Houseplant Mulch – Small bark Wood Chips for Indoor, Patio, Potting Media, and Much More! (8QTs)

Check the latest price on Amazon

Our bark mulch soil is designed to replicate the tropical climate of a forest floor. Layers of earth and rotting wood are pressed together to form our premium mulch soil. Then we take it one step further and incorporate hydro guard which includes an eco-friendly bacteria that keeps the bark wetter longer. These bacteria inhibit the growth of fungus, mold, and mildew which decreases the risk of plant diseases. The result – is a lighter-weight bark soil that holds water for longer periods of time until plants need it again.

Mulch, whether it be a small bark or large wood chips, plays an important role in the health of your plants. Mulch has been proven to keep soil moisture levels at optimum levels and to hold in soil nutrients that would otherwise be washed away from rain when not covered by mulch.

mulches are a great addition to your houseplants. When plant roots are exposed to sunlight and high temperatures, the root cells lose water which causes them to suffer.

Soil covering adds visual consistency to your indoor potted plant garden with house plant mulch while also providing a natural mulch weed cover. Soilless mixes allow you to control the balance of organic and inorganic compounds, which means it’s not only free from weeds but also free from high maintenance costs.

SOURCED SUSTAINABLY – Bark originates from sustainable pine forests in New Zealand. The mulch has a more natural look than moss and serves as a longer-lasting alternative for plants. Our bark is processed with high heat and aging to remove pathogens and allow beneficial microorganisms to flourish.
