Cut each stalk close to the ground with a sharp pair of scissors or a knife.
Gather three to five stalks in a bundle and tie each bundle with a piece of string.
Hang the nettle stalks in a place that receives plenty of air circulation. Space out the bundles so that they do not touch each other.
Allow the bundles to completely dry, which typically takes five to seven days. Dried stalks will be crispy, with no moisture.
Take down the bundles and strip off the leaves. Store the leaves in airtight containers, such as tins.
Boil 2/3 cup of water for each serving of tea you wish to brew.
Measure 3 to 4 tsp. of dried nettle leaves per serving, as recommended by the University of Maryland Medical Center. Place each serving in a mug.
Pour the boiling water into the mugs, dividing evenly.
Allow the tea to steep for three to five minutes.
Strain the tea by pouring it through a tea strainer or a cheesecloth.
