Planting a raised bed in autumn: that’s behind it

Not only the shorter days cause problems for our plants in autumn: Frost and moisture, in particular, mean that many plants come to an early end. But here the raised bed has a decisive advantage: On the one hand, the water flows away much faster through the drainage layer in the raised bed, so that vegetables and Co. do not get wet feet. On the other hand, the various layers of soil continue to rot in autumn and release energy in the form of heat – the raised bed has a built-in heating system for cold days. This ensures that the plants are affected by frost and cold much later than their counterparts outdoors and can grow much longer.
Planting a raised bed in autumn: tips and tricks to extend the season
But even in the raised bed, it gets too cold for the plants at some point – fortunately, there are a few tips and tricks on how to extend the season a bit: An excellent way to keep the raised bed comfortable even during the first night frosts in autumn. this must be covered with a foil tunnel. The heat collects so effectively under the film that vegetables can be grown well into winter.
Regular ventilation on sunny days is mandatory, otherwise the risk of fungal infections increases. A cold frame or greenhouse attachment also works according to this principle and is ideal for autumn cultivation (many manufacturers already have suitable, quick, and easy-to-assemble solutions for their raised beds in their range). But also the mulching of individual vegetables or the laying of fleece can cause a temperature increase of up to 5 ° C: This small temperature difference alone has an enormous effect on the plant growth and ensures a better harvest.
Plant raised beds in autumn: Suitable vegetables
If you still want to harvest something in autumn, you usually fall back on the classic autumn vegetables. Sown in summer, these types of vegetables ripen into autumn and also feel right at home in the raised bed. Cabbage types such as Chinese cabbage, broccoli, or Brussels sprouts are perfect for the raised bed, but carrots or fennel also benefit from their new home.
In autumn, of course, you can also grow the typical winter vegetables that normally have a permanent place in the bed. The best way to do this is to grow the seedlings indoors and plant them later as young plants. This can still be done in September or October without any problems, but you must expect that the harvest will not take place until spring. Kale, spinach and the like ensure full raised beds in winter, after all, they can withstand the cold and frost.
Tip: So that the vegetables feel comfortable in your raised bed, you should use high-quality and drip-free organic soil. In this way, you ensure that your plants find the best conditions and a rich harvest is coming up soon.
But it’s not just autumn and winter vegetables that are easy and uncomplicated to harvest this late in the year: almost all salads, as well as leeks and radishes, are perfect for the bed because they have a very short growing season. So they can be harvested before the days get too short and the first heavy frosts appear. With all vegetables, however, the rule is that they should never be harvested at temperatures below zero – this can not only harm the plants but also cause the leaves to become mushy when thawed.

Plant raised beds in autumn: green manure instead of vegetables
Would you rather do something good for your raised bed and don’t necessarily need fresh vegetables in winter? Then green manure is just the thing: Instead of leaving the bed empty in winter or growing vegetables in it, you can also plant your raised bed with hardy legumes ( Fabacea ) as green manure. The main advantage of these plants is that they fix nitrogen in the soil with the help of nodule bacteria and thus offer the soil natural regeneration in winter. At the same time, they also protect the soil from the weather and erosion to which a “bare” bed would otherwise be exposed.
Clover ( Trifolium ) and Esparsette ( Onobrychis ) in particular have proven to be good green manures and are not only useful but also look good. In early spring, the legumes that have been grown are then dug under – here they also serve as valuable fertilizer. With this winter pampering program, your bed will be perfectly prepared for the new gardening season in spring.
