Fall landscape planting projects are ideal. The reasons are both ecological and economic. Cooler fall temperatures leave plants less stressed as they adapt to their new environment. But more importantly, fall soil temperatures are ideal for root growth. Plants can get six to eight weeks of root growth before winter. This gives them a big advantage when next summer’s heat arrives. The exception is that some trees, such as many Oak varieties, are ‘fall dig hazards’ and are best not planted in autumn. (Ask your nurseryman for more information). Don’t forget to water your new plantings, as fall can sometimes be very dry.
Deals can often be had on plants in autumn for fall landscape plating. Nurseries may drop prices if they are anxious to get rid of planting stock to avoid winterizing it or if they need to make room for holiday decor. Nursery plants will be larger at the end of the season, so you may get more plant for less money. Perennials can often be bought for half price or less since they are starting to die back. But put them in the ground anyway, and next spring they will shoot out strong. Landscape contractors may even lower installation prices if they want to get a little extra revenue before the seasonal shut downs.
Fall is perfect for pruning. It is much easier to see the branches and structures once the leaves have fallen from shrubs and trees. You will be able to determine which branches have die back and where certain diseases may need to be cut out. Thinning out trees and shrubs properly can also reduce potential winter damage from heavy wet snows or freezing rain. Pruning back perennials is a personal choice. Some professionals are adamant that perennials should be cut back in the spring so that the die back provides a winter blanket of protection. But if that is a messy look that drives you wild, go ahead and cut your perennials back in the fall.
Cooler weather does not mean the end to gardening. Autumn is a great time for fall landscape planting and pruning.
