Fall is a great time of year to work outside. A lot of garden and landscape chores are neglected over the Summer and it's not too hot, cold or wet to do them in Autumn.
Fixing up the landscape will make it look nice through next Spring. Some tips are:
After the first frost, dig up Summer flowering bulbs like cannas, dahlias and gladiolus.
Many perennials can be divided and replanted as they go dormant.
One thing that many people want to do in the Fall - but probably shouldn't - is pruning.
Plant small plants like ground covers before the first frost so they can establish a root system before Winter.
Harvest any green fruit that will be frosted and bring them inside so it can ripen indoors.
Fall is the best time to rototill the garden because the soil usually isn't too wet.
