Recycling potting soil from the previous year

Recycling potting soil from the previous year


Seam the summer, it means again to drag soil into the beds. But does that have to be? - Tips on how the soil nourishes the flowers not just for a single season.

With the first warm sunshine of the year, all hobby gardeners awake suddenly from hibernation. It's time to make the beds fit for the summer. As flower shops and garden centers fill up with colorful plants again, work can start.

Often the one or the other asks the questions: can the earth from the previous year be recycled? Are the nutrients used up or have pathogens taken care of? However, these questions can not be answered on a flat-rate basis. It all depends on what kind of plant it is and how well the soil was taken care of last summer.

Potted plants for the balcony

Especially for city dwellers, flower boxes mean a little piece of nature in their own home. The bright yellow or blue of a balcony plant brings some color into the gray concrete desert and some summer flair in your own four walls. But they have to heave the fresh soil from the home improvement store home and, if possible, into the fourth floor of an apartment building.

But to make sure that the flowers look the way they want, this is unfortunately necessary. For balcony plants, the annual replacement is recommended. Due to the cramped culture systems in the pots, the soil is deprived of nutrients and many pours increase the salt content. In addition, there are often harmful germs in the soil that attack the newly planted flowers.

For these reasons, it is enormously important for potted plants that the soil contains a substrate with sufficient water and air capacity. If she has been looking after the wellbeing of her offspring for one season, she can generally no longer have these characteristics.

Bedding and Vegetable Plants in the Garden

Even in beds, plants grow close to each other and the soil therefore has to overgrow have enough nutrients. Especially in the rearing small plantlets are dependent on much nutritious, so they quickly come to power. It is not advisable to give the soil a rich crop for two consecutive years, without fertilizer or other resources.

However, changing the entire load is usually not necessary. If old plant remains are largely removed and the soil is enriched with some fertilizer or mixed with nutrient-rich compost, fruits and vegetables thrive without any problems.

Small tip: If the soil is used for several years in a row, make absolutely sure that no vegetables of the same botanical family are used plant one after the other at the same place. Otherwise, germs easily germinate and the following culture threatens to wither away early.

Preparing the Earth

Two things have to be taken care of in order to reuse as much soil as possible. It needs to be well ventilated and supplied with sufficient nutrients at all times.

The potting soil from the retail trade often changes the structure after a season, becomes impermeable to air and collapses. As a result, the roots do not get enough oxygen in the following year. A green manure or mature compost loosens the soil and prevents this process very reliably.

In a green manure, for example, clover or lupins are sown before winter, as they nourish the soil. In contrast, plants such as rye or vetch are set, as their long roots ensure that the soil remains loose.

Even with the help of various slow-release fertilizers, bedding and potting soil can be processed. Horn meal, compost and sheep's wool or horse manure pellets are particularly well suited to successfully replanting.

Dispose of old potting soil

If potting soil has been used for some years now, thanks to good care, the time has finally come to dispose of it. Even in the city, there are better ways than the household refuse to separate from the old earth.

If there is a bio bin in the house, it is a suitable place. If you do not have the option, ask the local waste department for locations of so-called green containers. A few cemeteries also make tons available to the public in order to remove remnants of gardening.
