Sowing green manure in the fall: several mixtures for the raised bed in the vegetable garden and greenhouse.

Supply the raised bed in the kitchen garden or greenhouse with valuable nutrients. Fall is the right time to sow a mixture for green manure.

Sowing green manure: a simple method of improving the soil.

Green manure in autumn the most important for raised bed

Every amateur gardener looks forward to a bountiful harvest. However, crops need a lot of nutrients during the growing season for fruiting. They extract this from the garden soil. At the end of summer, the soil in the kitchen garden is therefore very lean. Especially the soil in the raised bed must therefore be fertilized if delicious vegetables are to grow there next year.

Green manuring is an environmentally friendly method that can improve the garden soil. It involves sowing certain plants in September. In doing so, one chooses certain species that grow quickly and can be “harvested” after a short time. The cuttings are then mixed with the soil in the raised bed and decomposed by the microorganisms in the soil. The resulting humus mass again provides nutrients and improves soil quality.

The plants that come into question for green manuring perform another very important function. They can root even loamy soil and thus loosen it.

In addition, sowing the plants for green manure is very simple. You don’t need to worry about the seeds, and the maintenance is also straightforward.

Perhaps the biggest advantage of this method is that the nutrients are not released into the soil all at once. The clippings gradually decompose and release them. Therefore, green manure acts as a kind of slow-release fertilizer. It is perfect for the kitchen garden, where many vegetables are heavy eaters.

Green manure is suitable for mixed crops

This fertilization is especially recommended for mixed crops. There, the different plants also have different demands on the soil. If you add compost to the soil, it will be quickly washed away by rain and snow. Only plants that have deep roots can absorb the nutrients. In contrast, the green manure method can provide nutrients for both shallow-rooted plants like radishes and deep-rooted plants like cauliflower, asparagus, tomatoes and red beets.

Green manuring also allows you to avoid the top layer of soil being washed away by rain.

Bottom line: green manuring is a simple way to improve your soil. You can save money and time by choosing the right mix and do something good for the environment in the process.

Green manuring in the fall: plants for the raised bed.

Make your own green manure mixture for raised bed

When choosing the right mix for the vegetable garden, your main consideration should be the plant family. Avoid incorporating crops and green manure plants from the same family one after the other. The following plants are great for green manures for raised beds :

  • Alfalfa
  • Buckwheat
  • Meadow clover
  • Fenugreek
  • Rye
  • Field bean
  • Ryegrass
  • Brown mustard
  • Bee pasture
  • White clover

Mixtures for the raised bed in the vegetable garden

Alfalfa and sandy oats: mix the seeds in a 1 to 1 ratio. This combination provides nitrogen quickly and suppresses plant growth. This mixture has another advantage: the plants die in winter and form a mulch layer on the soil, protecting it. This prevents the nutrients from being washed away by rain and snow.

Green manuring in winter plants for greenhouse

Winter roe and winter vetch: in a 4 to 1 ratio, this combination is perfect for late fall green manuring. Winter roe easily tolerates the cold and loosens the loamy soil.

Mixtures for the raised bed in the greenhouse.

Bee pastures and true buckwheat: in a ratio of 1 to 1. True buckwheat is very fast growing and its flowers are an important food source for bees and other pollinating insects in late autumn. Cut the plants when they have already flowered for 10 days.

Clover and forage pea: in a 2 to 1 ratio. Clover suppresses weed growth, attracts beneficial insects such as ground beetles, and helps control the lesser cabbage whitefly. In addition, the plant forms beautiful flowers and can tolerate shade well. Perfect for the raised bed in the greenhouse or in a shady spot in the kitchen garden.

Of course, you can use the mixtures for the greenhouse in the garden, and vice versa. Above all, it is important that you mix the seeds in the right proportions.

Sowing green manure in the fall: instructions.

Prepare green manure in autumn useful tips

You can sow the plants once a year, preferably in September. Proceed as follows:

First, remove weeds and loosen the soil with a shovel. Then sow the seeds as wide as possible, over the entire surface of the raised bed. Then cover the seeds with soil. If the day is sunny and the soil has dried a bit, you can water it. Green manure plants can handle little care. Water them only when necessary. Depending on your preference, you can cut them down after several weeks and incorporate the clippings into the soil. Another option would be to just leave the plants.

Most of them will die after the permafrost settles in. The dead plant parts form a mulch layer and protect the soil from rain and snow. They are gradually decomposed by soil life and are no longer visible in the spring. Then you can also plant various vegetables .
