A bale garden uses hay or straw bales in place of soil. Seeds can be planted directly on top of the bale or seedlings can be used. Bale gardening is one way to garden if you do not have a lot of soil or space; or if your soil is hard to work. Bale gardening is also easier on your hands and wrists, especially if you have arthritis and other musculoskeletal conditions.

Most vegetables, flowers, or herbs that you want to grow in the ground, can be grown in bales. Tomatoes, peppers, cucumbers, squash, melons, broccoli, cauliflower, marigolds, petunias, basil, cilantro, and parsley are only a few of the plants that do well growing in bales.

You can make your garden into any shape you want with bales. You can make long rows by placing the bales end-to-end. Bales can be grouped together to make traditional, rectangular garden beds. You can also make your garden into a design or maze by where and how you place your bales.

General Method

Hay or straw bales need to be prepared for planting. Although bales can be used in place of soil, they do not have all the nutrients found in soil that plants need to grow. It will take about ten days to prepare your bales. There are a lot of different ways to prepare bales for planting. The steps below are a general guide.

  1. Water and keep the bales wet for the entire ten days.
  2. On the fourth day, pour five ounces (ten tablespoons) of ammonium nitrate fertilizer onto the bales. This fertilizer is often used by farmers and gardeners. Miracle Gro, Flurin, and Hibiscus are all brands that have ammonium nitrate in them.
  3. On the seventh day, pour two and one half ounces (or five tablespoons) of ammonium nitrate fertilizer on the bales.
  4. On the tenth day, pour 12 ounces (1 cup) of fertilizer with an N-P-K ratio of 13-13-13 on the bales and water. N-P-K stands for nitrogen, phosphorous, and potassium. These are nutrients that your plants need to grow. The numbers stand for how much of these nutrients is in the fertilizer by weight. You can find this information on the fertilizer's label. Some fertilizers that have this ratio are Spectrum, Jobe, Once-A-Year Plant Fertilizer, and Greenleaf.
  5. If you want to grow your garden from seed, put three inches of potting soil or top soil on top of the bales. Plant your seeds in the soil.
  6. If you are using seedlings to start your garden, you do not need to put potting soil on top of the bale. Plant seedlings by driving a trowel into the bale. Lever the trowel to force the bale slightly apart. Plant the seedling in the space you made between the flakes (sections that make up a bale). Let the bale spring back together again.
