Avoid letting the soil dry out completely, as this can stress the plant. Utilize a moisture meter or simply feel the soil with your fingers to gauge the moisture level. If the top inch of soil feels dry, it’s time to water. However, if the soil feels damp, hold off on watering until it dries out a bit. By adjusting watering schedules and monitoring soil moisture levels, you can help your hibiscus survive the winter months outside.

Fertilization Strategies For Winter

Hibiscus plants can survive winter outside with proper fertilization strategies. By providing the right nutrients and protecting the roots from freezing, you can help your hibiscus thrive through the colder months. Keep in mind the specific needs of your hibiscus variety and adjust your fertilization routine accordingly.

To Fertilize Or Not During Winter

When it comes to fertilizing your hibiscus plants during winter, it’s important to understand that their nutrient requirements change during dormancy. While some gardeners believe that fertilizing during winter is unnecessary, others swear by it.

The truth is, it depends on the specific needs of your hibiscus plant and the climate in which you live. If you live in a region with mild winters, your hibiscus may continue to grow and flower throughout the season. In this case, it’s a good idea to continue fertilizing as you would during the growing season.

However, if you live in an area with harsh winters, your hibiscus will likely go dormant. In this case, it’s best to hold off on fertilizing until the plant begins to show signs of new growth in the spring.

Nutrient Requirements During Dormancy

During dormancy, your hibiscus plant’s nutrient requirements change. While it still needs some nutrients to survive, it doesn’t need as much as it does during the growing season. In fact, over-fertilizing during dormancy can actually harm the plant.

To ensure that your hibiscus gets the nutrients it needs during dormancy, it’s important to choose a fertilizer with a low nitrogen content. Nitrogen encourages leafy growth, which is not necessary during dormancy. Instead, look for a fertilizer with a higher phosphorus content, as this will promote root growth and help your hibiscus store energy for the next growing season.

When fertilizing during dormancy, it’s important to follow the manufacturer’s instructions carefully. Over-fertilizing can damage the plant, so it’s better to err on the side of caution and use less fertilizer than recommended. Additionally, make sure to water your hibiscus well before and after fertilizing to prevent the roots from burning.

In conclusion, fertilizing your hibiscus during winter requires careful consideration of your plant’s specific needs and the climate in which you live. By choosing the right fertilizer and following the manufacturer’s instructions carefully, you can ensure that your hibiscus survives the winter and thrives in the spring.
