What Are the Benefits Of a Compost Sifter Screen?

A sifter screen can go a long way when it comes to achieving a clump and obstacle-free organic compost.

Basics Of Compost Sifting

There are a number of different compost sifter screen models out on the market. If you want to do it the old-school way, then you will need a wheelbarrow, over which you will be sifting the compost.

The other way is the hi-tech spin and wheel.

Whether you built your own compost sifter and a screen, or you decided to buy a premade one the process is not that complicated.

Once you have got your organic matter ready and you want to pot or replant with it, put it into the sifter and spin the wheel slowly.

As Mlgardener suggests the idea is to remove all the things that could potentially damage root growth, including bigger leaves, and clumps of dirt :

 

In Which Situations Is Compost Sifting Good?

By aerating the soil and removing clods you will ensure that the potting soil has a better water absorption rate, thus allowing your plants to grow in an optimal environment.

Chances are high that you are already aware of the many benefits that organic matter compost provides, so why wouldn’t you get the most out of it by investing a bit of time in screening/sifting?

Think of spring as the best season to perform compost screening, considering that most planting or repotting gardening tasks are done during that time.

How To Make a Compost Sifter Screen

As we have mentioned above, there are more than a few different compost sifter variations.

When it comes to DIY, we think that your best option is the wheelbarrow because it is easier to build, and it will reduce arm and wrist strain :

 

Using the wheelbarrow sifter is quite simple. Once you load the tray with up to 3 inches of organic matter, you push it back and forth quickly and lightly.

The idea is that the fine soil goes through the sifter screen and into the wheelbarrow while rocks, clumps, and debris stay at the tray.

What Will You Need?

In order for a compost sifter to be complete, you will need to build a frame and a tray (with screen). There are a couple of things that you will need:

  • Four feet of 1”x1” lumber
  • Four feet of 1”x4” lumber
  • Twelve feet of 2”x4” lumber
  • Eight feet of 1”x2” lumber
  • Fourteen 1-1½” wood/deck screws
  • Ten 2” wood/deck screws
  • Ten 3½” wood/deck screws
  • One 22”x34” piece of hardware cloth with a ½” mesh
  • Wood glue
  • Metal staples
  • Handles
  • Candle
  • Paint
  • Saw
  • Drill
  • Staple gun
  • Metal cutter
  • Sandpaper

Frame Construction

While this article focuses on constructing the sifter screen, you will need a frame that will keep it in its place. The first step is to cut the 2”x4” lumber into 36-inch long pieces (two of these).

Once you have done that, do the same, but for the 1”x4” lumber, make sure that the pieces are 27 inches long. Lastly, cut another two pieces of 1”x1” lumber, making sure that the length is 36 inches.

Screw together the 1”x4” pieces with 2”x4” in a cross. Once you have done that, glue the 1”x1” to the 2”x4”.

The idea is that the frame is around 22” wide and that the tray can be put on the 1”x1” lumber pieces (glued to the corners of the 2”x4”).

Screen Construction

The first step in building it is to put together the 2”x4” lumber using the 3½” wood/deck screws.

Once you have done that, customize/cut the hardware cloth to be compatible with the tray, but make sure that it doesn’t touch the edge.

The next step is to get the frame secured using metal staples, only to then screw the 1”x2” lumber pieces to the bottom and attach the metal handle to each side.

After that, we suggest that you paint or seal the wood surface. Also, a great tip is that you use a candle and rub it both at the bottom and top in order to ensure easier sliding.

Troubleshooting

The first thing that you should keep in mind is to have all the aforementioned items in one place. There is nothing worse than starting a DIY process only to find out that you didn’t prepare the lumber pieces or you are out of screws.

Also, you should make sure that the hardware cloth is made out of metal.
