How to Use

Simply squirt four pumps of feed into 1L of water and mix well for ten seconds. Water the plant as you would normally, ensuring the entirety of the soil has become moist. We'd recommend feeding your green pals every forth water in the spring and summer, before reducing this to every sixth water in the colder months!

Unlike outdoor plants, houseplants are completely reliant on us to keep them well nourished. Although they arrive in compost that contains low levels of fertiliser, these nutrients are quickly used up. That’s why you need to use a good quality houseplant feed, to ensure your houseplants are getting the vital nutrients and vitamins they need to flourish. Less nutrients in the plant will ALWAYS result in a weakened plant, becoming more susceptible to pests, diseases and death.

Inspired by formulations used by the professionals, our Premium Houseplant Tonic contains thirteen perfectly balanced essential nutrients designed to encourage strong, glossy leaves and the growth of longer lasting flowers.
