Heeling-in involves placing plants temporarily into a moist trench or soil to protect their roots while awaiting permanent planting, preserving moisture and root integrity. Potting-up means transferring plants into larger pots to encourage root development and provide a stable growing environment during temporary storage. Explore the detailed differences and benefits of heeling-in versus potting-up to determine the best method for your gardening needs.

Introduction to Temporary Plant Storage
Heeling-in and potting-up are essential techniques for temporary plant storage, promoting healthy root development and minimizing shock during transplantation. Heeling-in involves placing plants temporarily in trenches or soil beds to keep roots moist and protected, ideal during brief storage or transport. Potting-up requires transferring plants into larger pots with fresh soil, supporting root growth and ensuring vitality for longer storage periods.
What is Heeling-in?
Heeling-in is a horticultural technique used for the temporary storage of plants, especially bare-root seedlings, by partially burying their roots in soil or other moist medium to maintain hydration and prevent root desiccation. This method ensures optimal moisture retention and root protection, supporting plant viability until permanent planting can occur. Heeling-in is commonly applied in nurseries and during transportation phases to preserve plant health effectively.
What is Potting-up?
Potting-up is a method of temporary plant storage where a growing plant is transferred into a larger pot or container to promote root development and maintain plant health before permanent planting. This technique allows plants to continue growing in a controlled environment, preventing root binding and providing sufficient nutrients and water. Potting-up is particularly useful in nurseries and gardening when full planting is delayed due to weather or site preparation.
Key Differences Between Heeling-in and Potting-up
Heeling-in involves temporarily placing plants at an angle and covering their root systems with soil or mulch to maintain moisture, whereas potting-up entails transferring plants into larger pots to encourage root growth and stabilize the plant. Heeling-in is primarily used for short-term storage during transplanting or shipping, while potting-up supports longer-term growth and development in controlled environments. The choice between these methods depends on the plant species, duration of storage, and space availability.
When to Choose Heeling-in
Heeling-in is ideal for temporarily storing young plants or bare-root trees during transplantation when immediate potting is unavailable, especially in cool, shaded environments to prevent root desiccation. This method maintains root moisture and oxygen exchange by partially burying the root system in moist soil, ensuring plant survival during short-term holding periods. Choose heeling-in when plants need quick, temporary protection before permanent planting or potting can be done.
When to Opt for Potting-up
Potting-up is optimal when plants require more controlled conditions during temporary storage, such as consistent moisture and protection from pests or drastic temperature changes. This method is preferable for delicate or semi-mature plants that might suffer root damage or desiccation if left heeling-in outdoors. Nursery managers often choose potting-up for its ability to maintain plant health and facilitate easier transportation or sale within shorter timeframes.
Plant Types Suitable for Heeling-in
Heeling-in is ideal for woody plants, shrubs, and trees with established root systems that require temporary protection and moisture retention during transplanting. This method suits plants like evergreens, roses, and container-grown perennials that benefit from partial burial and consistent hydration to minimize root stress. Herbaceous plants and those with delicate root structures typically require potting-up to avoid damage and provide more controlled growth conditions.
Plant Types Suitable for Potting-up
Potting-up is ideal for a wide range of herbaceous perennials, seedlings, and young shrubs that require robust root development before permanent planting. Plants with delicate root systems and those intolerant to root disturbance, such as ferns and some alpine species, thrive when potted up instead of heeling-in. This method enables better nutrient control and reduces transplant shock, making it suitable for ornamental plants and container-grown vegetables.
Pros and Cons of Heeling-in vs Potting-up
Heeling-in offers a cost-effective and space-efficient method for temporary plant storage, allowing plants to be quickly buried in soil to maintain root moisture and health, though it can risk root damage if left too long or in unfavorable weather. Potting-up provides better control over soil quality and individual plant monitoring, reducing the risk of disease and root entanglement, but requires more time, space, and resources. Choosing between heeling-in and potting-up depends on factors like plant species, available space, budget, and the intended duration of storage.
Best Practices for Temporary Plant Storage
Heeling-in involves placing bare-root plants at an angle in a trench and covering their roots with soil to maintain moisture, making it ideal for short-term storage and transport. Potting-up requires transplanting seedlings or small plants into pots with soil, providing better root protection and easier handling but demands more space and care to prevent root disturbance. Both methods require consistent moisture, shade, and temperature control to ensure plant viability during temporary storage.
Important Terms
Bare-root storage
Heeling-in is preferred over potting-up for temporary bare-root storage as it maintains root moisture and minimizes transplant shock by partially burying plants in moist soil, while potting-up can cause root stress and is less suitable for short-term holding.
Root moisture retention
Heeling-in preserves root moisture effectively by maintaining soil contact and humidity around the roots, while potting-up may expose roots to drying due to less immediate soil insulation.
Transplant shock mitigation
Heeling-in temporarily reduces transplant shock by maintaining root moisture and stability, while potting-up offers longer-term growth support but may increase initial root disturbance during replanting.
Dormancy maintenance
Heeling-in preserves root dormancy during temporary plant storage by partially burying roots to maintain moisture and reduce stress, whereas potting-up can disrupt dormancy by promoting active growth through increased soil volume and nutrient availability.
Cold frame usage
Heeling-in involves temporarily placing bare-root plants in a shallow trench for cold frame storage to maintain root moisture, while potting-up uses individual pots filled with growing medium inside a cold frame for better root development and easier handling.
Media aeration
Heeling-in promotes superior media aeration by partially exposing plant roots to oxygen compared to potting-up, which confines roots within soil, potentially limiting oxygen availability during temporary storage.
Temporary root balling
Heeling-in provides temporary root balling by securing plants in a trench with moist soil to maintain root moisture, whereas potting-up involves transplanting into larger containers for short-term storage with enhanced root development.
Sphagnum moss packing
Heeling-in uses moist Sphagnum moss packing to temporarily store plants by partially burying roots in soil and moss to maintain hydration, whereas potting-up involves transferring plants into pots with Sphagnum moss to provide stable moisture retention and root protection.
Overwintering techniques
Potting-up provides controlled soil conditions and root protection ideal for overwintering tender plants, while heeling-in offers a temporary, space-efficient method shielding bare-root or dormant plants from frost damage during cold seasons.
Staging beds
Heeling-in provides a quick, temporary storage method for plants by partially burying roots in staging beds, enhancing moisture retention and root stability compared to potting-up which involves transplanting into pots for longer-term growth.
