Some best bets include calendulas, pansies, Iceland poppies, primroses, and violas. Cyclamen are especially good in fast-draining containers in filtered dappled light. Unless you have especially well-drained soil, dig dahlia rhizomes, begonia tubers, caladiums, and gladiolus corms after their foliage has completely died down. Trim off remaining dahlia leaves and stalks, but don't cut the stems shorter than five inches from the swollen root. Handle them carefully, as bruising and puncture damage will encourage decay.
Cannas can stay in the soil through the winter, but cut the old flower stalks to the soil level.
For the last time, water cacti and succulents that will go dormant during the winter. Normal humidity will be sufficient moisture for the winter. Prune to shape evergreens like arborvitae, juniper, magnolia, pines, pittosporum, and spruce. This is a great way to get trimmings for holiday decorations while manicuring the plants. This will also allow wind to escape through the tree and not blow it down.
