Landscaping plants and patio goods
In most climates, September gives gardeners about eight weeks to get new plants and shrubs into the ground and rooted before the weather gets cold, says Hillary Mendelsohn, author of "thepurplebook" series of shopping guides and founder of ThePurpleBook.com.
And garden centers are looking to get rid of their perishable merchandise -- "all that stuff they keep outside" -- while they can, she says. It might not be a good time to buy a leaf blower, but it's a great time to get a discount on landscape plantings, she says.
Pick up landscaping plants after Labor Day and get them in the ground, and you can save a lot of money, she says. Discounts are liable to be deeper in climates where cold weather is soon setting in, than in more temperate regions such as the West Coast, she says.
Patio items are on sale, too. Tables, chairs and barbecue items are on clearance -- from 50 percent to 70 percent off -- in a lot of instances, says Daniel Butler, vice president of merchandising and retail operations for the National Retail Federation.
The downside is that you might not find entire matching sets, he says. Instead, it's often going to be a piece here and there.
