Yesterday afternoon I picked up 2 kg of Field Horsetail, Equisetum arvense. I used half a kilo to make a tea and put the most of it on the table to dry.
This tea is very god when used as a plant spray. It is a natural fungicide and strengthens the plant's health.
Here is the recipe:
1 kg of fresh plant (or 150 g dried)
10 L water
Leave it 24 hours. Tomorrow, put some water and the whole of the horsetail into a pot and cook for half an hour. Leave it to cool down. Add the rest of the water and strain. To make a spray, use 1 part tea and 5 parts water.
