Trimming the plants back and removing spent flowers before overwintering will also contribute to their overall health and vitality.

To provide nourishment during their dormant stage, slow-release, high phosphorus fertilizer can be applied to mums’ roots. This will enhance their ability to withstand winter conditions and promote strong growth in the following season. In spring, it is essential to remove winter mulches and prune away dead foliage to rejuvenate the plants. Gradually acclimating mums to outdoor conditions after the last risk of frost has passed will help them adjust and thrive in their natural environment.

Protecting Potted Mums From Frost With Tarps Or Greenhouses

Potted mums, due to their containerized nature, are more vulnerable to cold weather and frost damage. Therefore, taking extra precautions to shield them from freezing temperatures is crucial for their survival. While following the general care tips for mums mentioned earlier, there are specific strategies to protect potted mums from frost.

  • Covering potted mums with tarps or blankets is an effective way to shield them from frost. By wrapping the containers with these protective layers, the plants are insulated and kept away from direct contact with freezing air. This method creates a microclimate that traps heat and prevents frost from damaging the plant’s delicate tissues.

  • In addition to using tarps or blankets, another option is to move potted mums into a collapsible greenhouse or any sheltered area that provides a controlled environment. This protective measure ensures that the plants stay shielded from extreme weather conditions while still receiving adequate sunlight for photosynthesis. By replicating their natural habitat, potted mums are given the best chance to survive cold temperatures and emerge unscathed when spring arrives.
