Potting Mix for Orchids UN 5 L (FH ZS 5L) — Ready Orchid Substrate, 5 L

UN Potting Mix for Orchids 5 L is a ready-to-use substrate formulated specifically for potted and epiphytic orchids. The mix is designed to provide balanced aeration and drainage while offering stable mechanical support for root systems of common indoor species such as Phalaenopsis. Packaged in a 5 litre volume, it is intended for repotting, periodic substrate refresh and routine indoor cultivation where a coarse, free-draining medium is required.

Advantages

The substrate combines coarse components that promote air circulation around roots and rapid excess water removal to reduce the risk of root rot. Its structure maintains stable support for plants while allowing easier root inspection and maintenance during repotting. The ready-to-use format eliminates the need for on-site mixing and is suitable for immediate planting or transplanting.

Suitable for

• Repotting Phalaenopsis and other common epiphytic orchids
• Routine substrate refresh for indoor orchid collections
• Potted orchids grown on windowsills, balconies or under grow lights
• Home growers who prefer a pre-mixed coarse orchid medium

Key specifications

• Volume: 5 litres of ready-to-use orchid substrate
• Structure: coarse, free-draining components to support aeration
• Use: formulated for epiphytic and potted orchid varieties
• Application: suitable for repotting and routine substrate replacement

How to use

Remove the plant gently from its current container and shake or wash away old substrate from the roots as needed. Trim any dead or rotten roots before planting. Place a layer of the UN potting mix in the new pot, position the orchid so roots sit comfortably against the sides, then fill around the roots without compacting the medium. Water lightly after potting to settle the substrate, then resume regular watering and fertilizing appropriate for the orchid species.

Usage recommendations

For best results, select a pot with adequate drainage and avoid compacting the substrate. Water according to the species’ requirements—typically allowing the medium to dry slightly between waterings—and use a balanced orchid fertilizer at reduced strength during active growth.
