Question

hi i need a solution.i have a massive garden with grass growing so high and so nasty the name given is crab grass i believe but after a week of cutting i can tell in some places that it starts to grow again which is a big hassle i need help how to kill all grass so i can replant new grass seeds or turf

Answer 1

Use glyphosate based weedkiller. Roundup is one name. It is the only one that will kill the whole weed/grass and dosen't harm the ground. The fast weedkillers only kill off the geen bits and the roots survive to grow again.

Answer 2

The best way to do it without poisoning the soil and making you have to wait forever to start planting is to -

Cut everything back as much as possible- get as much of the weeds out as you can.  Then get a big plastic tarp and lay it over whatever area you want dead.  Stake it down so it doesnt blow away and let it sit in the sun.  It will usually only take about a week to kill everything.  If you really want to be sure its gone, Dig up everything you see afterwards and then water heavily for a couple weeks.  Anything that sprouts should be immediately pulled out and killed.  

Then youre ready to plant in just a couple weeks, not years.

Answer 3

The best way to solve this problem ist to speak to an expert gardener.

Answer 4

The problem here is that the situation was neglected and now its gotten out of hand.  If it is that chronic your only choice is to dig it up with a shovel and re-seed. There are sprays geared towards crab grass  but  you will have to use repeated applications which is  toxic to the environment. The residual from these sprays are lethal to new grass seed.  So you have no choice but to remove the grass and put down the seed.

    Very often people with this problem -on a large scale- option to hire a landscaping company to bring in sod- that is pre-grown grass. They literally roll up the sod like a rug in 2 foot widths then they unroll it in your yard. It will look spectacular when its all done. As you might have guessed, this can be expensive but the option of you removing your crab grass can be very tedious and grueling.

Answer 5

you can do it cheap. get a sprayer fill with lots of salt. fill with water and spray on plants. maybe a few tb sp to 1 gal water.

Answer 6

Check at your local garden supply store. They have several product which are designed to kill everything in their path, then quit working after a period of time so you can plant what you really want.

Answer 7

Depending on where you live and what kind of grass you want to grow, this is best done in the early spring, BEFORE grass starts to grow again.

In your case it sounds like it would be best to tear up the grass you have, till the soil to aerate to ground, add a pre-emergent herbicide to the soil to prevent weed seeds from sprouting.  Then plant grass seed a month or so after the herbicide, in early spring.  You can then cover the grass seed area with a layer of straw to prevent the grass from getting eaten by hungry birds, and later to keep the grass from drying from the sun.  Young grass will need lots of water to get started.

I pull crabgrass here by hand, but I also don't have as much as you do.
