Wind break feature

We have a new garden! Lovely blank canvas.
We also have huge pile of sub-soil from building work on house.
I am planning to create a mini earth wall dividing veggie garden & lawn area. It will probably be maximum 3 ft high with a flattish top. Definitely not straight, maybe varying heights too. There will have to be one gap to walk through.
I'm planning to plant the slope (lawn side) with perennial flowers, wild flowers and herbs to make a backdrop to garden.
Several bits of advice needed :
Will I need a framework roubd which to build the 'wall'. Maybe wood? Single posts or like a trellis?
Will the wind go over the top and hit my deep beds the other side?
If so , should I plant a living hedge or put up a fence at back?
Any comments ? Ideas? Has anyone ever done this sort of thing?

 

Any pics,sounds a nice project

 

We're taking photos as we go, but cannot yet transfer them to this site. When my daughter visits she'll show me how to do it. Sorry, I'm not very proficient with the computer.

 

Hi Cherrywilows! It sounds like you have got a plan for a lovely garden. As to you questions, the main problem you will have with the soil wall is preventing the soil being eroded before the plants have chance to establish, especially if you live in a part of the UK that gets a lot of rain or is exposed to the wind a lot. It may be an idea to cover the wall in a membrane and plant through that. The wall will deflect the wind up and over, but if where you live is exposed area, slowing the wind down rather than deflecting is the best option. Tall grasses can be quite effective and may be a good idea if the soil wall you build hasn't got much topsoil as they are shallow rooted, but you may need a temporary wind screen, using mesh and posts to allow the plants a foothold before they have to withstand the elements.
Pop up some photos when you can, it sounds a lovely idea!
