Aubergines are demanding plants and need sufficient nutrients. There are several natural ways to do this.
Aubergines are one of the vegetables that not only need a lot of water, warmth and space, but also need some fertilizer on a regular basis. Especially in our latitudes, where the summers are often short and not nearly as warm as in Italy, Spain and Greece, aubergines do not grow as well without fertilizer as in warmer countries. Also, they don't bear very much fruit. So if you want to get a bountiful harvest, you have to do something about it and fertilize your eggplants regularly.
Of course you can use industrially manufactured fertilizers. But why use chemicals when organic fertilizers are just as good? You can also make the latter variant yourself.
How to fertilize your aubergines without chemicals
Fertilize eggplants when planting
Most plants should be fertilized a little when planting. This includes the aubergines. Instead of resorting to chemicals here, you can simply put some ripe compost in the planting hole. Then water well and you have created a good basis for strong aubergine plants.
Fertilize eggplants every 2 weeks
Stinging nettle manure is a very good organic fertilizer because it not only strengthens the plants' defenses, but also acts against pests and diseases. Once prepared, you can use the nettle manure again and again to fertilize your aubergines every 14 days. This ensures good and he althy growth of the aubergines and a good harvest.
How to make nettle manure:
❶ To make nettle manure you need a large container with a lid (e.g. a rain barrel). Now put as many nettles as you want in this container. Then add enough water to cover the nettles and put the lid on.
» A little hint: for the liquid manure you need 1 kilogram of fresh nettles for every 10 liters of water.
❷ After that you have to let the mixture stand for about three to four weeks andstir daily. During this time, the odor-intensive fermentation takes place, during which bubbles rise. If no more rise, then the fermentation process is complete.
❸ Once the nettle manure is ready, you can use it directly as an organic fertilizer. To do this, however, you must first strain the liquid manure. Then add 1 liter of nettle manure to 10 liters of water and water the aubergines with it every 10 to 14 days. The high nitrogen content of the nettles then ensures that your aubergines develop splendidly.
