Sweet Spanish Chestnut, Large Trees

Sweet Chestnut Trees

Castanea sativa, is large, with a stout trunk and strong, fairly short main branches that create a shaggy canopy starting quite close to the ground. Sweet chestnuts, which can reach 30 metres in the right position, will grow on almost any well-drained soil apart from chalk. The nuts are edible - and delicious.

This rugged, deciduous tree has lush, glossy, lance-head shaped leaves with serrated edges that turn bronze-gold in autumn. It produces fairly insignificant pale yellow catkins in June/July which are pollinated by bees and ripen into eating chestnuts in early winter. It is an excellent parkland or woodland specimen. It is a very long-lived tree, and old specimens can be exceptionally beautiful, with thick, spreading branches and intricately ridge bark which seems to spiral around the trunk.

Did You Know? 

Spanish chestnuts were hugely important to the Roman Empire, which was responsible for increasing its range across the Old World and for introducing it to Britain some 2,000 years ago. Sweet chestnut porridge was the staple diet of Roman soldiers on campaign. In Sicily there is an ancient sweet chestnut that is thought to be over 2,000 years old, called the Castagnu de Centu Cavaddi, The Chestnut of One Hundred Horses, which refers to a legend about a Spanish queen and her company of 100 knights taking shelter under this massive tree in a storm. Chestnut wood is strong and almost rotproof, making it ideal for outdoor uses such as fencing.

Castanea vesca and Castanea vulgaris are former names.

Notes on planting Sweet Chestnut trees:
Sweet Chestnut trees are vigorous and will grow well in any well-drained soil except chalk. They are hardy, but they don't bear good crops in Scotland unless the summer is hot and sunny. Established trees are very drought tolerant. They can grow on the coast. They will not grow well if the site is very shady, wet or on chalk.

Prepare your site before planting:
It is good to dig over the site where you plant a tree several months in advance. Kill the weeds first: for tough weeds like nettles, brambles and ground elder, you will usually need weed-killer to get rid of them. When you dig the soil over, remove stones and other rubbish and mix in well-rotted compost or manure down to the depth of about 2 spades.

Watch our video on how to plant a tree for full instructions.
Remember to water establishing trees during dry weather for at least a year after planting.

Tree Planting accessories:
Prepare your site for planting by killing the weeds and grass.
You can buy a tree planting pack with a wooden stake & rubber tie to support the tree and a mulch mat with pegs to protect the soil around the base of your tree from weeds and drying out.
We suggest that you use mycorrhizal "friendly fungi" on the roots of all newly planted large trees: if your soil quality is poor, we strongly recommend it.
You can also improve your soil with bonemeal organic fertiliser.
