Are your houseplants looking a bit tired, and in need of some love?
Houseplant Booster is a new product for 2022 which has been specially formulated with Biochar, along with Soil Association Approved natural biology and fertiliser to give your houseplants a new lease of life.
Biochar’s honeycomb structure ensures good airflow and drainage to promote healthy roots, and acts as a refuge for the beneficial bacteria and mycorrhizal fungi in the mix. It’s also excellent for storing moisture to prevent plants drying out and reduce watering frequency.
*Supplied in a 1 litre tub.
