Introduction
Tree collards, often overshadowed by their more common relatives like kale and collard greens, are a remarkable addition to any garden. Known for their impressive size, nutritional benefits, and resilience, tree collards can be a staple in your vegetable garden. Whether you’re a seasoned gardener or a beginner, this guide will walk you through the steps to successfully grow and care for tree collards, ensuring a robust and productive harvest.
Choosing the Right Variety
When starting your journey with tree collards, selecting the right variety is crucial. Popular choices include ‘Tennessee Tree Collard,’ known for its hardiness and large, dark green leaves, and ‘Purple Tree Collard,’ which offers a striking purple hue and similar growth characteristics. Both varieties are well-suited for a range of climates, but it’s essential to choose one that fits your local conditions. Researching the specific needs and characteristics of each variety will help ensure success.
Soil Preparation
Tree collards thrive in well-drained, fertile soil with a pH level between 6.0 and 7.0. Start by testing your soil to determine its pH and nutrient levels. Amend your soil with organic matter, such as compost or well-rotted manure, to enhance its fertility and drainage capabilities. A rich, loamy soil provides the ideal environment for tree collards to establish strong root systems and achieve vigorous growth.
Planting
You can start tree collards from seeds or purchase young plants from a nursery. If starting from seeds, sow them indoors 6-8 weeks before the last expected frost date. Use seed trays or pots filled with seed-starting mix. Keep the soil consistently moist and provide adequate light to ensure strong seedling development.
When the seedlings are large enough to handle and the outdoor conditions are favorable, transplant them into your garden. Space the plants 24-36 inches apart to accommodate their large size and allow for proper air circulation. If you’re using young plants from a nursery, follow the same spacing guidelines and plant them at the same depth they were growing in their pots.
Watering
Tree collards require consistent moisture to thrive. Water the plants deeply and regularly, particularly during dry spells, to ensure that the soil remains consistently moist but not waterlogged. Overwatering can lead to root rot, so it’s essential to monitor soil moisture and adjust your watering practices as needed. Drip irrigation or soaker hoses can be effective for providing consistent moisture while reducing water waste.
Fertilization
Fertilizing your tree collards is important for maintaining healthy growth and productivity. Apply a balanced, all-purpose fertilizer every 4-6 weeks during the growing season. Follow the manufacturer’s instructions for application rates to avoid over-fertilization, which can harm the plants. Additionally, you can use organic options like compost tea or fish emulsion to provide essential nutrients.
Pest and Disease Management
While tree collards are relatively resilient, they are not immune to pests and diseases. Common pests include aphids, caterpillars, and leaf miners. Regularly inspect your plants for signs of infestation and take appropriate action if necessary. Organic treatments, such as neem oil or insecticidal soap, can be effective for controlling pests without harming beneficial insects.
Fungal diseases, such as downy mildew or powdery mildew, can also affect tree collards. To prevent these issues, ensure good air circulation around your plants by spacing them adequately. Remove any infected plant material promptly and avoid overhead watering, which can promote fungal growth. If diseases become a problem, consider using organic fungicides or adjusting your garden practices to improve plant health.
Harvesting
One of the advantages of tree collards is their extended harvest period. Begin harvesting leaves when they are 8-12 inches long. Start by picking the outer leaves, which allows the inner leaves to continue growing. Tree collards are a cut-and-come-again plant, meaning you can continuously harvest leaves throughout the growing season. The leaves are best used fresh but can also be stored in the refrigerator for several days.
Winter Care
In colder climates, tree collards can survive through the winter with some protection. Mulch around the base of the plants with straw or leaves to insulate the roots and prevent frost damage. In areas with severe winters, consider using row covers or cold frames to provide additional protection. This approach will help your tree collards endure the winter and continue producing fresh greens in the spring.
