Topping Up Your Raised Bed in November: Why It Sinks Every Year
Has your raised bed dropped noticeably since spring? Don't worry, that's normal – and November is a good time to top it up.
A freshly filled raised bed looks plump and tall. A year later, a hand’s width is often missing at the top. That’s not a mistake, it’s soil life at work. With a few simple steps in late autumn, you’ll start spring with a full bed again.
Why your raised bed sinks
In a raised bed, coarse material such as branches, leaves and plant remains rots in the lower layers. As it breaks down, it loses volume and the bed settles. This is most noticeable in the first and second year and slows down later. That’s intended: the decomposition provides nutrients and warmth for your plants.
The right timing
After harvest and before the ground freezes for good, the bed is usually empty and the soil is still easy to work. Clear away any diseased plant remains and leave healthy roots in the soil. If you already have winter vegetables like corn salad or leeks growing, just top up the free spots.
What to fill it with
Mature compost mixed with a little good garden soil works best. Spread it about five to ten centimeters thick and rake the surface smooth. Better skip fresh, unfinished compost, as it can over-fertilize young plants in spring. Coarse material belongs in the bottom layer, not on top.
Afterwards: cover instead of digging
A bare bed loses nutrients and structure to rain and frost over winter. Cover the surface with leaves, straw or mulch, three to five centimeters is enough. Leave corn salad and leeks uncovered, otherwise they can smother under the layer. You don’t need to dig: soil life works the compost in by itself over the winter.
A project for the whole family
Kids love to help here: sifting compost, pushing the wheelbarrow and spreading leaves. Use a tape measure to check how much space is missing to the rim, then measure again in spring. It’s a simple mini-experiment that shows how much happens in the bed over winter.
Plan next year now
Use the quiet season to think about what goes where next year. In Rootivo, the companion-planting lines layer in the bed editor shows which neighbors go well together, so you can plan your raised bed from the couch.
