No matter how good a compost is, you're always running the risk of root rot if water begins to accumulate in the pot's base. It’s dark in colour and highly porous, which has meant that houseplant growers have started using it as a substrate in prop boxes and as a mineral substate in the same vein as leca and pon.

Always check the provenance of your coir - Fertile Fibre is a responsible supplier in the UK, and check out Epic Gardening’s coir guide for suggestions for US suppliers.From potting mix and soil to liquid plant food, we have everything you need to get your garden off on the right foot.

These work well for some plants but they break down too quickly to be of use for cacti and succulents. It's far better to water the plant 7 Litres in one go per week, instead of 1 Litre per day for the same period of time. Our mix is made using a unique blend of four key ingredients: coco-coir, perlite, pine bark, and worm castings.

Our houseplant compost gives you an all-organic composting solution for use with a wide variety of indoor plant species.Introducing our premium houseplant potting mix, specially formulated to provide your indoor plants with the perfect growing medium for healthy and vibrant growth. Artstone planters include a non-removable water reservoir, which raises the internal base height of the planter. Liners come in various sizes to fit the internal dimensions of the pot and can be trimmed down to size to create an unobtrusive barrier for the plant and soil to be potted into, whilst protecting the pot from unsightly calcium or fertiliser deposits from the soil. Liners can also be cut down to size with scissors for a neater fit if they bulge inwards slightly at the top. These planters work best with the plant re-potted directly into them rather than left in their grow pots.
