Uporaba pokošene trave
V mnogih vrtovih se pokošena trava kopiči do te mere, da kompostiranje več ni primerna metoda odstranjevanja. Učinkovit način recikliranja presežne trave je uporabna za zastirko cvetličnih in zelenjavnih gredic. To zagotavlja, da vlaga dalj časa ostane v tleh in oskrbuje korenine rastlin s počasnim sproščanjem gnojil. Še več, ostanki trave obdržijo tla bolj rahla in zato je manj potrebe po uporabi motike. Ker trava razpada na gredicah, postane naravno gnojilo za vaše rastline. Ostanke trave je mogoče uporabiti neposredno iz zbirne košare kosilnice, vse dokler ne vsebuje semen plevela in trave. Da bi preprečili gnitje trave, sme zastirka biti debela do 5 cm. Še bolje je travo pred uporabo pustiti malo uveneti. Za boljše rezultate mulčenja uporabite GARDENA combisystem rahljalnik zemlje, s katerim na rahlo pomešate sveže ali suhe ostanke trave takoj po košnji. Če je potrebno, z dodajanje materiala vzdržujte debelino zastirke.
Čudežni ostanek: kavna usedlina
Used coffee grounds are a well-known miracle plant fertilizer. This is due to their high content of nitrogen, phosphorus, minerals and potassium, which make them a high-quality natural fertilizer. This type of fertilization doesn't even require a lot of effort. Simply collect old coffee grounds, spread on an old newspaper and let them dry out so that the coffee grounds can be spread more easily. Coffee grounds can be used to fertilize beds, potted plants, tub plants and house plants. How often you should use coffee grounds to fertilize a plant depends on the type of plant. House plants can only tolerate coffee once every six months. However, outdoor plants can be fertilized with coffee grounds up to four times a year. The best way to do this is to lightly sprinkle the coffee grounds on the soil surrounding the plant and then gently incorporate them into the earth. For potted plants and tub plants, the coffee grounds can be mixed in with the potting soil when planting. Any leftover coffee grounds can be thinly spread across the compost. Roses, geraniums, angel's trumpets, oleanders, hydrangeas, rhododendrons and azaleas all respond particularly well to coffee grounds as a fertilizer. Last but not least, this environmentally friendly fertilizer attracts earthworms, which loosen the ground and supply the soil and plants with nutrients from their excrement.
Ni posebno dišeče, vendar je zelo učinkovito
Not quite as fragrant—but still good for roses and all garden plants that require plenty of nutrients—is fertilizer made from horse manure. To prepare this fertilizer, put one shovel of manure into a bucket and fill with water. Then store the mixture somewhere where you can't smell it for three weeks to allow it to develop. You can then dilute the finished liquid manure with water at a ratio of 1:20 and use this to fertilize your roses. But be careful: The mixture develops a very strong, powerful smell! For those who prefer to take shortcuts: Simply dig in the horse manure directly between the roses.
Aside from liquid horse manure fertilizer, a concoction made from stinging nettles also develops a penetrating smell. Nevertheless, this kind of homemade fertilizer nourishes your plants in a natural manner thanks to its particularly high nitrogen content. To make a stinging nettle liquid fertilizer, cut a kilogram of fresh nettle leaves into small pieces and place in a bucket with approximately ten litres of water. To save water, rainwater is ideal for this fertilizer. You can also mix a small quantity of leaves directly into the soil with the plant or place them in the soil when potting plants. Cover the mixture and allow to steep for around two weeks. Your homemade natural fertilizer is ready once the liquid has darkened in colour and has stopped foaming. Dilute around half a litre of this homemade liquid fertiliser with water in a 10-litre watering can and water your plants with it once or twice a week. This natural fertilizer is beneficial for indoor plants, but also for all beds in the garden, except for beans, peas and onions. It is also beneficial to plants that are sensitive to lice if you lightly spray them with the liquid fertilizer, as this will create a crust of silicates that prevents the lice from piercing the plant cells and sucking them dry. This protection only lasts until the next time it rains and the layer is washed away.
Water used to cook potatoes is also a natural fertilizer for plants due to the vitamins released into the water during the cooking process. Simply cool the water after cooking and use it to water house plants and garden plants once a week. Mineral water that would be thrown away because it is no longer fresh enough can also be used as a fertiliser. Why not make the most of the water's high mineral content and let it benefit your plants?
