Unlike outdoor plants, houseplants are completely reliant on us to keep them well fed. Although they arrive in compost that contains low levels of fertiliser, these nutrients are quickly used up.

Fortifying Houseplant Feed & Tonic is a complete houseplant food inspired by professional formulations, that ensures your houseplants get the vital nutrients and vitamins they need to flourish. Containing 13 essential nutrients, including potassium, magnesium and iron for strong, glossy leaves and growth of more, longer lasting flowers, as well as kelp extract to stimulate cell growth.

Combine with our Perfecting Houseplant Care Mist for an additional rejuvenating boost and Protecting Bug Control Spray to protect your plants from pests, as well as strengthening plants weakened from previous attacks.

All ingredients are 100% vegan with no animal ingredients or by-products and all of our oils are Leaping Bunny certified cruelty free.

    I was surprised that I saw results from the Houseplant Feed after only a couple of uses. A bonsai that had shown no growth despite being re-potted, seemed to wake up and started to produce new shoots. Some lettuce grown from seed, developed bigger leaves that were worth eating.

    This is such good stuff. My plants were starting to look ill, with leaves going brown round the edges and now the plants in general are looking greener, healthier and lots of new leaves are sprouting.
