Storing Carrots and Beetroot: The Sand Crate Method for Winter
A crate of sand and a cool room keep root vegetables crisp for months. Here is how to do it, step by step.
When the beds empty out, there is often still plenty of root veg in them. In the fridge it goes soft quickly, in a sand crate it keeps much longer. The method is old, simple and needs hardly any material.
Harvest first, then store: getting the timing right
Carrots and parsnips are frost-hardy and can stay in the bed as long as the soil is workable. Beetroot and celeriac only tolerate light frost. Lift them before the first nights with real sub-zero temperatures, on a dry day. Loosen the soil with a digging fork instead of pulling on the leaves, so the roots stay intact.
Prepare: twist off the tops, skip the washing
Twist the leaves off about 1 to 2 cm (half an inch) above the crown. If you cut too deep, the roots sprout in storage and lose substance. Let the soil dry and just brush off the worst of it. Washed roots rot faster. Set aside anything with cracks, pest damage or bruises: that goes straight to the kitchen.
The sand crate: how to layer it
Take a sturdy crate with drainage holes and start with a layer of slightly moist sand. It should just hold its shape when squeezed, without dripping. Place the roots so they do not touch, then cover them with sand. Repeat for the next layer. This way, rot cannot spread from root to root.
The right spot: cool, humid, dark
Aim for 0 to 5 °C (32 to 41 °F) and high humidity. An unheated cellar, a garage or a frost-free shed can work. Do not put the crate next to apples: ripening fruit gives off ethylene gas, which turns carrots bitter. If your shed can freeze, cover the crate with burlap or straw as well.
Check in and use what you have
Take a look in the crate every two to three weeks. Remove rotten roots right away, and give dry sand a little water. With some luck, carrots and parsnips keep like this until spring, and beetroot and celeriac usually last about as long. Use first whatever shows bruises or starts to shrivel.
Write down what lasted
Note which variety lasted how long and what temperature the crate was kept at. Next year you will know exactly which varieties are worth storing. In Rootivo you can record such observations right in your garden journal and find them again when you plan in spring.
