Additional Considerations

Continue to Water Appropriately

One of the most critical factors in ensuring the survival of plants in containers during winter is proper watering. While it may be tempting to reduce watering during the colder months, it is essential to continue to provide adequate moisture to the soil. Over-wintering plants in containers are more susceptible to drying out, as the cold weather can cause the soil to retain less moisture.

It is recommended to water the plants in the morning, as this will allow the soil to dry out before nightfall, reducing the risk of root rot. It is also essential to use a well-draining soil mix, as poor drainage can lead to the accumulation of excess water in the soil, which can be detrimental to the plant’s health.

Adjust Fertilization Schedule

Fertilizing container plants during the winter months can be a bit more complicated than during the growing season. Over-wintering plants typically require less fertilizer, as they are not actively growing. However, it is still important to provide some nutrients to the plants to support their health and survival.

A good rule of thumb is to reduce the frequency of fertilization during the winter months, but maintain the same level of nutrients. This can be achieved by using a slow-release fertilizer, which will provide the necessary nutrients over an extended period of time. Alternatively, it is possible to continue fertilizing the plants on a reduced schedule, adjusting the amount of fertilizer used to account for the reduced growth rate of the plants.

Provide Adequate Light

Light is a crucial factor in the survival of container plants during the winter months. While the reduced level of sunlight during the winter may not be sufficient for the growth of many plants, it is still essential to provide adequate light to support their health and survival.

Container plants should be placed in a location where they receive indirect sunlight, such as near a south-facing window. It is also possible to use grow lights to supplement the light provided by natural sunlight, particularly during the shorter days of winter. The use of grow lights can also help to regulate the light levels, ensuring that the plants receive the appropriate amount of light for their needs.
