Digging up turf for new lawn has lowered height of my garden

Hello, I'm delving into the world of gardening for the first time and I've hit upon a snag which I can't find a good answer for googling around, so I was hoping someone here would be able to give me some advice :)

Last year I purchased my first home and with it a decent sized garden. The garden was in a terrible state: masses of weeds and brambles and grass so long is was effectively a meadow. Due to other things getting in the way it's taken until this year to deal with it. After killing of the brambles and most of the weeds using glyphosate and then trimming back the grass I concluded it was going to be too much work to tame it and have dug up the turf, clearing it to place new grass seed down. However I'm now uncertain how to proceed. 

The issues I'm hoping to get advice on revolve around the fact that in digging up the turf I've lowered ground level by about 150mm. I've got a few concerns about this. First of all, if I don't raise the ground again my garden will be lower than both the gardens on either side. Is this a bad idea? I'm worried the other gardens will then drain into mine, turning it into a puddle. That said, drainage in the area seems good over all and despite recent poor weather I've not seen any water pooling in my garden.

Secondly, one of my neighbours performed the same garden overhaul as me a couple of years ago and put in a hedge along the border between our gardens. In doing so, he also tided up the grass about a meter into my garden so the hedge had room to grow. As his garden and that side of my garden were less chaotic, he managed to tame the grass without cutting up the turf and as such I have a meter wide section of the garden which will be 150mm higher than the rest. This runs the length of the garden which is long and thin--it's eating a meter into the ~6m width--so I'd ideally like to avoid having this section raised. I'm not sure how to deal with it however. One possibility would be to just dig up the raised section but it's close to the hedge and I'm concerned I'll accidentally dig up it's roots. Is that a risk? The hedge is still young less than a meter high.

Both problems can be rectified by simply buying top soil and filling in the area. However, it's approximately 6.6m x 25m, which, at 150mm depth, would mean approximately 25 m^3 of soil, or 40 metric tonne bags. That'd be £3000 which, unfortunately, is out of my budget by about a factor of five. 

Is there an approach I can take which will keep my garden as level as possible while keeping costs down and avoiding waterlogging my garden?

    What are you planning to plant in place of the removed turf? Just grass? Have you considered any other options? For example, you could make slightly raised border along the side without the hedge, bringing the surface up to the level of the neighbouring garden. And you could plant some shrubs into the raised ground on the hedge side with some wildflowers between and not mow it. Then just have lawn - or a mix of lawn and paving, perhaps, in the middle where you've taken the turf up. Then if you do find you have a drainage problem when it starts raining in earnest (unless you're in Scotland or N. Ireland, in which case it probably has already), the solution will be entirely in your own garden, such as land drains along the edges of the raised bits or different surface treatments.

  • What did you do with the old turf? Have it removed?

    I'm just planning on just sticking down some grass seed and adding a similar hedge to the other side of my garden. I'll probably want to do more with it in the future but it'll probably won't be too much as I want to keep it as easy to maintain as possible. Paving would be easier of course, but I like the idea of having a grass lawn more. The hedge I was less fussed about, but since I've got a hedge on one side it seemed untidy to not have it all the way round haha :)

    At the moment I've just got it in a pretty hefty pile down the bottom of the garden. Planning on disposing of it, or possibly attempting to compost it depending on if that's not going to be too much effort.


    I've done a bit more shopping around and I've found a place nearby that does a tonne bag of top soil at £50 rather than the £75 I was previous pricing at. I'm considering buying enough to mostly fill in the drop (perhaps 100mm rather than the full 150mm drop) for say a third of the garden and leaving the rest until next year when my budget will hopefully be a little less tight. Reckon that might be the best approach?

    If you leave it all until next spring the interior of the pile might have broken down enough to spread back over the area (you could take out any bramble roots etc as you go) - then you would need less topsoil, just a thinner layer on top.  It's fairly important that whatever you fill in is the same across the whole area. A difference in water retention/drainage or fertility will show in the grass growth in the long term.

    I had a loose-load of 25 ton of topsoil delivered 2 years ago, that cost £500/550 (can't quite remember). I got it from Silverton Aggregates - very good stuff too

  • My style would be to keep it local. It is a bit of a pity to have a huge load of turf removed and get a new load of top soil in, although I appreciate it will lead to results faster, and you have quite a large area. I envision turning over the turf and covering it with cardboard or plastic and let insects do the work, but this is probably not practical at this stage (and the brambles could still be problematic). However, you could use your turf to make some elevation differences in the garden. I would not worry about puddles too much, unless perhaps you want a large new lawn. If you do some serious gardening, improve your soil with organic content (over the years) it will all be fine. The Wildside nursery has a garden with artificial elevations (digger-made). I haven't visited it yet, but I've read the book by the Keith Wiley, the author. This is the garden:

    Unless you plan to play Crown bowls on your lawn, by far the easiest thing to do is just blend the raised bit into the rest of your garden. Just rake it all out, obviously not exposing the roots of the hedge, and blend it into the 'flat bit'. If your garden has a very slight slope at one side, what the heck. 6 inches is not a lot to worry about. Once the grass is down  and growing you will hardly notice it.

    First i think you worry too much. Gardens are odd ball places with various levels. Taking out the grass near the hedge wont affect the hedge. you can do it if you want.
    Second, seeding a lawn, though cheap can be difficult. Birds love the seed, it's difficult to spread it evenly and weeds grow up at the same time as the grass. A better alternative (IMO) is turf - a (real) grass mat from your local Homebase or many other suppliers. It can be got cheap, but make sure your not buying the local farmers meadow.
    Simply lay it on a flat surface and keep it wet until established. It's much easier than carpet to cut to size and you can literally tear and dump bits in tricky shapes and corners. it will increase the height of the lawn, which you want, and give you a weed free uniform finish.  
    If you decide to grow shrubs near hedges, leave some room between hedge and shrub, because you will need to cut the hedge separately or else the shrub and hedge will merge. Shrubs grow at different rates to hedges and both can be a bit manic.
    As for your lawn having puddles, don't worry too much. You may even  be grateful for pinching your neighbours precious water in our drought like summers. The usual reason lawns puddle is because they are not arieated. All you do is get a harden fork and go over the area (when it's wet is far easier|) digging the prongs in and pulling them out. Do this as close as possible, probably about one set of holes every four inches. For bigger areas you can hire arietors. 
    Lastly most laws eventually become mixed with weeds - buttercups, daisies, clover.. One can see this as beautiful and simply not worry about it. It all mows!
