Spring is known for gardening but did you know that fall is a great time to plant? Here are 7 reasons why you should consider fall planting: 1. Its cooler out, which is great for both plants and gardeners. Gardeners can take advantage of milder temperatures and enjoy fall planting without the sweat and oppressive heat of spring or summer. Ideally your fall planting should be done by early November, about 6 weeks before hard frost. And for the plants, cooler temperatures are ideal for root development because the ground and soil is still warm which will allow roots to grow until the ground freezes.
