How do you overwinter new plants?

Overwintering new plants is an important task to ensure their survival and growth in the following seasons. To successfully overwinter new plants, it is essential to remove any debris and loose soil from around the plant. This helps to prevent the buildup of pests and diseases that could harm the plant during the winter months.

Once the plant has been cleaned, it is advisable to store them in trays filled with sand, coir, or vermiculite. These materials provide a suitable environment for the plants to remain dormant during the winter. The trays should be deep enough to accommodate the entire root system of the plant, with the crown (where the stems join the roots) just showing above the surface.

To store the plants, place them gently into the trays, ensuring that the roots are covered by the sand, coir, or vermiculite. It is important not to bury the crown of the plant, as this could lead to rotting or other damage. The trays should then be placed in a cold, frost-free greenhouse or conservatory.

During the winter months, it is crucial to keep the stored plants just moist. This can be achieved by regularly checking the moisture level and watering as needed. It is important not to overwater the plants, as this can lead to rotting. Conversely, allowing the plants to dry out completely can also be detrimental.

For container-grown plants, they can be stored in their pots after cutting back. This involves pruning the plant to remove any dead or damaged growth. Cutting back not only helps to maintain the plant’s shape but also reduces the risk of pests and diseases overwintering on the plant.

Once the plants have been cut back, they can be stored in a frost-free area such as a garage or shed. It is important to ensure that the plants are protected from extreme temperatures and frost. Wrapping the pots with bubble wrap or hessian can provide additional insulation.

In addition to these general guidelines, it is important to consider the specific needs of each plant species. Some plants may require additional protection, such as wrapping with fleece or straw, to survive the winter. Researching the specific requirements of the plants you are overwintering can help ensure their successful survival.

Overwintering new plants involves removing debris and loose soil, storing them in trays with the crown just showing, keeping them just moist, and providing protection from extreme temperatures and frost. By following these steps and considering the specific needs of each plant, you can help ensure the survival and growth of your new plants in the following seasons.
