1. Wild craft or buy some dried nettles from your local health food store, as mentioned in the advanced directions.
2. Steep one ounce of dried nettles in one cup of boiling water for anywhere from 20 minutes to one hour.
3. Strain the leaves/stems out of the tea.
4. Dilute your brew 1:10 and use immediately.
Tip: After you strain the tea, put the leftover pulp into your compost to give it a nice boost.
Cautions: Not every fertilizer works for every plant. Some plants, such as tomatoes and roses have a difficult time with the high level of iron in nettles. This mixture is best for leafy plants and heavy feeders. When in doubt, start slowly with low concentrations and move from there as the plant responds.
The quick method is going to give you a subtler effect, but it will still feed your plants. And if you’re brewing some tea for your garden you might as well brew a bit for yourself (much more diluted of course) and enjoy a cup for good health.
If you want to get super crafty you can also try adding these herbs to your nettle mix or creating a separate fertilizer made from:
Comfrey (Symphytum officinale): High in magnesium, phosphorous, and potassium.
Horsetail (Equisetum arvense): High in silica, which is wonderful for strong bodies and plants.
Best of luck learning about and using these amazing weeds to your advantage!
