Tender perennials, unlike hardy perennials, require special care in order to come back every year. While hardy perennials can withstand the harsh winter conditions and come back on their own, tender perennials are more sensitive to cold temperatures and need extra protection.
One important factor to consider is the climate in which you live. Tender perennials are typically native to warmer regions and may not be able to survive freezing temperatures. If you live in a colder climate, you may need to treat tender perennials as annuals, meaning you will need to replant them every year.
However, if you are determined to keep your tender perennials for multiple years, there are steps you can take to ensure their survival. The key is to protect them during the dormant period, which is usually during the winter months.
First, you will need to carefully dig up your tender perennials before the first frost hits. It’s important to do this before the ground becomes too hard or frozen. Be gentle when digging up the plants, making sure to preserve as much of the root system as possible.
Once you have dug up the plants, you will need to prepare them for storage. Start by trimming back any excess foliage or stems, as this will help reduce moisture loss during storage. Next, gently shake off any excess soil from the roots.
After cleaning the plant, you can choose one of several methods for storing tender perennials. One common method is to place them in pots or containers and store them in a cool, dark location such as a basement or garage. Make sure the temperature remains above freezing but is still cool enough to keep the plants dormant.
Another option is to store the plants in a dormant state in a refrigerator. This method works well for smaller tender perennials that can fit in plastic bags or containers. It’s important to keep them away from fruits and vegetables, as the ethylene gas they produce can harm the plants.
Regardless of the storage method you choose, it’s important to periodically check on your tender perennials during their dormant period. Inspect them for any signs of rot, mold, or pests. If you notice any issues, take appropriate action to address them.
In the spring, when the danger of frost has passed and the weather warms up, you can begin the process of reintroducing your tender perennials back into your garden. Gradually acclimate them to outdoor conditions by placing them in a sheltered area for a few hours each day, gradually increasing the amount of time they spend outside. This will help them adjust to the sunlight and temperature changes.
Once your tender perennials have been successfully reintroduced to the outdoors, continue to monitor them closely for any signs of stress or damage. Provide them with proper care and maintenance throughout the growing season to ensure their health and longevity.
While tender perennials may not come back every year in the same way hardy perennials do, with proper care and storage during their dormant period, they can continue to thrive and grow for many years. It’s important to understand the specific needs of each type of tender perennial and tailor your care accordingly.
