How to Start It
★ Recommended for beginners
Buy two young trees, because a chestnut needs a second chestnut tree nearby to make nuts. Plant them in early spring while they are still bare and asleep, about 12 m apart, in a sunny spot with soil that drains well and is not limey. Pick a hardy, blight-resistant type sold for your area.
A chestnut is a big, long-lived tree, so it suits a large growing space rather than a balcony, and it starts bearing in about 4 years. Do not mix it up with horse chestnut, a different tree whose shiny nuts are poisonous: true chestnuts grow inside very spiny husks.
When To Start
Chestnut needs warmth. Wait until your last frost has passed and the soil has warmed before sowing.

Growing Tips
- 1Plant chestnuts in full sun, where they have room to grow into large trees.
- 2They need soil that drains well and is slightly acidic, and they struggle in heavy, wet or limey ground.
- 3Water young trees deeply once a week in their first 2 to 3 summers, then they can mostly fend for themselves.
- 4Spread compost and a ring of mulch around the base each spring, keeping it a hand's width from the trunk.
- 5Pick up fallen nuts every day or two, so weevil grubs inside cannot get into the soil and come back next year.
- 6In areas where chestnut blight is found, choose a blight-resistant type.

When to Pick
Gather in autumn when the spiny burrs split and the nuts fall
How to Harvest
- 1Chestnuts are ready in fall, when the spiny husks turn brown, split open and drop to the ground.
- 2Wear thick gloves, or roll the husks under your boot, to free the shiny brown nuts inside.
- 3Gather them every day or two, before squirrels do.
- 4Keep fresh chestnuts in a bag in the fridge and use them within a few weeks, because they are moist and spoil quickly.
- 5Cut an X in the shell before roasting or boiling, so they do not burst.
