I have been reading some posts on here and admiring some photos of well maintained plots. However, I have seen some pics with raised beds and some without. Whats the advantages?
-
Plenty, in fact, I don't think there are any other serious downsides than building them. :wink:
-
Thanks for the quick reply gobs, but i am a complete novice so will need a better explanation of the advantages please.
I'm waiting to get my first patch and would like to know the best way forward.

Upside, no digging, easy access, easy to weed, easy to net from blasted birds and a salad bed that was prolific despite the awful summer.
Downside, well there will be plenty of people along in a moment. :wink:

Unless your soil is bad - claggy clay or something - I wouldn't bother. You will end up doing more carpentry than gardening. You can get the benefits - less digging, closer spacing of crops etc by just having narrow beds that you don't walk on. Over a period of time, with the application of manure and compost, they will rise up.
But if you feel like having a go - make a couple and see what you think. I've got a small one in a grotty corner which I grow salads in and I inherited a sort of ramshackle one from my predecessor.
Always remember my mate's good advice: "It's only an allotment". If it doesn't work this year, you will know better next time.

Thats good advice Noshed , Raised beds are good easy maintenance etc.
The less digging the better , But you can have deep beds , A lot of graft
at first but will raise up over time. I have both sieved soil for the roots
is a good thing as i have stony soil.

Believe it or not, I found the plot as a whole was overwhelming, and weeding became a nightmare. Having it compartmentalised if you like, gave it structure and helped me to plan better, section off my weeding regime and help seriously think about future crop rotation. Then it rained last summer and I think I was probably a bit too smug when I looked at everyone else's waterlogged plots - I thought it was worth the effort. :D
-
I'm with Noshed and Painted Lady. I have unraised beds but I found shifting to a bed system (about 8 years ago I think) made manageability much better. Also the not walking on the soil made turning it over and weeding it much much easier.
As Painted Lady says raised beds drain better but the flipside of that is that in a really dry summer that requires more watering.
Up to you but it looks like we all recommend a bed system raised or unraised!
-

But once the soil tilth builds up, which it should do quickly since you're not wasting compost and such on paths, it will retain moisture better and longer. You're also working with a deeper depth of good soil. And if watering worries you, then mulch. :wink:

So from what i am reading, you would all advise, if possible to go with raised beds?

I'm in the middle of installing raised beds myself. My 'lottie is on the side of a mountain and really wants to be mountain, I have a 100% battle with couch grass and other weeds that ensure I spend all my time fighting them and not improving my plot. So, I'm going raised beds, weed suppresant matting inbetween with wood chip on top to form paths and mulching the beds to force weed seeds down. I've had my plot 4 years and dig it comletely every autumn and again in spring. Last year I was back to square one by June and very despondent. As much as I love my plot, I cant spend (and dont want to spend) all day every day weeding the thing. My advice is to build them and save yourself a lot of grief. I get tanalised timber for an 8'x4' bed for under £9. just my opinion, good luck.
-
Thanks, so is there a simple way to construct raised beds? What prep work do you need to do before hand and what do i need to do to keep weeds at bay?
-
You can make scruffy ones from old pallets - just drive posts in and nail the boards on. All you need is a bag of galvanised nails and some pallets.
-
im halfway through doing my beds, i bought 22 pieces of 6 inch treated timber that were 1.8m long along with a couple of treated 3x3 posts and some membrane to go under what will be the path for about 40 quid
-
I think its more a matter of personal choice. We started with raised beds, but are now going open plan. The main reasons were that there was too much wasted space, we like digging (and will need to for some time as we are so infested with nettles and brambles), and the fuss of building them and then replacing as required.
I think you can plant closer with raised beds and its good if the soil is clay. Downsides I have read about include more slugs hiding at the edges and less worms in them.
Why not try some beds and some open ground and see which you prefer?
-
That's a good plan
-
Downsides I have read about include more slugs hiding at the edges and less worms in them.
Worm populations were fine, slug population about same but yes they would have more "hidey holes" I suppose. T'other downside is an increase of ants nests. I knew there was a couple of ants nests in the wilderness and then I cleared it all .... now collectively all my raised beds is like Manhattan - each one is like a block and has its own population of ants. And they bite :shock:

if you use old pallets wont they only last a year or two???

I'm lucky insofar as I can get good treated wood from work. I have gone with the raised bed system because I have a very bad back that won't put up with much digging at all.
The raised beds mean I dont have to bend over too much.
The only disadvantage I have come accross, is that they can dry out a bit quicker than normal beds on the plot. This will become less of a problem as each year goes by if more and more organic matter is introduced into the beds. the organic matter improves the soil's structure and improves it's water holding capacity.
They do make the plot look tidy, it's not so daunting a task to do the weeding (do a bed, have a cup of tea, do another bed....and so on) :wink:
-
Well i think the plan for me will be go with what i have got at first, assess what problems i have and then re-evaluate. Where i live in Dunstable the soil is very chalky so i will need to be nosey at the site (when i eventually get allocated a plot) and see who is doing well with their bed type.
Anyone else have chalky beds to contend with?
-
nosey is the way forward.
If it does well on their plot, then it should do well on yours :wink:

We are going to install raised beds in our garden over the next couple of weeks. Whilst i see the point about not walking on the beds I think the kids would run full tilt into them. I am in the process of getting timber - can you use treated timber? We were worried about the chemicals and the food? What sort of treated timber do you use?

There was an in-depth discussion on treated wood a while back, if you search you should find something in one of them technical sections.

I have gone along with the raised bed system and have 6 of them 30 feet by 4 feet, I use them in pairs ie: 2 for brassica,s, 2 for legumes, and two for roots & potatoes, to work a 3 crop rotation plan. I made mine out scaffold boards that gave a few coats of preservative to. When I installed them I spaced the board support posts 6 feet apart. this gives me a 30 * 4ft bed but it is in 5 sections (5 * 6ft = 30ft) and it makes it a lot easier to plan my seasonal planting plan as i know what space is needed for each crop and how much of the crop to sow so this saves on excess plants being grown.
All in all I,m glad I made the choice of a raised bed system.

I'm SO jealous, Skiprat. I had the best part of my old plot bedded up and then we moved. :cry:
Got to start all over again I'm afraid. It's all going quite a bit faster this time though, I made all the mistakes first time around. :D
-
We have for and against :) on our site, but most of the newcomers favour raised beds. I have put some of what I consider to be advantages on our blog.

Thats the problem whe you move RTR, but at least you have the experience to repeat the set up that you had at your last address. I wish you the best of luck in your endevours.
