A family is planning to build a raised planting area using a blend of peat moss, mulch, and a rich organic soil in which to grow the plants. they have been told first to place on the ground a layer of material that will allow for a proper drainage each time the plants are watered. Which of the following materials would be best to use for the first layer?

'The Recipe' for filling a raised bed these proportions are recommended: 60% topsoil, 30% compost and 10% soilless growing mix or potting soil. If you do not have access to quality topsoil, an acceptable substitute would be a 50-50 blend of soilless growing medium and compost. If you want to add peat moss to the bed, it should not be more than 20% of the total mix. Peat moss is naturally acidic and is not a good medium for growing vegetables.
So to answer the question, it would depend on what they are going to grow in the garden. Peat moss is good to use first, but not over 20% of the blend.
