Tall Raised Garden Beds

The 21 inch high raised garden bed kit comes from our deluxe range and is the tallest raised bed we have to offer. Quickcrop's deluxe raised beds are all made from thicker 1.25 inch thick timber boards with stout 4 inch corner posts. The posts have metal fixing brackets on them and the inclusion of these is what makes Deluxe raised garden beds so sturdy when assembled. They will last more than 8-10 years of vegetable gardening and are our longest lasting and best looking raised bed.

With these timber flatpacks you can make your own vegetable garden, their natural wooden finish makes them an ideal addition to any back yard, garden, polytunnel or allotment. The quality is such that they can be used and re-used year after year. The solid design of a deluxe raised planter bed lends a certain extra durability that will help them withstand years of being worked on, repeated movement, emptying and refilling. Click for more information about raised vegetable beds.

All the timber we use is treated to last longer, the treatment used is certified by the soil association as safe to use with organic food crops so no worries there. We source high quality timber and have it cut to size and then treated at our local sawmill. Most other raised bed manufacturers treat their wood in bulk and then cut to size, this leaves the ends untreated and they will tend to suck up water and warp or rot way sooner than they should. With a 21 inch tall raised garden bed you can grow any fruit, herbs, or vegetables including root crops like carrots, parsnips and potatoes as well as shallower root vegetables like salads, cabbage, beetroot, peas and beans. The kit will be shipped in flatpacks and is very easy to assemble, all fixings required are included as well as full assembly instructions.

We started to put this raised bed together when we realized we had a whole packet (16) screws missing!! Very annoying as we live nowhere near a diy store so we then wasted 2 hours doing a 34 mile round trip to find screws. I see the previous reviewer had the same problem. My advice would be to check you have everything don't wait until you're ready to start assembly. We would have given 5 stars finished product looks good.

Looks well, easy to put together. But missing a pack of screws. 2 of the posts have splits running through them so will have to reinforce them. Putting the metal elbows on the inside (contrary to instructions) gives a better-looking finish.

I am starting my first vegetable gardening. I am interested in a 2x Deluxe 21" 6x4 beds. How much soil will it take to fill to maximum depth? 1 tonne for the two beds? I would like to mix with your compost - would I need a bag for each bed?
Answered by Andrew

Hi Julie. Thank you for your question. The 21" beds 6ft x 4ft take a lot of soil to fill and to be honest need 1150 litres of soil to fill each one. That said you only need good growing compost in the top 12" as in this depth of soil you can grow any crop. Each of the tonne bags we supply is 850litres

if I got a 6x4 raised bed, how many litres of soil would I need to fill it.
Answered by Andrew
on May 10th, 2016
Hi Ian. The 6ft x 4ft x 14" high bed takes 790 litres of soil to fill it. The 1 tonne bags we sell fit this perfectly.
Asked By Robert
on February 06th, 2016
Would you suggest lining the beds if they are going on to a soil/clay base? I am thinking of using 2 x 6x4 21" deluxe beds. Thank you.
Answered by Andrew
on February 08th, 2016
Thank you for your question Robert. You don't need a bottom liner for raised beds that are going on to soil and it is better not to have one. This will help the worms etc come up through your bed and aerate the soil. Also any of our beds over 14" will have deep enough soil for not weeds to come up through.
Asked By Mrs Scate
on March 05th, 2015
hi please can you tell me how long you anticipate the premier raised beds will last versus the deluxe raised beds? Do you suggest they are lined if placed on patio? Thank you.
Answered by Andrew
on March 06th, 2015
Hi Mrs Scate Both the Premier and the Deluxe beds will last over 10 years, they use the same timber. I would suggest using a piece of mypex liner for the beds if used on a patio as it will prevent soil being washed out through any spaces between the patio and the base of the bed (if the patio isn't completely level). I hope this helps Andrew
