Frequently Asked Questions
Why not steam?
There are many steam-based weeding tools, none of which work. Why? When you think of it intuitively, steam would seem to be an ideal means for weed control – so what’s the hangup?
There are two problems with using steam to kill weeds;
How does it work?
The HotZot works by shooting narrow jets of scalding 185F water at the crown of the weed. It is not necessary to spray all the leaves, just spray the crown of the plant will sever the connection between the root and the portion above ground. The water bursts the tissues of the plant down into the root. As the root begins to regenerate, the decomposing products of the dead root start to seep down the root channel and further compromise the root biome. The more damage you can do the the root biome the less likely the weed will have the energy to regenerate.
With a “kill zone” the size of a dime, the HotZot can be used in lawns and gardens to kill weeds that are directly adjacent to other plants you want to keep.
How do I know HotZot will kill my weeds?
Weeds can range from Canadian thistle through cockelburrs, goatheads, mullen and thousands of other unwanted plants. How can I make sure that the HotZot will be able to kill my weeds? The answer is easy – boil some water, put it in an insulated cup and then go outside and pour 1/4 cup on the crown of your weed of choice then come back over the next few days and watch the weed die. Occasionally an unusually robust, mature weed will require a 2nd application.
Note – Weeds such as blackberries, ivy, morning glory (field bindweed), etc. propagate by runners. Killing a single runner will have no effect on weeds such as these.
Why is citric acid necessary?
Adding citric acid occasionally is necessary to keep the HotZot working at peak efficiency by dissolving the mineral “scale” left behind when water is heated.With a “kill zone” the size of a dime, the HotZot can be used in lawns and gardens to kill weeds that are directly adjacent to other plants you want to keep.
How much will it cost?
Initially we expect the HotZot to retail for $200 plus shipping.
