Old soil in raised bed

After a season of growth the soil in this raised bed is a couple inches low.

Top it off: If the level of soil has dropped, add fresh planting mix also known as potting soil. Ideally, the soil comes to within an inch or so of the rim of the planter or raised bed. Use a fork or hand tool to blend the new soil into the old soil.

Fertilizer and Compost Plus

All-Purpose Fertilizer and Booster Mix

Recharge it: Measure the square footage of your raised bed or pot to figure out how much of the two "secret ingredients" you need for your bed.

  1. All-Purpose Fertilizer: Use 1/4 cup per square foot. A slow-release, 5-5-5 granular organic fertilizer that gives plants balanced nutrients for vigorous root growth and improved water penetration all season long. Contains only naturally occurring minerals, peanut meal and animal or vegetable meal.
  2. Container Booster Mix: Use 3 cups per square foot. This is the secret sauce! This potent, all-organic formula includes a complete diet of nutrients and trace elements to keep plants lush and healthy: concentrated plant and manure compost, washed granite, black rock phosphate, and other natural ingredients.
