This is the best time to plant perennials, shrubs or trees, whether you are adding to an existing garden or planning a new one. These items should be planted at least six weeks before the ground freezes to allow them to settle in before the cold weather hits. Bulbs can wait a little longer, as long as they are planted before the ground freezes. If you have been thinking of adding to your garden or creating a new one, get moving!
Many garden centers have price reductions on most perennials, shrubs, and trees this time of year, some quite drastic. The plants may not look as lush as they do in the spring/summer, but they will survive and will look great next spring and summer. If your garden is on a strict budget, this is the best time to plant to ensure you get more bang for your buck!
Be sure to read the labels, choosing plants hardy in your climate zone. In the Kanata Ontario area, I stick to zone 4 or lower. My front garden gets full sun with a southern exposure and protection from winter/north winds so I can stretch to a zone 5 in that area of my yard. Also keep flower color, bloom time, shape, size, and foliage color in mind when making your choices. Read the labels, and when you get your purchases home, place them in your garden, still in the pots, arranging them so there is a variation in the above characteristics. For example, you don’t want three plants that bloom in may with pink flowers planted next to each other…
When you are satisfied with the placement, start planting. Some plants will be root bound after sitting in their pots all summer at the garden center, meaning their roots are tightly wound together, often taking on the shape of the container. You may even have to break the pot to get the plant out, but banging on the side of the pot with your trowel usually does the trick. If the roots are very dense/compacted, cut into them with a sharp knife or another tool a few spots around the outside bottom edge. This will allow the roots to spread out in the hole you are planting them in. Dig a hole slightly bigger than the root ball, mix a scoop of bone meal or blood meal for root nourishment into the soil at the bottom of the hole, fill the hole with water, then add your plant when the water soaks in. Water again and keep watered for the next few days. The cooler/wetter weather this time of year will keep them from drying out and getting scorched from the hot sun. If desired, you can add a layer of mulch to your garden, but be sure to leave a gap between the mulch and the crown/stem/trunk of your plant to discourage rot.
Bulbs come in many sizes and bloom times. In the stores they should be labelled with early, mid, late spring or summer bloom time. Again, choose a variety of color and bloom time. Plant in groups of five or more, not in a row! To keep squirrels from digging up your bulbs before you get to enjoy them, plant daffodils over top your tulips etc, in the same hole. Your hole size will depend on the size of bulb; the larger the bulb, the larger the hole you will need. Place bulbs pointy side up, tulips first, with a thin layer of soil on top, then the daffodils.
Fall is the best time to plant your gardens. The hardest part of planting your garden in the fall is waiting until spring to reap the rewards!
