The crucial question here is what proportion the individual elements should have. And this question can only be answered if you know the water and nutrient requirements of each herb. As a rule of thumb it can be said that herbs with a relatively high demand also require a high proportion of compost and garden soil, while one can reduce the proportion of sand or even completely omit it. In particular, Mediterranean herbs require relatively little water and only a few nutrients. Here it is important to increase the amount of sand and to do everything so that the earth can hardly store water.
What herbs wantThe following overview is intended to give you an approximate idea of the requirements of individual herbs regarding their water and nutrient requirements:
Rather low to moderate need
- lemon balm
- wild garlic
The soil for herbs with a rather high need for water and nutrients should always be humus rich and be able to store water easily. In contrast, herbs with a low requirement prefer a permeable, sandy and dry soil.
standard recipeAgainst this background, it should be relatively clear that a special mixture of herbal earth makes sense especially for herbs that require little nutrients and relatively little water. This is usually the case with all Mediterranean herbs. The following composition has proven itself:
- 50 to 55 percent garden soil
- 15 to 20 percent compost
- 30 percent quartz sand
Tip: Instead of quartz sand, other materials such as lava split, pumice sand or zeolite can be used. The compost in turn can be replaced by a mixture of peat and coconut fiber.
Prepare ready mixesAs mentioned, the self-mixing of an herbal soil is especially for Mediterranean herbs with low water and nutrient requirements in question. For all other types of herbs can be used without any problems ready mixes from the trade. Of course, these can also be used as the basis for your own mix - especially if you do not have access to garden soil and would like to grow the herbs in the flat. You simply replace the parts of garden soil and compost with the ready-made mixture and add plenty of quartz sand. A ratio A ratio of 60 to 40 (sand) is ideal. It is also important here to loosen up the soil extremely well, thus ensuring good aeration and good permeability. In addition, the drainage plays a crucial role.
Herb earth in the gardenIn order to prepare the soil in the garden directly to the herbal earth, one must first of all be clear about which earth exactly there one has. If the soil is already rich in sand, it is usually possible to save the addition of sand. On the other hand, if it contains a lot of loam, the gift of sand and an intensive relaxation are indispensable. You should also think about the laying of a drainage, because clay-containing soil naturally stores the water extremely well.
