balcony plants

A balcony is created with plants and flowers even in the smallest space usually very diverse. Flowering flowers often alternate with green plants, herbs, cacti or even small Mediterranean trees, such as a lemon or olive tree. But all these flowers and plants on the balcony are also very different in style and care. For example, flowering plants need more fertilizer than those that have "only" green leaves. Even plants that are to bear fruit must be fertilized differently again. But one thing all these flowers and balcony plants have in common, they are cultivated in a pot or bucket and not in the field as in a garden. Therefore, it is important to ensure that these are not overfertilized in such plants cultivated in the tub. Because in addition to too little fertilizer can also damage too high a dosage. And especially with potted plants, the overdose can not drain off immediately, as is the case with outdoor plants, where the fertilizer can drain faster with the irrigation water into the soil.
