Rebuilding a Bed Garden, Raised Beds

How to rebuild or make a new raised beds. Even with the plants growing. It’s best to rebuild before you plant but it can be done with plants in too.

Want to get started gardening, but the soil conditions at your house just aren’t ideal? That is exactly what we faced at our home. The soil is so clay-like it almost smothers the roots of the poor plants.

When we decided to have a garden, we knew we would be building raised garden beds. We built our own beds with lumber and screws and were happy gardeners.

How we rebuilt our raised garden beds while the plants were growing.

Fast forward many years later and our raised beds were looking pretty bad. The wood was rotting right off around the screws and we knew, really soon, they would just fall apart. We knew the raised beds needed to be replaced, but it was already late in the season last year. So I just went ahead and planted our garden.

We knew the raised beds needed to be replaced, but it was already late in the season. So I just went ahead and planted our garden.

But my husband and our neighbor, gotta love helpful neighbors, found a good deal on cedar boards for our garden beds. Our neighbor picked up the wood on his way home from work, we have great neighbors, and we now had the wood to rebuild the beds, but we also had plants growing.

Our old raised garden beds were in really bad shape. They needed to be redone.

The wood on the old beds was so rotten, we thought surely we could get them off and rebuild them with the plants in place. So we set out to tackle this project.

In case you need to rebuild your raised beds, I thought I would share what worked for us. Even if you have to do the rebuilding with the plants in place, you’ll know how. Although, I hope I’m sharing this early enough, that you can get them rebuilt and then plant your garden.

How to Rebuild Raised Garden Beds

The first thing I did was water really well. It was hot the few days we were working on this project, another reason to get to this early, avoid the hot sun. I really overwatered a few days before we started.

Having the soil nice and moist helped to hold the soil together as we removed the old boards.

Tools we used to take apart the old raised beds without disturbing the dirt.

Removing the old garden bed boards wasn’t too hard. I only needed to use a drill to remove the screws, a pry-bar for those difficult to remove boards, and a pair of gloves. Yes, this job was pretty dirty, so be sure to wear gloves.

After removing the screws at the end of the boards, I carefully pried the board away from the soil. In most cases the boards were rotted enough they just kinda fell apart, as I pulled them away.

The soil was moist enough that it held together nicely. We tried not to touch the soil until the new boards were in place.

When replacing the raised bed boards, be sure to water heavily before removing the boards. All the moisture will help to hold the soil together.

Wooden Raised Beds Supplies

We opted to go with full length and height boards this time. We used one huge board running the full length of the bed. We also purchased 12 inch, wide boards. We didn’t want to have to screw two boards together to get the right depth this time.

Since that is where our beds started to fail first, even though we reinforced them.

Even the extra support for the sides was rotting away.

After the old boards were removed, it was time to level the boards on each side of the garden. Our garden plot is on a slight downward slant. Well actually it slants two ways, so we dug down into the dirt to get the boards level.

We didn’t bother with this step the last time we built the beds, but we had some pooling in the garden beds. This time we took the time to level them out.

Level the Garden Beds First

We leveled them not only with the ground but with the bed next to them. This was quite a task. I felt we really didn’t need to do this leveling. But I’m glad we took the time to level them, they do look quite nice and no pooling of water, in the garden.

The huge screws we used to hold our raised garden beds together.

After the boards were level, we used huge screws (affiliate link) to attach the boards at the ends of the beds. We reused these screws from the old beds. The screws were really quite expensive and it took some work to remove them from the old boards, but it was well worth it.

I think those screws when we purchased them 6-7 years ago, were $50 a box and we needed two boxes at the time. They cost as much as the wood. But they have lasted quite well, so they were worth the cost.

Attaching the End Boards to the Raised Garden Beds

How we screwed the bottom board onto the side boards with the huge screws.

Once all the boards were level, it was time to attach the end boards to the side boards. When screwing the end board to the side boards with those long screws, there is a chance the screw will try to pop out the side of the long side board.

Be sure to be in the middle of the long board end, when you start and try to keep the screw as straight as you can when screwing it in. We had to go really slow to keep it straight, but it was worth the extra effort. We didn’t have even one screw come out the side.

