In this article, we’ll show you how to grow a horse chestnut in water.
Did you know there’s a seed hiding inside the prickly fruit of a chestnut? Here’s a quick tutorial ton how to grow a horse chestnut in water.

Are all chestnuts edible?
As you go on a hunt for chestnuts and propagate them, you may want to roast the seeds and try them. Both toxic and edible chestnuts have brown nuts.
Horse-chestnuts, which contain a poison called esculin and can cause death if eaten raw, have a bumpy husk with a wart-covered appearance. They are rounded and smooth with no points.
Sweet chestnuts, however, are edible and covered with a spiny husk and pointed tips. When roasted, they are sweet, buttery, and soft.
Here’s some extra info to help you succeed:
Fake it till you make it
Like many seeds growing in cooler climates, chestnuts need a period of hibernation in the cold to germinate. To speed up this process, you can replicate nature by using the fridge. Wrap your chestnut seed in a moist (not wet) towel and put it in the fridge for 2-3 months between 0-2 °C.
Warm it up
Temperature is an important factor. Keep your baggie at around 25°C for the fastest results. Look for a spot in your house that’s consistently cozy & warm. Next to your furnace or hot water boiler is a good choice.
Keep mold at bay
Keep checking inside the baggie from time to time, to check if the paper towel is still moist. If not, add a little water to keep things steamy in there.
Check for mold as well. If you spot some, wash the nuts in a bleach solution. To achieve this, mix one part bleach with nine parts water. Rinse the seeds with boiled water which has cooled down and return them in the baggie.
Once the root is about 2-3 cm, take it out of the baggie, and let your seed grow further. You want the roots to always be in the water, but the seed to stay dry. The perfect tool for the job: a porcelain germination plate. It also helps to prevent the water from evaporating too fast.
