To save potted mums, it is important to take some steps before the first frost hits. Firstly, assess whether your mums are in pots or containers that can be easily moved. If they are, it is recommended to plan to overwinter them in your garage. This will provide them with protection from the harsh winter conditions.
Once you notice the first frost approaching, it is time to prepare your mums for overwintering. Start by cutting back the plants as indicated above. This involves trimming off any dead or damaged foliage and stems. By doing so, you are promoting healthier growth when the next growing season arrives.
Next, it is crucial to provide insulation for the mums during their time in the garage. Begin by covering the plants with approximately 3 inches of mulch. This layer of organic material will help to insulate the roots and protect them from extreme temperature fluctuations. Mulch also acts as a barrier against moisture loss, which is particularly important during the winter months.
After applying the mulch, cover the entire pot or container with an old sheet or burlap. This additional layer will further shield the mums from cold drafts and temperature extremes. It is essential to secure the cover tightly to prevent it from being blown away by strong winds.
Move the potted mums into a cool garage. The garage should ideally maintain a temperature range of around 35-45 degrees Fahrenheit (1-7 degrees Celsius). This temperature range is sufficient to keep the mums dormant during the winter months without exposing them to freezing temperatures. It is important to avoid heated garages or areas that may experience extreme temperature fluctuations, as this can disrupt the dormancy period.
Throughout the winter, periodically check on the mums to ensure they are not drying out. If the soil feels dry to the touch, provide a small amount of water to keep the roots slightly moist. However, be cautious not to overwater, as this can lead to root rot.
When spring arrives and the danger of frost has passed, you can gradually reintroduce the mums to outdoor conditions. Start by removing the mulch and gradually acclimating the plants to outdoor temperatures and sunlight. This process can be done by gradually increasing the time spent outdoors over a period of a week or two. Once the mums have fully acclimated, they can be replanted in their permanent outdoor location or placed back on display in their pots.
Saving potted mums requires some proactive steps, but with proper care and attention, you can ensure their survival through the winter months. By following these guidelines, you can enjoy the beauty of your mums year after year.
