Vegetable cooking water

Have you ever thought about it? The cooking water is rich in micronutrients released by the plants themselves! You can use their cooking water for the fertigation of the garden. Avoid using the cooking water of vegetables if they come from intensive agriculture and are therefore rich in pesticides and potentially harmful chemical compounds. In fact, you too should avoid eating such agricultural products. Generally, pesticides wash away from vegetables very easily, so you just need to soak the vegetables for 5 minutes, before cutting them and immersing them in the cooking water.

Macerated nettle

It is a very good onehomemade natural fertilizer. For the preparation, the whole plant (excluding the roots) is used in the measure of half a kilo of dry nettle or, more practically, a kilo of fresh nettle to be macerated in 10 liters of water.

The nettle macerate prepared in 12 hours, is used concentrated, distributed directly on the plants with a sprayer, if you macerate the nettles for 4-5 days, you will have to further dilute the fertilizer obtained. The nettle macerate provides nitrate, potassium, magnesium and other micro-elements.

Nettles are wild herbs, too often considered weeds. In fact, these "weeds" are very useful in the kitchen and, if you spot them in your garden, harvest them while they are tender. You can boil them and prepare an excellent omelette. The cooking water can become perfect natural fertilizer garden!

The best nettles are harvested with the first heat of summer. If, in your garden, you don't have nettles, you can buy the macerates from garden centers and agricultural consortia. Nettle macerate is such a "powerful" remedy that it could not be missing on Amazon where it is sold in concentrated 1-liter packs. Generally, 100 ml is diluted in 5 liters of water but always read the instructions because each manufacturer has concentrations and dosages of their own.

How much? The nettle macerate gets paid a bit like allnatural and organic remedies(so it's best if you make it yourself!). On Amazon, a one-liter bottle costs around 19 - 25 euros with shipping costs included in the price. For all the info:nettle macerate.
