Note that some dislike the scent of the flowers, particularly those of the European variety, and the spiny burrs that contain the nuts tend to create quite a mess when they fall in autumn – so choose your planting location wisely. It’s an easy mistake to make if you’re out foraging – and an unwelcome surprise to find out 10 years down the line if you’ve planted nuts that you misidentified!

Now that I’ve convinced you that chestnuts are wonderful, the only question is, how can you go about growing and caring for these trees yourself? Read on to find out! The chestnut really is a gift that keeps on giving. Thanks to their beautiful, rot-resistant wood that is used for everything from fence posts to house timbers, chestnuts are abundantly useful to woodworkers when they have reached the end of their lives as attractive ornamentals and sources of food in the landscape.
