Question
I have dollar weeds (and a few others) in various areas throughout my lawn.  I saw your comments regarding putting sugar on my lawn to help microbes that enrich soil.  

How often can I put the sugar on the lawn? And do I put it just in the area of the weeds?

Thanks.

Hello Bob;
Sugar only works if you switch to an organic program.
If you continue to use chemical fertilizers etc, the microbes will just be killed when you apply the chemicles, and you will be right back where you started.
The sugar keeps alive the beneficial microbes that enrich your soil.
Weeds like poor soil and will not thrive in rich soil.
Make rich soil and the weeds will not like your soil. After the soil is very rich, the weeds that seed into your yard by birds, the wind etc, will germinate and try to come up. any that do come up will die out just like good vegetation will die out if there are NO nutrients in the soil.
In the same way that too much fertilizer will kill the good plants, very little fertilizer( nutrients) will kill out the weeds.
What some people call flowers, others call weeds.
what most of us call weeds ( some flowers are included in this group. Like Nasturtioms, clover, wild violets etc)are plants that require very little nourishment, and will not thrive if they get too much. Roses, pansies, grasses etc require more. so when there is enough nourishment for these plants, there is too much rishness for the others to live.
for some reason though, chemical fewretilizers also feed the weeds and make them gro, where the naturl nutrients make only the desirable plants grow.
Fot the sugar to work right ( or dry molasses etc) you need to go on a fully organic program.
The sugar will revive a lot of the microbes, byt the next time you put down any chemicals, they will die out again.
If you stay on an organic program, the microbes will work round the clock all year round, enriching the soil.
