I was going for maximum space and didn’t put to much thought into how deep my garden boxes needed top be. So I purchased the most inexpensive untreated wood I could find, 8′ x 8″ x 2 ” inch boards. Hi Debbie, You don’t say what your boxes are made of, but for maximum peace of mind I’d say impermeable plastic would be better than landscape fabric, which is usually porous to prevent waterlogging when used on the ground. I used to buy books and magazines but this article gives me everything that I need to know about my new garden. I particularly like when I get photos of planter boxes that have been built using my plans – so glad others too can enjoy the design. Another DIY raised garden bed idea using free, natural materials that you can gather in your backyard is this one from Instructables.
Raised beds do tend to dry out quickly so need plenty of irrigation, and if your growing medium is mostly garden soil then this will dry out much faster than if it was mixed with plenty of compost (or you could use bagged potting soil). Before you establish the bed, break up and loosen the soil with a garden fork so that it’s not compacted. Raised garden beds are made to order for those whose native soil drains either too quickly or too slowly.
The first layer should be green material such as green waste and the sod you removed when you were preparing the garden. You’ll need about 32 cubic feet of it. The blend that I used was 10 cubic feet of topsoil as a base layer the a mix of about 10 cubic feet of compost and 10 cubic feet of garden soil for vegetable gardens. A raised vegetable garden bed can be as high as a kite, as low as your toe and as many layers as you want to stack on. Wood that is pressure treated with Alkaline Copper Quartenary (ACQ) contains a very high level of copper and consequently, also appears green.
We like garden beds at Home Depot and Lowe’s, but they can be more expensive than doing it yourself, and they don’t always have that personal touch that you might want in your gardening area. Personally, I have had very good results with this blend, and these materials are all readily available at any garden center. If you have a lot of things to plant or don’t have someone to assist you, I suggest making several smaller boxes. Stock tanks, which are typically round or rectangular with rounded ends, are generally used to feed farm animals, but they’ve been gaining popularity in recent years as a great way to add urban chic to the garden.
The angled boxes are 10′ on the long side, 6′ on the opposite side, 6′ on the end and 2′ on the opposite end. Lining the inside of the garden bed with 6-mil black plastic may prolong the life of the lumber. You’ll need a chop saw (or something similar) to make all of the wood cuts, a rotary saw that’s designed for cutting metal to cut the galvanized sheets (we had to buy one at Home Depot, the cost was a little over $100), and a good drill with the right attachments for screwing in the wood and metal screws. Constructing raised beds from rock is a very easy DIY project for the average homeowner.
Update: After about a day, the plastic pots were beginning to sit cock-eyed in the planters, so I used a few scrap 2x4s and attached them to the inside of the planter with wood glue and nails. Raised beds tend to dry out relatively quickly, and are often used to make it possible to grow a garden where soil drainage is poor, so you should not normally experience problems with drainage in a raised bed. Of course, when you have earth permanently against a wood surface, you are not going to be able to re-treat it easily. I have a great project to keep you busy this weekend: pick a good sunny spot in your yard and build a raised vegetable bed!
The build process is the same either way, apart from the fact that with the bigger timber we screw them together rather than nailing. Cost per linear foot is cheaper than the expensive, naturally decay resistant wood and it lasts a lot longer. My husband painted the wood to protect it from rotting, first with a sealer and then with indoor/outdoor paint. This two-towered planter box bench serves to spruce up the outside of this garden shed and provide a bit of seating to enjoy your hard work by.
This allows 4 or 5 inches of the board to extend below the garden box to help hold it in place, and to keep the box from bowing due to the weight of the dirt in it. I used a 4″ x 4″ post for each corner of the box, and a 2″ x 8″ board for extra support for each long (10 foot) side of the box. Last year I worked very hard with my garden and it was coming along splendidly,and then one day I go the my garden and there isn’t a plant to be seen and there is a groundhog eating the remaining watermelon sprouts! If your garden is in a well-drained location, beds can be created by digging the topsoil out of the pathway areas — say, to a depth of 6 to 10 inches — and adding it to the planting areas.
