umbrohutõrje _äädikas

seda, et umbrohutõrjeks äädikat kasutada, ma teadsin. iseasi muidugi, kuidas see pikas perspektiivis ntx paekivile mõjub, kui peenravahed on paekiviga sillutatud. aga et soola võiks ka lisada, tundub huvitav.... kuigi see ilmselt pole pinnasele väga hea?

Option #1) Homemade Weed Killer: 1 gallon of vinegar, 1/2 cup salt, liquid dish soap (any brand). Put salt in an empty spray bottle and fill it the rest of the way with white vinegar. Add a squirt of liquid dish soap. This solution works best if you use it on a hot day. Spray it on the weeds in the morning, and as it heats up it will do its work. 
Option #2) Learn about wild edibles and you may be able to harvest a lot of the "weeds" in your yard for culinary and/or medicinal purposes.
