How do I make custom-made soil?

Choose any materials such as these and make the combination you like best.

Custom-made soil mixes:

  • 35% Blowsand with 65% Peatmoss.
  • 75% Sawdust with 25% Sand (clean)
  • 15% Perlite with 50% Peat Moss or Sawdust and 35% Sand (clean)
  • 50% Sawdust with 25% Styrofoam Pellets and 25% Sand (clean)

Blowsand is fine sand like that heaped up by the wind in sand dunes.

Perlite is bits of granite rock “popped” by heat. It is available at construction suppliers.

Sawdust is safe to use from almost all kinds of wood (do not use black walnut or scrub oak). Fresh from the saw or aged—either will work.

Tips

Avoid wood shavings. They are miserable to mix and plant in and tend to flatten into layers and sour.

Remember, the soil under your grow-box can be sand, rock, gravel, good soil, peat, clay or cement.

Tip of the Day

It's Spring Planting Time! For those of you in the Northern hemisphere who have winters, March and early April are the time you need to be preparing your soil and planting the hardy vegetable crops such as radishes, peas, cabbage and broccoli.

The freeze/thaw cycles of winter have broken up and loosened most soils, so as soon as it's not muddy, go in and give everything a good weeding with the 2-way hoe (see Tools). Weeding thoroughly this early gives you the upper hand, and is very important.

If you grew a Mittleider garden last year, your beds will be easy to re-make. Just apply Pre-Plant and Weekly Feed to the bed area, then till them in, place strings on your stakes, and re-make the beds.

Be sure to re-check the level of each bed accurately, since they may have changed a little. Do not be satisfied with anything more than 1" fall in a 30'-long soil-bed. Good Gardening!
