Homemade Weed Control: no need to poison children


acidif there is a woody plant i want to be rid of, i cut the plant about 1 foot from the ground. this leaves a good amount to pull the whole root ball from the ground.  and then i pour a few drops of hydrochloric acid into the top where the cut is.

Hydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride in water. It is a highly corrosive, strong mineral acid with many industrial uses. Hydrochloric acid is found naturally in gastric acid. Wikipedia

Alternatives to chemical weed control
The cheapest weed control option is obviously prevention. There are many practices that we can adopt to ensure we do not introduce weeds onto our property.  There are 6 principles of weed management:1. Awareness – be aware of potential and existing weed problems.

2. Detection – look for any new weed infestations before they become too large or widespread.
3. Planning – Prioritise the treatment of weeds, what weeds threaten the profitability of your grazing    enterprise the most e.g. lippia, creeping lantana.
4. Prevention – far better than a cure, a $100/hour for a contractor to clean down seed laden machinery is much cheaper than any 20 litre drum of chemical.   Another example is feeding hay and grain only in designated areas to reduce risk of new ween introduction.
5. Intervene – Do it early this keeps a potentially large problem manageable.
6. Control and monitor – any weed needs to be monitored after control to ensure success.

Why is acid always added to water, and not the reverse?

A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it. So Always Add Acid to water, and never the reverse.

Weed and Grass Killer Organic

Vinegar 5% is only slightly effective on many plants and works only in very hot dry weather.

Pickling Vinegar 9% works much better kills small plants works best in hot dry weather.

Dissolve 12 lbs. of salt in 5 gallons of boiling water. Works great in hot dry weather. Water softener salt is $5 for 50 lbs. Lowe’s and Home Depot.

Pickling Vinegar plus 10% salt works better. Kills most small plants except for the large 2 ft tall weeds, thistle weed and other hard to kill large weeds.

Stomach Acid is Hydrochloric Acid = Muriatic Acid = Brick Acid. Muriatic Acid contains 60% water. Dissolve 3 lbs. of salt in 3 gallons of hot water then add a gallon of 40% strength Muriatic Acid. Kills all weeds and grass.

Muriatic Acid is $4 and up per gallon, swimming pool supply has it the cheapest.

Almost forgot to mention. Put dish soap in the water it makes it stick to the plants. Some plants water runs right off like it is oily.

I sprayed some weeds today about 10 am. It is now 6 pm the weeds are dead.

I mixed 1 quart of swimming pool type 30% muriatic acid with 2 quarts of water. Nothing else was added. Temperature here has been about 80 degrees all day. Now at 6 pm we are having 20 mph winds. Weeds are dried up and dead.

10% acid and 90% water works great.

Kills, pig weed, rage weed, lambs quarter weed, Ambrosia weed, several others.

Our HOA has 1 mile of fence line between pasture land and the road. In July 2015 I purchased 1200 pounds of Cargill TopFlow sodium chloride fine ground I used a Scotts professional spreader on the max setting of 15. After 1 week all grasses and most weeds are dying. Crabgrass, thorny weeds and vines look fine. Will repeat this in 3 weeks and again this winter (2015-2016). Hoping this is enough. Spring 2016 will tell. Looking for a 5 year solution. I may have to reapply 1x per year, but that is fine, compared to every 3 mos of Eraser (Round Up equiv) and I can do this in 1/10th of the time.
