My backyard has five feet of land which is full of grass. Recently I used vinegar on the grass per your tips on your website. The problem is that I don’t get enough sunlight in my backyard. Will the vinegar still kill the grass? How often do I need to spray the grass with vinegar?

The acid in the vinegar is what kills the plant more than anything. If it is a tough plant, it may take several applications. I would apply it every few days until they are dead. If there are no plants in that area that you wish to save, I would recommend boiling water. Pouring this on the plants will kill them instantly.

Preventing Weeds in Soil

I have a planting bed that had lots of weeds – especially after a new load of cypress chips were put down. I removed the existing liriope and visible weeds. Now there is soil and chips. I want to put in new plants. How can I treat the soil to discourage future weeds? How long before new plants can go in? I’m in Cocoa Beach, FL.

Weed Trees

I was told most weed trees will die if I cut down below the crown as long as they are young enough to get my pruners around them. Is this true?

Not necessarily. Many will only produce additional suckers below the cut. Pulling or digging them up is often just as easy and all of the roots will be obtained this way.

Getting Rid of Goat Head Sticker Grass and Other Weeds/Grasses

Is there a spray I can use to rid a play area of goat head sticker grass and other weeds/grasses, including killing the seeds?

Round-up is pretty all inclusive when it comes to killing every part of a plant. If you are looking for something more organic, boiled water will do the same. But be aware, both of these will kill any plant that it comes in contact with.
