A FEW POINTERS

Choose with your garden in mind.

What matters most

  • Match the exact mix with the intended plants and use.
  • Calculate the filling volume and drainage arrangement.

Where the tradeoffs land

  • Bag volume is separate from a planter's outside dimensions.
  • Seed-starting and established-container products can have different roles.
GOOD QUESTIONS

Before you head outside

What should I check before buying a multipack of mix?

Read the exact use and contents, then calculate the volume needed for the actual containers. Check how the filled setup will drain and be cared for.
