For optimal results, choose a quality growing medium to grow healthy plants in containers. Soil from the ground often has too much clay content, which can impede root growth and cause other problems.

- The potting mix should be able to retain water.

- It must be loose and light enough to allow enough oxygen and air circulation.
- Check if the soil bags are soft and lightweight, not damp or tight.
- Check for ingredients, including ground pine bark, peat moss, perlite, vermiculite, fertilizer (small amount), etc.
- Look for wetting agents (limestone, for instance) to keep the bark and moss from drying out.
- You may look for organic potting soil that’s suitable for indoor and outdoor gardening.
