ROCHESTER, Minn. – As colder temperatures approach, it is essential to bring in outdoor plants before they are damaged by frost.
Neil Imsdahl, manager at Sargent’s on 2nd, emphasized the urgency. “This week, we’re expecting some chilly overnight lows. Make sure to bring in or protect any tropical or tender houseplants that you want to save,” he said.
To shield plants for a bit longer, Imsdahl suggested covering them with a cotton cloth. For those planning to move their plants indoors, he advised transitioning them to a garage space first. “Treat them for bugs before bringing them inside, and they will be ready to go,” he explained.
Perennials require a different approach, especially those planted in the ground. Imsdahl noted that after two or three hard frosts, much of the vegetation will fall to the ground. Gardeners can either compost the fallen foliage or cut it back to about three or four inches above the ground. However, trees and shrubs should not be pruned until temperatures rise back to the 50s in spring.
Imsdahl also recommended giving trees and shrubs supplemental water during the day, as this fall has been particularly dry.
As fall progresses, Sargent’s sees an increase in customers asking about plant care. “It’s very common this time of year. Many people want to save the plants that have been outside,” Imsdahl noted.
