Plants need a lot of nutrients to grow healthy. Therefore, many hobby gardeners think much fertilizer helps a lot - especially in the vegetable patch! However, this theory is not correct in such a general way, because they exist, the plants that need only a little to bring good yields. If the so-called weak-eaters are over-fertilized, the dream of harvesting happiness melts away.
What are weak-eaters?
In terms of their nutritional needs, garden plants are divided into three groups: heavy-duty, medium-heavy and low-consumption. Particular attention is paid here to the nitrogen consumption of the respective plant. While starvationers consume a lot of nitrogen in the course of their growth and ripening, lesser eaters only need very small amounts of the vital plant nutrient. This plant division is particularly important in fruit and vegetable cultivation.
The group of the weaker ones include fruit plants that naturally grow on barren soil, such as most herbs (except basil and lovage), beans, peas, radishes, corn salad, rocket, fennel, olive trees, Jerusalem artichoke and purslane. Also lettuce and bulbous plants such as chives, garlic and onions are often counted among the low-consuming plants. It should be noted that the classification into high, medium and low-level users is not uniform and the transitions are fluent. More valuable than the theoretical classification here is your own horticultural experience.
Beans do not leach out the soil, but even improve it for the postcultures
How are weak-minded people cared for?
The term "weaker" does not mean that this group of plants does not absorb nutrients. But unlike most garden plants, those who are weaker do not need additional fertilizer, because they can either cover their nitrogen needs themselves, or they are simply very low overall. An additional supply of nitrogen leads to an overload in low-consuming plants, which weakens the whole plant. This makes it susceptible to pests.
Spinach and lettuce store unhealthily high levels of nitrate when overfertilized. Even fresh, pre-fertilized potting soil is therefore already too much of a good thing for some weaklings. Therefore, this group of plants is well suited for planting on heavily used surfaces in a partially spent soil or on naturally poor soil. Loosen the bed well before planting, so that the roots of the new plants can easily gain a foothold, and do not mix more than two liters of mature compost per square meter, because many weak-minded people like fine-crumbled, humus-rich soil. After planting it is lightly watered and no longer fertilized.
Salads and herbs are in the garden (with a few exceptions) to the weak-eaters
Weaknesses in the crop rotation
Weak starters are excellent as the last seed in the cycle of crop rotation. Low-savoring herbs such as thyme, coriander, curry herb, spice sage or cress, which are sown every year anyway, ensure a phase of soil regeneration due to their low nitrogen consumption. After strong and middle earners have demanded abundant nutrients from the soil during the previous growing seasons, weak-eaters provide for a rest - without the hard-working gardener having to do without a harvest. In addition, legumes (legumes) such as peas and beans even provide soil improvement through special nitrogen-forming bacterial symbioses.
