New Garden Project

Hey folks,

After over a year of clearing out (including pulling down a workshop, brick BBQ, unearthing foundations of an old green house, replacing a hazard of an oil tank, and 4 skips of brick, stone, rubbish and concrete) our space is ready to start turning into a garden.







Here's the dream plan:







The reason for the split elevation is the fact in the future we'll have doors at the back of the house which will lead straight out - and so the lawn there wants to be the same level as the floor. However, the oil tank and fence at the other side of the garden is already higher up and would be costly to redo so; split elevation it is (plus we just think it looks nice)

I need some advice:

I want to try and do as much of this myself and the first thing I want to tackle is getting levels and a lawn sorted.

- What's the best way of planning out levels? String lines?
- I was thinking tilt the lawn towards the back corner for drainage and to slope water away from the house. Is there a good ratio for the amount of slope over distance?
- The soil which was under the workshop looks dead, cracks in the heat, and is full of stones. I've also no idea how long it's been covered. Could have been a decade.

My thinking is to simply remove the top few inches and replace with brand new fertile topsoil. Is that a good idea?



Thanks for your help!

 

Get a rotavator in the to turn the soil over, lay down some new topsoil and compost. Level it by eye with a rake or large length of timber by dragging it over the top

 

Thanks. Would you remove the existing grass first, or just rotavate that into the soil (bearing in mind I want to seed / turf a new lawn on top)

 

Thanks. Should I remove the existing grass first, or, is there any benefit just chewing that up and digging that into the soil?

 

Personally i would kill the current lawn with glysophate, wait two weeks to make sure everything is dead and then i would rotavate, re-topsoil and compost, then put down the new seed. It will give a nice new green garden, with one lot of grass ans not mixed grasses of which you dont know what they are…..

i had to kill and regrow all my back garden this year, after i found it was infested with couch grass……its now growing back lovely, with one type of seed and not a mash up of loads of grasses.

 

Ok, glysophate it is!

 

In image 3 of post #1, the difference in levels of the gravel boards in that corner suggests there is already a slope in the garden, and probably towards that corner.

 

A bit of an update on the garden project!

I sprayed everything down with glysophate which did a good job turning everything brown...except for one patch of green I missed. I'm now skipping the dead turf and an inch or so of soil, not only because the level of the garden needs to come down, but I want to give the garden a fresh start, so I think some new topsoil wouldn't hurt.

Before levelling, I'm thinking of digging a soakaway at the back for the gutter drains. Currently, I think they just run into pipe which is a few meters long then just ends in the soil - probably not the best way of dealing with drainage!

 

The more I discover, the more I think all the drainage needs to be redone. The garage gutter drain is far too close to the surface (and funnily enough I don't want the top of a pipe sticking through my lawn), and the gutter drain at the back of the house runs a few meters into a soakaway....which is full of clay resulting in no drainage







My thinking is a new soakaway at the back of the garden, and some bending pipe to take both gutters there. Think that's a good idea?

 

To assess your levels, the easiest way I know is to use a long clear plastic pipe with water in, (food dye is useful). Curl the ends of the pipe upwards, almost fill with the water and it will show the same level at both ends. Also useful to establish a gentle even slope on a pipe.

 

I haven't! I know nothing about rain gardens, so I'll do a bit of research. Thanks!

 

A bit of an update; I installed my first bit of 110mm drainage. Wooo! Just a temp solution to at least replace the pipe that was there and better take water away from the house.

 

Hello! Been a while but back with another update on the garden project. For the last few months, I've been sorting out the drainage by digging and installing (by hand) my first-ever soak away. I was quoted £3,000 for the work which was an absolute no-go, so DIY it was!





Hopefully this now solves the issues with the gutters and I can bury this all and move on from drainage issues and actually start getting in new topsoil and levelling.

I want a nice lawn!