Once the new beds were in place, I needed to move a few plants that were right on the edge. We needed to add a little fill dirt, here and there, but that was it. The garden beds were now rebuilt and we didn’t lose any plants.

Tips for replacing the old worn out boards on your raised beds.

Tips for Rebuilding Raised Garden Beds

✳︎ Before removing  the boards, water the beds well. It helps to hold the soil in place.

✳︎ Remove as many screws as you can before trying to pull the raised bed boards away. This makes removing them easier and reduces the chance for the soil to be disturbed.

✳︎ Gently pull the loosened boards away, prying only when needed. We found having a person at each end of the board to peel the board away from the soil worked best.

✳︎ Remove any expensive hardware that is salvageable. We found most of the screws in our raised beds were still good and we saved money by not having to purchase new hardware.

✳︎ Level the new boards with any slope in the ground for watering without pooling. Also level the beds from one to another for esthetics and for ease of adding any watering system that goes from bed to bed.

✳︎ Once new boards are in place add more soil if needed to fill the beds more fully.

We used cedar to build our raised bed. They should last quite a while and look great too.

Tips for Making New Raised Beds

Map out your area with string or cut into the grass or dirt with a shovel to show where your beds will be. Also note any slope to the area.

Remove any grass or weeds that are growing in the new garden plot area.

Place a layer of cardboard or newspaper on the bottom of the garden bed area. It will eventually rot away but will deter any grass from growing up into the beds too.

Measure the length and width of your beds, twice, then cut boards to fit. We found, that it is best to have the boards at the end go all the way across and cover the cut ends of the long boards.

But you can also make the long side boards go all the way to the end and then place a smaller end board between them.

Once you have your area prepped. Place your boards and check to see if they are level. If there is a slope be sure to build up or dig down until each of the boards are level.

After all the boards are level, line up the screws you will be putting into the boards at the end with the middle of the long side board. Go slow as you are screwing them in to keep the board end from splitting. Also keep the screw as straight as you can while screwing it in, this will keep the screws from coming out the sides of the boards.

Fill the new beds with a mix of compost, peat moss and vermiculite. The vermiculite will help to heat the soil and make air pockets in the soil. The peat moss will help to retain moisture and the compost will feed the plants. I also added a little top soil to ours for a good balance. You can use potting soil, if top soil isn’t available.

It’s easy to think about skimping on the soil when filling the beds because it can take a lot of soil to fill them. But the quality of the soil can really determine on how well the garden grows. The soil isn’t the area to skimp on.

 

There you have it, how to rebuild raised garden beds, even with garden plants growing. Although I would really recommend doing this job before you plant your garden, it can still be done while plants are growing in the boxes.

  1. This was a great post. We have to do the same, but got the wood last fall & to many things happen all at once, and we now are going to be tackling this project very soon I hope.
    Thank you Shelly for sharing. I always enjoy reading what you post!!!!

    1. We always have a long to do list in the garden around here too. I understand hoping to get to projects and it doesn’t happen. We were hoping to replace a section of fence this past fall winter but here is spring and it still needs to be done. We’ll get to it eventually. 🙂

      I’m so glad you enjoy the blog, Anne.

  2. I wish this helped but, it didn’t. My raised beds are actually RAISED on cinder blocks. Any ideas how to replace the boards on these. The beds are about 10 yrs old. Thanks.

      1. Hi ya Shelly….
        There’s a 2×4 frame that rests on cinder blocks. (This was definitely over kill for our raised beds but, these were built 10+ years ago. We had 12 raised boxes originally and we are down to the last 4 due to rot.) Then there’s a floor of short 2×4 stretching across side to side. Then there are 14 foot 10×2 that holds the soil in place. Not sure I am describing this well enough. And, this all sits on top of 4 piles of cinder blocks. Oh and the frames are just sitting on the blocks. Weight holds the whole thing in place. Overall size is 14 foot by 4 foot by 10 inches deep. Hope you could understand this….
        Thanks.
        Phyllis
