Removing
Turf - How to...
Very
often when putting new plants into the garden or planting up a new bed,
tree, shrub etc. the first step is to remove some turf to make way for your
new introductions. Removing existing turf is hard work, but if you follow
this technique, it becomes easier than the way in which I've often seen
people try to deal with it.The first thing to appreciate
is that you don't need to dig down very far, grass is a greedy plant, but
it does this by intercepting water and nutrients as they are added to the
soil. there are some deep roots, but most of the plant is in the top couple
of inches of the soil. So you only need to scrape away about an inch of
soil to remove the grass completely, if you do this it won't be able to
grow back again.
Step one is to use a spade or lawn edger to cut through
the grass a line that limits where the edge of your new bed is to be. You
might be able to do this by eye as I am here, or you may want to use a straight
edge or string and peg for circles. If you need to mark the grass out use
flour, it's non-toxic and temporary, being brushed or watered in quickly.

Once
you've marked the line by cutting through to about 2-3 inches down, insert
the spade and then tilt it to cut forwards at a depth of about an inch under
the soil. The spade should be turned to become flat. If you're right-handed,
then your right hand on the spade handle will supply the effort to do this
while your left hand steadies the spade. A series of short sharp back-and-forth
jerks are most effective to get the spade cutting the soil and grass roots
rather than a continuous force.What you want to
avoid is digging great clods on earth up with a bit of grass on top, this
is very hard work and removes large quantities of soil that you then have
to do something with - and probably replace too.

Once
the spade is horizontal, continue the stabbing motions to go further under
the existing turf. Once the whole spade is under the turf and horizontal,
use the "heel" of the spade - the part of the blade where it meets the handle
- to keep it steady and determine the depth. |
Ideally
the soil should be fairly moist, not dry so it's hard, and not wet so it's
sticky and difficult to force the spade through. You do need to be reasonably
strong to remove turf this way, but if even if you're not, a small area
for a tree or shrub can be stripped in a relatively short time - it's very
important to cut the edge as in the first step, so that you get the edge
to the area that you want. |
When
you've gone about one or two spade lengths under the turf, tilt the spade
sideways or front to back to rip the turf you've separated and rip it off
from the rest. Repeat until you've done it all.
Removed turf - you'll have loads of this, pile it
up out of the way somewhere with the grass side down, water it well with
several watering cans worth and cover with old carpet or something and weight
it down - bin bags at a pinch. In 6 months it will be ready to use as a
mulch or to dig into the soil. The more grass in relation to soil you had
the better.

Other methods:
Weedkiller - use a glyphosate containing weedkiller to
kill grass in the area you want. Glyphosate is neutralised on contact with the soil
and so what doesn't fall on plant leaves won't cause any damage. Make sure you DON'T
USE PATH WEEDKILLER as this stays in the soil and carries on killing any plant life
for months after application.
This will take 2-4 weeks depending on time of year and dead grass
needs to be dug into the soil before planting up. I don't like this approach as
it's messy, an unnecessary use of chemicals and while low effort, you need to wait
before you can start planting. Good for large areas though, especially if you have
or can hire a rotavator to dig it all over afterwards.
Turf
stripping machine - These are petrol driven large lawnmower sized machines that
have 4 wheels and a square U-shaped blade that vibrates rapidly
back and forwards an inch or so beneath the soil, so separating it from the turf.
They do the same sort of job as the spade in the manual method above, but are powered and so much easier. They are still quite an effort to use however and can
be heavy to manoeuvre around, I have sweated mightily while wrestling one of these
machines around gardens. If you have a large area to strip they are invaluable,
hire them by the week, day or half day from tool-hire centres.
If you want to re-lay the turf you have lifted, you could hire
a "professional machine". The most common turf cutters like the one in the picture
result in turf that is rather messy and can't really be re-laid again, it's best
composted as it's all chewed up in irregular sized pieces. Professional turf cutters
are a little more expensive, though not a lot - maybe £75-80 a day as opposed to
£60-65. They are larger and heavier, but most importantly, they can remove the turf
in rolls that are able to be laid again elsewhere rather than having to deal with
the lifted turf or buy some in, so it could be the most economical deal. If you
do use the turf elsewhere, then plan things so the lifted turf has the minimum amount
of time before it is put down again - ideally immediately, certainly within 24 hours
or up to 48 hours if you don't mind it looking ill for a while.
