How to Start It
★ Recommended for beginners
A named grafted tree fruits sooner and true to type. Plant two for pollination, in acid, free-draining soil, while dormant.
A grand, long-lived tree bearing nuts inside spiny burrs. Unlike most nuts, chestnuts are STARCHY and low-fat, eaten roasted or boiled, not raw. KEY: they're self-sterile, so you need TWO trees for any crop. They demand acid to neutral, free-draining soil (they hate lime and waterlogging) and plenty of room.
When To Start
Chestnut needs warmth. Wait until your last frost has passed and the soil has warmed before sowing.

Growing Tips
- 1Chestnuts need acid, free-draining soil and space above all.
- 2Get those right and they're easy and productive.
- 3Plant two for pollination.
- 4The nuts are starchy, so cook them (roast, boil, purée) rather than eating raw.
- 5Watch for chestnut blight in some regions, and gather the crop promptly before wildlife clears it.

How to Harvest
- 1Collect chestnuts as the spiny green burrs split open and drop.
- 2Use thick gloves or roll them underfoot to free the nuts.
- 3Use them fresh (they're high-moisture and don't keep like dry nuts); refrigerate or cook within a couple of weeks.
