The show's creator Marc Cherry announced earlier this month that the show will finish after the upcoming eighth season.
Joosten, who stars in the show as Mrs McCluskey, has now suggested that it is the right time for the series to end.
"I'm glad to be done with it," she told E! Online. "It's said everything there is to say and done it."
Joosten, who explained that she will "definitely miss" the crew, added: "There hasn't been that much for me to do anyhow because they don't know how to write for people my age... There haven't been any stories for me the last two years."
Desperate Housewives star Marcia Cross has described the end of the show as "bittersweet", while Felicity Huffman has confessed that she "cried at the kitchen table" when she heard the news.
The final season of Desperate Housewives will premiere on September 25 on ABC.
