If your peonies need dividing or transplanting and you didn’t get to it last month, do it now. Plant “eyes” no more than two inches deep, or the plants might not flower. Enjoy late blooming annuals and perennials in the fall garden. Montauk daisies and many new hybrid sedum varieties such as ‘Neon’ make good choices.
Flowers: Sow seeds of next year’s biennial flowers, such as Canterbury bells, forget-me-not, foxglove, hollyhock, pansy, sweet William and verbascum. Pansies that are started now get a jumpstart for earlier bloom next spring.
PERENNIALS: Time to plant new perennials
Fruits and vegetables: Pot up plants of chives, parsley and rosemary. Grow them in a cool, sunny window or set them in a cold frame to over-winter. Before you move your plants indoors, clean foliage with water and check plants for insects. Continue regular harvests of summer crops.
Trees and shrubs: Trees and shrubs are beginning to shut down for winter. Pruning or fertilization at this time may disrupt this process so that the plants become vulnerable to winter injury. New growth that appears at this time could die when freezing temperatures arrive.
Lawns: If you need to reseed or spot seed, finish by the end of the month to give roots time to grow before winter. Grass seed grows best in well-prepared soil with good soil contact and must be kept evenly moist to become established.
Houseplants: Consider creating a window garden (also sometimes called a greenhouse window) for the houseplants you’ll bring in later this month. It’s a window dressed up with glass shelves. These make for easy maintenance of houseplants and have an appealing look.
