Horticultural Charcoal

Mosser Lee’s Organic Horticultural Charcoal is an essential soil amendment for all plants in pots without drainage holes, including terrariums and dish gardens. We make our charcoal from dying fruit trees so that no live tree is cut or used. Its excellent porosity allows absorption, retention and slow release of water and fertilizers, increasing the nutritional holding capacity of potting soils. Use to retain moisture in plant soil, beautify indoor and outdoor container plants, and improve plant drainage.

  • Eliminates stagnant water in pots
  • Absorbs water impurities
  • Sweetens soils in terrariums and pots without drainage holes
  • Improves soil oxygen levels
  • Increases beneficial microbes in soils

Because of its absorptive characteristics, charcoal has been widely used by horticulturists to help potted plants from becoming waterlogged. Over the years, charcoal has become indispensable in potting mixes when plants are placed in pots without drainage holes. Charcoal stores excess water (and liquefied fertilizer) and releases it when the roots seek nourishment as the soil dries out.

How is Mosser Lee’s Horticultural Charcoal Made?

Mosser Lee’s Organic Horticultural Charcoal is uniquely made from dead fruit tree limbs. By using tree limbs that naturally die, we help the environment by using scrap wood productively and by saving live trees, unlike many of our competitors. The manufacturing process is similar to other non-activated charcoal processes with burning kilns and sizing screens. The screens help ensure that the pieces are uniform sized. Imported.

Is Horticultural Charcoal the same as Activated Charcoal?

No. Activated charcoal is made with gas infused into the burning chamber, which is not done in making horticultural grade charcoal. The activation process allows greater absorption, but at a much higher and unnecessary cost. Activated charcoal is used in many applications including filtering in aquariums.

What plants require water control with Horticultural Charcoal?

Over-watering can kill a plant more quickly than under-watering. Some plants stress in wet soil or when over-watering could inhibit proper growth. Roots need air and over-watering conditions block the roots from getting the needed air. Waterlogged plants can also become susceptible to certain fungal pathogens. Charcoal in the soil mix should be used with most plant, but especially with:

  • African Violets
  • Orchids
  • Bonsai
  • Succulents
  • Peace Lily
  • Ficus
  • Money Trees
