More and more people want to manage their own balcony garden sustainably. Because: organic gardening is good for the Urban Climate and biodiversity, protects our wallet and improves our ecological footprint. We have compiled the six most important tips for you about the organic balcony garden.
Buy high quality Earth for your balcony garden
Rather spend a little more money on your potting soil and buy peat-free soil in organic quality. Cheaper soil is often not structurally stable and sometimes even contaminated with unwanted foreign objects such as glass, stones or plastic residues as well as heavy metals. For climate protection reasons, peat should be avoided as far as possible. By the way, the peat-free nature must be declared on the packaging, which is not yet self-evident even with organic soils. For cultivation or herb cultivation, a special, nutrient-poor cultivation soil is recommended.
If you have used good potting soil in your balcony garden, you do not have to change it completely every year at the beginning of the season in the planters. It is often enough if you remove the top layer from the pots and refill fresh soil. The old potting soil can still be used for frugal summer flowers, provided it does not consist only of dense root network. Simply mix them 1: 1 with new substrate and spice them up with compost, worm humus, Bokashi (fermented organic waste), Horn shavings, Horn meal, Horn Gries or soil activators.
Produce your own fertilizer
A practical natural cycle begins with setting up a worm box directly in the kitchen or on the balcony. Leftovers that remain when cleaning vegetables can be disposed of directly in them. Thousands of earthworms in conjunction with millions of microorganisms turn these organic wastes into valuable worm humus, with which they can fertilize all year round. In addition, worm boxes are very easy to care for and can also be found in small rooms. And best of all: worm boxes don’t stink! Instead, they exude a very pleasant forest smell.
Use planters made of natural materials
Plastic is undoubtedly a practical material – for reasons of Nature Conservation and waste prevention, you should do without it, because still only a relatively small proportion of the plastic waste is recycled. For our grandparents, planters made of fired clay, galvanized steel or hardwood were still a matter of course. These alternatives still exist today, although they may be slightly more expensive, heavier and unwieldy than plastic containers. If you still want to use plastic pots, you should prefer products made of recycled material.
