How to Use Water-Absorbent Material in Potting Soil
- 1). Mix a complete potting soil for potted plants. Combine quick-draining soil with organic compost, in equal parts, and use this as your own potting mix. The quick-draining soil will ensure looseness for drainage, while the organic compost provides long-term nutrition and spongy material for moisture retention. Use peat moss or sphagnum peat moss in place of organic compost, if you like. This is a good option for standard house plants that need supportive but not overly rich soil.
- 2). Plant your potted plants in pure organic compost. Put 1 inch of organic compost in the pot, then set the plant in the pot with its previous soil ball intact, and fill the pot with organic compost. The compost maintains soil moisture and adds nutrition to the entire pot. This option is best for plants that prefer highly acidic foundations with lots of organic matter.
- 3). Plant house plants in an alternative growing medium like peat moss, sphagnum peat moss, wood chips or bark. Fill the pot half-full of the growing medium, then place the plant's roots in the pot and fill the pot to 3/4 full with growing medium. This option is best for plants like orchids or succulents, which require moisture retention, quick drainage and aeration in their growing foundation.
