Westland Houseplant Potting Mix is a peat free specialist mix that promotes healthy root growth and reduces plant stress, perfect for keeping houseplants happy. Houseplants love being in a mix that lets water run past their roots instead of sitting in a waterlogged pot. This dry, free-draining mix prevents overwatering and deters flies for healthier, happier houseplants.

It is enriched with our unique Seramis® granules. These granules absorb water and nutrients and then release them to the plant as and when they need it. This ensures your plant keeps hydrated and nourished. The added zinc complex promotes more root growth into your new potting mix, faster re-potting establishment, and also boots your plants’ resilience. This Houseplant Potting Mix is also enriched with perlite to create the perfect balance of airflow and drainage for healthy root development.

Ideal for potting or re-potting most houseplants.

How to pot and re-pot?

Repot any time of the year; spring is an ideal time during the growing season.

1. The first step is finding a pot, choose one that is slightly larger with good drainage holes.

2. Place a layer of potting mix in the base of your new pot. For best results, add a layer of Westland Hydroleca before the potting mix. Hydroleca is great at absorbing excess water, keeping plant roots dry.

3. Remove the plant from its current pot. Turn the plant sideways and gently hold by the stems or leaves. Tap the bottom of the pot until the plant slides out.

4. Place the plant into its new pot, ensuring the root ball is slightly below the rim of the new pot. Fill the pot with potting mix and water well. You can top with a layer of Hydroleca for a beautiful finish.
