Perguntas Frequentes
Q1 How deep should a raised garden bed be?
Most vegetables need 12 inches of soil depth. Root vegetables like carrots need 18-24 inches. Herbs and lettuce can grow in as little as 6-8 inches.
Q2 How many bags of soil do I need for a 4x8 raised bed?
A 4x8 foot raised bed at 12 inches deep needs about 32 cubic feet of soil, which is roughly 32 standard 1 cubic foot bags or about 1.2 cubic yards of bulk soil.
Q3 What is the best soil mix for raised beds?
A classic mix is 60% topsoil, 30% compost, and 10% perlite or vermiculite. For square foot gardening, use equal parts peat moss, vermiculite, and compost (Mel's Mix).
Q4 Is it cheaper to buy soil in bulk or in bags?
Bulk delivery is almost always cheaper for beds larger than 4x4 feet. A cubic yard of bulk soil costs $30-55, while the same volume in bags costs $80-150.
Q5 How much does raised bed soil weigh?
Soil weighs approximately 75 lbs per cubic foot when moist. A 4x8x1ft bed holds about 32 cubic feet of soil, weighing roughly 2,400 lbs (1.2 tons).
Q6 Can I use hugelkultur to save on soil?
Yes. Filling the bottom third of a deep bed with logs, branches, and leaves reduces soil needed by 30% and improves long-term fertility as the wood decomposes.
