I saw this tip from Happy Farmers Tanim dito, tanim doon group posted by Ms. Joyce Tan. She said she used Stinging Nettle (Urtica Diodica) or Lipang-Aso in Tagalog as fertilizer.
According to Joyce Tan, this plant is rich in iron and good for lactating mothers. She said when she started her organic gardening, she make some research and found this Stinging Nettle which can be found in the wild. She said she’s taking the young plants and use it as organic fertilizer for her plants. Based on her post, it is rich in iron, potassium, zinc, calcium, magnesium, chlorophyll and copper.
The steps below were given by Ms. Joyce Tan as posted in Happy Farmers Tanim dito, tanim doon group:
Method 1: For 200g of Stinging Nettle, boil it with 1 cup of water. Strain, then mix with 10 Liters of water.
Method 2: Ferment the Stinging Nettle for 10 days or more. Fill a drum of stinging nettle then put a big stone on top it or any heavy objects. Fill drum with rain water or water from river, pond or lake. Do not use chlorinated water. Mix it every other days and if there is no more bubbles, it is ready to use. CAUTION: Use mask as it has bad smell. (Ratio: 1 Liter of mixture to 20 Liters of Water). Leaves used in the fermentation can be added on your compost bin.
According to Joyce, she’s applying this every 3-4 weeks.
Ms. Tan said that this fertilizer is ideal for leafy vegetable but for tomatoes, eggplants and peppers, she used them to boost her seedlings’ growth and stopped applying them when the plant start to bloom.
In Wikipedia, Stinging Nettles is used for gardening and it has a numbers of uses including the potential for encouraging potential insects. Nettles contains a lot of nitrogenous compound and used as compost activator or can be used to make a liquid fertilizer. According to Wikipedia, it low in phosphate but it has magnesium, sulphur and iron.
