I'm a beginner gardener and this is my first winter with some perennials, including rudbeckia, common mallow, and lupins (which I might remove because I'm not a fan). Can anyone give me advice on what to do with my perennials during the winter? I've heard they require different care types, so how can I tell if a plant has actually died or if it's just dormant for the season? I also have a flamingo tree—any tips on how to protect that in winter?

I usually just leave my perennials as is until February when I start trimming back and adding some mulch. Keeping them untouched helps provide shelter for insects during winter. Plus, there's something beautiful about seeing those delicate frost-covered plants! Whatever you do, try to keep the tops on for winter protection, especially from harsh weather.
For winter care of perennials, the approach can vary quite a bit. Some plants die back completely while others stay above ground, so it’s important to check individual care guides for your specific plants. A layer of mulch is often helpful to insulate the roots against the cold. Websites like RHS or Gardener’s World are great resources for tailored advice!
Most perennials will bounce back in spring if they looked healthy before going dormant. Just be aware that if a plant is over four years old, you might want to divide it to keep it thriving. Check the RHS site to confirm if your plants are indeed perennials, and hold off on drastic measures until you see new growth next spring!
