select disease-resistant varieties from reputable seed suppliers or nurseries.
Tips for Seed Selection:
- Choose certified organic seeds when possible, as they typically yield healthier plants.
- Check the seed packet for growth duration; Tenderstem usually matures in around 80 to 100 days.
Soil Preparation
1. Soil Type
Tenderstem broccoli thrives in well-draining, fertile soil with a pH between 6.0 and 7.0. A loamy soil enriched with organic matter is ideal, as it retains moisture while providing nutrients.
2. Enhancing Soil
Prepare your garden bed by:
- Clearing Debris: Remove any weeds, rocks, or old plant material.
- Adding Organic Matter: Incorporate well-rotted manure, compost, or leaf mold into the soil.
- Testing pH: Use a soil testing kit to check the pH and make necessary adjustments with lime or sulfur.
Planting Tenderstem Broccoli
1. Timing
Tenderstem broccoli can be planted in spring or late summer for a fall harvest. In most climates, aiming for a spring planting around late March to early April is optimal.
2. Sowing Seeds
You can directly sow seeds into the ground or start them indoors:
- Direct Sowing: Plant seeds ½ inch deep and 12 inches apart. Rows should be spaced about 18 inches apart.
- Indoor Planting: Start seeds indoors about 4–6 weeks before the last frost. Transplant them outdoors once they are at least 3–4 inches tall and hardened off.
3. Transplanting Seedlings
If you’ve started seedlings indoors, transplant them after hardening off—this means gradually exposing them to outdoor conditions over a week. Plant them at a depth similar to their original pot.
Care for Tenderstem Broccoli
1. Watering
Tenderstem broccoli requires consistent moisture, particularly during its growing period. Here are some aspects of effective watering:
- Frequency: Water deeply once a week, more often in hot and dry conditions.
- Mulching: Apply a 2–3 inch layer of mulch around the plants to retain moisture and suppress weeds.
2. Fertilizing
Fertilizing will help you achieve robust growth and maximum yields:
- Type of Fertilizer: Use a balanced fertilizer high in nitrogen during the early growth stage. After 4–6 weeks, switch to a phosphorus-rich fertilizer to promote flowering.
- Application: Follow package instructions, usually applying every 4–6 weeks.
3. Pest and Disease Management
Common pests and diseases include aphids, cabbage worms, and downy mildew.
- Organic Pest Control: Introduce beneficial insects like ladybugs and use neem oil or insecticidal soap to manage pests.
- Preventive Measures: Practice crop rotation to minimize disease risk and apply row covers to deter pests.
4. Spacing
Proper spacing allows air circulation, reducing the risk of diseases. Maintain at least 12 inches between plants to ensure good airflow.
Harvesting Tenderstem Broccoli
1. Timing for Harvest
Tenderstem broccoli is typically ready for harvest within 80 to 100 days after planting. The key indicators for harvesting include:
- Size: Stalks should be about 5-7 inches long.
- Florets: Keep an eye on the buds; they should be tight and not yet flowering.
2. Harvesting Technique
- Cutting: Use a sharp knife or scissors to cut the stalk just below the floret. Be sure to leave a few leaves on the plant to encourage further growth.
3. Post-Harvest Care
After harvesting, rinse the broccoli in cold water and store it in the refrigerator in a sealed container. Freshly harvested tenderstem can typically last for up to a week.
Tips for Maximizing Your Harvest
- Succession Planting: To ensure a continuous supply, consider sowing seeds in two-week intervals.
- Companion Planting: Use companion plants like carrots or radishes to improve your garden’s overall health and productivity.
- Regular Monitoring: Keep an eye on moisture levels and pests. Frequent checks will help you catch any issues before they escalate.
