Prepping for the Raised Boxes

  1. I cut a strip of the Dewitt 20-year Weed Barrier and lay it on the bottom of the raised bed. Doing so will prevent the mole and and rats burrowing a tunnel and into my raised boxes.
Planted daikons from seeds in this raised box.
I planted three daikon varieties in this box.


2. The layers of my pot/raised beds soil starting from the bottom:

  1. Fine pine mulch from Mulch for You
  2. Food scraps: fruit peels, veggies, crab and lobster shells, fish scraps
  3. Vegetable and fruit scraps
  4. Mushroom compost
  5. Potting soil mixture of perlite, Kellogg’s Potting Mix, peat moss, mushroom compost
  6. Crushed crab and lobster shells, worm casting, and some more peat moss mixed in the top six inches of soil

I have done this before and noticed a big positive change and difference using this prepping method compared to just using bags of potting mix at the big box store. The bagged potting soil by itself seems to dry up so quickly. The combination above provides natural fertilizer, calcium, root knot nemotode preventative, and medium to hold in nutrients and moisture longer.

Adding the crushed crab and lobster shells into potting soil for edible plants that’s proned to root knot nemotodes helps with prevention. It works great for cucumbers, tomatoes, and chili pepper plants. I plant all chili pepper plants in a 15-gallon pot.

Prepping Potting Mix for my Potted Fruit Trees

I recently learned about the importance and necessity of providing the appropriate pH level in the soil for trees and plants. I even bought a pH level soil tester.
