As a beginer to gardening and a new commer to the site, i think this advise is very helpful for me to build my first ever garden wall to hold my soil back. Thanks very much.

Love this. going to build two and put a bench between them. should be a lovely place to sit.

not very as I haven't the means to carry out such an undertaking
24/11/2011 at 15:28
Been looking all over the web for a guide, as this is exactly what I want to do! Anyone actually done this??
24/11/2011 at 15:28
Fantastic. These are really clear instructions. Can't wait for the spring to get started.

I'm new to this garden malarky but want to try this, although not sure about the curved bit....we'll have to see if that works out!
Looking forward to trying in few weeks :)

Asked at a local builders merchants and they recommended concrete blocks, NOT Breeze blocks as they will eventually rot, and must be kept dry, e.g. inside! So just check before buying! I plan to do this in a few weeks so watch this space! If anyone else has done this I'd be interested!

I Think I Might Try This I Will Do It With Those Old Victorian Stones Thoe

A great idea. A few points though, I would add a drainage layer before adding soil and a drainage outlet. Alternatively, I would only use hardcore where I'm going place the blocks, allowing the added soil to drain into the original topsoil. Does hardcore allow for good drainage?

great stuff thanks :)

Are you seriously suggesting that anyone can tackle this project? Whacker Plate? Cement mixer?
My husband (aged 70) built one with seasoned wood and six supporting columns. Surely that would be more within the reach of the average gardener?

This is a great idea. But practically there are problems. As one of the people who've actually built one of these - following the instructions - the design really needs a drainage outlet, or if you follow these instructions proper lining. While the wall looked fantastic for the first 4-6 weeks, I'm now having to deal with the issue of water penetrating through the render and through the blocks after the soil and plants went in. The water penetration is showing up as efflorescence (a white powder that shows on the surface of the wall). So I'd fully recommend that you seal the render or line the inside of the wall - and decide against "Only render halfway down the inside of the bed, as the soil will cover the rest. "

I've not fully stopped the problem. So I'd suggest other people considering the project do investigate this further. Prevention is better than a curse!

I'd also suggest if you are considering this project, seriously price up the soil you'll need to fill the bed - and then once (even after stamping it down) let the top soil settle before planting and then top up with more soil. You'll be amazed at how much soil you'll need.

We used ths a base to make a roraised rose border, 25' by 6'. nfortunately, it droesn;t dscuss the type of blocks to use. As myhusband has arthritis, he bought lighter blocks with holes in. Apparently these are for inside only.

Having cemented and painted the whole border,filled it with compost and planted over 20 roses, the whole thing is collapsing. The painted cement is falling off in chunks and bricks are falling down.

Any suggestions?

This project really does show an example of how not to do things! Sadly it sounds as though this ill thought out and detailed project is now going to cost sianpinnell both time and added expenditure to sort out.

No one in their right mind would lay blocks or bricks on a compacted footing/base.  A concrete footing is the correct and only method to use.

And why on earth was it suggested that "breeze blocks" were to be used. This is a major error on the part of the design and construction team. If you are going to use blocks, then the only ones to use are concrete. Anything else will just absorb moisture and blow apart with the first frosts.

Not allowing drainage is also another poor oversight.

These kind of errors really should not happen.

do I need a membrane down on concrete base,when making a raised bed.Thankyou.
27/03/2012 at 21:56

Dotty, if I'm reading your question correctly, and you are asking if you need to lay a membrane onto the concrete footing prior to laying 'concrete' blocks, then the answer is no you don't.

I really would strongly advise not using the example shown as project guide line. It is doomed for failure.

for the disable gardners

Any one have any thoughts on the raised beds or drawings giving me the correct size 

they should be . most of the work will be done by my helpers we will try to get a grant towards the cost of the beds, plus raffles etc bill the plot manager

I would like to build raised beds in my garden which is flagged and all my plants are grown in pots, very time consuming. Do I have to put a membrane between flags and hardcore, what would you suggest ?
06/04/2012 at 15:06

hi all,

sorry to be a little slow, but where are the instructions for the raised beds that you are all talking about.

thanks