In fact, conventional gardeners would be well-advised to reduce their garden area when converting to the deep-compost method, unless they plan to feed the neighbors or start a roadside stand! Some woods are softer and will breakdown quickly, but you can drench the insides of your garden boxes with safe and cheap linseed oil to help preserve them longer. Below I describe the method for building a raised garden bed that is two boards high, which provides good depth.
If you did use the wrong wood though, it will only be a matter of time and you could just deal with it now and replace with pressure-treated wood or rot-resistant wood more suitable for outdoor use. Keep an eye out for some of the more creative ways to make your planter boxes multi-purpose, including planter box benches and planter boxes that provide a little nighttime mood lighting. Cost: Depending on the size of your bed, cedar or redwood could cost up to $150 per bed; pressure-treated wood costs $75 to $100. A traditional garden laid out in narrow rows devotes over half its space to paths.
Although this looks like a meme, it’s actually a picture of a great idea: putting casters on your raised garden beds. For extra stability you can drive a wooden peg into each inside corner and nail it in place. With urban gardening and farming becoming more common and innovative, it’s interesting to see what kind of garden beds and container gardens pop up in big cities across the country. The dripper is totally diy and uses a glass pot lid in the rain barrel as a float. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper.
I have seen conflicting articles saying that it may be ok to use pressure treated wood after 2003 such as this one: , but I am trying to replace my chemical habits with good non-toxic ones. The water does drain straight through the table, but if you use a garden cloth in the bottom before adding the rocks and dirt, you shouldn’t have any loss of dirt making a mess. If you’d like to build this planter for yourself, click here to download the PDF plans Oh, and PIN IT so you don’t forget it! A typical garden is basically just an area of dirt with not much street appeal. Imagine if a man would go door to door and offer to build ‘victory gardens’ for us all.
It’s going to take awhile, but I think the new garden boxes will not only look better, but grow more food in the long run for my family. I plan to do a smaller garden box for my son, he’s a quite good gardener at 2 yo… Not as me, I killed plant. However, the water-soluble nature of these products means that they don’t chemically bond with the wood and can leach out. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain.
A reasonably level site is a good idea as well, and since it’s a fresh food garden try not to have it too far from the kitchen. Step 2. To build the bed, simply fasten the boards at the corners by screwing together in 3 or 4 places with 3-inch deck screws. The depth of raised garden boxes generally require at least 6-12 inches for the proper root development of plants. Once they were all leveled, we filled the boxes about 3/4 of the way full of soil.
Just remember that good drainage is important for a raised garden so don’t run the polythene sheet over the bottom of the garden. Linseed oil can contain toxic additives, so it’s best to avoid it. A wide variety of borate-based washes” exist to make wood resistant to decay and insects. I can’t even remember what kind of wood the boards were made of, but the total cost for each bed was somewhere around $20 – $25. The planter boxes themselves were gorgeous, they kept rabbits and other critters from munching on my greens, and I went for weeks on end without having to water.
We chose to make our boxes out of redwood, mostly because we could purchase thicker, more durable boards for less money. In addition, use treated-wood screws (porcelain coated or stainless steel) to build your flower box, otherwise you’ll be faced with traces of rust after a few years. We felt that these are a great fit for our yard, and the size of beginner’s garden we wanted to use.
I’ve had my pressure treated wood raised beds for my vegetable garden since 2005 and was recently made aware of the potential risks of using this kind of wood. But concerning your question, if someone was to use a pressure treated wood to make a garden planter…… you can isolate pressure treated wood by lining the inside of the bed with heavy plastic to prevent leaching of chemicals from the wood into the soil.
The base of the bed was turned upside down and filled with soil to create the main part of the new raised garden. The size is decent and works well for flower, vegetable garden or use for sandbox. Permanent enclosed beds, built to the correct height and width (usually about two feet high and three wide) make it possible to garden from a wheelchair. This year I built cedar boxes similar to how Ana White did them here Though mine were 50% more expensive each.
